Deposit calculator

Fixed deposit (FD) calculator

Work out the maturity amount of a cumulative FD for any compounding frequency, or the regular interest you would receive if the interest is paid out. Uses the quarterly compounding and broken-period method that SBI publishes for its term deposits.

Use your bank's current card rate for your tenure. 7% is only an example.

How FD interest is calculated

For a reinvestment (cumulative) deposit, interest is added to the deposit at the end of each compounding period and then earns interest itself. SBI, for example, states that for completed quarters interest is compounded quarterly, and that for the broken period left over after the last completed quarter, interest is calculated on the basis of a 365-day year. For deposits where interest is paid out monthly, quarterly or half-yearly, SBI pays it without compounding (Source: State Bank of India, checked 26 October 2026).

A = P × (1 + R/k)q × (1 + R × m/12)

  • k = compounding periods per year (4 for quarterly).
  • q = number of completed periods.
  • m = months left over after the last completed period, which earn simple interest. Banks count the actual days; this calculator uses months, so a bank's figure can differ by a little.

The effective yearly yield converts the result into a once-a-year rate so you can compare options: quarterly compounding at 7% works out to about 7.19% a year.

For the pay-out option, each payout is P × R ÷ (payouts per year), and the deposit itself is returned at maturity.

Worked examples

  1. ₹1,00,000 for 1 year at an example 7%, compounded quarterly: quarterly rate = 7 ÷ 4 = 1.75%; four quarters: 1,00,000 × 1.01754 = ₹1,07,185.90, so interest is ₹7,185.90.
  2. The same deposit for 14 months: 4 completed quarters, then 2 months at simple interest: 1,07,185.90 × (1 + 0.07 × 2 ÷ 12) = ₹1,08,436.41.
  3. ₹5,00,000 for 3 years at 7% with quarterly payouts: each payout is 5,00,000 × 0.07 ÷ 4 = ₹8,750; 12 payouts total ₹1,05,000, and the ₹5,00,000 is returned at maturity.

Good to know

  • Deposit insurance: DICGC insures each depositor in a bank up to ₹5,00,000 for principal and interest combined, and the limit applies separately to deposits in each bank (Source: Deposit Insurance and Credit Guarantee Corporation, checked 26 October 2026).
  • Results are before any tax or tax deducted at source. Premature withdrawal is governed by the bank's own terms, which can mean a lower rate and a penalty.
  • Rates differ by bank, tenure and depositor category and change from time to time; always use the rate your bank quotes on the day you deposit.
