PPF calculator

The Public Provident Fund is one of India's most popular long-term savings schemes: backed by the Government of India, completely tax-free, and ideal for retirement or a child's education. ThisPPF calculator shows what your yearly deposits grow to after the 15-year lock-in and after optional 5-year extensions, how much of it is interest, and your balance at the end of every year.

How to use it

  1. Enter how much you'll deposit each year (₹500 to ₹1.5 lakh).
  2. Check the interest rate — it's pre-filled with the current rate.
  3. Optionally extend by 5 or 10 years, with or without new deposits.

How PPF interest is calculated

Balance at year end = (Opening balance + Deposit) × (1 + rate)

Interest is worked out monthly on the lowest balance between the 5th and the end of the month, but credited once a year on 31 March — which is why depositing by 5 April matters.

Example

Depositing the maximum ₹1.5 lakh every year for 15 years at 7.1%, you invest ₹22.5 lakh and receive about ₹40.68 lakh at maturity — over ₹18 lakh of tax-free interest. Extend for 5 more years with deposits and it grows to roughly ₹66.6 lakh. Compare with a market-linked option using theSIP calculator, or plan for your daughter with theSukanya Samriddhi calculator.

Frequently asked questions

What is the current PPF interest rate?
The calculator starts at 7.1% a year, compounded annually — the rate in force when we last reviewed it (October 2026). The government reviews small-savings rates every quarter, so change the rate field if it has been revised.
How much can I invest in PPF?
At least ₹500 and at most ₹1.5 lakh in a financial year, in a lump sum or instalments. Deposits up to ₹1.5 lakh qualify for the Section 80C deduction under the old tax regime.
When should I deposit to earn the most interest?
PPF interest is calculated on the lowest balance between the 5th and the last day of each month. Depositing your yearly amount before 5 April earns interest for the whole year — this calculator assumes that.
What happens after 15 years?
You can close the account and withdraw everything tax-free, or extend it in blocks of 5 years — with fresh deposits, or without, in which case the balance keeps earning interest. Choose an extension above to see the effect.
Is PPF interest taxable?
No. PPF is EEE — deposits (under 80C, old regime), interest and the maturity amount are all tax-free.
