About the PPF Calculator
PPF calculator is a perennial top search in Indian personal finance, and for good reason — the Public Provident Fund is one of the most trusted long-term savings instruments in the country, backed by the government, offering tax-free interest, and locked in for a minimum of 15 years. This calculator shows exactly how your yearly PPF contributions grow over that period, or beyond, at the prevailing interest rate.
PPF works on annual compounding: whatever you deposit in a financial year earns interest for that year, and both principal and interest carry forward and compound again the next year, and so on until maturity. You can deposit anywhere from ₹500 to ₹1.5 lakh per year, and the interest rate is set by the government every quarter (this calculator defaults to a recent representative rate, which you can adjust to match the current declared rate). PPF falls under the EEE tax category — your contribution qualifies for a Section 80C deduction (old regime only), the interest earned is tax-free, and the maturity amount is also tax-free, making it one of the few triple-tax-advantaged instruments available to individuals. This calculator is useful for planning how much to contribute annually to reach a specific maturity goal, seeing the difference between depositing early in the financial year (April) versus late (March) — since PPF interest is calculated on the lowest balance between the 5th and end of each month — or simply projecting your retirement-linked PPF corpus if you extend it in 5-year blocks after the initial 15-year lock-in.
