Ppf Calculator
Result
Illustrative beginning-of-year annual savings model; not an official Indian PPF maturity or tax calculation.
Formula
- Enter annual contributions, a hypothetical constant annual rate and years. The engine calculates the future value of beginning-of-year deposits using annuity-due math. Real PPF interest crediting, deposit timing, statutory term, changing rates, contribution caps and tax treatment are not implemented. At a zero rate the current motor cannot calculate its mathematical limit. Do not treat this result as a bank statement, official PPF estimate or investment promise.
- The main inputs are Annual contribution, Annual rate, Years. Enter them in the units and format shown in the calculator.
- Use monetary amounts, rates and time periods exactly as labeled; the result reflects the assumptions entered on this page.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Ppf
- Annual contribution: 1500
- Annual rate: 7.1 %
- Years: 15
Using Annual contribution = 1500, Annual rate (%) = 7.1, Years = 15, the calculated result is Maturity: 40682.092202879.

Frequently asked questions
What does the Ppf calculate?
Illustrative beginning-of-year annual savings model; not an official Indian PPF maturity or tax calculation.
Which values should I enter?
Enter Annual contribution, Annual rate, Years using the units and format shown beside each field.
What formula does this calculator use?
The calculator uses the following relationship: Hypothetical beginning-of-year level-contribution savings annuity: FV = A × ((1+r)^n − 1)/r × (1+r), where A is the entered annual contribution, r = annual percentage rate / 100 and n is years. This is an annuity-due model with a constant annual rate, NOT a full India Public Provident Fund (PPF) maturity calculation: actual scheme rules involve contribution timing, official changing interest rates, limits, prescribed compounding and other terms. At r = 0 the mathematical limit is FV=A×n, but the current engine divides by zero..
Why might my result differ from another source?
Results can differ when another source uses different units, rounding rules, conventions or assumptions. Compare the inputs and definitions before comparing results.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
