Shadbala Calculator
Strength is measured in shashtiamsas; sixty of them make one rupa. Low strength does not mean a “bad planet” — only that the planet takes longer to deliver what it signifies.
What this calculator tells you
This computes Shadbala for each planet — turning “this planet is strong” from an impression into a number. Five principal planets, with their total strength broken into its parts.
How the calculation works
Shadbala means six kinds of strength. The calculation follows the BPHS method and results are given in virupas — 60 virupas = 1 rupa. The six components are Sthana (positional), Dig (directional), Kaala (temporal), Cheshta (motional), Naisargika (natural) and Drik (aspectual). Their sum is the total strength.
How to read the result
Reading only the total is incomplete — the breakdown is where the value is. A planet can be strong in Sthana bala and weak in Cheshta bala, and that means something quite different. One caveat stated plainly: texts and software differ by a few virupas on some of these components. That is normal, not an error.
Common questions
What counts as good strength?
The tradition sets a different minimum for each planet, so no single figure applies across the board — the page gives each planet’s components separately.
How does Shadbala differ from Ashtakavarga?
Shadbala measures a planet’s own strength. Ashtakavarga assigns bindus to signs. One asks about the planet, the other about the territory.
Why do other sites give different numbers?
Because the texts do not fully agree on how some sub-strengths are computed. A few virupas of difference is common — only a large gap is worth questioning.
