PPF Calculator: Calculate Public Provident Fund Maturity Amount Online
Calculate your PPF returns instantly. Enter your yearly investment, interest rate, and tenure to see how much your Public Provident Fund will grow with annual compounding.
A PPF (Public Provident Fund) calculator is a free online financial tool that helps you estimate the maturity amount and total interest earned on your PPF investment. It allows you to plan your long-term savings by showing exactly how much your annual contributions will grow over the PPF tenure with the power of compound interest.
PPF is a government-backed savings scheme in India that offers guaranteed, tax-free returns. With a lock-in period of 15 years (extendable in blocks of 5 years), it is one of the most popular long-term investment options. The PPF calculator simplifies the complex calculations involved in determining the maturity amount when you make regular yearly contributions that compound annually.
How Does a PPF Calculator Work?
The PPF calculator uses the future value of an annuity formula to compute the maturity amount based on the variables you enter. It takes three key inputs:
Yearly Investment (P) — The amount you deposit every year into your PPF account
Interest Rate (r) — The annual interest rate set by the Government of India (currently 7.1% for FY 2025-26)
Time Period (n) — The duration of your PPF investment in years (minimum 15 years)
The calculator instantly processes these inputs and displays the total amount invested, the total interest earned, and the maturity amount along with a visual donut chart showing the breakdown of investment vs. interest.
PPF Maturity Formula
Since PPF involves regular annual contributions that compound annually, the maturity amount is calculated using the future value of an annuity formula:
FV = P × [((1 + r)n - 1) / r]
Where:
FV = Future value (maturity amount)
P = Annual investment amount
r = Annual interest rate (in decimal form, e.g., 7.1% = 0.071)
n = Number of years
Example Calculation
Suppose you invest ₹1,50,000 per year at 7.1% p.a. for 15 years:
P = ₹1,50,000
r = 0.071
n = 15 years
FV = 1,50,000 × [((1 + 0.071)15 - 1) / 0.071]
FV = 1,50,000 × [((1.071)15 - 1) / 0.071]
FV = ₹40,68,209 (approximately)
Total Investment = ₹1,50,000 × 15 = ₹22,50,000
Total Interest Earned = ₹40,68,209 - ₹22,50,000 = ₹18,18,209 (approximately)
