Ashtakavarga Cluster · Score Reading

The Ashtakavarga score, the 0-to-8 BAV scale, the 337 SAV total and the per-house reading bands.

An Ashtakavarga score is a structural strength reading built from eight independent reference points evaluating every sign on the chart. The Bhinna value (BAV) is the per-planet per-sign score on a 0 to 8 scale. The Sarva value (SAV) is the per-sign sum across the seven planets. Across the 12 signs the SAV totals exactly 337 on any correctly computed chart, fixed by the classical contribution tables in BPHS Chapter 66. The 30-bindu strong threshold, the 28-bindu average and the 25-bindu weak threshold are the conventional reading bands the classical literature applies house by house. This article walks through what each layer of the score is, how to read the bands, what high and low scores predict for a chart and how the score filters slow-transit and Vimshottari-dasha signals into chart-specific timing.

What an Ashtakavarga score actually is

The Sanskrit name decomposes as ashta (eight) plus varga (class or division). The system evaluates every sign on the chart from eight independent reference points and counts how many of the eight find the sign favourable for the planet being scored. The count is the score. Because there are eight contributors the score ranges from 0 (no contributor finds the sign favourable) to 8 (all eight do). In practice scores cluster between 2 and 6 across the 12 signs of any chart, with the extremes at either end rare.

The per-planet per-sign score is the Bhinna Ashtakavarga (BAV) value. It tells you how strongly one specific planet is supported at one specific sign on this chart. The second-level aggregation sums the seven planetary BAVs at each sign into the Sarva Ashtakavarga (SAV) value. The SAV tells you how strongly the sign itself is supported across the planetary system, irrespective of which specific planet is acting on it. Reading the Ashtakavarga score in operational terms means reading both layers: BAV for per-planet strength and SAV for per-sign strength.

The eight contributors that build the score

The eight contributors are the seven classical planets plus the ascendant (lagna). Each of the seven planets has its own contribution table in BPHS Chapter 66 that specifies, from each of the eight contributors, which positions (counted as houses from the contributor) are favourable for the planet being scored. To compute the BAV of a sign for Jupiter, you check each of the eight contributors against Jupiter's table and count how many of them find the sign favourable from their position on the chart.

The Jupiter contribution table illustrates the structure. The numbers in the third column are the total bindus Jupiter receives across the 12 signs from each contributor.

Contributor	Role at Jupiter's table	Total bindus across the 12 signs
Sun	One of eight evaluators	7
Moon	One of eight evaluators	9
Mars	One of eight evaluators	7
Mercury	One of eight evaluators	8
Jupiter	Self-evaluating	9
Venus	One of eight evaluators	7
Saturn	One of eight evaluators	5
Lagna	One of eight evaluators	4

The 7 + 9 + 7 + 8 + 9 + 7 + 5 + 4 contributions sum to 56, which is Jupiter's total bindu count across all 12 signs. Each of the seven planets has a similar fixed total determined by its own BPHS Chapter 66 table.

The fixed per-planet totals and the 337 SAV invariant

The seven planetary BAV totals are fixed and do not vary between charts. They are determined by the BPHS contribution tables.

Planet	Total bindus across the 12 signs (Bhinna)
Sun	48
Moon	49
Mars	39
Mercury	54
Jupiter	56
Venus	52
Saturn	39
Total	337

The 337 total is invariant. What varies between charts is how the 337 bindus distribute across the 12 signs based on the natal positions of the eight contributors. A sign with many contributors donating bindus to it receives a high SAV. A sign with few contributors donating receives a low SAV. The 337 mathematical average per sign is 337 divided by 12 = 28.08 bindus, which is the chart-side baseline for per-sign reading.

Rahu and Ketu are not contributors in the canonical eight-source method. Some practitioners include them in extended versions but the standard reading uses only the seven planets plus the lagna. If your software produces an SAV total that is not 337, the software is using a non-standard contributor set.

The BAV reading bands (0 to 8 scale)

The BAV reads the strength of one specific planet at one specific sign on this chart. The classical bands sit at the 4-bindu midpoint of the 8-point scale.

BAV at a sign	Band	Reading for the planet at that sign
7 to 8	Very strong	Almost all contributors support the planet at this sign. Transits and dasha activations of this planet through this sign deliver the planet's significations with minimal friction.
5 to 6	Strong	More than half the contributors support the planet. The default reading for the planet at this sign is constructive. Most classical texts use 5 as the threshold for strong.
4	Average	Half the contributors support the planet. The sign neither obstructs nor amplifies the planet. The dasha and transit overlays carry most of the timing signal.
3	Weak	Below half. The sign provides less support than average. The planet's significations face mild friction at this sign on this chart.
0 to 2	Very weak	The sign actively under-supports the planet. Slow transits through this sign are the classical caution windows. Dasha periods of this planet through this sign deliver the planet's most challenged expression.

