Formula & Mathematical Methodology: PPF Beginning-of-Year Annual Compounding Formula

By = (By−1 + Deposit) × (1 + r)
Balance_y = (Balance_{y−1} + Deposit) × (1 + r)
  • Deposit: Annual deposit made on or before April 5
  • r: Annual notified PPF interest rate (e.g., 0.071)

Rounding: Annual compounding rounded to nearest rupee.

Worked Example: ₹1,50,000/Year PPF Deposit at 7.1% p.a. for 15 Years

An investor deposits the full ₹1,50,000 Section 80C limit on April 1 every year for 15 years at 7.1% p.a.

  1. Total principal deposited over 15 years = ₹1,50,000 × 15 = ₹22,50,000.
  2. Compounding annually at 7.1% produces a closing maturity balance of ₹40,68,209.
  3. Total tax-exempt interest earned = ₹40,68,209 − ₹22,50,000 = ₹18,18,209.
Result: Maturity corpus is ₹40,68,209 (₹22.50L principal + ₹18.18L tax-free interest).
