Ashtakavarga calculator

What this long-form adds to the calculator above

The calculator above already tells you what a bindu is, how the tables are applied, and why the grand total is always 337. This section goes further in four directions: where the system comes from in the classical texts and how those texts differ from each other, a line-by-line trace of real engine output so you can check a cell by hand, how to read each part of the result without over-reading it, and what this app does and does not do with the numbers elsewhere.

Every number quoted below comes from running the same engine function the calculator calls, on the same sample birth the page uses: 14 August 1994, 06:42, Ahmedabad. Nothing is illustrative. If you want the chart those numbers sit on, the birth chart calculator gives the same signs and houses from the same inputs.

Where Ashtakavarga comes from

Brihat Parashara Hora Shastra opens its treatment in Chapter 66 with a complaint. Maitreya tells Parashara that the effects of grahas and houses have been described by many sages, but that the descriptions contradict each other once the movement of the grahas is taken into account, and asks for a method that even an ordinary student could use to judge good and difficult periods from the grahas in transit (Sl. 1-4). Parashara agrees that the question is a good one and promises a method "in which there will be no contradictions" (Sl. 5-6).

He then draws a line through the subject. Jyotisha, he says, has two parts, general and particular (Sl. 12). The general part is everything that came before: a house does well when benefics occupy or aspect it and the grahas concerned are well placed, and poorly when the reverse holds (Sl. 7-11). Ashtakavarga is the particular part. Its premise is in Sl. 13-15: just as houses are judged from the Lagna and from the Moon, they can be judged from each of the grahas in turn. So for each graha, the places counted from the seven grahas and the Lagna - eight starting points - are marked as either supportive or unsupportive, and the chart is judged from the tally.

The translator's note to those verses gives the plain meaning of the name: a group of eight things. It is "the combination of the good and bad positions of a Grah with reference to the seven Grahas and Lagn", with the Lagna treated as if it were a graha for this purpose.

Saravali gives the same system two chapters. Chapter 53 states its purpose in one sentence - it exists to evaluate day-to-day effects "due to planetary transits" - and credits the Yavanacharyas with explaining it (Sl. 1) before listing a table for each graha. Chapter 54 then describes how to read the result. So both classical texts in this app's corpus frame Ashtakavarga first as a transit tool, which is why it sits next to Gochar in practice, even though the calculator on this page is computed entirely from the birth chart.

The tables, and where the sources differ

The engine holds seven tables, one per graha from the Sun to Saturn, each with eight rows, one per reference point. Its code comment cites them to S. Kannan's Fundamentals of Hindu Astrology, Chapter XXXII, pages 119-121, the "Suddha Bindu" or unreduced tables, checked against BPHS Ch. 66; since October 2026 three entries follow BPHS where its two lists of places agree (described below). Counting the entries in each table gives the fixed share each graha contributes, whatever the chart:

Two things follow from that table. First, the grahas do not start level: Jupiter's row will always hold 56 bindus across the twelve houses and Mars's or Saturn's only 39, so a 4 in Saturn's row is above its own average of 3.25 while a 4 in Jupiter's row is below its average of about 4.7. Second, 45 of the 337 bindus are anchored to the rising sign and the other 292 to the signs the seven grahas occupy. That split matters for birth-time sensitivity, covered further down.

For this page the Sun's table was checked against the primary source in a way that does not depend on reading the same list twice. BPHS Ch. 66 Sl. 16 does not list the Sun's supportive places; it gives the number of reference points that withhold support at each place - five at the 1st, 2nd, 3rd, 8th and 12th, four at the 4th and 7th, three at the 6th and 9th, six at the 5th, two at the 10th and one at the 11th. Subtracting each from eight and comparing with the engine's table gives a match at all twelve positions, and the supportive counts add to 48. Saravali Ch. 53 Sl. 2 lists the Sun's table place by place and it too is identical to the engine's.

