About the PPF Calculator

Estimate the maturity value and tax-free interest on a Public Provident Fund account. PPF pays 7.1% a year (October–December 2026), compounded yearly, on deposits from ₹500 to ₹1.5 lakh a year, for 15 years. Interest is calculated on the lowest balance between the 5th and the end of each month, so deposit before 5 April to earn the full year. Deposits qualify under Section 80C (old regime) and interest and maturity are tax-free.

The formula

Each year: balance = (balance + deposit) × (1 + rate)

Worked example

Example: Maturity value = ₹53,59,413

  1. Inputs: Yearly deposit: 1,50,000 ₹; Interest rate: 7.8%; Years: 17 years.
  2. Formula: Each year: balance = (balance + deposit) × (1 + rate)
  3. Result: Maturity value = ₹53,59,413

Things to keep in mind

  • Rates are reviewed every quarter; this uses the rate for October–December 2026.
