- r is the interest rate that is represented in decimal form. For example, if the interest rate is 6%, you would use 0.06 in the formula to calculate the interest earned.
- n is the number of time rates at which the interest is compounded. It has common values that include annual compounding, semiannual compounding, quarterly, monthly, and daily compounding.
