How the RD calculator works
Enter your monthly deposit, the interest rate, and the tenure in months. Each instalment is compounded quarterly for the months it stays invested, and the calculator totals them into your maturity value.
What this RD scenario includes
The model totals equal monthly deposits under its disclosed fractional-quarter convention. It does not compare product risk, fees, tax, penalties, liquidity, or suitability.

Formula: Maturity = Σ monthlyDeposit × (1 + annualRatePercent / 400)^((monthsRemaining) / 3)
Educational boundary: Deposit arithmetic only; it is not a bank quote or product recommendation.
Included: Equal monthly deposits; Existing fractional-quarter compatibility convention
Excluded: Bank-specific instalment timing, day count, compounding, fees or rate changes; Taxation, penalties or product suitability
Inputs: monthlyDeposit (INR; 500–500000; default 10000, existing public route default) · annualRatePercent (percent per year; 1–12; default 7, existing public route default) · months (whole months; 6–120; default 60, existing public route default)
Outputs: invested (INR; raw calculation; displayed rounded to nearest rupee) · interest (INR; raw calculation; displayed rounded to nearest rupee) · maturityValue (INR; raw calculation; displayed rounded to nearest rupee)
Assumptions: Deposits are made monthly. The existing route's quarterly rate with fractional-quarter accrual is retained for compatibility.

Frequently Asked Questions
What is a recurring deposit?
A recurring deposit is a contractual product with periodic deposits. This calculator only illustrates one rate convention; it does not assess an institution, deposit safety, liquidity, tax or suitability.
How is RD maturity calculated?
Each monthly instalment earns interest for the remaining months, compounded quarterly. Earlier instalments earn more because they stay invested longer. This calculator sums the compounded value of every instalment.
Is RD interest taxable?
Tax and TDS are excluded. Verify the rules, thresholds and treatment for the relevant tax year and your circumstances.
Does this compare an RD with a SIP?
No. They have different contractual, market, liquidity, tax, fee and loss characteristics. This page calculates only the entered RD scenario and does not choose a product.
