PPF Maturity Calculator: How Your PPF Corpus Is Calculated

How PPF works

The Public Provident Fund (PPF) is a government-backed, 15-year savings scheme. You can invest between ₹500 and ₹1,50,000 per financial year, the interest rate is set by the government each quarter, and interest is compounded annually. Contributions qualify for deduction under Section 80C, and the maturity amount is tax-free (EEE status).

How maturity is calculated

Interest each year is calculated on the lowest balance between the 5th and the last day of each month, then credited at year-end. Because it compounds annually for 15 years, even modest yearly contributions grow substantially.

Worked example: Investing ₹1,50,000 every year for 15 years at an assumed 7.1% p.a. grows to roughly ₹40.7 lakh at maturity — of which about ₹17.8 lakh is your contribution and the rest is compounded interest.

Tips to maximise PPF

• Invest before the 5th of the month so that contribution earns interest for the full month.
• Lumpsum early in April each year usually earns slightly more than spreading it out.
• After 15 years you can extend in 5-year blocks, with or without fresh contributions.
