PPF Calculator

About the PPF calculator

The Public Provident Fund (PPF) is a government-backed long-term savings product with annual contributions, notified interest rates, and tax-free maturity under the current EEE structure. This calculator estimates how yearly deposits can compound into a maturity corpus.

Use it if you are planning a conservative retirement bucket, building a long-term tax-efficient allocation, or comparing PPF with ELSS, EPF, and tax-saving FDs. The calculator also estimates Section 80C tax savings when you have available deduction headroom.

The projection is an estimate. It applies the interest rate you enter for every year and assumes contributions are made at the start of each year, while actual PPF interest is calculated monthly and credited annually under scheme rules.

1. 1Enter your yearly investment: Add the annual amount you intend to deposit into PPF. The calculator applies the current ₹1.5 lakh annual cap for PPF benefits.
2. 2Set the interest rate: Enter the PPF rate you want to assume. The Government of India notifies this rate periodically, so use the latest notified rate for current planning.
3. 3Choose the duration: PPF has a 15-year base maturity. You can model longer periods to understand the effect of continuing the account in extension blocks.
4. 4Review tax savings: The tax-saved figure assumes the old tax regime, a 30% slab, and unused Section 80C capacity. If EPF, life insurance, or ELSS already uses the limit, actual savings can be lower.
5. 5Check the year-wise corpus: Use the yearly table to see how deposits and interest build the balance over time.

How is PPF interest calculated?

Bᵧ = (Bᵧ₋₁ + C) × (1 + r)

This calculator assumes the contribution is available for the full year. In actual PPF accounts, interest is calculated monthly on the lowest balance between the 5th and the end of each month, then credited annually.
