PPF interest is compounded annually and is entirely tax-free under the current rules. The government revises the rate every quarter.

How PPF maturity is calculated

Each year's PPF contribution earns interest annually, and that interest compounds along with the next year's deposit. The account has a minimum term of 15 years, extendable in blocks of 5 years after that.

Balance after each year = (Previous balance + This year's contribution) × (1 + annual rate)
Repeated for each year of the tenure

The maximum annual contribution allowed is ₹1,50,000, and interest earned is exempt from tax — one of the reasons PPF is a common long-term, low-risk savings choice.
