Reviewed by Calculator Editorial Team

Calculate your 15-year Public Provident Fund (PPF) investment with this Post Office PPF calculator. The PPF scheme offers a guaranteed return of 7.1% per annum with tax benefits. This calculator helps you estimate your maturity amount after 15 years.

How to Use This Calculator

To calculate your 15-year PPF maturity amount:

  1. Enter your monthly investment amount in the "Monthly Investment" field.
  2. Select the tenure (15 years is fixed for PPF).
  3. Click "Calculate" to see your estimated maturity amount.
  4. Review the result and chart showing your investment growth over time.

The calculator uses the standard PPF formula with a guaranteed 7.1% annual interest rate. The interest is compounded annually.

Formula Used

The PPF maturity amount is calculated using the compound interest formula:

Maturity Amount = P × [( (1 + r/100)^n - 1 ) / (r/100)] × (1 + r/100) Where: P = Monthly investment amount r = Annual interest rate (7.1%) n = Number of years (15)

This formula accounts for the annual compounding of interest on your monthly contributions.

Worked Example

Let's calculate the maturity amount for a monthly investment of ₹1,000 over 15 years:

Maturity Amount = ₹1,000 × [( (1 + 7.1/100)^15 - 1 ) / (7.1/100)] × (1 + 7.1/100) = ₹1,000 × [(1.071^15 - 1) / 0.071] × 1.071 ≈ ₹1,000 × [2.18 - 1] / 0.071 × 1.071 ≈ ₹1,000 × 1.18 / 0.071 × 1.071 ≈ ₹1,000 × 16.6 × 1.071 ≈ ₹27,700

So, a monthly investment of ₹1,000 over 15 years would yield approximately ₹27,700 at maturity.
