The PPF Compounding Rules Explained

PPF interest calculation has specific rules:

  • Compounding Interval: Interest is compounded annually at the end of the fiscal year (31 March).
  • Calculation Basis: Although credited yearly, interest is computed monthly based on the lowest balance in the account between the 5th and the last day of each calendar month. Deposits made on or before the 5th earn interest for that month.
  • Formula: Balancey = (Balancey-1 + Deposit) × (1 + r)

Worked Example

Suppose you deposit ₹1,50,000 on 1 April every year for 15 years at a rate of 7.1%:

  • Year 1: Deposit ₹1,50,000. Interest earned: ₹10,650. Closing balance: ₹1,60,650.
  • Year 2: Deposit ₹1,50,000. Opening balance: ₹3,10,650. Interest: ₹22,056. Closing: ₹3,32,706.
  • At Year 15 maturity:
    • Total invested: ₹22,50,000
    • Total interest earned: ₹18,18,209
    • Maturity value: ₹40,68,209
