PPF Calculator formula
Balance at year end = (Opening balance + Deposit) × (1 + r)
r = annual rate ÷ 100. PPF interest is compounded yearly. This assumes you deposit before the 5th of April each year so the full year earns interest.
Worked example
₹1,50,000 every year for 15 years at 7.1%: total deposit ₹22,50,000.
Maturity value ≈ ₹40,68,209, so interest earned ≈ ₹18,18,209 — all tax-free.
