Formula & Worked Example

The math behind the PPF Calculator

Mathematical Formula

M = P \cdot \frac{(1+r)^n - 1}{r}
Where: - **M** is the PPF Maturity Amount. - **P** is the Annual Contribution (max ₹1.5 Lakh). - **r** is the Annual Interest Rate (currently 7.1%). - **n** is the Tenure (minimum 15 years, extendable in 5-year blocks). - Interest compounds annually. Contributions made before the 5th of each month earn interest for that month.

Step-by-Step Worked Example

Investing **₹1,50,000/year** at **7.1%** for **15 years**: - M = 1,50,000 × ((1.071)^15 - 1) / 0.071 - **M ≈ ₹40,68,209** - Total invested: ₹22,50,000 — Interest earned: **₹18,18,209** (all tax-free)

Frequently Asked Questions

Common questions about the PPF Calculator

Is PPF interest taxable?
No. PPF enjoys EEE (Exempt-Exempt-Exempt) tax status. Your contribution qualifies for deduction under 80C (up to ₹1.5 Lakh), the interest earned is completely tax-free, and the maturity amount is also tax-free. It is one of the safest tax-free investments.
Can I withdraw from PPF before 15 years?
Partial withdrawal is allowed from the 7th year onwards (up to 50% of balance at the end of the 4th year). Premature closure is only allowed after 5 years for specific reasons (serious illness, higher education). Loans against PPF are available from 3rd to 6th year.
What is the PPF interest rate for 2026?
The PPF interest rate for Q1 FY 2025-26 is 7.1% per annum, compounded annually. The rate is reviewed quarterly by the Ministry of Finance. It has been 7.1% since April 2020. Historical average (20 years) is approximately 8%.
Can I open more than one PPF account?
No. Only one PPF account per individual is allowed. Accounts opened in violation are considered irregular and earn 0% interest. You can have one PPF account in your name and act as guardian for your minor child's PPF account.
What happens to PPF after 15 years?
After 15 years, you can: (1) withdraw the entire maturity amount (tax-free), (2) extend for 5-year blocks with or without fresh contributions, (3) make partial withdrawals from the extended corpus. Extension retains the EEE tax benefit.