The sources are not identical everywhere, and it is better to say so than to imply a single agreed table. BPHS Ch. 66 gives each table twice, once as the supportive places (Sl. 43-60) and once as the unsupportive ones (Sl. 16-42). Where those two lists agree with each other and differ from the Kannan figures the engine started from, the engine now follows BPHS (October 2026): Saturn's table takes the 12th from Mercury and drops the 5th from Venus, Venus's table takes the 4th from Mars instead of the 5th, and the Moon's table takes the 9th from the Moon instead of the 9th from Mars. The Saravali translation in this corpus agrees with BPHS on the Saturn and Venus entries; it still differs on one, omitting the 6th from the ascending sign in Saturn's table. Where BPHS's two lists contradict each other, the engine keeps its earlier entry. Every one of those changes swaps one place for another inside the same table, so the table totals and the 337 total are unchanged, and the engine checks that total on every chart.

BPHS also describes an eighth table, the Ashtakavarga of the Lagna itself (Ch. 66 Sl. 65-68). The engine does not compute it. The Lagna takes part as a giver of bindus in all seven tables but has no row of its own in the result, which is the same arrangement Saravali Ch. 53 uses. Rahu and Ketu have no part in either text. The sources page lists the books behind each engine.

One cell traced by hand

The sample chart has Leo rising, with the Sun and Mercury in Cancer (12th house), Venus in Virgo (2nd), the Moon and Jupiter in Libra (3rd), Saturn in Aquarius (7th) and Mars in Gemini (11th). You can confirm the rising sign with the Lagna calculator. The engine reports 7 bindus for the Sun in the 8th house, which is Pisces - the highest cell in the whole result. Here is where each of the seven comes from, using the Sun's table.

The counting is inclusive, as everywhere in this system: the sign a reference point sits in is its own 1st. Notice also what the trace does not use. No degree, no nakshatra, no dignity, no retrogression, no aspect. Each reference point is reduced to a sign, and each sign either is or is not on a fixed list. That is the whole computation, repeated 337 times.

It also explains why a single high cell is not, by itself, a statement about a graha's condition. The Sun in this chart sits in the 12th house, in Cancer. Its 7 is in Pisces, a sign the Sun does not occupy. The cell says that if the Sun were moving through Pisces, seven of the eight natal reference points would be placed supportively relative to it. That is a statement about a sign as seen from the birth chart, which is exactly why the classical texts turn straight to transits.

The full sample result

The page above quotes four house totals from the sample. Here is the whole grid as the engine returns it, with houses down the side and the sign each house falls in for a Leo ascendant.

Read down a column and you have one graha's Bhinnashtakavarga; read the last column and you have the Sarvashtakavarga. The column sums are the fixed table totals from the earlier section, and the last column adds to 337, so the result's completeness flag is true and its note says so.

Reading the Sarvashtakavarga

BPHS Chapter 72 calls the combined grid the Samudaya, or aggregational, Ashtakavarga (Sl. 1-2) and gives the one piece of interpretation that is most often repeated. A sign with more than 30 marks "gives favourable effects", one with between 25 and 30 gives medium effects, and one with fewer than 25 gives adverse effects (Sl. 3-5). The following verse applies the same three bands to the twelve houses: more than 30 advances what the house stands for, 25 to 30 is medium, fewer than 25 and its effects "get damaged" (Sl. 6-6.5).

Applied to the sample, that sorts the houses like this. The translation does not say which band the exact values 25 and 30 belong to, so they are placed in the middle band here, which is the literal reading of "more than 30" and "less than 25".

Since 337 divided by twelve is just over 28, the middle band is centred on the average and most houses in most charts will fall into it. That is the honest shape of this data: a few houses stand out, the rest are ordinary. In the sample the clear outlier is the 10th house at 36, with the 1st at 32.

Three refinements in the same chapter are worth knowing because they stop a naive reading.

