PPF Calculator

Enter your yearly deposit (₹500 to ₹1.5 lakh) and the period. The calculator assumes you deposit before 5 April so the money earns interest for the whole year, and shows the tax-free interest built up each year.

Quick answer

PPF interest is compounded yearly. Depositing ₹1,50,000 by 5 April every year for 15 years at 7.1% gives a maturity value of about ₹40.68 lakh on ₹22.5 lakh deposited. The PPF rate was 7.1% for July–September 2026; the government reviews it every quarter.

Frequently asked questions

Is PPF interest tax-free?

Yes. PPF has exempt-exempt-exempt status: deposits qualify for the old-regime 80C deduction, and interest and maturity are tax-free.

Why deposit before 5 April?

PPF interest for a month is calculated on the lowest balance between the 5th and the end of the month. Depositing before 5 April earns interest for all 12 months.

Can I extend PPF after 15 years?

Yes, in blocks of 5 years, with or without fresh deposits.
