Calculations are based on the current 7.1% interest rate compounded annually. PPF interest rates are reviewed by the Government of India every quarter and are subject to market conditions.
To maximize your PPF interest, always invest between the 1st and 5th of every month. The interest is calculated on the lowest balance between the 5th and the end of the month. Missing this window by even a day means you lose out on returns for that entire month!
The PPF Calculator helps you estimate the maturity value of your Public Provident Fund account. PPF is India's most trusted long-term savings scheme — backed by the Government of India, offering 7.1% guaranteed returns and EEE tax status (Exempt-Exempt-Exempt: investment, interest, and maturity are all tax-free).
A maximum of ₹1.5 lakh can be invested per year. PPF has a 15-year lock-in with options for loans (year 3–6) and partial withdrawals (after year 7).
PPF interest is calculated on the minimum balance between the 5th and last day of each month and credited annually on March 31st. This means you should deposit before the 5th of each month to earn interest for that month. The formula compounds your deposits annually over 15 years.
F = P × [((1 + i)ⁿ - 1) / i]Where:
Rohan opens a PPF account at age 30 and deposits the maximum ₹1,50,000 per year for 15 years at 7.1% interest.
• Total Amount Invested: ₹22,50,000
• Total Interest Earned: ₹18,18,209 (completely tax-free!)
• Maturity Value at Age 45: ₹40,68,209
If Rohan extends for 5 more years (to age 50): Maturity jumps to ₹66,58,288 — adding ₹7.5L more in deposits but getting ₹25.9L more in returns due to compounding!
