Why use it

Built to be genuinely useful

Quarterly compounding

The convention Indian banks actually use — annual compounding understates the maturity figure.

Year-by-year balance

See the balance at each anniversary, exportable, rather than just the final number.

Tax reality

FD interest is taxed at your slab rate every year, not at maturity.

How it works

Three steps

  1. 1

    Enter the deposit amount and the rate your bank is offering.

  2. 2

    Set the term.

  3. 3

    Read the maturity value and the interest earned.

Quarterly compounding is not a detail

Indian banks compound fixed deposit interest quarterly by convention. A 7% FD therefore returns an effective 7.19% a year, and over a five-year term the difference against annual compounding is around ₹1,500 on a ₹1 lakh deposit.

Calculators that compound annually understate the maturity figure. Ones that let you pick without saying what your bank does are not much more useful. This one uses the quarterly convention because that is what almost every Indian bank applies.

The tax treatment is the part people miss

FD interest is taxed at your income tax slab rate, and it is taxed as it accrues each year — not when the deposit matures. For someone in the 30% bracket, a 7% FD is a 4.9% return after tax, which is often below inflation.

Banks deduct TDS at 10% once interest crosses ₹40,000 in a year (₹50,000 for senior citizens), but TDS is not the final liability. If your slab rate is higher, the balance is payable when you file.

This makes FDs a poor vehicle for long-term growth in the higher brackets, and a perfectly reasonable one for money you need in eighteen months and cannot afford to see fall.
