How PPF interest is calculated
A PPF account earns a government-declared interest rate (currently 7.1% per year), compounded annually. Each year’s deposit, plus the running balance, earns interest that is credited at year-end. Over the standard 15-year term this compounding builds a sizeable, fully tax-free corpus.
Worked example
Depositing the maximum ₹1,50,000 every year for 15 years at 7.1% grows to roughly ₹40.68 lakh. You would have invested ₹22.5 lakh, so about ₹18 lakh is tax-free interest earned through compounding.
Good to know
Deposit limits
You can invest between ₹500 and ₹1,50,000 per financial year, in a lump sum or up to 12 instalments. Deposit before the 5th of the month to earn that month’s interest.
Tenure & extension
PPF matures in 15 years and can be extended in blocks of 5 years, with or without further contributions.
Loans & withdrawals
Loans are available from year 3, and partial withdrawals from year 7, giving some liquidity before maturity.

Frequently asked questions
What is the current PPF interest rate?
The PPF interest rate is 7.1% per year, compounded annually. It is reviewed by the government every quarter.
How is PPF maturity calculated?
Each year’s deposit and the existing balance earn interest at the declared rate, compounded annually and credited at year-end. After 15 years the accumulated balance is your maturity amount.
Is PPF tax-free?
Yes. PPF has EEE status — deposits are deductible under Section 80C, the interest is exempt, and the maturity proceeds are tax-free.
What is the maximum I can invest in PPF?
You can deposit up to ₹1,50,000 per financial year, with a minimum of ₹500. Amounts above the limit do not earn interest.
Can I extend my PPF account after 15 years?
Yes, in blocks of 5 years, either continuing contributions or leaving the balance to keep earning interest.
When should I deposit to maximise interest?
Interest is calculated on the lowest balance between the 5th and the end of each month, so depositing before the 5th of the month — ideally early in the financial year — earns the most.
