How PPF maturity is calculated
The Public Provident Fund is a long-term, government-backed savings scheme and one of the most popular fixed-income options in India. You invest a fixed amount each year, the balance earns a government-declared rate of interest — currently around 7.1% — and the whole thing is locked in for 15 years. Because the rate is fixed and the government guarantees it, your money grows steadily without any market risk.
Interest in PPF is compounded annually. This calculator assumes each year's deposit is made at the start of the year, so every rupee earns a full year of interest, and the accumulated balance keeps compounding year after year. The future value follows the formula FV = P × ((1+i)n − 1) / i × (1+i), where P is your yearly deposit, i is the annual rate and n is the number of years. The result splits the corpus into how much you put in and how much is interest.
The single biggest driver is time. Over a full 15-year term the interest can rival or exceed the amount you deposited, which is the power of long, uninterrupted compounding. You may invest between ₹500 and ₹1.5 lakh a year; staying near the upper limit and never missing a year maximises the final corpus.
What makes PPF especially attractive is its tax treatment. It enjoys EEE status: the deposit qualifies for a deduction under Section 80C in the old regime, the interest is completely tax-free, and the maturity amount is tax-free too. Few other instruments combine guaranteed returns with fully tax-free growth, which is why PPF is a cornerstone of many long-term and retirement portfolios.
Use this calculator to plan how much to invest each year to reach a goal, and to see how the corpus grows if you extend the account in 5-year blocks after maturity. The interest rate is set by the government each quarter, so revisit the figure periodically to keep your projection accurate.
Frequently asked questions
How is PPF interest calculated?
PPF interest is compounded annually. This calculator assumes each yearly deposit is made at the start of the year, so it earns a full year of interest, and the balance grows by the prevailing rate (currently around 7.1%) every year for the chosen tenure.
What is the PPF lock-in period?
A PPF account has a 15-year maturity. After that you can withdraw the full amount or extend the account in blocks of 5 years, with or without further contributions. Partial withdrawals are allowed from the seventh year.
How much can I invest in PPF each year?
You can deposit between ₹500 and ₹1,50,000 in a PPF account in a financial year. Deposits up to ₹1.5 lakh also qualify for a deduction under Section 80C in the old tax regime.
Is PPF tax-free?
Yes. PPF enjoys EEE status — the amount you invest is deductible under 80C, the interest earned is tax-free, and the maturity amount is tax-free too. This makes it one of the most tax-efficient fixed-income options in India.
Can I lose money in PPF?
No. PPF is backed by the Government of India and pays a fixed, government-declared rate, so the principal and interest are secure. The only variable is the interest rate, which the government can revise each quarter.
