How to use RD Savings Estimator
A recurring deposit builds savings through repeated deposits. This tool converts your chosen compounding convention into an equivalent monthly rate, then compounds each monthly contribution. You can compare start- and end-of-month deposits.
Banks may calculate recurring-deposit interest using quarterly schedules, deposit-day rules and penalties for missed instalments. The estimate here is transparent but may not match a product’s official maturity quote. Use the bank’s terms when making a deposit decision.
The formula
A worked example
Monthly deposit (₹): 5000 · Annual rate (%): 7 · Duration (months): 36 · Compounding frequency: Quarterly · Contribution timing: Start of each month
Estimated maturity amount: ₹2,00,686.49
Uses an equivalent monthly rate from the selected compounding frequency. Actual bank RD conventions can differ.
Questions about this calculation
