What is a PPF Calculator?
A Public Provident Fund (PPF) calculator is a specialized financial tool designed to help you estimate the returns on your PPF investments over its 15-year tenure. PPF is one of India's most popular long-term savings schemes, backed by the government, offering attractive interest rates and significant tax benefits.
The PPF calculator takes into account your yearly contribution amount, the current PPF interest rate, and the fixed 15-year investment horizon to project your maturity amount. It also calculates the tax benefits you can avail under Section 80C of the Income Tax Act, providing a comprehensive view of both the direct returns and tax advantages of your PPF investment.
Unlike regular savings accounts or even fixed deposits, PPF offers the unique advantage of being completely tax-free at all three stages - contribution, interest accumulation, and withdrawal (EEE - Exempt, Exempt, Exempt). This calculator helps you visualize these benefits and plan your long-term financial goals more effectively.
How to use this calculator

- 2Check the current interest rate — The calculator is pre-filled with the current PPF interest rate, but you can adjust it to see how different rates affect your returns.
- 3Select your income tax slab — Choose your applicable income tax slab to calculate the tax benefits you'll receive under Section 80C.
- 4View the results — The calculator will show your total investment, interest earned, maturity amount, and tax benefits over the 15-year period.
- 5Analyze the yearly breakdown — Check the detailed year-by-year breakdown to understand how your investment grows over time.
Formula & example
A = P × [(1 + i)^n - 1] / i
Let's calculate the maturity amount for a PPF investment with the following parameters:
- Annual contribution: ₹1,50,000 (maximum allowed)
- Interest rate: 7.1% per annum
- Tenure: 15 years (fixed for PPF)
- Tax slab: 30%
Step 1: Calculate the maturity amount
For PPF, the interest is compounded annually. However, since contributions are made throughout the year, the exact calculation is complex. A simplified approach is:
A = P × [(1 + i)^n - 1] / i
A = 1,50,000 × [(1 + 0.071)^15 - 1] / 0.071
A = 1,50,000 × [2.79 - 1] / 0.071
A = 1,50,000 × 25.21
A = ₹37,81,500
Step 2: Calculate the tax benefit
Annual tax saving = Annual contribution × Tax rate
Annual tax saving = ₹1,50,000 × 30%
Annual tax saving = ₹45,000
Total tax saving over 15 years = ₹45,000 × 15 = ₹6,75,000
Result:
- Total investment: ₹22,50,000 (₹1,50,000 × 15 years)
- Interest earned: ₹15,31,500 (₹37,81,500 - ₹22,50,000)
- Maturity amount: ₹37,81,500
- Total tax saving: ₹6,75,000
Note: The actual calculation in PPF is more complex as interest is calculated monthly based on the lowest balance between the 5th and last day of the month, and then compounded annually.

Frequently asked questions
What is a Public Provident Fund (PPF)?+
Public Provident Fund (PPF) is a government-backed long-term savings scheme that offers an attractive interest rate, complete security of investment, and tax benefits. It has a mandatory lock-in period of 15 years, though partial withdrawals are allowed from the 7th year onwards. PPF is one of the most popular tax-saving instruments under Section 80C of the Income Tax Act.
How is interest calculated on PPF?+
Interest on PPF is calculated on the lowest balance between the 5th day and the last day of each month. The interest is compounded annually and is credited to the account at the end of each financial year (March 31st). The interest rate is set by the government and is reviewed quarterly, though it typically changes annually.
What are the tax benefits of investing in PPF?+
PPF offers a triple tax benefit (EEE - Exempt, Exempt, Exempt): 1) The annual contribution up to ₹1.5 lakh qualifies for tax deduction under Section 80C, 2) The interest earned is completely tax-free, and 3) The maturity amount is also exempt from tax. This makes PPF one of the most tax-efficient investment options available in India.
What is the minimum and maximum amount I can invest in PPF?+
The minimum annual contribution to a PPF account is ₹500, while the maximum is ₹1,50,000 per financial year. You can make contributions in lump sum or in installments (up to 12) within a financial year. Any contribution exceeding ₹1,50,000 in a financial year does not earn any interest and is not eligible for tax benefits.
Can I extend my PPF account after the 15-year maturity period?+
Yes, after the initial 15-year maturity period, you can extend your PPF account in blocks of 5 years each. You have two options during extension: 1) Continue making fresh contributions (with tax benefits), or 2) Keep the corpus without making any fresh contributions but continue earning interest. This extension can be done any number of times.
When can I withdraw money from my PPF account?+
Partial withdrawals from PPF are allowed from the 7th financial year onwards. The maximum withdrawal amount is limited to either 50% of the balance at the end of the 4th year preceding the year of withdrawal or 50% of the balance at the end of the immediately preceding year, whichever is lower. Full withdrawal is allowed only after maturity (15 years).
Can I have multiple PPF accounts?+
No, an individual can have only one PPF account in their name. However, you can open another PPF account in the name of a minor child as a guardian. The combined contribution to your account and the minor's account should not exceed the annual limit of ₹1,50,000 for tax benefits.
