🔁 RD Calculator (Recurring Deposit)

About this RD Calculator (Recurring Deposit)

A recurring deposit (RD) builds a lump sum from equal monthly deposits, with interest compounded quarterly the way banks do it — each installment is added monthly and interest is applied to the growing balance every quarter. This calculator follows that same month-by-month method, giving a close approximation of the maturity value a bank would pay.

How to use it

1. Enter the amount you will deposit every month.
2. Enter the yearly interest rate offered on the RD.
3. Enter the period in years.
4. Click Calculate maturity to see the maturity value, total deposited and interest earned.

Example

Depositing 10,000 a month for 3 years at 11% builds deposits of 360,000 and matures at roughly 420,000 — around 60,000 of interest, depending on the exact bank method.

Frequently asked questions

Why is the RD result approximate?

Banks compound on exact calendar quarters and count days for part-quarters, while this calculator compounds every third monthly installment. The difference is small — usually well under 1% of the maturity value.

Is an RD better than an FD?

They suit different savers: an FD needs a lump sum today, an RD builds the sum from monthly income. Rates are usually similar; the best choice is the one you will actually keep up.
