About the PPF Calculator

The Public Provident Fund is a fifteen year government savings scheme with a rate reset each quarter and interest credited once a year. Because contributions repeat, there is no single closed form to memorise: the balance rolls forward year by year as closing = (opening + deposit) x (1 + r) when the deposit lands at the start of the year. This page runs that loop and prints every row, so opening balance, deposit, interest and closing balance are all visible.

Deposit timing is worth a real amount of money. Interest is calculated on the lowest balance between the fifth and the last day of each month, so money paid in before the fifth of April earns for the full year while a deposit made in March earns almost nothing that year. Switching the timing option shows the size of that gap over a full term, and it is usually large enough to justify a calendar reminder.

Contributions are capped at 150,000 rupees a year with a minimum of 500 to keep the account active, so those bounds are enforced here. The term is fifteen financial years and can be extended in blocks of five, which is why the years field accepts more than fifteen. Interest is exempt from tax and the maturity amount is exempt too, so the projected figure is what you keep. The rate does change, so rerun the projection when a new quarterly rate is announced. For a single lump sum instead of yearly deposits, use the FD Calculator.

How to use

  1. Enter your yearly deposit, up to the annual ceiling of 150,000.
  2. Set the current interest rate announced for the quarter.
  3. Choose fifteen years, or more if you plan to extend the account in five year blocks.
  4. Keep the deposit timing at the start of the year and compare it with the end of year option.

Common questions

What is the maximum I can deposit?
The annual ceiling is 150,000 rupees across all accounts you hold, with a minimum of 500 a year to keep the account from lapsing.
When should I deposit for the best return?
Before the fifth of April. Interest is worked out on the lowest balance between the fifth and the end of each month, so early money earns for the full year.
Can I withdraw before fifteen years?
Partial withdrawal is allowed from the seventh year, and loans against the balance are possible from the third year, both within limits.
Is the interest rate fixed for the whole term?
No, the government resets it every quarter. This projection assumes the rate you enter holds for the full period.
