PPF Calculator
Calculate Public Provident Fund (PPF) maturity value, annual interest earned, and tax-free wealth creation under Section 80C.
About the PPF Calculator
The CalcNest PPF Calculator calculates the compounding maturity value and interest earnings from your Public Provident Fund account. PPF is one of India's most popular long-term debt instruments offering government-backed safety and triple tax-free benefits under Section 80C.
Mathematical Formula
A = P × [((1 + r)^n - 1) / r] × (1 + r) Where P is the yearly deposit amount, r is the annual statutory interest rate set by the Government of India (currently 7.1% p.a.), and n is the tenure in years (minimum 15 years).
Variables & Components
Worked Example: Maxing PPF with ₹1,50,000 Yearly for 15 Years at 7.1% p.a.
Suppose you deposit the maximum statutory limit of ₹1,50,000 annually into your PPF account before April 5th every year for the complete 15-year tenure at 7.1% interest.
Step-by-Step Calculation
- Total capital invested over 15 years = 15 × ₹1,50,000 = ₹22,50,000.
- Interest earned is compounded annually on the opening balance plus yearly deposit.
- Cumulative interest accumulated across 15 years = ₹18,18,209.
- Guaranteed tax-free maturity amount = ₹22,50,000 + ₹18,18,209 = ₹40,68,209.
