About this Tool

A Fixed Deposit locks a lump sum with a bank for a fixed tenure at a guaranteed rate, compounded quarterly. This calculator estimates the maturity value and interest earned so you can compare tenures and rates before booking a deposit.

Common Use Cases

Compare Tenures

See how 1, 3 and 5-year deposits differ before locking in your money.

Rate Shopping

Compare bank offers side by side — small rate gaps compound into real money.

Emergency Fund Parking

Estimate returns on idle cash parked in short-term FDs or sweep-ins.

Senior Citizen Benefits

Factor in the extra 0.25–0.50% banks pay seniors by entering the higher rate.

Pro Tips

  • !

    Ladder Maturities

    Split deposits across tenures so some money frees up every year without breaking FDs.

  • !

    Mind Premature Penalties

    Breaking an FD early usually costs ~1% — keep emergency cash in savings instead.

  • !

    Check Tax Impact

    FD interest is taxable; post-tax returns matter more than headline rates.
