Deposits vs interest
How the pot builds
Each instalment earns for a shorter time than the one before it — the first deposit compounds for the full tenure, the last for just one month. That's why an RD earns less than an FD of the same total.

About the RD Calculator

A recurring deposit (RD) lets you deposit a fixed amount every month for a chosen tenure, earning interest at a fixed rate. It suits salaried savers who want the safety of a deposit but do not have a lump sum to lock away at once.

Each monthly instalment sits in the account for a different length of time, so each one earns a different amount of interest. This calculator adds them up precisely: for a tenure of n months, it sums P × (1 + r/400)^((n−k+1)/3) across every instalment k, using the standard quarterly-compounding convention that Indian banks apply to RDs. Summing instalment by instalment is more accurate than a single closed-form approximation.

The maturity value shown is before tax. Like FD interest, RD interest is taxable at your slab and may attract TDS. This is an estimate, and all calculation happens locally in your browser.

Examples

₹5,000/month at 7% for 60 months → deposited ₹3,00,000, maturity ≈ ₹3.58 lakh.
₹2,000/month at 6.5% for 24 months → deposited ₹48,000, maturity ≈ ₹51,300.
Raise the monthly amount to see how a small increase compounds over a long tenure.

Frequently asked questions

5 answers
How is RD interest calculated?
Banks compound RD interest quarterly. Each monthly instalment earns interest for the remaining tenure, and the maturity value is the sum of all instalments with their accrued interest.
Why not one simple formula?
A single formula is only an approximation because each instalment is invested for a different period. This tool sums each instalment individually for accuracy.
Is the interest taxable?
Yes. RD interest is taxed at your income slab, and TDS may be deducted once annual interest crosses the threshold. The figure shown is pre-tax.
Can I miss a monthly payment?
This assumes every instalment is paid on time. Missed payments usually attract a small penalty and reduce the maturity value.
How is an RD different from a SIP?
An RD gives a fixed, guaranteed return, while a SIP invests in market-linked mutual funds with variable returns. Use the SIP calculator for funds.