• The 6th, 8th and 12th houses are read the other way round. The translator's note to Sl. 6-6.5 draws the inference that fewer than 25 in those houses is favourable and more than 25 is not, because a strong difficult house is not good news. In the sample the 6th has 24, which that reading counts as favourable, while the 8th has 29 and the 12th 28.
• There is a named comparison across the 10th, 11th, 12th and 1st. Sl. 7-8 say that when the 11th holds more than the 10th, the 12th holds fewer than the 11th, and the Lagna holds the most of all, the chart is read as one of wealth and comfort. The sample fails each test: its 11th (28) is below its 10th (36), its 12th (28) is not below its 11th, and the largest total is in the 10th, not the 1st. Failing a named combination is not a negative verdict; it means only that this particular verse does not apply.
• The bands are used for choosing times as well as for reading houses. Sl. 3-5 advise starting auspicious undertakings when the Moon is in the sign with the most marks. For this chart that is Taurus.

Reading a single graha's row

Each cell in a graha's own row runs from 0 to 8, so 4 is the midpoint. Saravali Chapter 54 reads the cell for the sign the graha actually occupies at birth. Its general rule (Sl. 2) climbs from complete absence at the bottom to 8 at the top, and the per-graha lists that follow (Sl. 3-9) all share one feature that is worth more than the individual phrases: 4 is the neutral point. For the Sun, 4 is "neither gainful nor losing"; for Jupiter, "no loss, no gain"; for the Moon, an "equilibrium of happiness and grief"; for Venus, an "equality of inauspicious and auspicious results". Five and above are described in increasingly favourable terms and three and below in increasingly difficult ones.

In the sample, the cell under each graha for the house it occupies reads as follows.

Saravali attaches period-specific results to each count - royal favour, loss of money, particular ailments - written for a court society many centuries ago. Those phrases are not predictions this app makes, and the bodily ones are not medical advice. The usable part is the direction: Mars is the one graha here sitting on a below-midpoint count in its own row, which is one more input alongside its sign, house and Shad Bala, not a conclusion in itself.

BPHS Chapter 70 gives each row a subject. The Sun's Ashtakavarga is consulted for the self, vitality and the father; the Moon's for the mind and the mother; that of Mars for siblings, courage and land; Mercury's for dealings, livelihood and friends; Jupiter's for learning, children and wealth; that of Venus for marriage, comforts and conveyances; Saturn's for longevity, livelihood and losses (Sl. 1-6). The chapter then reads each row mostly by transit, which is the next section.

What the classical texts do with the rows: transits

Saravali Ch. 53 Sl. 9-10 gives the working rule in one line: a graha transiting signs with more benefic dots shows auspicious results, and one transiting signs with fewer shows the opposite. BPHS Ch. 66 Sl. 70-72 says the same from the other side - whenever the graha whose Ashtakavarga it is passes through the places marked unsupportive, it gives unfavourable results, and in the other places favourable ones.

Chapter 70 then applies it graha by graha. Auspicious functions are to be avoided in the month when the Sun transits a sign with more unsupportive marks in the Sun's own Ashtakavarga, and performed when it transits one with more supportive marks (Sl. 19-20). The same is said of the Moon in the Moon's row (Sl. 21-23). When Mars passes through a sign that is high in Mars's row there are gains of land and happiness through siblings (Sl. 24-27); when Venus passes through a sign high in Venus's row, gains of wealth and comforts (Sl. 34-36). And for Saturn: results are favourable when Saturn transits signs with more supportive marks in Saturn's Ashtakavarga and difficult when it transits signs with more unsupportive ones (Sl. 43-44).

That last rule is the practical reason people look up this table. Saturn spends about two and a half years in a sign, so its own row is a rough map of which of those long stretches the birth chart supports. In the sample, Saturn's row is highest in Leo (6) and lowest in Virgo (1), with Libra, Gemini and Cancer at 3 and Scorpio and Capricorn at 2. The Sade Sati and Ashtama Sani calculators date Saturn's named transits from the Moon; Saturn's row is the classical way of asking how heavily a given one is likely to weigh. The app does not combine the two automatically, so that comparison is yours to make. The Saturn guide covers the graha itself.

