What is a PPF (Public Provident Fund) calculator?
PPF is a government-backed long-term savings scheme with a 15-year lock-in. It falls under EEE (Exempt-Exempt-Exempt) tax status — your investment qualifies for 80C deduction, interest is tax-free, and maturity is tax-free. Current rate: 7.1% p.a. compounded annually.
Formula used
PPF Maturity = P × [(1+r)^n − 1] ÷ r × (1+r)
Where:
P = Annual investment
r = Annual interest rate (7.1% = 0.071)
n = Number of years
Limits: Min ₹500/year | Max ₹1,50,000/year
How to use this calculator
- Enter annual investment amount (maximum ₹1.5 lakh)
- Rate pre-filled at 7.1% — adjust if changed by government
- Enter investment period (minimum 15 years)
