What is PPF (Public Provident Fund)?
PPF (Public Provident Fund) is a long-term, government-backed savings scheme in India that offers guaranteed, tax-free returns. Introduced in 1968, PPF is one of the safest investment instruments — backed by the sovereign guarantee of the Government of India. The scheme has a 15-year lock-in period, extendable in 5-year blocks. Interest is compounded annually and credited at the end of each financial year. With an EEE (Exempt-Exempt-Exempt) tax status, PPF is unmatched for long-term wealth creation for conservative investors — both investment, interest, and maturity are completely tax-free. Accounts can be opened at any nationalized bank or post office.

PPF Formula and Calculation Method
PPF interest is compounded annually and credited to your account at the end of each financial year (March 31). The key rules that affect the calculation:
PPF Maturity Formula
M = P × [((1+r)^n − 1) ÷ r] × (1+r)
Where: M = Maturity amount, P = Annual investment, r = Annual interest rate (e.g. 0.071 for 7.1%), n = Number of years
Monthly to Annual Deposits
If you invest monthly, deposits made between April 1–5 earn interest for the full month. Deposits made after the 5th of any month earn interest only from the following month. Always invest before the 5th to maximise interest for that month.
Example Calculation (₹1,50,000/year · 7.1% · 15 years)
Total invested: ₹22,50,000 · Maturity amount: ₹40,68,209 · Interest earned: ₹18,18,209 (fully tax-free)
The maximum benefit: invest ₹1,50,000 on April 5 every year (not monthly) to earn interest on the full ₹1.5 lakh for all 12 months of the year.
