Public Provident Fund (PPF) Calculation Formula
F = P × [({(1 + r)^N} – 1) / r] × (1 + r)
- F: Maturity amount of the PPF account
- P: Annual installment deposited (₹500 to ₹1,50,000 per financial year)
- r: Annual interest rate (currently 7.1% per annum, reviewed quarterly by Ministry of Finance)
- N: Investment tenure in financial years (minimum 15 years, extendable in 5-year blocks)
Example: Depositing ₹1,50,000 annually for 15 years at 7.1% interest yields an invested amount of ₹22,50,000, interest earned of ₹18,18,209, and total tax-free maturity corpus of ₹40,68,209.
