PPF Calculator
Project your Public Provident Fund balance over the 15-year lock-in with annual compounding.
About the PPF Calculator
The Public Provident Fund (PPF) is a government-backed, tax-free savings scheme with a 15-year lock-in — one of the safest long-term instruments available to Indians. The AlarmDaddy PPF Calculator projects your year-by-year balance and the maturity value based on your annual contribution and the prevailing PPF interest rate (currently around 7.1%, revised quarterly by the government).
Enter your yearly investment (the PPF limit is ₹1.5 lakh per financial year) and the calculator compounds it annually for 15 years, showing the maturity corpus and total interest. Because PPF interest and maturity are completely tax-free under the EEE regime, the effective return is higher than a comparable taxable FD. The calculator also lets you see the impact of contributing the full ₹1.5 lakh every year versus a smaller amount.
How to use this calculator
- 1Enter your yearly PPF contribution (maximum ₹1,50,000).
- 2Enter the current PPF interest rate (about 7.1% in 2026).
- 3The tenure is fixed at 15 years (extendable in 5-year blocks).
- 4Read the maturity value and total tax-free interest.
The formula
PPF compounds annually. Each year the previous balance plus the new deposit earns the PPF rate r. After 15 years the accumulated balance is the maturity value. Interest is calculated on the lowest balance between the 5th and last day of each month, so depositing before the 5th of April maximises returns.
