How to use the PPF Calculator

  1. 1

    Enter how much you will deposit every year (₹500 to ₹1,50,000).

  2. 2

    Keep the rate at 7.1% or change it to test other rates.

  3. 3

    Choose the period: 15 years, or 20, 25 or 30 with extensions.

  4. 4

    See the maturity value, total interest and a year-by-year schedule.

PPF formula

Balance at year end = (Opening balance + Deposit) × (1 + rate)

Maturity = Σ Deposit × (1 + rate)^(years remaining)

Interest is worked out monthly on the lowest balance between the 5th and the last day of the month, and credited at the end of the year. Depositing before 5 April gets the full year’s interest — the calculator assumes you do.

Worked example

  • ₹1,50,000 deposited every year before 5 April for 15 years at 7.1%.
  • Total deposits: ₹22,50,000. Maturity value: ₹40,68,209, of which ₹18,18,209 is tax-free interest.

PPF rules at a glance

PPF is an EEE (exempt-exempt-exempt) investment in the old regime:

  • Deposits count towards the ₹1.5 lakh Section 123 (old sec. 80C) deduction (old regime only).
  • Interest and the maturity amount are tax-free in both regimes.
  • Partial withdrawals are allowed from the 7th financial year, and loans from the 3rd to the 6th year.
  • At maturity you can close the account or extend it in 5-year blocks, with or without fresh deposits.
