About the Calculations
The calculator uses the compound interest formula:
A = P (1 + r/n)^(nt)
Where:
- A = the future value of the investment/loan, including interest
- P = the principal investment amount (initial deposit or loan amount)
- r = the annual interest rate (decimal)
- n = the number of times that interest is compounded per year
- t = the number of years the money is invested or borrowed for
This calculator provides accurate results based on user input but does not account for taxes, fees, or other potential charges that could affect the final amounts. It assumes that all other factors remain constant throughout the investment period.
