Maturity value, interest and a year-by-year table for a PPF account, in rupees with lakh and crore grouping.
A PPF account that gets ₹1,50,000 in every financial year, opened in April, at 7.1% grows to about ₹45,17,702 at maturity, of which ₹24,00,000 is your deposits and ₹21,17,702 is interest. The account matures 15 years after the end of the financial year it was opened in, so the term is the opening year plus 15 complete years, which is 16 yearly deposits. The page works year by year: interest is the yearly rate times the balance that earned it, and it is added at the end of the year, so next year's interest is worked on a larger balance. Year 1 of the example is (₹0 + ₹1,50,000) × 7.1% = ₹10,650, which leaves ₹1,60,650. The 7.1% is the rate announced for October to December 2026, unchanged since 1 April 2020. The government reviews the PPF rate every quarter, so the box is editable. The page shows whole rupees with lakh and crore grouping, and the year table shows each year's deposit, interest and closing balance.
PPF interest is worked on the lowest balance in an account between the 5th and the end of each month, and it is credited once a year. A deposit made after the 5th of a month therefore earns nothing for that month. The page offers three patterns. Once a year by 5 April means the whole deposit earns for all 12 months: ₹10,650 in year 1 for ₹1,50,000. Monthly by the 5th means 12 equal deposits, so ₹12,500 a month earns ₹5,769 in year 1 and the account ends the 16th year at about ₹43,80,435. Once a year in March means the deposit earns nothing in that year, and the account ends at about ₹42,18,209. These are the same total deposits with different results. The month you open the account matters too: the opening year runs to 31 March and earns interest only for the months left. Opening in October with ₹1,50,000 by the 5th earns 6 months of interest, ₹5,325, in the opening year, and the account reaches about ₹45,02,803.
The scheme rules allow a deposit of at least ₹500 and at most ₹1,50,000 in a financial year, in multiples of ₹50, and the page refuses other amounts. Twelve equal monthly deposits must each be a multiple of ₹50, so with the monthly pattern the yearly total must be a multiple of ₹600. The account matures on the expiry of 15 years from the end of the financial year in which it was opened. After maturity it can be extended in blocks of 5 years with further deposits, or kept without deposits at the prevailing rate. This page models the extension with deposits: one block makes 21 yearly deposits and the ₹1,50,000 example reaches about ₹72,91,677. You can add up to six blocks, which is 46 yearly deposits. The scheme rules are the Public Provident Fund Scheme, 2019, as published by the National Savings Institute.
The page keeps the same rate for every year, but the real rate can change each quarter, so the result is a projection and not a promise. It does not round interest to whole rupees each year, which a real account may do, so the last digits can differ. It leaves out partial withdrawals, loans against the account, tax rules and any change to the scheme. The deposit pattern is one of three simple ones, not every possible schedule. Nothing you type is stored or sent. The result is an estimate, not financial or tax advice, and the passbook of your bank or post office is the record that counts.
Work year by year: interest = (opening balance + deposit) × rate for a deposit made by 5 April, then balance = opening balance + deposit + interest. The account matures 15 years after the end of the opening financial year, so that is 16 yearly deposits. For ₹1,50,000 a year at 7.1% the maturity value is about ₹45,17,702. The page writes out year 1 under the result.
The rate announced for October to December 2026 is 7.1% a year, unchanged since 1 April 2020 according to the National Savings Institute rate table. The government can change it every quarter, so type a different rate in the box if it has moved.
The minimum is ₹500 and the maximum is ₹1,50,000 in a financial year, in multiples of ₹50, as the Public Provident Fund Scheme rules state. The box on this page accepts only such amounts, and 1,50,000 is the starting value.
PPF interest is worked on the lowest balance between the 5th and the end of the month. A deposit after the 5th does not count for that month. A ₹12,500 deposit on the 4th of each month earns ₹5,769 in year 1, but if it came after the 5th each time the interest would be lower.
After maturity you can extend the account in blocks of 5 years and keep depositing. One block makes 21 yearly deposits, and ₹1,50,000 a year at 7.1% then reaches about ₹72,91,677. Choose the number of blocks in Extensions of 5 years.