The BAV bands are read per-planet because the score is meaningful only against the planet being scored. A sign with 7 Jupiter bindus is strong for Jupiter; the same sign might have 2 Saturn bindus, making it weak for Saturn. The chart owner's experience of slow Jupiter transits and slow Saturn transits through that same sign diverges accordingly.

The SAV reading bands (per-sign and per-house)

The SAV reads the aggregate strength of one sign across the seven planets. The reading bands sit around the 28.08 mathematical average.

SAV at a sign	Band	Reading for the house this sign occupies on the chart
30 or more	Strong	The sign is structurally supported across multiple planetary themes. Slow transits across it read constructively. The house this sign occupies on the chart has structural support across the life.
28 to 29	Average	The sign performs at the chart mathematical average. The dasha and transit overlays carry most of the reading signal.
25 to 27	Mildly weak	Below average. The house requires deliberate cultivation. Not blocked but not structurally supported either.
Below 25	Classically weak	The classical caution band. Themes of the house tend to require sustained effort to produce outcomes that other houses produce by default.

The SAV bands are read through the house the sign occupies on this chart. A sign with 34 SAV in the 10th house reads as career-axis support across the life. The same 34 SAV in the 7th house reads as partnership-axis support. The house position is the lens through which the SAV strength operates.

The dusthana inversion for the 6th, 8th and 12th houses

The 6th, 8th and 12th houses are classically difficult (dusthana). The 6th carries conflict, debt, disease and adversaries. The 8th carries transformation, crisis, joint resources and longevity disruption. The 12th carries loss, dissolution, expense, foreign places and withdrawal. For these houses the qualitative reading of high and low SAV inverts.

High SAV in a dusthana house means the contributors collectively donate generously to the difficult sign, which means the difficult themes activate frequently with structural support across the life. The chart owner experiences more conflicts that develop into structured situations, more transformations that follow through with traction, more expense and foreign displacement that consolidates rather than passes. Read against the constructive frame the threshold rule sets up, that is not the desired outcome. The classical reading inverts. High SAV in a dusthana house reads as unfavourable. Low SAV in a dusthana house reads as favourable because the difficult themes activate less frequently and with less structural support.

The 28-bindu mathematical baseline does not move for the dusthana houses. The numerical bands stay at 30/28/25. The qualitative reading direction reverses.

How the score filters transit and dasha signals

The score is structural. The Vimshottari mahadasha and the slow-transit calendar are dynamic. The score is the chart-side filter that converts the universal calendar into chart-specific timing.

For a transit reading, look up the BAV of the transiting planet at the sign it is currently moving through. A BAV of 5 or more on this chart means the transit reads as a constructive phase for the planet's signification themes. A BAV of 2 or below means the transit reads as a friction phase. Add the SAV of the sign for the broader reading. A planet transiting a sign where its own BAV is 7 and the sign's SAV is 32 is the cleanest single transit signal in the framework. The same planet transiting a sign where its BAV is 1 and the sign's SAV is 22 is the tightest caution flag.

For a dasha reading, look up the BAV of the dasha lord at its natal sign on the chart. A Jupiter mahadasha starting with Jupiter at a sign of BAV 6 reads more constructively than a Jupiter mahadasha with Jupiter at a sign of BAV 2 on the same 16-year period. The dasha lord's natal BAV modulates the entire arc of the mahadasha.

The strongest single-event signal in the framework is three-layer agreement. Layer one: the SAV of the relevant sign supports the theme (or the dusthana inversion supports it). Layer two: the relevant house lord runs its Vimshottari mahadasha or antardasha. Layer three: a benefic planet transits a sign where its own BAV is 7 or 8. When all three layers point at the same window, the prediction reads as the highest confidence the system supports.

A worked example: reading the 10th house career axis

A generic chart with the following structural readings illustrates the operational sequence.

10th house SAV: 34 bindus (strong band).
10th lord: Saturn, placed in the 9th house with Saturn BAV 6 at that sign.
Approaching Saturn mahadasha sub-period Saturn antardasha.
Within that window, transit Jupiter at high Jupiter BAV (7 bindus) crosses the 10th house sign for 13 months on the standard 12-year cycle.

The reading layers are these. Structural: the 10th house at 34 SAV is in the strong band and the 10th lord Saturn at its natal sign with BAV 6 is structurally supported. Dynamic: the Saturn-Saturn antardasha activates Saturn (the 10th lord) at maximum intensity. Transit: Jupiter at high BAV passing through the 10th house sign adds benefic reinforcement for 13 months. The three-layer overlap is the chart's strongest possible career-window configuration. The classical reading would identify this window as a structural moment for career consolidation, recognition or institutional promotion.

A second chart with 10th SAV 22, 10th lord Saturn at BAV 2 and the same Jupiter transit at low Jupiter BAV reads identically by the calendar but differently by the chart. The Jupiter transit happens on the same dates. The chart's structural and dynamic context does not support converting the generic opportunity into sustained advancement.

