See your fixed deposit maturity value

Fixed deposit calculator

Calculate the maturity value and interest earned on a fixed deposit (FD) from the principal, rate, and tenure.

Formula

interest = principal × annual rate × (tenure in months ÷ 12)

Assumptions

• Uses simple interest for the full tenure, as most fixed deposit accounts pay a flat rate on the principal rather than compounding within a single term.
• Excludes withholding tax and early-withdrawal penalties, which would reduce the effective return if the deposit is broken before maturity.

Frequently asked questions

Why does this use simple interest instead of compound interest?
A single fixed deposit term pays interest on the original principal for that term, not compounding within it — compounding only happens if you reinvest the matured amount (principal + interest) into a new FD term.

What if I withdraw before maturity?
Most banks charge a penalty or pay a reduced rate for early withdrawal — this calculator assumes you hold the deposit for the full tenure entered.
