About RD Calculator
Calculate Recurring Deposit (RD) maturity amount with quarterly compounding as per Indian banking practice. Shows total interest earned and effective annual yield. Compare returns across SBI, HDFC, ICICI, and Post Office RD rates.
A Recurring Deposit lets you invest a fixed amount every month for a chosen tenure, functioning as a disciplined middle ground between a savings account and a lump-sum Fixed Deposit — useful for building toward a specific goal with a predictable monthly outflow rather than requiring a large sum upfront. Indian banks compound RD interest quarterly, following the same convention as fixed deposits, which makes the maturity calculation slightly more involved than simple interest since each quarter's compounding applies to a growing principal as new monthly deposits are added. This calculator applies the actual quarterly-compounding formula used by Indian banks to project your exact maturity amount based on monthly deposit, interest rate, and tenure.
