The Public Provident Fund (PPF) is a government-backed savings scheme offering 7.1% annual interest, tax benefits under Section 80C, and a 15-year lock-in period. You can invest between ₹500 and ₹1.5 lakh per year, making it a popular choice for long-term, disciplined savings.
But exactly how much will your investment actually grow to?
Since PPF returns depend on annual contributions and compounding, calculating this manually is not easy.
A PPF Calculator helps you instantly estimate your maturity value, total interest earned, and overall returns, so you can plan your savings with clarity and confidence.
How Does the PPF Calculator Work?
A PPF calculator estimates the maturity value of your Public Provident Fund investment based on a few basic inputs.
You enter:
- Annual contribution amount
- Investment duration (up to 15 years)
- Applicable interest rate (as notified by the government)
Based on these details, the calculator applies the standard PPF interest calculation method, where interest is compounded annually and added to the balance at the end of each financial year.
The result shows:
- Total amount invested
- Total interest earned
- Estimated maturity value
PPF Maturity Calculation Formula
When you invest a fixed amount every year in PPF, the maturity value is calculated using the future value of a recurring investment formula:
F = P [({(1+i) ^n}-1)/i]
Where:
- F = MaF = P [({(1+i) ^n}-1)/i] ×(1+i)
Where:
- F = Maturity value
- P = Annual contribution
- i = Annual interest rate (in decimal)
- n = Number of years of contribution
Example
Assume the following:
- Annual contribution (P): ₹1,50,000
- Interest rate (i): 7.1% per annum (0.071)
- Investment period (n): 15 years
