What is a PPF calculator? 

A PPF calculator is a simple online tool that helps investors calculate the amount they will receive at the time of maturity, which usually happens at the end of 15 years of investing. The tool also allows you to calculate the amount you need to invest either as lump-sum or as periodic contributions to PPF to meet your target corpus at the time of retirement or to realise any other financial goal. 

Formula used for calculating PPF

A PPF calculator uses a simple formula to determine the maturity amount. Here’s the formula for calculating PPF when you want to invest just once in PPF: 

A = P * [(1 + r/n) ^ (n*t) - 1]


  • A is the maturity amount
  • P is the principal amount
  • r is the annual interest rate
  • n is the number of times interest is compounded per year
  • t is the number of years

Please note that the interest rate on PPF keeps changing and is dependent on macroeconomic situations.
