RD Calculator — Recurring Deposit Maturity Amount
An RD (Recurring Deposit) Calculator helps you compute the exact maturity amount for your monthly recurring deposit savings. RDs are ideal for individuals who cannot invest a lump sum but want to save a fixed amount every month and earn guaranteed interest. Available at all banks and the India Post Office, RDs combine the discipline of monthly saving with the safety of fixed returns. This calculator helps you plan your RD investment, compare bank rates, and see your exact maturity amount before opening an account.
What is RD Calculator — Recurring Deposit Maturity Amount?
A Recurring Deposit (RD) is a special type of deposit offered by banks and India Post where you deposit a fixed amount every month for a predetermined tenure. At maturity, you receive the total deposited amount plus accumulated interest. Unlike FDs (which require a lump sum), RDs are designed for salaried individuals and students who can commit to a fixed monthly saving habit. Most bank RDs compound interest quarterly. Post Office RDs compound quarterly and offer government-backed safety.
Formula Used
RD maturity amount is calculated by treating each monthly deposit as a separate compound interest investment for its remaining tenure, then summing all individual maturity values. The standard quarterly compounding formula is used.
M = R × [(1 + i)ⁿ − 1] / (1 − (1 + i)^(−1/3))
Where: M = Maturity, R = Monthly Deposit, i = Quarterly Interest Rate (Annual Rate / 4 / 100), n = Number of QuartersHow to Use This Calculator — Step by Step

Real-Life Example
Ankita from Pune deposits ₹5,000 per month in an RD at 6.8% annual interest for 3 years. Total amount deposited = ₹1,80,000. Maturity amount = ₹1,97,452. Interest earned = ₹17,452. If she opens the same RD at the Post Office (currently 6.7%), maturity = ₹1,96,956. The bank RD is marginally better in this case. The key takeaway: even modest monthly savings build significant corpus over time.