The reductions: Trikona and Ekadhipatya

BPHS does not stop at the raw rows. Chapters 67 and 68 describe two successive reductions, or shodhanas, applied to each graha's row. The calculator returns the first of them alongside the raw rows; the page above mentions that in a single sentence, so here is what it actually does.

Trikona Shodhana (BPHS Ch. 67)

The twelve signs fall into four groups of three that stand in trine to each other: Aries, Leo and Sagittarius; Taurus, Virgo and Capricorn; Gemini, Libra and Aquarius; Cancer, Scorpio and Pisces (Sl. 1-2). These groups are fixed in the zodiac and do not depend on the ascendant. Within each group, for each graha's row, the engine applies the three rules of Sl. 3-5 exactly as written:

1. 1.If any of the three signs has no bindus, the group is left as it is.
2. 2.If all three hold the same non-zero number, all three become zero.
3. 3.Otherwise the largest count is kept, and each smaller count is replaced by the largest minus itself.

The Sun's row in the sample shows rule 3. In the fire signs it has Aries 3, Leo 5, Sagittarius 4. Leo keeps its 5; Aries becomes 5 - 3 = 2; Sagittarius becomes 5 - 4 = 1. In the water signs it has Cancer 4, Scorpio 3, Pisces 7: Pisces keeps 7, Cancer becomes 3 and Scorpio 4. Working all four groups through by hand gives a reduced row summing to 36, which is what the engine returns.

Mars's row shows rule 2. In the air signs it holds Gemini 2, Libra 2, Aquarius 2, and in the water signs Cancer 3, Scorpio 3, Pisces 3. Both groups are level, so all six cells go to zero and Mars's row drops from 39 to 21. Across the seven grahas the sample's reduced rows sum to 36, 44, 21, 38, 40, 44 and 33.

It helps to see what kind of operation this is. A reduced cell is no longer a count of supporting reference points; rule 3 can turn a 3 into a 4 and a 4 into a 3, as it does for Scorpio and Cancer above. The reduction expresses each sign relative to the strongest sign of its trine. It is an intermediate figure in a longer classical calculation, not a better version of the raw bindu, and it should not be read against the 0-to-8 scale or the 25 and 30 bands.

Ekadhipatya Shodhana (BPHS Ch. 68)

The second reduction works on the pairs of signs that share a lord: Aries and Scorpio (Mars), Taurus and Libra (Venus), Gemini and Virgo (Mercury), Sagittarius and Pisces (Jupiter), Capricorn and Aquarius (Saturn). Leo and Cancer have one sign each and are left alone (Sl. 5). It runs only when both signs of a pair still hold a number after the Trikona step, and its outcome depends on whether either sign has a graha in it: both occupied, no change; neither occupied, both take the smaller number, or zero if they are equal; one occupied, the empty sign takes the difference, or zero if they are equal, and the occupied sign is untouched (Sl. 1-5). The engine implements this as a separate function, and its output is part of the signed-in Kundali rather than this public calculator. For the sample its rows sum to 29, 31, 21, 31, 27, 34 and 27.

What comes after, and is not computed

In BPHS the reductions exist to feed a further step. Chapter 69 multiplies each reduced figure by a fixed weight for its sign and, where a graha is present, a weight for the graha, and sums the products into a Pinda. Chapter 70 multiplies that by a bindu count and takes remainders on division by 27 and by 12 to name a nakshatra and a sign whose transit by Saturn is then read for particular relatives (Sl. 1-6 onward). Chapter 71 converts the bindus of every table into a span of life. None of that is in this engine. The Pinda step is not implemented, and the app does not estimate longevity or date events in relatives' lives by any method. That is a deliberate boundary, and it is the reason the reduced rows are shown as what they are - the documented intermediate step - without a verdict attached.

