Formula & Mathematical Methodology: Quarterly Compounded FD & RD Maturity Formula
- P: Deposit principal
- r: Annual nominal interest rate (decimal)
- t: Tenure in years (Months ÷ 12)
Rounding: Rounded to 2 decimal places.
Compute bank FD (lump-sum) and RD (monthly installment) maturity values using quarterly IBA compounding conventions.
Rounding: Rounded to 2 decimal places.
A saver places ₹2,00,000 in a 3-year cumulative bank FD at 7.25% compounded quarterly (12 quarters).
Because interest is credited every quarter and earns interest in subsequent quarters. A 7.25% rate compounded quarterly yields an effective annual return of 7.45%.
Switch seamlessly between Fixed Deposit (lump sum) and Recurring Deposit (monthly savings) modes with configurable quarterly, monthly, or annual compounding. Whether you are researching fixed deposit calculator, recurring deposit calculator, bank fd maturity, rd maturity calculator, cd calculator, this interactive tool helps you calculate maturity amount, total interest earned, and effective annual yield for Bank Fixed Deposits (FD) and Recurring Deposits (RD).
As you adjust Deposit Scheme Type, Deposit Amount (Lump Sum or Monthly), Nominal Annual Interest Rate, Deposit Tenure (Months), the calculator immediately computes Maturity Value (₹), Total Principal Deposited (₹), Total Interest Earned (₹), Effective Annual Yield (%) and updates all three domain-specific SVG charts in real time. Instead of relying on a single static figure, you can inspect the primary domain diagram, component breakdown, and multi-point trajectory curve to see how changing your inputs shifts the final result. Use the Compare (up to 3 scenarios) button to evaluate side-by-side variations before making a decision.
In our benchmark scenario (₹2,00,000 Fixed Deposit at 7.25% p.a. for 36 Months (Quarterly Compounding)), Maturity value is ₹2,48,109.40 with ₹48,109.40 in interest. Keep in mind that cumulative reinvestment option where interest remains in the deposit until maturity.
