What is the current PPF interest rate?

The Public Provident Fund rate is 7.1% per annum for the April-June 2026 quarter. The government reviews and revises it every quarter. Interest is compounded annually.

How is PPF maturity calculated?

Each year's deposit is added to the balance and the whole balance earns interest, compounded yearly. Over the 15-year term this compounding builds a substantial tax-free corpus.

Yes. PPF has EEE status: the deposit qualifies for Section 80C deduction (up to Rs 1.5 lakh), the interest earned is tax-free, and the maturity amount is fully tax-free.

Can I extend my PPF account after 15 years?

Yes. After the initial 15-year lock-in, you can extend the account in blocks of 5 years, with or without further contributions, and it keeps earning interest.

What is PPF?

The Public Provident Fund (PPF) is a long-term savings scheme backed by the Government of India. It offers tax-free returns at a fixed rate (7.1% for the April-June 2026 quarter), a 15-year lock-in, and full EEE (Exempt-Exempt-Exempt) tax status - your deposit qualifies for Section 80C (under the old regime), the interest is tax-free, and the maturity is tax-free. Maximum yearly deposit is ₹1.5 lakh and minimum is ₹500. PPF is one of the most popular long-term tax-free savings instruments in India for risk-averse savers. The PPF rate is reviewed quarterly by the government.

Formula and method

Balance(y) = Σ Annual_Deposit × (1 + r)^(15 − t + 1)

Each year's deposit earns interest for the remaining years. PPF interest is compounded annually at the year-end rate. The formula sums up each deposit grown for its remaining years to give the maturity corpus.

Why PPF is special

EEE tax status. Deposit, interest and maturity all tax-free (deposit deduction under old regime only).
Backed by Government of India. Zero default risk.
Lock-in builds discipline. 15-year lock-in prevents impulsive withdrawal.
Partial withdrawal allowed. From year 7 onwards, up to 50% of the balance.
Joint with mutual funds. PPF for the safe foundation, equity SIPs for the growth on top.

Sample PPF corpus at ₹1.5 lakh/year deposit

Tenure	Total deposited	Maturity at 7.1%
10 years	₹15 lakh	≈ ₹21.4 lakh
15 years (full term)	₹22.5 lakh	≈ ₹40.7 lakh
20 years (1 extension)	₹30 lakh	≈ ₹66.6 lakh
25 years (2 extensions)	₹37.5 lakh	≈ ₹1.03 crore
