Frequently Asked Questions
How is RD maturity value calculated?
This calculator uses the standard bank formula for recurring deposits: M = R × [(1 + i)^n − 1] ÷ (1 − (1 + i)^(−1/3)), where R is the monthly deposit, i is the quarterly interest rate, and n is the number of quarters in the tenure. This is the same formula used by most Indian banks.
Why is the interest compounded quarterly for a monthly deposit?
Most banks compound RD interest quarterly regardless of how often you deposit. Each monthly installment earns interest from the date it's deposited until maturity, and the bank formula accounts for this using quarterly compounding.
What if my tenure isn't a multiple of 3 months?
The formula still applies using a fractional number of quarters, giving a close estimate. Your bank's actual calculation for a partial final quarter may differ slightly.
Does this include TDS or tax on RD interest?
No. This calculates only the maturity value based on the deposit, rate and tenure you enter. RD interest is taxable as per your income slab, and banks may deduct TDS if interest exceeds the applicable threshold.
What's the difference between an FD and an RD?
A Fixed Deposit (FD) is a one-time lump-sum deposit that earns interest until maturity. A Recurring Deposit (RD) involves depositing a fixed amount every month, with each installment earning interest for the time it remains deposited.
Is my deposit information sent to a server?
No. All calculations happen directly in your browser. The numbers you enter are never uploaded, saved or sent anywhere.
