FD Calculator

What is a fixed deposit?

A fixed deposit (FD) is a lump sum deposited with a bank or post office for a fixed tenure at a fixed interest rate. The rate is locked in for the whole tenure regardless of what happens to market rates afterward, and interest compounds at regular intervals until maturity.

Worked Example — ₹1,00,000 for 5 years at 7% (quarterly)

Common Mistakes to Avoid

• This is a cumulative FD, not a monthly-payout FD. It assumes interest reinvests and compounds until maturity — a non-cumulative FD that pays interest out monthly instead works differently and won't match this maturity figure.
• FD interest is taxable. Interest earned is added to your income and taxed at your slab rate — this calculator shows the pre-tax maturity value, not what you'll actually keep after tax.
• Quarterly is the most common default, but not universal. Confirm your bank's actual compounding frequency rather than assuming — monthly, quarterly, half-yearly, and yearly are all real options banks use.
