PPF Maturity Calculation: How Much ₹1.5 Lakh a Year Becomes
Updated 25 September 2026 · 4 min read
The Public Provident Fund (PPF) is a 15-year, government-backed savings scheme. Deposits (₹500 to ₹1.5 lakh a year) qualify for Section 80C in the old tax regime, and the interest and maturity amount are completely tax-free.
How PPF interest is calculated
- Interest is worked out every month on the lowest balance between the 5th and the end of the month…
- …but it's added to your account only once a year, on 31 March — so it compounds yearly.
- The rate is set by the government every quarter.
So if you deposit the full ₹1.5 lakh before 5 April, it earns interest for all 12 months. At 7.1%, year one's interest is ₹10,650.
Maturity values at 7.1%
| Yearly deposit | Period | You deposit | Maturity value |
|---|---|---|---|
| ₹12,000 (₹1,000 a month) | 15 years | ₹1,80,000 | ₹3,25,457 |
| ₹1,00,000 | 15 years | ₹15,00,000 | ₹27,12,139 |
| ₹1,50,000 | 15 years | ₹22,50,000 | ₹40,68,209 |
| ₹1,50,000 | 20 years (one extension) | ₹30,00,000 | ₹66,58,288 |
| ₹1,50,000 | 25 years (two extensions) | ₹37,50,000 | ₹1,03,08,015 |
These examples assume the full yearly deposit is made by 5 April and a steady 7.1% rate. The government reviews the rate every quarter, so enter the current rate in the calculator for your own plan.

- Deposit early in the year — before 5 April — so the whole amount earns a full year's interest.
- Deposit every year. Missing the ₹500 minimum makes the account inactive until you pay a small penalty.
- Extend instead of closing if you don't need the money: the last 10 years of a 25-year PPF add more than the first 15.
Frequently asked questions
What is the PPF maturity amount for ₹1.5 lakh a year?
At 7.1% a year, depositing ₹1.5 lakh every year for 15 years (₹22.5 lakh in total) grows to about ₹40.68 lakh. The interest and maturity amount are tax-free.
Why should I deposit before the 5th of the month?
PPF interest for each month is calculated on the lowest balance between the 5th and the last day of the month. Money deposited after the 5th earns no interest for that month.
Can I continue PPF after 15 years?
Yes. You can extend the account in blocks of 5 years, with or without fresh deposits, by applying within a year of maturity.
