How to use the Recurring Deposit (RD) Calculator
A recurring deposit (RD) builds a maturity estimate from equal periodic deposits rather than one starting lump sum. Each instalment earns interest for a different length of time, so the result is not the same as compounding the total contributions for the full term.
Banks can use quarterly compounding, exact instalment dates, penalties for missed deposits, and institution-specific rounding. Use the estimate to plan contribution affordability and confirm final figures with the deposit terms.
Step-by-step
- Enter the monthly instalment you can maintain for the full term.
- Use the rate and tenure stated in the RD product information.
- Calculate total contributions, projected interest, and maturity value.
- Stress-test the monthly commitment before opening the deposit, especially if income is variable.
How to read the result
- Total deposited is the monthly instalment multiplied by the number of deposits.
- Projected interest reflects the shorter earning period of later instalments.
- Maturity value combines all contributions and estimated interest before tax or penalties.
Common mistakes to avoid
- Treating every instalment as invested from day one.
- Ignoring missed-instalment or premature-closure rules.
- Comparing the maturity value without comparing total contributions and liquidity.

More questions about Recurring Deposit (RD) Calculator
Why does an RD earn less than an equal lump-sum FD?
Most RD money arrives gradually, so later instalments have less time to earn interest.
Does the estimate include missed-payment penalties?
No. It assumes each scheduled contribution is made as planned.
Can rates change during the RD?
Product terms determine whether the booked rate is fixed; confirm this directly with the institution.
