How to calculate PPF maturity amount

Enter your yearly deposit and tenure to instantly see your PPF maturity amount, total interest earned, and a year-by-year breakdown.

  1. 01

    Enter your yearly deposit

    Type the amount you plan to deposit each year. The minimum is ₹500 and the maximum is ₹1,50,000 per financial year as per current PPF rules.

  2. 02

    Set the tenure

    PPF has a mandatory 15-year lock-in period. You can also calculate for extended periods (in 5-year blocks after maturity) to see the long-term compounding effect.

  3. 03

    Review the results

    The calculator shows your total investment, total interest earned, and maturity amount at the current 7.1% per annum interest rate (compounded annually).

  4. 04

    Explore the year-by-year breakdown

    Expand the detailed table to see your opening balance, deposit, interest earned, and closing balance for each year of the investment period.

What people use it for

PPF is India's most popular long-term tax-saving investment. Here's how the calculator helps you plan smarter.

Retirement planning

PPF is one of India's safest long-term savings instruments. Use the calculator to project your corpus at retirement and plan how much to deposit each year.

Tax saving under Section 80C

PPF deposits qualify for deduction under Section 80C (up to ₹1.5 lakh per year). Calculate how much you can invest to maximize your tax benefit.

Children's education fund

Open a PPF account in a minor's name and calculate how much it will grow by the time they reach college age, 15 to 18 years away.

Comparing investment options

Compare PPF returns against FD, mutual funds, or NPS to decide how to allocate your annual savings across different instruments.

Extension planning

After the initial 15-year term, PPF can be extended in 5-year blocks. Calculate the additional corpus you'd accumulate by extending rather than withdrawing.

Partial withdrawal planning

PPF allows partial withdrawals from year 7 onwards. Use the year-by-year breakdown to understand your balance at any point and plan withdrawals accordingly.

Worked example: the full ₹1.5 lakh a year for 15 years

The calculator adds each year's deposit at the start of the year and then adds that year's interest on the whole balance, at the rate you enter. At 7.1%, putting in the maximum ₹1,50,000 every year for 15 years means ₹22,50,000 in deposits and a maturity value of about ₹40,68,209, so ₹18,18,209 is interest. At ₹50,000 a year, maturity is about ₹13,56,070.

PeriodTotal depositedEstimated maturity at 7.1%
15 years (the minimum)₹22,50,000₹40,68,209
20 years (one extension)₹30,00,000₹66,58,288
25 years (two extensions)₹37,50,000₹1,03,08,015

After 15 years you can extend the account in blocks of 5 years, with or without new deposits. The last two rows show why people do: each extension adds far more interest than the deposits themselves, because the balance is already large.

How real PPF interest differs from the estimate

  • Interest is worked out monthly on the lowest balance between the 5th and the last day of each month, and credited once a year. Depositing by 5 April gets the whole year's interest on that deposit; the calculator assumes you always do.
  • The government sets the rate every quarter. It has been 7.1% for several years, but it can change, so the result is an estimate.
  • Interest and maturity are tax-free, and deposits count towards the Section 80C deduction under the old tax regime.
  • Partial withdrawals are allowed from the seventh financial year, and loans from the third to the sixth, both with limits.

Frequently asked questions

Common questions about PPF interest rates, lock-in rules, tax benefits, and how the calculator works.

The current PPF interest rate is 7.1% per annum, compounded annually. The rate is set by the Government of India and reviewed quarterly, though it has remained at 7.1% since April 2020.
Yes, completely free. No account required, no limits on calculations.
PPF has a mandatory 15-year lock-in period from the date of account opening. Premature closure is allowed only in specific circumstances (serious illness, higher education, change of residency status) after 5 years.
The minimum deposit is ₹500 per financial year and the maximum is ₹1,50,000 per financial year. Deposits can be made in a lump sum or in up to 12 installments per year.
Yes. PPF enjoys EEE (Exempt-Exempt-Exempt) tax status: the deposit qualifies for Section 80C deduction, the interest earned is tax-free, and the maturity amount is also tax-free.
Interest is calculated on the lowest balance between the 5th and last day of each month. To maximize interest, deposit before the 5th of each month. The interest is credited to the account at the end of each financial year.
Yes. After the initial 15-year term, you can extend the account in blocks of 5 years, either with continued deposits or without (the balance continues to earn interest). You must apply for extension within one year of maturity.
The calculator uses the current rate of 7.1% for all years. Since the PPF rate can change quarterly, actual returns may differ slightly. The calculation gives you a reliable estimate based on the current rate.
