How the RD Calculator Works
A Recurring Deposit (RD) lets you invest a fixed amount every month for a chosen tenure, earning compound interest similar to a Fixed Deposit. Indian banks compound RD interest quarterly, and this calculator uses the standard formula published by Indian banks for RD maturity value.
where R = monthly installment, i = annual rate ÷ 400 (quarterly rate), n = number of quarters
Why Quarterly Compounding?
Unlike a Fixed Deposit where the whole amount is deposited once, an RD receives fresh money every month, each installment earning interest for a different length of time. Banks handle this by compounding quarterly on the running balance, which is what the formula above models.
RD vs. FD vs. SIP
An RD is best suited for building a savings discipline with guaranteed, bank-set returns — unlike an FD (a one-time lump sum) or a SIP into mutual funds (market-linked, with potentially higher but variable returns).
