FD calculator — maturity + compounding bonus.
Shows not just the maturity value, but how much of your gain is simple interest vs the compounding bonus — the part that makes FDs better than a linear interest return. Four compounding options (quarterly is the Indian-bank default).
Your FD
Most Indian banks use quarterly compounding by default.

₹5,00,000 at 7.0% for 5 years grows to ₹7.07 L. Simple-interest on the same inputs would be ₹6.75 L — the extra ₹32,389 comes from compounding.
FD interest is fully taxable at slab rate. Banks deduct 10% TDS once annual interest crosses ₹40,000 (₹50,000 for seniors) — adjust in ITR. Submit Form 15G/15H if total income is below the taxable threshold to avoid TDS deduction.
Compounding formula
M = P × (1 + r/f)^(f·t) P = principal r = annual rate (decimal) f = compoundings per year (quarterly=4, monthly=12) t = years
FD tax (FY26)

- Submit Form 15G/15H if total taxable income is below the basic exemption — stops TDS at source.
