Why PPF is a Must-Have in Your Portfolio
The Public Provident Fund (PPF) is a popular long-term investment scheme in India, backed by the Government. It offers safety, tax benefits under Section 80C, and completely tax-free maturity proceeds.
Interest in PPF is calculated on the lowest balance between the 5th and the last day of every month. However, compounding happens annually at the end of the financial year.
