PPF
Public Provident Fund — a 15-year government-backed savings scheme with tax-free interest and EEE tax treatment.
Definition
Public Provident Fund (PPF) is a long-term savings scheme run by the Indian government. Maximum contribution is ₹1.5 lakh per financial year. The interest rate is government-notified and revised quarterly — currently 7.1%. Interest is tax-free, the principal is deductible under Section 80C, and the maturity amount is tax-free too (EEE — Exempt-Exempt-Exempt).
Lock-in is 15 years from the financial year of opening. Partial withdrawals are allowed from year 7. The account can be extended in 5-year blocks indefinitely. PPF is one of the few EEE instruments still available — making its tax-equivalent return at the 30% slab approximately 10% pre-tax.
Formula
M = Σ (Cᵢ × (1+r)^(15−i+1)) for i=1 to 15Example
₹1.5 lakh annual deposit at 7.1% for 15 years → maturity ≈ ₹40.7 lakh on ₹22.5 lakh invested.
