Example
Deposit ₹1,50,000 at the start of every year for 15 years at the current 7.1% rate. You invest ₹22,50,000 in total, and each year's balance plus the new deposit compounds at 7.1% — giving a maturity value of about ₹40,68,209, of which roughly ₹18,18,209 is completely tax-free interest.
How it works
The calculator compounds annually: each year the new deposit is added and the whole balance earns a year of interest, bal = (bal + p) × (1 + rate ÷ 100), repeated for the number of years. Total invested = p × years, and total interest = maturity value − total invested. In a real PPF account, interest is calculated monthly on the lowest balance between the 5th and the end of the month and credited once a year — depositing before April 5th (or the 5th of each month) earns the maximum interest, which is what this yearly model assumes.
Good to know
The Public Provident Fund is a Government of India small-savings scheme, open at post offices and most banks, whose principal and interest carry a sovereign guarantee — there is no market or credit risk. The interest rate is set every quarter by the Ministry of Finance and has stood at 7.1% per annum since April 2020. You can deposit a minimum of ₹500 and a maximum of ₹1.5 lakh per financial year (in one go or in instalments); depositing more than the cap earns no interest on the excess, and missing the ₹500 minimum makes the account inactive until a small penalty revives it.
PPF enjoys full EEE (exempt-exempt-exempt) tax status: deposits qualify for deduction under Section 80C up to ₹1.5 lakh, the interest earned is tax-free, and the entire maturity amount is tax-free too. That makes the 7.1% rate worth considerably more than a fixed deposit paying the same number, since FD interest is taxed at your slab — for someone in the 30% bracket, a taxable deposit would need to yield over 10% to match PPF after tax. PPF balances are also protected from attachment by court order in respect of debt, adding a layer of asset protection.
The trade-off is liquidity. A PPF account has a 15-year lock-in from the end of the financial year of opening, after which you can withdraw everything or extend in blocks of 5 years — with or without fresh contributions — indefinitely. Partial withdrawals are allowed from the 7th financial year (up to 50% of the balance at the end of the 4th preceding year), and a loan facility is available between the 3rd and 6th years at a modest rate over the PPF rate. Premature closure is permitted only in specific cases such as serious illness or higher education, with an interest penalty.
Because the rate resets quarterly, this projection assumes today's rate holds for the full term — over 15 years the actual credited rates will drift with government bond yields, as they have historically ranged between 7.1% and 12%. Timing matters too: interest each month is paid on the lowest balance between the 5th and month-end, so a lump-sum deposit before April 5th earns interest for the entire year, while a deposit on April 20th loses a month. Verify the prevailing rate and rules on the India Post or National Savings Institute site before planning around the figure.
Frequently asked questions
What is the current PPF interest rate?
The PPF rate is 7.1% per annum, compounded annually. It is reviewed and notified every quarter by the Ministry of Finance, so it can change during your 15-year term — this calculator assumes the rate you enter stays constant throughout.
Is PPF maturity amount tax-free?
Yes. PPF has EEE status: deposits up to ₹1.5 lakh a year qualify for Section 80C deduction, the interest is exempt from tax, and the full maturity amount is tax-free. No TDS is deducted on withdrawal.
Can I withdraw from PPF before 15 years?
Partially, yes. From the 7th financial year you can withdraw up to 50% of the eligible balance once a year, and a loan facility is available between the 3rd and 6th years. Full premature closure is allowed only for specific reasons like serious illness or higher education, with a 1% interest penalty.

People also ask
How much will ₹1.5 lakh per year in PPF give after 15 years?
At the current 7.1% rate, depositing ₹1.5 lakh at the start of each year grows to about ₹40.68 lakh at maturity — ₹22.5 lakh invested plus roughly ₹18.18 lakh of tax-free interest. The actual figure will vary as the government revises the rate each quarter.
What happens to a PPF account after 15 years?
You can withdraw the full balance tax-free, or extend the account in blocks of 5 years — either with fresh deposits (by submitting the extension form within a year of maturity) or without deposits, where the balance simply keeps earning interest with one withdrawal allowed per year.
What is the minimum and maximum PPF deposit per year?
You must deposit at least ₹500 each financial year to keep the account active, and the maximum that earns interest and 80C benefit is ₹1.5 lakh across all your PPF accounts combined, including a minor child's account you operate.
