How to use

- See the maturity amount and total interest.
Formula
Interest is compounded once a year. The calculator assumes you deposit at the start of each financial year (before 5 April), so every deposit earns interest for the full year.
Maturity = P × ((1 + r)n − 1) ÷ r × (1 + r)
Frequently asked questions
What is the current PPF interest rate?
7.1% a year for July–September 2026. The government reviews the rate every quarter, so check the latest rate before investing.
Is PPF tax-free?

Can I extend PPF after 15 years?
Yes, in blocks of 5 years, with or without new deposits. Set Years to 20, 25 or more to see the effect.
