In this formula:

- r represents the nominal interest rate expressed as a decimal.

- n indicates the number of compounding periods per year.

- The term (1 + r) captures the growth due to the interest earned.

- Raising this to the power of (12/n) effectively annualizes the growth, as it adjusts for the frequency of compounding. By subtracting 1, you isolate the interest component, thus providing the AER as a decimal.
