What is a PPF Calculator?

The Public Provident Fund remains one of the few investment options in India that's completely government-backed, tax-free at every stage, and still delivers a steady, respectable return year after year. This calculator shows exactly how a fixed yearly deposit into your PPF account grows over the mandatory 15-year lock-in, using the current interest rate declared by the government each quarter.

PPF Maturity Formula

The calculator compounds annually, adding each year's deposit before applying interest for that year:

Balance (each year) = (Previous Balance + Annual Deposit) × (1 + Rate ÷ 100)

This step repeats once for every year of the tenure (typically 15 years), since PPF interest is credited annually, not monthly.

Worked Example

Deposit the maximum PPF limit of ₹1,50,000 every year for 15 years at the current rate of 7.1% per annum:

Year 1: (0 + 1,50,000) × 1.071 = ₹1,60,650
... (compounds each subsequent year) ...
Year 15: Maturity Value ≈ ₹40,64,000

Over 15 years you'd have deposited a total of ₹22,50,000 from your own pocket, and the account would have earned roughly ₹18,14,000 in interest — all of it completely tax-free.

How to Use This Calculator

  1. Enter your Annual Investment (up to ₹1,50,000 to claim the full Section 80C benefit).
  2. Enter the Tenure in years (default and minimum is 15).
  3. Enter the current Interest Rate as declared by the government.
  4. Click Calculate to see your maturity value and total interest earned.
💡 Tip: PPF enjoys "EEE" tax status — your deposit qualifies for a Section 80C deduction, the interest earned is tax-free, and the maturity amount is tax-free too. After 15 years, you can extend the account in blocks of 5 years, with or without making further contributions.

If you're deciding between PPF and market-linked options for retirement, the NPS Calculator makes a useful comparison since it also carries tax benefits under Section 80C.