How this app uses the numbers elsewhere

The calculator returns the grid and stops. Three other parts of the app read the same Sarvashtakavarga, each in a documented way.

• Strong and weak houses. The signed-in Kundali flags a house as standing out when its total is at least 15 percent above the chart's own average, and as low when it is at least 15 percent below. Because the total is always 337, the average is always 28.1, so in whole numbers that means 33 or more and 23 or fewer. For the sample the engine returns one strong house, the 10th at 36, and two weak ones, the 3rd and 7th at 23; the 1st at 32 falls just inside the ordinary range.
• Today's transits against your houses. The same view takes each of the seven grahas' current sign, counts its house from your ascendant, and grades that house's Sarvashtakavarga total with the same thresholds as favourable, neutral or testing. Run for the sample against the sky of 6 October 2026, every graha landed on a house between 23 and 29 bindus; five came back neutral and two, Mercury and Venus in the 3rd at 23, testing.
• Career and money scoring. The career and money calculator scores each dasha lord on six terms, one of which is the Sarvashtakavarga total of the house the lord occupies, measured against 28 and scaled so that ten bindus above or below reaches the limit of plus or minus one. A lord in the sample's 10th house would pick up +0.8 on that term. The feature page explains the other five.

Two honest differences from the classical texts are worth stating. The app's threshold is tighter than BPHS Ch. 72's: BPHS calls anything over 30 favourable and under 25 adverse, while the engine waits for 33 and 23. The engine's comment gives the reason - different popular sources quote different absolute cut-offs, so it measures each chart against its own average rather than assert one. And the app's transit reading uses the combined total for the house, whereas BPHS Ch. 70 reads each graha against its own row. Under the classical rule, Saturn on 6 October 2026 was in Pisces, where the sample's Saturn row holds 4, and Jupiter was in Cancer, where the sample's Jupiter row holds 6. You can make that reading yourself from the calculator's output; the app does not make it for you.

Birth-time sensitivity, measured

The page above says that an uncertain birth time shifts every house number. The sample is an unusually sharp demonstration, because its ascendant is at 2 degrees 20 minutes of Leo. A minute-by-minute scan of that morning puts Leo's rise at 06:32 at Ahmedabad, ten minutes before the stated birth time, and Virgo's at 08:44.

An hour earlier the same birth has an 11th house of 37, a 7th of 19 and a 12th of 22, which under the app's thresholds would mean three strong houses and three weak ones, against one and two. Nothing about the grahas changed between those rows; they are all in the same signs.

The change is more than a renumbering. If only the labels moved, Leo would hold the same total whichever house it became. It does not: Leo holds 32 with Leo rising and 30 with Cancer rising, Sagittarius goes from 30 to 34, Capricorn from 24 to 19. That is the Lagna's 45 bindus being redistributed from a new starting sign, while the other 292 stay where the grahas put them.

Three practical conclusions follow.

• Within one rising sign, the result is completely stable. From 06:32 to 08:43 on that morning every cell in the table is identical, because nothing in the method reads a degree. A birth time that is uncertain by twenty minutes in the middle of a rising sign costs nothing here.
• Near a boundary, treat the result as two candidates. The rising sign changes roughly every two hours, and that morning's scan shows intervals from about ninety minutes to two and a quarter hours. If your ascendant degree is very low or very high, run the calculator for both signs and see what holds in both. Birth time unknown covers what else survives without a reliable time.
• The Moon is the only graha likely to change sign within the day. On the sample date it moved from Libra to Scorpio at 15:49. A graha changing sign moves its own share of the 292 graha-anchored bindus, so a birth late in the day with an uncertain date boundary has two sources of movement, not one.

