The PPF Calculator shows how much your Public Provident Fund investment will grow. Enter how much you deposit each year, the interest rate, and how long you stay invested, and it instantly calculates your total deposits, the interest earned, and the final maturity amount — with a clear breakdown of how much of your corpus comes from your own money versus interest.
PPF is one of India’s most popular long-term savings schemes because it is government-backed, offers tax-free returns, and qualifies for a deduction under Section 80C. This calculator runs entirely in your browser, so none of your figures are uploaded or stored.
How to use the PPF calculator
- Enter the amount you plan to deposit each year (up to the ₹1.5 lakh annual limit).
- Set the interest rate — the current PPF rate is 7.1% per annum, revised quarterly by the government.
- Choose your tenure — PPF has a 15-year lock-in, extendable in blocks of 5 years.
- Read the maturity value, total interest, and invested amount, updated live as you adjust the sliders.
How PPF interest is calculated
PPF interest is compounded annually. Interest for each month is calculated on the lowest balance between the 5th and the last day of the month, so depositing before the 5th of the month earns you interest for that month. This calculator assumes your yearly deposit is made at the start of the year and interest is credited at year end, which matches the way most PPF maturity estimates are shown.
Because the returns compound every year for at least 15 years, a large share of your final corpus comes from interest rather than your own deposits — which is why starting early and depositing the full limit makes such a big difference.
Why PPF is popular
- Government-backed, so the capital and returns are effectively guaranteed.
- Returns are completely tax-free (Exempt-Exempt-Exempt), unlike most fixed deposits.
- Deposits qualify for a deduction under Section 80C, up to ₹1.5 lakh a year.
- Partial withdrawals and loans are allowed after a few years, adding flexibility.
Frequently Asked Questions
What is the current PPF interest rate?
The PPF rate is set by the government and reviewed every quarter. It is 7.1% per annum at present. You can change the rate in the calculator to match the applicable rate for your period.
What is the maximum I can invest in PPF?
You can deposit up to ₹1.5 lakh per financial year across all your PPF accounts, with a minimum of ₹500 a year to keep the account active.
How long is the PPF lock-in?
A PPF account matures after 15 years. After that you can extend it in blocks of 5 years, with or without further contributions, and it keeps earning interest.
Is PPF interest taxable?
No. PPF falls under the Exempt-Exempt-Exempt (EEE) category — your deposits qualify for Section 80C deduction, and both the interest and the maturity amount are fully tax-free.
Is this PPF calculator accurate?
It uses the standard annual-compounding method used for PPF maturity estimates. Small differences from your actual statement can occur depending on your exact deposit dates each month, since PPF interest depends on the monthly minimum balance.
