Planet Strength & Dosha Tools
A planet's sign placement is a starting point, not a conclusion. Vedic astrology developed two rigorous quantitative systems — Shadbala and Ashtakavarga — to measure how much functional power a planet actually has. These sit alongside the dosha checkers: Mangal Dosha (classical, with extensive cancellations), Kala Sarpa (late-traditional, with important historical context), and the dignity and Avastha table that shows each planet's comfort level in your chart.
The Tools
Five calculators using classical algorithms from BPHS and the Phaladeepika.
Shadbala Calculator
Computes all six strength components for each planet in Virupas: Sthana (positional), Dig (directional), Kala (temporal), Chesta (motional), Naisargika (natural fixed-order), and Drik (aspectual). Total divided by 60 gives the Rupa score.
From BPHS Chapters 27–39
Ashtakavarga Points
Calculates Bhinnashtakavarga (0–8 bindus per sign, per planet) and Sarvashtakavarga (sum of all 7 planets per sign). A chart always distributes exactly 337 bindus total across 12 signs. SAV above 30 per house is the classical strength threshold.
337 total bindus · SAV 30+ = strong
Mangal Dosha Checker
Screens Mars from Lagna, Moon, and Venus. Returns a Poorna (full) diagnosis only when dosha appears from two or more reference points. Runs the full classical cancellation list — own sign, exaltation, debilitation, Jupiter aspect, mutual Manglik, and ascendant-specific exceptions.
Three reference points · full cancellation rules
Planetary Dignity Table
Ranks each planet's sign placement: exalted, moolatrikona, own sign, friend's sign, neutral sign, enemy sign, or debilitated. Also calculates Avastha — the age-state of each planet (Bala/infant through Mrita/dead) based on degree position.
Exaltation → Debilitation · Avastha states
Kala Sarpa Configuration
Checks whether all seven classical planets (Sun–Saturn) are hemmed on one side of the Rahu–Ketu axis — degree-level, not just sign-level. Identifies the type (Anant through Sheshnag) and direction (Savya ascending or Apasavya descending).
12 types by Rahu house · Savya / Apasavya
Shadbala — Six Sources of Strength
Defined in BPHS Chapters 27–39. All six components are measured in Virupas (1 Rupa = 60 Virupas). The total Shadbala is compared against each planet's minimum required Rupa to determine whether it is functionally strong or weak.
Sthana Bala
Positional
Sign placement — exaltation gives maximum; debilitation subtracts. Five sub-components including Uchcha Bala (degree proximity to exaltation point) and Saptavarga Bala (strength across seven divisional charts).
Dig Bala
Directional
House placement relative to a planet's directional stronghold. Sun & Mars peak in the 10th, Jupiter & Mercury in the 1st, Moon & Venus in the 4th, Saturn in the 7th. Maximum 60 Virupas at the stronghold, 0 at the opposite house.
Kala Bala
Temporal
Six time-based sub-factors: day vs night birth, lunar paksha (waxing/waning Moon), hora ruler, weekday ruler, month lord, and year lord. Most complex component to compute.
Chesta Bala
Motional
A planet's apparent motion — retrograde, stationary, fast, or slow. Retrograde planets score high here, which is why a retrograde Saturn in a difficult sign can still be functionally powerful.
Naisargika Bala
Natural (fixed)
The only chart-independent component. Fixed ranking: Sun > Moon > Venus > Jupiter > Mercury > Mars > Saturn. Tells you inherent expressive capacity regardless of placement.
Drik Bala
Aspectual
Net of aspects received. Benefic aspects (Jupiter, Venus) add Virupas; malefic aspects (Sun, Mars, Saturn) subtract. The only Shadbala component that can go negative, dragging the total down.
Key insight: Naisargika Bala is the only fixed component — Sun is always strongest, Saturn always weakest, regardless of chart. Drik Bala is the only component that can go negative, meaning malefic aspects from Saturn, Mars, and the Sun can actively reduce a planet's total Shadbala below what its placement alone would suggest.
Ashtakavarga — 337 Bindus for Transit Prediction
Every chart distributes exactly 337 bindus across 12 signs. The Bhinnashtakavarga (BAV) gives each planet a score of 0–8 per sign. The Sarvashtakavarga (SAV) sums all seven planets per sign. Both layers are needed for transit prediction.
BAV 5–8
Favorable transit
BAV 4
Mixed results
BAV 0–3
Challenging transit
SAV 30+
Strong house overall
The most meaningful transit signal: a slow planet (Saturn at 2.5 years per sign, Jupiter at 13 months) entering a sign where its own BAV is 6–8 and the SAV is 32+, during that planet's own Mahadasha or Antardasha. The opposing combination — BAV 1–2, SAV below 25, difficult Dasha — is the strongest classical caution flag in the system.
