About the PPF Calculator
What is the PPF Calculator?
The Public Provident Fund (PPF) is a government-backed, 15-year savings scheme. Deposits (₹500 to ₹1.5 lakh a year) qualify for the Section 80C deduction under the old tax regime, and both the interest and the maturity amount are tax-free — the EEE status that makes PPF one of India's most popular long-term savings products.
Enter your yearly contribution, the current interest rate (7.1% for Q2 FY 2025-26) and the number of years. The calculator assumes each year's deposit is made before 5 April, so it earns interest for the full year, and shows the maturity value, total invested and interest earned.
How to use the PPF Calculator
- Yearly Contribution (₹) (sample: 1,50,000)
- Interest Rate (% per year) (sample: 7.1)
- Investment Period (Years) (sample: 15)
- Press Calculate PPF (results also refresh as you type). The result card shows the Maturity Value, along with Total Invested and Interest Earned.
Formula used
Balanceₖ = (Balanceₖ₋₁ + D) × (1 + r)
- D = the yearly deposit
- r = the annual PPF interest rate
- k = the year, from 1 to the number of years
PPF interest is calculated monthly on the lowest balance between the 5th and the last day of the month and credited once a year, so depositing before the 5th (ideally before 5 April) earns the most.

Tips for using the PPF Calculator
- After 15 years you can extend PPF in blocks of 5 years, with or without fresh deposits.
- Partial withdrawals are allowed from the 7th financial year; loans against PPF from the 3rd to the 6th year.
- The PPF rate is reviewed every quarter by the government — update the rate for current projections.
