RD Calculator
Calculate the maturity value of a bank or post office recurring deposit with quarterly compounding.
RD maturity formula
A recurring deposit takes a fixed amount every month. Most Indian banks compound RD interest quarterly, so each instalment grows for the months it stays deposited: Maturity = Σ R × (1 + r/4)4 × m/12, where m is the number of months that instalment remains invested.
Example
₹5,000 a month for 5 years at 6.8% matures at about ₹3.58 lakh on ₹3 lakh deposited.
RD vs SIP
An RD gives a fixed, known return and is suitable for short-term goals. A SIP in equity funds can earn more over long periods but with no guarantee. RD interest is taxable at your slab rate, and banks may deduct TDS.
