Deposit rates are quoted by banks and issuers as nominal annual rates. CompoundX does not show live rates — enter the rate offered to you.
Interest compounds at the chosen frequency for every whole period. Any leftover months and days earn simple interest on the compounded balance. Deposits shorter than six months earn simple interest, as is common bank practice.
A = P × (1 + r/m)^K × (1 + r × f)
Interest is paid out each period and not reinvested. Many banks pay monthly interest as the discounted equivalent of quarterly compounding — switch it on to see that convention.
payout = P × r ÷ payouts per year
For cumulative deposits, the annualised growth over the tenure. For payout deposits, the average simple yield, because payouts are not reinvested. Tax (including TDS) and premature-withdrawal penalties are not included.
effective yield = (A ÷ P)^(1/t) − 1
Default assumptions are hypothetical round numbers chosen for illustration. They are not forecasts and not a view on any product. Change them to see how sensitive the result is.
