PPF calculator

How this is calculated

Annual deposits (by 5 April): balance_y = (balance_{y−1} + D) × (1 + R/100).
Monthly deposits (before the 5th): interest_y = Σ (R/1200) × lowest balance of each month; credited at year end.

Worked example

₹1,50,000 a year at 7.1% for 15 years (annual deposits): deposits ₹22,50,000, maturity ₹40,68,209.

Assumptions

• The rate stays at the value shown for every year; in reality it is reset each quarter.
• Deposits are made in time to earn interest for the whole month or year.

Frequently asked questions

₹500 to ₹1,50,000 per financial year, in multiples of ₹50. Excess deposits earn no interest.
