PPF sets a floor. What sits above it is a separate decision.

How PPF interest works
Interest is worked out every month on the lowest balance between the 5th and the last day of the month, and credited once a year, at the end of March. A deposit made by 5 April therefore earns interest for the whole year; this calculator assumes each year’s deposit is made by then.
balance = (balance + deposit) × (1 + rate), each year
What extending it does
The account matures after 15 years and can be extended in blocks of five, with or without fresh deposits. At the defaults, ₹1.5 lakh a year at 7.1% is worth ₹40,68,209 after 15 years. Keep depositing for 25 years and it is ₹1,03,08,015: the last ten years add more than the first fifteen, because by then the interest is being earned on a much larger balance.
The rate is not fixed
The government reviews the PPF rate every quarter. The default here, 7.1%, has been the scheme’s rate for several years; enter the current one, and remember that a projection over 15 years or more assumes it holds.
Assumptions this makes
- The same deposit every year, made by 5 April; interest at one rate for the whole term, compounded yearly.
- No partial withdrawals or loans against the account.
- Illustration, not a forecast and not investment advice.
