How to use FD Calculator
For a cumulative fixed deposit, interest stays in the account and can earn further interest. Select the compounding frequency from your deposit terms and enter the quoted annual rate. The effective annual yield may exceed the nominal quoted rate.
This is a general compound-growth estimate, not a reproduction of any bank’s product. Actual maturity depends on deposit dates, day-count rules, interest payout options, rounding and tax deducted at source. A non-cumulative deposit with periodic interest payouts needs a different cash-flow model.
