Why Hisab
Built for quick, honest answers
Most calculator sites bury the answer under pop-ups and sign-up walls. Hisab does the opposite: type your numbers, see the result instantly, and read a short plain-English explanation of what it means. The math uses standard published formulas, and anywhere an assumption is involved — like the PPF interest rate — it is shown and editable, not hidden.
Your numbers never leave your device. There is nothing to upload because there is no server doing the calculation — your browser does it all.
