PPF Calculator 2026 – Maturity Value at 7.1% Interest

Estimate the tax-free maturity value of your Public Provident Fund (PPF) account, year by year, at the current 7.1% interest rate.

How PPF interest is calculated

PPF interest is calculated monthly on the lowest balance between the 5th and the last day of each month, and credited once a year on 31 March. It compounds annually. This calculator assumes you deposit the full yearly amount before 5 April each year, which earns the maximum interest.

Closing balance each year = (Opening balance + Deposit) × (1 + rate) Maturity after 15 years ≈ D × [((1 + r)^15 − 1) ÷ r] × (1 + r)

Example

Investing the maximum ₹1,50,000 every year for 15 years at 7.1% builds a corpus of about ₹40.68 lakh. You invest ₹22.5 lakh and earn about ₹18.18 lakh in interest, all of it tax-free.
