About the PPF Calculator
The Public Provident Fund (PPF) is a government-backed savings scheme with a 15-year lock-in. The interest rate is set by the government and the interest is tax-free under current rules.
Enter your yearly deposit (up to ₹1.5 lakh), the interest rate and the period to see the maturity amount.
Formula used
Each year: balance = (balance + yearly deposit) × (1 + r/100). This assumes the deposit is made at the start of the year.
Frequently asked questions
What is the maximum PPF investment?
₹1.5 lakh per financial year.
Can I extend a PPF account after 15 years?
Yes, in blocks of 5 years, with or without further deposits.
Why is my bank statement different?
The government revises the rate periodically and interest is calculated on the lowest monthly balance, so actual figures can differ slightly.
