How PPF interest is calculated

PPF interest is worked out monthly on the lowest balance after the 5th, and credited once a year on 31 March, where it compounds. Deposit ₹1.5 lakh every year before 5 April for 15 years at 7.1% and you get about ₹40.68 lakh — ₹22.5 lakh deposited and ₹18.18 lakh interest, all tax-free.

Who PPF suits

PPF is government-backed and has a 15-year lock-in with partial withdrawals from year 7. It suits the safe, long-term part of your savings: a child's education, retirement, or balancing riskier equity investments.

Rates change

The rate is reset each quarter, so treat long-range results as estimates. Change the rate field to see how 7% or 7.5% would affect maturity.

Questions

What is the current PPF interest rate?

PPF pays 7.1% a year for the July–September 2026 quarter. The government reviews small-savings rates every quarter; the rate has stayed at 7.1% since April 2020.

How much can I invest in PPF?

At least ₹500 and at most ₹1,50,000 per financial year, in one go or in instalments. Deposits above ₹1.5 lakh earn no interest and get no tax benefit.

When should I deposit in PPF to earn the most interest?

Interest for each month is calculated on the lowest balance between the 5th and the end of the month. Depositing before 5 April earns interest for the full year — this calculator assumes that.

Is PPF tax-free?

In the old regime, deposits qualify for the ₹1.5 lakh deduction, and interest and maturity are fully tax-free (EEE). In the new regime there is no deduction, but interest and maturity are still tax-free.

Can I extend PPF after 15 years?

Yes, in blocks of 5 years, with or without fresh deposits. Submit Form H within a year of maturity to continue contributing.
