About this calculator
Enter how much you plan to put in each year. The calculator shows the maturity value, how much of it is your money and how much is interest, and the balance at the end of every year. It starts at 7.1%, the rate notified for October to December 2026; change it to see other scenarios.
How to use it
- Enter the amount you will deposit each financial year, between ₹500 and ₹1,50,000.
- Leave the rate at 7.1%, or try a lower or higher rate to see how a change would affect you.
- Choose 15 years for normal maturity, or a longer period if you plan to extend.
- Read the maturity value and open the yearly table to see how the balance builds.
The formula
- F
- the maturity value
- P
- the amount deposited each financial year
- i
- the yearly rate as a decimal (7.1% = 0.071)
- n
- the number of years (15 at maturity)
The final × (1 + i) means each year’s deposit is made at the start of the year, before 5 April, so it earns interest for the whole year.
Worked example
₹1,50,000 a year for 15 years at 7.1%
- P = ₹1,50,000, i = 0.071, n = 15. (1.071)15 = 2.79796.
- F = 1,50,000 × [(2.79796 − 1) ÷ 0.071] × 1.071 = ₹40,68,209.
- You deposit ₹22,50,000 in total, so the interest is ₹18,18,209.
What the result means
Interest makes up a large share of the maturity value because it compounds every year for 15 years. Most of the interest is earned in the later years, which is why extending a PPF account after maturity can be worthwhile.
PPF has been an exempt-exempt-exempt (EEE) product: the interest and the maturity amount are tax-free, and deposits can qualify for a deduction under the old tax regime. Check the tax rules in force for your year, as the deduction is not available under the new regime.
Assumptions
- The same amount is deposited every financial year, on or before 5 April.
- The interest rate stays the same for the whole period.
- Interest is compounded yearly and added at the end of each financial year, as in a real PPF account.
- No loans or partial withdrawals are taken.
Limitations
- The government reviews the PPF rate every quarter. It has been 7.1% since April 2020, but it can change, and the new rate applies to your whole balance.
- Real accounts work out interest monthly on the lowest balance between the 5th and the end of each month. Deposits made after the 5th of a month earn less than shown here.
- Deposits above ₹1,50,000 in a financial year earn no interest and are not allowed.
Frequently asked questions
What is the PPF interest rate now?
7.1% a year for October to December 2026, as notified by the Finance Ministry on 30 September 2026. The rate is reviewed every quarter.
When should I deposit in PPF?
On or before 5 April each year, or before the 5th of a month if you deposit monthly. Interest for each month is worked out on the lowest balance between the 5th and the end of the month.
Can I extend my PPF account after 15 years?
Yes, in blocks of 5 years, with or without fresh deposits. Choose 20, 25 or more years in the calculator to see the effect.
Is the PPF maturity amount taxable?
The interest and maturity amount have been tax-free. Confirm the current rules for your financial year before you file.
Can I withdraw before 15 years?
Partial withdrawals are allowed after the first few years, and loans against the balance are available in the early years, subject to scheme rules. Full early closure is allowed only in specific cases.
