PPF Calculator with Year-by-Year Table

How PPF interest is worked out

PPF interest is calculated every month on the lowest balance between the 5th and the last day of that month, then credited once, on 31 March. That one rule decides what a deposit earns. Money that reaches the account by 5 April earns interest for all twelve months. The same amount paid on 6 April misses April, and a deposit made in March earns nothing until the next year.

The calculator lets you pick your habit: one lump sum by 5 April, twelve equal monthly parts each paid by the 5th, or a lump sum on 31 March. At ₹1,50,000 a year for 15 years, the first comes to about ₹40.68 lakh, the monthly habit to ₹39.45 lakh and the March habit to ₹37.99 lakh. That ₹2.7 lakh gap comes purely from timing.

The rate is reset every quarter and applies to your whole balance. It has been 7.1% since April 2020.

Why the table can run to 16 years

Under the Public Provident Fund Scheme, 2019, the account matures 15 years after the end of the financial year in which you opened it. The opening year comes on top. Open the account in April 2026 and it matures on 1 April 2042, so you can deposit in 16 financial years, 2026-27 through 2041-42. Open it in March 2027 instead and the maturity date is the same, but your first deposit earns interest for only one month.

Most PPF calculators assume 15 deposits, and so does the default view here, so the figures match what banks quote. Pick your opening month to see the exact 16-year schedule.

When you can borrow or withdraw

Counting the opening year as year 1, the scheme allows:

• A loan in years 3 to 6, up to 25% of the balance at the end of the second year before the year you apply. One loan a year, and a new one only after the last is repaid. You pay 1% a year interest on it if you repay within 36 months, and 6% a year if you don't.
• A partial withdrawal from year 7, once a year, up to half of the lower of two balances: the one at the end of the fourth year before, and the one at the end of last year. Any loan has to be cleared first.
• Early closure after five years, but only for serious illness, higher education or a change of residency status. Interest is then recalculated at 1% less.

The Max loan and Max withdrawal columns apply these limits to your balances.

Extending the account after maturity

At maturity you can close the account or keep it running in blocks of five years. To keep depositing, submit Form 4 within one year of maturity. Withdrawals across each such block are capped at 60% of the balance at the start of that block, taken in one go or yearly. If you do nothing, the account continues without deposits: the balance keeps earning interest and you can take out any amount once a year. After a year without deposits, you cannot switch back to depositing.

Which way you extend makes a large difference. The standard ₹1,50,000 plan, extended for two blocks with deposits, reaches about ₹1.03 crore at the end of 2050-51. Without deposits it reaches about ₹80.8 lakh.

Tax: exempt at all three stages under the old regime

The Income-tax Act, 2025 has applied since 1 April 2026, so the section numbers have changed. Deposits up to ₹1,50,000 a year are deductible under section 123 (read with Schedule XV), which replaced section 80C. That ₹1.5 lakh limit is shared with EPF, ELSS, life insurance premiums and the other items on the list. Interest and the maturity amount are exempt under Schedule II (Table: Sl. No. 3), the successor to section 10(11).

The deduction is available only under the old regime: section 202, the new regime, disallows Chapter VIII deductions, section 123 included. Interest and maturity stay tax-free under both, because that exemption is not on the new regime's disallowed list. The income tax calculator helps you compare the two regimes.
