How the money is calculated
- Interest is calculated every month on the lowest balance between the 5th and the end of that month, at the yearly rate ÷ 12.
- The month’s interest is not added to the balance straight away: the year’s interest is credited once, at the end of the financial year (31 March).
- A deposit made by 5 April earns interest for the whole year. "Every month" spreads the yearly amount into 12 deposits made by the 5th of each month, which earns a little less.
- The account matures after 15 full financial years and can be extended in blocks of 5 years. The rate is assumed to stay the same for every year, although the government can change it every quarter.
Each year: interest = Σ (balance after the month’s deposit × rate ÷ 12) over 12 months; closing balance = opening balance + deposits + interest

Tax
PPF is fully tax-free: deposits count towards the ₹1.5 lakh deduction under Section 123 of the Income-tax Act, 2025 (formerly Section 80C), only if you choose the old tax regime, and the interest and the maturity amount are not taxed. Tax rules are those of the Income-tax Act, 2025, in force from 1 April 2026; check your own position before relying on them.
Frequently asked questions
What is the current PPF interest rate?
7.1% a year for October–December 2026 (Q3 FY 2026-27), as notified by the Ministry of Finance on 30.09.2026. The rate is reviewed every quarter.
Why does depositing before 5 April matter?
PPF interest for a month is calculated on the lowest balance between the 5th and the last day of the month. Money deposited by 5 April therefore earns interest for all 12 months of the financial year.
Is PPF interest taxable?
No. PPF interest and the maturity amount are tax-free. The yearly deposit can also be deducted from taxable income under Section 123 (formerly 80C), but only under the old tax regime.
Can I continue PPF after 15 years?
Yes. You can extend the account in blocks of 5 years, with or without fresh deposits. Set the term above to 20, 25 or more years to see the effect of continuing deposits.
How much will ₹1.5 lakh a year in PPF become in 15 years?
At the current 7.1%, depositing ₹1,50,000 at the start of every year for 15 years gives about ₹40,68,209, of which ₹18,18,209 is interest. ₹50,000 a year gives about ₹13,56,070. The rate is reviewed every quarter, so the real figure will differ.
Can I withdraw from PPF before 15 years?
Partly. India Post states that a loan can be taken against the balance from the 3rd financial year and partial withdrawals are allowed from the 7th year. The full balance is paid at maturity after 15 years. Rules can change, so confirm at your post office or bank before acting.
What happens if I miss a year’s PPF deposit?
The account becomes inactive if the minimum ₹500 is not deposited in a year. India Post states it can be revived by paying ₹50 for each missed year along with the missed minimum deposits. Loans and withdrawals are not allowed while the account is inactive. Rules can change, so confirm at your post office or bank before acting.
