To calculate the simple interest on a loan, you can use the formula:

Simple Interest = Principal * Rate * Time

Here, the principal is $20,000, the interest rate is 8 percent (as a decimal, it is 0.08), and the time is 5 years.

Plugging these values into the formula, we get:

Simple Interest = $20,000 * 0.08 * 5
= $8,000

Therefore, the simple interest on a $20,000 loan at an interest rate of 8 percent after 5 years is $8,000.
