What is PPF?

Public Provident Fund (PPF) is a long-term government-backed savings scheme in India offering tax benefits under Section 80C. It has a lock-in period of 15 years and currently offers an interest rate of 7.1% per annum, compounded annually.

PPF Maturity Formula

The formula used to calculate PPF maturity is:

M = P × [((1+r)ⁿ − 1) / r] × (1+r)

• M = Maturity amount
• P = Yearly investment
• r = Annual interest rate ÷ 100
• n = Tenure in years

Example

Yearly investment of ₹1,50,000 at 7.1% for 15 years:
r = 0.071
M ≈ ₹40,68,209 (total invested ₹22,50,000, interest ≈ ₹18,18,209)

Frequently Asked Questions

Is PPF interest tax-free?

Yes, PPF falls under the EEE (Exempt-Exempt-Exempt) category — the investment, interest earned, and maturity amount are all tax-free.

Can I extend PPF beyond 15 years?

Yes, PPF can be extended in blocks of 5 years with or without fresh contributions after the initial 15-year lock-in.

What is the maximum yearly investment in PPF?

The maximum allowed yearly investment in PPF is ₹1,50,000. Amounts above this do not earn interest and are not eligible for tax deduction.

When should I invest in PPF each year?

To maximise returns, invest before the 5th of April each financial year so the full yearly deposit earns interest from the beginning of that month.
