The PPF post office calculator estimates the maturity value for a given amount invested in PPF.

How Does Post Office PPF Calculator Work?

You can follow the easy steps mentioned below to use the PPF calculator and calculate expected returns from post office PPF investments accurately:

Formula For Post Office PPF Calculator

The Post Office PPF Returns can be calculated using the following formula:

M = P [({(1+ i) ^ n} – 1) / i]

Where,

  • M = Total maturity value by the end of the investment period
  • P = Amount of money contributed annually to the PPF account
  • i = PPF interest rate in post office
  • n = Total number of years until maturity

Example For Post Office PPF Calculation

Let us assume you invest Rs 1.5 lakh a year at a 7.1% interest rate. Given below is the detailed calculation for the same: 

Initial Investment: 15 Years

  • Annual Investment = ₹1,50,000
  • Interest Rate = 7.1% (compounded annually)
  • Duration = 15 years

Total Contribution = ₹1,50,000 × 15 = ₹22,50,000
Interest Earned = ₹18,18,209
Maturity Amount = ₹22,50,000 + ₹18,18,209 = ₹40,68,209

First Extension: 5 Years

  • Additional Contribution = ₹1,50,000 × 5 = ₹7,50,000
    Total Investment So Far = ₹22,50,000 + ₹7,50,000 = ₹30,00,000
    Interest Earned = ₹36,58,288 (total including past and new)
    Maturity Amount = ₹30,00,000 + ₹36,58,288 = ₹66,58,288

Second Extension: Another 5 Years 

Additional Contribution = ₹1,50,000 × 5 = ₹7,50,000
Total Contribution Over 25 Years = ₹30,00,000 + ₹7,50,000 = ₹37,50,000
Interest Earned = ₹65,58,015 (total including past and new)
Final Corpus = ₹37,50,000 + ₹65,58,015 = ₹1,03,08,015