Without both a time and a resolved place the calculator does not guess; it reports that the result is unavailable and why. The accuracy page and the methodology describe how the positions themselves are computed and how precise they are. For this calculator, precision of position matters only at sign boundaries, since a graha a few arcminutes inside a sign contributes exactly as one in the middle of it.

What the result cannot tell you

• It does not weigh the giver. A debilitated Saturn and an exalted one give the same bindus from the same sign. BPHS itself places Ashtakavarga beside the general judgment of dignity and placement (Ch. 66 Sl. 7-12), not in place of it.
• It does not say when. A high 10th house is a standing feature of the chart. Timing comes from the dasha running and the transits over it; the Vimshottari dasha calculator and the Mahadasha guide cover the first of those. BPHS Ch. 70 makes the same point repeatedly: a difficult transit reading is tempered or confirmed by whether the dasha then running is favourable.
• It cannot compare people. Every chart has 337 bindus. Nobody has more Ashtakavarga than anybody else; the only question is how the same total is distributed across twelve houses.
• It is not a strength score for a graha. A graha's row describes signs, not the graha's own condition. For that, see Shad Bala and Vimshopaka Bala, which measure different things again.

If the house totals raise questions about a particular area, the learn pages on each house, such as the 10th house, describe what the house stands for, and Timing shows how dasha and transit are brought together. More tools are listed on the calculators page.

More questions

Is a bindu good or bad? I have seen both said.

Both are said because two naming conventions exist. In the BPHS translation the favourable mark is a rekha and the unfavourable one a bindu (Ch. 66 Sl. 69). In Saravali and in the Kannan tables this engine uses, the favourable mark is the bindu. On this site a bindu is always a point of support, and more is more supportive.

What counts as a high or low house total?

BPHS Ch. 72 Sl. 3-6 gives the classical bands: more than 30 favourable, 25 to 30 medium, fewer than 25 adverse. This app's own flag is stricter - 33 or more, 23 or fewer - because it measures a house against the chart's average of 28.1 with a 15 percent margin. A house can therefore be favourable by the classical band and still not flagged by the app, as the sample's 1st house at 32 is.

Is a low total in the 8th or 12th house a problem?

The translator's note to BPHS Ch. 72 Sl. 6-6.5 reads it the other way: for the 6th, 8th and 12th, a total under 25 is taken as favourable and a higher one as unfavourable, since those houses stand for difficulties. The calculator shows the same plain number for every house and leaves that inversion to the reader.

Why does Jupiter's row always look fuller than Saturn's?

Because the tables are unequal. Jupiter's table hands out 56 bindus on every chart and Saturn's 39, so Jupiter averages about 4.7 a house and Saturn 3.25. A 4 in Saturn's row is above its own average; a 4 in Jupiter's is below. Compare a cell with others in the same row before comparing across rows.

How do I use this for Saturn's transit?

Find the sign Saturn is in, then read that sign's cell in Saturn's own row. BPHS Ch. 70 Sl. 43-44 reads a higher count as a better-supported transit and a lower one as a harder one. Then set that beside the Moon-based reading from the Sade Sati calculator and the dasha running at the time. No single one of the three settles the question.

Two apps gave me different bindus for the same birth. Why?

Three causes are worth checking. A different rising sign, from a different birth time, place or ayanamsa, changes the whole grid. A graha that sits near a sign boundary may fall on either side depending on the ephemeris. And the tables themselves vary slightly between sources - the engine follows BPHS Ch. 66 in a few entries where that text's two lists agree (Saturn's, Venus's and the Moon's tables), which differ from tables printed in many modern manuals, and the Saravali translation in this app's corpus differs from the engine in one entry of Saturn's table. A total of 337 confirms a table set is internally complete, not that two sets agree.

Does a high house total mean something good will happen there?

No. It means that, under these fixed tables, more of the chart's eight reference points stand in a supportive relation to that house. The classical texts read that as the house being easier to get results from, and they still require the dasha and the transits of the time before saying anything about an event. The calculator reports the count and makes no forecast.