What the score does not do

The Ashtakavarga score is a structural filter, not a predictor of specific events. A high SAV in the 10th house tells you the career axis is structurally supported. It does not name which job, which sector, which company or which year. The score modulates other timing signals. It does not replace them.

The score is computed from the natal chart and does not change over a lifetime. The static nature is the strength (a stable structural reading against which dynamic events can be measured) and the limit (the score does not capture changes the chart owner experiences as a function of mahadasha and transit progress). Combine with the Vimshottari dasha and the slow-transit calendar for a dynamic reading.

The score depends on accurate birth time for the ascendant calculation. A 60-minute birth time error can shift the ascendant by 15 degrees and change which sign occupies each house, which changes the entire per-house SAV reading. For charts with unverified birth times, the SAV-by-house values should be treated as provisional and rectification work should precede the chart reading.

Calibration status

The article documents the classical Ashtakavarga methodology. The contribution tables, the per-planet totals (Sun 48, Moon 49, Mars 39, Mercury 54, Jupiter 56, Venus 52, Saturn 39 = 337) and the reading bands (30/28/25 for SAV, 5/4/3 for BAV) are the classical reading rules as set out in BPHS Chapters 66 and 67, Phaladeepika and Sarvartha Chintamani. The Tempora calibrated signature library (Note 005, 9 transit signatures) does not currently include Ashtakavarga-threshold signatures. The cluster presents the score as the tradition's own framework rather than as Tempora's calibrated output. Calibrating Ashtakavarga signatures against the historical event corpus is open work scheduled after the existing signature library is stable.

FAQ

What does an Ashtakavarga score actually mean?

Ashtakavarga gives every sign in your chart a score from 0 to 8 for each of the seven classical planets. The score is the count of contributors (out of eight: the seven planets plus the ascendant) that find the sign favourable for the planet being scored. A score of 5 or more is considered strong; 3 or fewer is considered weak. The score for one planet at one sign is the Bhinna Ashtakavarga (BAV) value. The sum of all seven planetary BAVs at one sign is the Sarva Ashtakavarga (SAV) value. Reading the score means reading both the per-planet BAV grid and the per-sign SAV grid against fixed classical bands.

What is the difference between BAV and SAV?

Bhinna Ashtakavarga is the score for one specific planet at one specific sign and ranges 0 to 8. Sarva Ashtakavarga is the sum of all seven planetary BAVs at one sign and in practice falls between 19 and 35. The full SAV grid across the 12 signs always totals 337. BAV reads the strength of one planet at one sign (used to assess that planet's transit or dasha expression). SAV reads the aggregate strength of one sign across the whole planetary system (used to assess the house that sign occupies on the chart).

Why does the chart always total 337?

Each of the seven planets has a fixed total bindu count across the 12 signs determined by the BPHS Chapter 66 contribution tables. Sun contributes 48, Moon 49, Mars 39, Mercury 54, Jupiter 56, Venus 52 and Saturn 39. These seven planetary totals sum to 337 by construction. Any chart computed correctly will produce an SAV grid that sums to 337 across the 12 signs. The per-sign mathematical average is 337 divided by 12 = 28.08 bindus, which is the chart's baseline for per-house reading. A SAV well above 28 indicates a sign that is structurally supported across the planetary system; well below 28 indicates a sign that is structurally challenged.

Who are the eight contributors that build the score?

The eight contributors are the seven classical planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn) plus the ascendant (lagna). Each planet has its own BPHS Chapter 66 contribution table that specifies which positions counted from each of the eight contributors are favourable for that planet. To compute the BAV of a sign for Jupiter you check each of the eight contributors against Jupiter's table and count the contributors that find that sign favourable. Rahu and Ketu are not contributors in the canonical eight-source method. Some traditions add them but the BPHS framework uses only the seven planets and the lagna.

What are the per-house reading bands?

Four bands are used. SAV of 30 or more reads as a strong sign: slow transits across it read constructively and the house it occupies has structural support. SAV of 28 to 29 is average and the dasha and transit overlays carry most of the reading signal. SAV of 25 to 27 is mildly weak: the house requires deliberate cultivation. SAV below 25 is the classical caution band: themes of the house tend to require sustained effort to produce outcomes that other houses produce by default. The same bands apply but the qualitative reading inverts for the dusthana houses (6th, 8th, 12th) where high SAV indicates frequent activation of difficult themes.

How does the score modulate transit and dasha readings?

The score is the chart-side filter for the universal transit and dasha calendar. When a planet transits a sign, look up that planet's BAV at that sign on this chart. BAV of 5 or more reads as a constructive transit phase across the planet's signification themes. BAV of 3 or fewer reads as a friction phase. Combine with the SAV of the sign for the broader reading and with the Vimshottari mahadasha of the relevant house lord for activation timing. The cleanest single-event signal is high BAV plus high SAV plus active dasha. The tightest caution flag is low BAV plus low SAV plus a difficult dasha. Same calendar dates, different chart-specific readings, produce the divergent outcomes.
