Savings • Monthly deposit estimate
Recurring Deposit Calculator
Estimate how fixed monthly deposits may grow over a chosen tenure. The tool shows deposits, estimated interest and maturity using one transparent monthly-growth convention.
Enter RD details
Use the rate shown in the bank's current deposit terms.
How to use this RD calculator
- Enter the monthly amount you can deposit consistently.
- Add the annual rate shown by the bank.
- Enter the tenure in complete months.
- Review total deposits, interest and estimated maturity.
- Compare a second monthly amount before opening the RD.
Formula and assumptions
M = D × [((1 + i)n − 1) ÷ i] × (1 + i)
D is the monthly deposit, i is annual rate divided by 12 and 100, and n is the number of months. At 0%, maturity is D × n. The model assumes each deposit occurs at the beginning of a month. Currency results are rounded to the nearest rupee.
Worked Indian example
Suppose Neha deposits ₹5,000 every month for 36 months using an illustrative 7% annual rate. The model estimates:
| Total deposited | ₹1,80,000 |
|---|---|
| Estimated interest | ₹20,815 |
| Estimated maturity | ₹2,00,815 |
This is not a quote. The bank may calculate interest using different eligible dates, compounding intervals or rounding rules.
How to interpret the result
Total deposited is the amount you contribute. Estimated interest is the difference between maturity and deposits. Use maturity to check whether the RD supports a near-term goal, but also compare liquidity and premature-closure rules.
Common mistakes
- Using an advertised rate without checking the exact tenure.
- Ignoring missed-installment or closure conditions.
- Committing emergency cash to a less flexible product.
- Comparing RD maturity directly with a market-linked SIP forecast.
Practical tips
- Choose a deposit that fits even in expensive months.
- Align the maturity date with the goal date.
- Keep a separate emergency reserve.
- Read nomination, renewal and premature-closure terms.
- Compare post-tax outcomes where relevant.
