PPF Calculator
Estimate PPF maturity value from yearly contributions (India only)
What is the PPF Calculator?
The PPF Calculator estimates the maturity value of a Public Provident Fund account based on your yearly contribution, the current interest rate, and the investment period. This calculator is based on India's Public Provident Fund scheme, a government-backed savings product, and is not applicable outside India — there is no direct US, UK, Canadian or Australian equivalent with the same rules or tax treatment.
How to Use the PPF Calculator
- Enter your yearly investment — the total amount you plan to deposit into the PPF account each year (minimum ₹500, maximum ₹1,50,000 per the scheme's rules).
- Set the investment period — the standard lock-in is 15 years, extendable in blocks of 5 years.
- Check the interest rate — pre-filled with the current government-notified rate, but adjust it if the rate has since changed.
- Read the result — total amount invested, interest earned, and the projected maturity amount.
PPF Maturity Formula
PPF interest is compounded annually. Each year, the yearly contribution is added to the running balance, and the whole balance then earns interest for the year:
This is repeated for each year of the investment period to arrive at the final maturity amount.
Example Calculation
Investing ₹1,00,000 every year for the full 15-year term at 7.1% annual interest builds up to a maturity amount of approximately ₹27,12,139 — total contributions of ₹15,00,000 plus roughly ₹12,12,139 in tax-free interest.
