About PPF Calculator
Public Provident Fund (PPF) is a long-term savings scheme with a 15-year lock-in period. The current interest rate is 7.1% compounded annually. After 15 years, you can extend the account indefinitely in blocks of 5 years. The maximum annual deposit is $150,000.
The Public Provident Fund (PPF) is a government-backed long-term savings scheme in India offering tax-free returns with a 15-year maturity period. The current interest rate is approximately 7.1% per annum, compounded annually. A maximum contribution of Rs. 1.5 lakh per year growing at 7.1% for 15 years accumulates to approximately Rs. 40.6 lakh. PPF offers EEE (Exempt-Exempt-Exempt) tax status — contributions are deductible under Section 80C, interest is tax-free, and maturity proceeds are tax-free, making it one of the most tax-efficient investment options for Indian investors.
When to Use This Calculator
PPF is ideal for long-term goals like retirement or a child's education fund. Use this calculator at the start of each financial year to plan your deposit strategy — you can deposit in one lump sum or spread across 12 monthly installments. It's also useful when comparing PPF against other EEE (Exempt-Exempt-Exempt) tax-saving instruments like ELSS or NPS to see which gives better returns for your investment horizon. If you're approaching the 15-year maturity, run the numbers to decide whether to extend your account in 5-year blocks.
How to Use This Calculator
Enter your annual deposit amount — the maximum allowed is $150,000 per year. Input your current age if you want to see extended projections beyond the 15-year lock-in period. The current PPF interest rate is 7.1% but you can adjust it if rates change. Click Calculate to see your maturity amount at 15 years along with extended projections for 20, 25, and 30 years. The chart shows how your balance grows over time with a clear marker at the 15-year maturity point. Try different deposit amounts to see how increasing your annual contribution accelerates your corpus growth.
How to Interpret Your Results
Suppose you deposit $150,000 annually at 7.1% for 15 years. The calculator shows your maturity amount as approximately $4,068,000, with total deposits of $2,250,000 and interest earned of $1,818,000. After 15 years, extending for another 5 years grows your corpus to about $6,431,000 without any additional deposits — that's the power of compounding at work. The chart shows your PPF balance curve steepening over time as compounding accelerates, with a notable inflection point at the 15-year maturity mark. Your extended projections help you visualize the benefit of continuing the account beyond the mandatory period.
