RD Calculator
Estimate the maturity value of your monthly recurring deposit.
A Recurring Deposit (RD) lets you deposit a fixed amount every month for a set tenure and earn assured interest — ideal for disciplined, low-risk saving. This calculator estimates your RD maturity value and the interest you'll earn.
How this calculator works
Enter your monthly deposit, the interest rate, and the tenure. The calculator compounds each instalment monthly and shows your total invested, interest earned and maturity value.
The formula
M = P × ({[(1 + i)^n − 1]} / i) × (1 + i)- M
- = Maturity value
- P
- = Monthly deposit
- i
- = Monthly interest rate (annual ÷ 12 ÷ 100)
- n
- = Number of instalments (months)
Banks technically compound RD interest quarterly; this monthly annuity formula gives a very close, easy-to-understand estimate.
Worked example
You invest ₹3,00,000 and receive roughly ₹3.58 lakh at maturity — about ₹58,000 as interest.
Key benefits

- Flexible tenures and easy auto-debit
Smart tips
- Pick a tenure that matches a specific goal (e.g., a down-payment)
- Never miss instalments — banks levy small penalties
- Compare RD vs SIP: RD is guaranteed, SIP is market-linked with higher potential
- Senior citizens get slightly higher RD rates
