How do I use the PPF calculator?

1. Enter 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. Set 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. Choose 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. Review 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. Check the year-wise corpus: Use the yearly table to see how deposits and interest build the balance over time.

What is the lock-in period for PPF?

PPF has a minimum lock-in of 15 years. This calculator lets you project beyond 15 years as continued yearly contributions at the selected rate; it does not separately model extension modes with vs. without contributions.

What is the annual investment limit in PPF?

The minimum annual contribution is ₹500 and the maximum is ₹1.5 lakh across all deposits in a financial year. Deposits beyond ₹1.5 lakh do not earn PPF benefits.

PPF enjoys EEE tax treatment in India: eligible contribution deduction under Section 80C (within limits), tax-free interest, and tax-free maturity proceeds.

Can I withdraw before 15 years?

Partial withdrawals are allowed from specified years under PPF rules, and loans can be taken against balance in earlier years. However, full closure is generally restricted and subject to conditions.

Tax saved is old regime only: the new regime allows no Section 80C deduction, so this figure is ₹0 there. It also assumes available 80C headroom; if that is already used by EPF, insurance or ELSS, additional PPF may not increase tax savings.

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.

Frequently Asked Questions

Enter 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.
Set 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.
Choose 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.
Review 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.
Check the year-wise corpus
Use the yearly table to see how deposits and interest build the balance over time.

Bᵧ = (Bᵧ₋₁ + C) × (1 + r)

Bᵧ is the balance at the end of year y
Bᵧ₋₁ is the previous year's closing balance
C is the yearly contribution, capped at ₹1,50,000
r is the annual interest rate as a decimal

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.

Worked example

Suppose you invest ₹1,50,000 every year for 15 years and assume a 7.1% annual PPF rate.

Yearly investment: ₹1,50,000
Duration: 15 years
Interest rate: 7.1% p.a.
Total invested: ₹22,50,000
Interest earned: ₹18,18,209
Estimated tax saved: ₹6,75,000
Maturity amount: ₹40,68,209

You contribute ₹22.5 lakh over 15 years and the calculator projects a tax-free maturity amount of ₹40.68 lakh. The tax-saved figure assumes a 30% slab and full unused Section 80C headroom throughout the period.

Last reviewed 3 Sep 2026 · Sources: National Savings Institute: PPF interest rate, Income-tax Act, 2025 (Income Tax Department)

PPF currently has EEE tax treatment: eligible contribution deduction under Section 80C, tax-free interest, and tax-free maturity proceeds.
The annual contribution limit is ₹1.5 lakh. Deposits beyond the eligible limit do not increase PPF tax benefits or interest in this calculator.
The interest rate is not fixed for the full 15 years. It is notified periodically, so long-term projections should be stress-tested at lower rates.
PPF has a long lock-in. Partial withdrawals and loans are rule-bound, so do not use it for near-term liquidity needs.
Section 80C headroom is shared with EPF, ELSS, life insurance premiums, principal repayment on eligible home loans, and other deductions under the old regime.
