Calculation methodology
The estimate uses the standard Post Office RD-style quarterly-compounding maturity formula for equal monthly instalments. It does not model missed deposits, default charges, advance-deposit rebates or premature closure.
Important assumptions
- Results are estimates based on the values you enter.
- Rates and returns are assumed for the projection period and may change in real life.
- Taxes, fees, market conditions and provider-specific rules may affect actual outcomes.

The default rate reflects the current Q3 FY 2026-27 small-savings rate, but the rate is editable. The estimate uses equal monthly instalments and the standard quarterly-compounding RD formula; account defaults, rebates and premature closure are not modeled.

RD Calculator Guide
What Is a Recurring Deposit (RD) Calculator?
A recurring deposit calculator estimates how regular monthly savings may grow over a chosen tenure. Enter the amount you plan to deposit each month, an annual interest-rate assumption, the number of months and a compounding frequency to see total deposits, estimated interest and maturity value.
An RD differs from a fixed deposit because the money is added over time instead of being invested as one lump sum at the start. The result is a planning estimate, not a provider quote.
How to Use the RD Calculator
Enter the monthly instalment you can save, the annual interest rate quoted or assumed for your scenario, and the tenure in months. Choose a compounding frequency for the model, then review the maturity value, total deposited and estimated interest.
Try more than one tenure or rate to see how the assumptions affect the outcome. For a real account, match the calculator settings to the provider's deposit schedule and terms as closely as possible.
How Is RD Interest Estimated?
The calculator adds each monthly deposit to the running balance and applies the selected compounding assumption as the projection advances. It reports maturity value as the projected balance, total deposited as the monthly deposit multiplied by the number of months, and estimated interest as maturity value minus total deposits.
The model uses the compounding frequency you select and does not reproduce every institution's exact day-count, deposit-date or rounding rules. A bank or post-office quote may therefore differ, even when the displayed annual rate is the same.
Worked RD Example: 1,000 per Month for 12 Months
Suppose you deposit 1,000 currency units each month for 12 months and enter an assumed annual rate of 6% with quarterly compounding. Total deposits are 12,000 currency units. Using this calculator's monthly-step projection, the estimated maturity value is about 12,395 currency units and estimated interest is about 395 currency units.
This example is illustrative rather than a fixed maturity quote. Change the rate and compounding frequency above to see how the estimate changes, and confirm the provider's exact maturity calculation before opening an account.
RD vs FD: Which Cash-Flow Pattern Fits?
An RD is designed for regular contributions, while an FD typically starts with a one-time deposit. An RD can suit a savings plan funded from monthly income; an FD models money available to deposit at the beginning. Their results are not directly comparable unless you account for when and how much money is contributed.
Use the FD Calculator to model a one-time deposit. Compare the rate, tenure, liquidity, early-closure conditions and total amount contributed rather than looking only at the final balance.
What This RD Estimate Does Not Include
The calculator assumes equal monthly deposits and does not model missed instalments, default charges, advance-deposit rebates, premature closure, provider-specific penalties or tax. The selected rate is an input, not a live feed of current offers.
Before relying on a result, check the current scheme or account rules for eligible tenure, deposit dates, rate, maturity, closure and tax treatment. Actual terms can differ by institution and jurisdiction.
This is an estimate, not a bank or post-office quote. The calculator does not model missed instalments, early closure, penalties or tax.
How does an RD calculator work?
Enter a monthly deposit, annual interest-rate assumption, tenure in months and compounding frequency. The calculator estimates total deposits, interest and maturity value using those inputs.
How much will I get if I deposit 1,000 every month for a year?
The maturity value depends on the annual rate and compounding method. Enter 1,000 as the monthly deposit and 12 months as the tenure, then compare the projected maturity value with total deposits. The result is an illustration, not a provider quote.
Does a longer RD tenure always earn more interest?
A longer tenure usually gives deposits more time to earn interest, but the total interest also depends on the monthly amount, rate, compounding method and any provider-specific rules. Compare the same monthly contribution across different tenures.
Does this calculator include missed instalments or penalties?
No. It assumes equal monthly deposits and does not model missed instalments, default fees, advance-deposit rebates or account-specific adjustments.
Is RD interest taxable?
Tax treatment depends on your jurisdiction and circumstances. This calculator estimates deposit growth only and does not calculate tax, withholding or any applicable deduction.
How is recurring deposit interest calculated?
The estimate adds each monthly deposit and applies the selected compounding assumption through the remaining projection. Real providers may use a specific deposit date, day-count convention and scheme formula, so their quoted maturity amount can differ.
What is the difference between an RD and an FD?
An RD builds a deposit through regular contributions, commonly monthly. An FD generally starts with a one-time principal. Because the timing of deposits differs, compare the total amount contributed, tenure, interest terms and liquidity conditions.
Can I change the RD interest rate or compounding frequency?
Yes. These are editable assumptions in the calculator. Use the rate and frequency that match the product you are researching; the available choices are mathematical settings and may not match every provider's terms.
Can I withdraw an RD before maturity?
Premature closure depends on the provider and account rules and may reduce interest or trigger a penalty. This calculator does not model early closure, so check the current scheme terms before relying on the estimate.
Is the maturity amount guaranteed?
No. This is a mathematical estimate based on the inputs you enter, not a bank or post-office quote. Verify the applicable rate, deposit dates, maturity rules, penalties and tax treatment with the provider.
