PPF Calculator

What is PPF Calculator?

The PPF (Public Provident Fund) Calculator projects your maturity amount, total interest earned, and year-wise account balance. PPF offers guaranteed, tax-free returns backed by the Government of India.

How to Calculate PPF Maturity

1. Enter your annual PPF contribution (maximum ₹1,50,000)
2. The current PPF interest rate (7.1%) is pre-filled — adjust if changed
3. Enter the number of years (minimum 15, extendable in 5-year blocks)
4. Click Calculate to see total maturity amount, interest earned, and year-wise balance table

How PPF Calculator is Calculated

PPF uses annual compounding: Maturity = Yearly deposit × [((1+r)ⁿ − 1) / r], where r = annual interest rate (currently 7.1%) and n = number of years (minimum 15).

Worked Example

Annual deposit ₹1,50,000 for 15 years at 7.1%: Total deposits = ₹22,50,000. Interest earned = ₹18,18,209. Maturity amount = ₹40,68,209 — completely tax-free.

Common Use Cases

• Long-term tax-free savings planning
• Section 80C deduction optimization
• Retirement corpus building
• Comparing PPF with FD and ELSS returns

Common Mistakes to Avoid

• Depositing after the 5th of the month — PPF interest is calculated on the lowest balance between the 5th and end of month. Deposit by April 5th to maximise interest.
• Not investing the full ₹1,50,000 annual limit — you miss both the higher maturity and the full 80C deduction benefit.
• Assuming the 7.1% rate is fixed forever — the rate is reviewed quarterly by the government and can change.
• Withdrawing from PPF before the 7th year — partial withdrawal is allowed only from the 7th year, and loan against PPF only from the 3rd year.
