PPF, explained
Public Provident Fund
PPF is a government small-savings scheme for long-term saving. Annual contributions range from ₹500 to ₹1,50,000, subject to scheme rules.
Compounding over time
Interest is credited annually, so earlier interest can earn more interest. The example assumes ₹1.5 lakh deposited at the start of each financial year and a constant 7.1%; actual rates may change.
15-year term and maturity
The calculator shows 15 financial years. The scheme's actual maturity convention counts 15 years from the end of the opening financial year; check the actual maturity date with your provider. Extension blocks have separate conditions.
Tax benefits
Eligible PPF contributions may qualify under Section 80C within the overall ₹1.5 lakh limit under the old tax regime. PPF interest and eligible maturity proceeds are generally exempt, subject to current law and individual circumstances.
