What is a Public Provident Fund (PPF)?
The Public Provident Fund (PPF) is a popular long-term investment scheme offered by the Government of India with sovereign guarantee. PPF falls under the Exempt-Exempt-Exempt (EEE) category — your deposit, interest earned, and maturity amount are all completely tax-free.
PPF Compound Interest Formula
F = P [((1+i)^n-1)/i]
Where F is the maturity amount, P is the annual installment, n is the number of years (typically 15), and i is the interest rate (currently 7.1%).
