How this Post Office RD calculator works
The Post Office Recurring Deposit (officially the National Savings Recurring Deposit Account) lets you deposit a fixed amount every month for 5 years and earn 6.7% per annum, compounded quarterly. Enter your monthly deposit above and the calculator instantly shows the maturity value, the total you will deposit over 60 months, and the interest you earn on top. The chart and table break the growth down year by year so you can see how compounding accelerates in the later years.
The minimum deposit is ₹100 per month, in multiples of ₹10, and there is no upper limit. The tenure is fixed at 5 years (60 monthly deposits); after maturity you can extend the account for another 5 years at the post office.
The RD maturity formula in plain language
India Post compounds RD interest every quarter while you deposit every month. The official maturity formula is:
M = R x [(1 + i)n - 1] / (1 - (1 + i)-1/3)
Here R is your monthly deposit, i is the quarterly interest rate (the annual rate divided by 4, so 6.7% becomes 1.6750% per quarter as a fraction) and n is the number of quarters, which is 20 for the standard 5-year term. In simple terms: each deposit earns interest for the quarters it stays in the account, and the interest itself earns interest every quarter after that.
Worked example: ₹5,000 per month
Suppose you deposit ₹5,000 every month for 5 years at 6.7%. Over 60 months you deposit ₹3,00,000. Applying the formula with i = 6.7% / 4 and n = 20 quarters gives a maturity value of ₹3,56,829, which means ₹56,829 of interest. The same maths at ₹100 per month produces ₹7,137, the figure you will see quoted as the standard example for the scheme.
