How the Post Office RD Calculator Works

The RD calculator post office uses a formula that accounts for quarterly interest compounding to calculate the maturity amount accurately.
Example Calculation
Suppose you invest ₹2,000 every month for 5 years (60 months) at an annual interest rate of 6.70%.
-
Quarterly rate, i = 6.7 ÷ 4 ÷ 100 = 0.01675
-
Total quarters, n = 60 ÷ 3 = 20
Plug these into the formula:
M = 2,000×(1+0.01675)20−11−(1+0.01675)−1/3
M = 2,000{(1 + 0.01675)^{20} - 1}{1 - (1 + 0.01675)^{-1/3}}
M = 2,000×1−(1+0.01675)−1/3(1+0.01675)20−1
The result is roughly around ₹1,39,000, which includes your total deposits plus the interest earned.
Factors Affecting Post Office Recurring Deposit Returns
Several key factors determine the final maturity amount of a Post Office Recurring Deposit, and the Post Office Recurring Deposit Calculator can help investors understand how each of these factors affects their returns:

Monthly Deposit Amount: Higher monthly contributions lead to a larger maturity amount over time.
-
Interest Rate: Post Office RD interest rates are revised quarterly, so always use the latest applicable rate when estimating returns.
-
Investment Tenure: A longer tenure allows more compounding cycles, which increases total returns.
-
Compounding Frequency: Interest is compounded quarterly, adding to the final maturity value.
-
Missed Payments: Skipping or delaying deposits can lower overall earnings and may attract penalties.
-
Premature Withdrawal: Premature closure of a Post Office RD is allowed only after 3 years, and no closure is permitted until any advance-deposit period is completed.
