Shadbala (sixfold strength) is a complex set of 6 distinct energy calculations in Jyotish. A good free calculator must handle , Sthana Bala (positional) , Dig Bala (directional) , Kaala Bala (temporal) , Chesta Bala (motional) , Naisargika Bala (inherent) , plus the final Shadbala总值 and Vimshopaka (average strength in shashtiamsas).
This is usually due to Ayanamsha (the precession of equinoxes). Most free calculators use Lahiri Ayanamsha (Chitrapaksha). Your astrologer might use Raman or KP Ayanamsha . Stick to one system (preferably Lahiri for Shadbala). shadbala calculator free
