How to Use the PPF Calculator?

Formula for PPF Calculation

A PPF calculator uses a similar formula that’s used for calculating the future of an annuity. Simply put, it calculates the future value of your investment, depending on the annual contribution you make towards the PPF and the prevailing interest rate. 

The calculation formula that a PPF calculator uses is as follows:

M = P [ ( { (1 + i) ^ n } - 1 ) / i ] 

Where,

• M = Maturity benefit
• P = Annual instalments
• i = Interest rate
• n = Number of years

The part after the P in the formula is the annuity factor, which when multiplied with the annual contribution, provides the maturity value of the PPF investment. 

Example of PPF Calculation

Let’s say, If you invest ₹1,50,000 every year for 15 years:

By using this formulae “M = P [ ( { (1 + i) ^ n } - 1 ) / i ]” the calculator will automatically show

PPF Calculator Example Table

The concept of the power of compounding and how it works in favour of an investor when it comes to PPF calculation could be explained with the following table, which highlights the PPF interest earned, the principal invested and the PPF maturity value for 15, 20, and 30 year tenures.

In this PPF calculation example, it is assumed that the annual investment amount is Rs 1,50,000, and the PPF interest rate is 7.1% per annum (the current PPF interest rate is 7.1% for Q4 of FY 2024-25). 

The above example highlights the power of compounding when investing in PPF – your maturity amount rises from Rs 40 lakh to Rs 1 crore merely by investing Rs. 1.5 lakh over a 15-year period to a 30-year period.
