Year 15 is the original maturity; every fifth year after it closes an extension block. Balances are at 31 March, after interest is credited.
How it works
The maths, in plain English.
How PPF interest works. Interest is worked out every month on the lowest balance between the 5th and the end of the month, and credited once a year on 31 March. A deposit made by 5 April therefore earns a full year's interest; twelve equal deposits made by the 5th of each month earn, on average, 13/24 of a year in the year they are made.
Fifteen years, then blocks of five. The account matures after fifteen complete financial years following the year it was opened. You may then close it, or extend it in blocks of five years — with fresh deposits, or without deposits while the balance keeps earning interest. The calculator counts fifteen deposits; an account opened early in a financial year can take a sixteenth.
Tax. Interest and the maturity amount are exempt under both regimes. The deposit itself qualifies for the Section 80C deduction (up to ₹1.5 lakh, shared with EPF, ELSS, life premiums and the rest) only in the old regime; the new regime gives no deduction for it. [VERIFY] The section numbers for these provisions under the Income-tax Act, 2025 should be confirmed before being quoted.
Assumptions. The rate you choose stays constant for the whole period — it will not, since it is reset quarterly. No loans or partial withdrawals. Interest is not rounded to the rupee as the post office or bank would. Deposits above ₹1.5 lakh a year earn no interest and are ignored.
