RD Calculator

How the RD calculator works

A recurring deposit (RD) lets you set aside a fixed amount every month with your bank or post office for a chosen tenure, earning a guaranteed interest rate. It's a disciplined way to save from monthly income towards a goal — a gadget, a trip, an emergency fund — without needing a lump sum upfront the way a fixed deposit does.

By RBI convention, RD interest is compounded quarterly. This calculator reproduces that exactly: it converts the annual rate into an equivalent monthly rate, (1 + r/400)^1/3 − 1, then adds each monthly deposit at the start of the month and grows the whole balance. Because every instalment keeps earning interest for the rest of the tenure, your earliest deposits contribute the most to the final corpus. The maturity value shown is before tax — RD interest is taxable at your slab rate, and banks deduct TDS once your interest crosses the annual threshold.
