Formula to Calculate Post Office RD Maturity Amount

If you want to calculate the P.O. RD maturity amount manually without using the Post Office RD online calculator, you can do that as well using the mathematical formula

A = P [ (1+ r/n)nt -1 ] / [ 1 - { (1 + r/n)^(-1/3) } ]


A = maturity amount,
P = installment amount,
r = RD interest rate,
n = number of times the interest rate is compounded in a year,
t = tenure in years.


For instance, if you deposit Rs. 10,000 every month for 5 years at an annual interest rate of 6.7% compounded quarterly, the maturity amount will be:

A = P [ (1+ r/n)nt -1 ] / [ 1 - { (1 + r/n)^(-1/3) } ]

A = 10000 x [{ (1 + 0.01675) ^ 20} - 1] / [1 - { (1 + 0.01675) ^(-1/3) } ]

A = ₹ 7,52,489/- (approximately)

So, the maturity value for a monthly investment of Rs. 10,000 at a 6.7% annual interest rate compounded quarterly for 5 years would be around Rs. 7,52,489.

Post Office Recurring Deposit Interest Calculation

The interest rate calculation for your Post Office RDs can be performed using either an online calculator or by manual computation. Below is the mathematical formula for this calculation.

A = P [ (1+ r/n)^nt -1 ] / [ 1 - { (1 + r/n)^(-1/3) } ]


A is the Maturity Amount
P is the monthly deposit,
r is the annual interest rate
n is number of months


If you invest in Post Office RD for ₹2,000 per month for 5 years at an annual interest rate of 6.7% compounded quarterly, the total interest earned would be:

R = ₹2,000

n = 5 years * 4 quarters/year = 20 quarters

i = 6.7 / 400 = 0.01675

Using the compound interest formula:

A = R [(1 + i)^n-1] / (1 - (1 + i)^(-1/3) )]

Calculating the value:
A = 2000 x [{ (1 + 0.01675) ^ 20} - 1] / [1 - { (1 + 0.01675) ^(-1/3) } ]
A = ₹1,42,732

Interest = Maturity Value - Total Deposits
Interest = ₹1,42,732 - (₹2,000/month * 12 months/year * 5 years)
Interest = ₹1,42,732 - 1,20,000
Interest = ₹22,732

This Post Office RD deposit would earn a total interest of ₹22,732.
