What is PPF?
The Public Provident Fund is a government-backed long-term savings scheme run through post offices and banks. You can deposit from ₹500 to ₹1,50,000 in a financial year; the account runs for 15 years and can be extended in blocks of 5 years after that.
Deposits can be deducted under section 123 of the Income-tax Act, 2025 (formerly section 80C), up to ₹1,50,000 a year together with other eligible investments, but only if you opt out of the new tax regime, which allows no such deduction. Withdrawals and the maturity amount, interest included, are exempt from income tax under Schedule II of the Act. The interest rate is notified by the Ministry of Finance every quarter.

How is PPF calculated?
This calculator follows the actual PPF rule rather than a shortcut: interest for each month is calculated at one-twelfth of the annual rate on the balance held between the 5th and the end of that month, and the year's interest is credited to the account at the end of the financial year. A lump sum deposited in April before the 5th earns for all twelve months; monthly deposits earn slightly less. PPF has a 15-year term, extendable in blocks of 5 years.
PPF calculation example: ₹1.5 lakh a year for 15 years
Deposit the maximum ₹1,50,000 every year before 5 April, for 15 years, at 7.1% a year. You put in ₹22,50,000 and the account matures at ₹40,68,209 — ₹18,18,209 of it tax-free interest.
Pay the same amount as ₹12,500 before the 5th of every month instead, and it matures at ₹39,44,599: ₹1,23,610 less, because each month's deposit earns interest only from the month it lands.
7.1% is the rate notified for PPF for 1 July to 30 September 2026. Rates are revised every quarter.

Frequently asked questions
What is the current PPF interest rate?
7.1% a year for 1 July to 30 September 2026, unchanged since 1 April 2020. PPF interest is notified by the Ministry of Finance every quarter, so this calculator lets you enter the rate — confirm the current quarter's rate on the National Savings Institute or India Post website before relying on the figure.
How long does a PPF account run?
A PPF account has a term of 15 years, and can be extended in blocks of 5 years after maturity.
Is PPF interest tax free?
Withdrawals and the maturity amount, interest included, are exempt from income tax under Schedule II of the Income-tax Act, 2025. Deposits can also be deducted under section 123 (formerly section 80C), up to ₹1,50,000 a year together with other eligible investments, but only if you opt out of the new tax regime, which allows no such deduction.
When should I deposit into PPF to earn maximum interest?
Interest is calculated on the lowest balance between the close of the 5th day and the last day of each month, so depositing before the 5th of the month means that money earns interest for that month.
Why does this show a different figure from other PPF calculators?
Most calculators assume the full year's deposit is made in April, which earns interest for all twelve months. If you actually deposit monthly, later deposits earn for fewer months and the maturity value is a little lower. This calculator lets you choose which you do, so the figure matches your real pattern rather than a convenient assumption.
What is the PPF maturity amount for ₹1.5 lakh a year?
At 7.1%, depositing ₹1,50,000 before 5 April every year for 15 years gives ₹40,68,209: ₹22,50,000 deposited and ₹18,18,209 interest. Monthly deposits of ₹12,500 give ₹39,44,599.
What will ₹5,000 a month in PPF become after 15 years?
At 7.1%, ₹5,000 deposited before the 5th of every month for 15 years — ₹9,00,000 in all — matures at about ₹15,77,840.
