If you are considering taking out a loan for $20,000 to be paid back over five years, you may be wondering what the monthly payments would be. This article will explain how to calculate the monthly payment for a loan of this size and at an annual rate of 8%. It will also explain the concept of interest rates and how they affect the total amount you will pay back over the course of the loan.

## Calculating the Monthly Payment

The formula used to calculate the monthly payment for a loan is as follows:

Monthly Payment = [Loan Amount × {Interest Rate + (Interest Rate/((1 + Interest Rate)^Number of Payments – 1))} ] / Number of Payments

In this case, the loan amount is $20,000, the interest rate is 8%, and the number of payments is 60 (5 years x 12 months). Plugging these numbers into the formula, the monthly payment would be $377.42.

## Understanding Interest Rates

Interest rates are the percentage of the loan amount that is charged as interest. In this example, the interest rate is 8%. This means that 8% of the loan amount will be charged as interest, and the remaining 92% will be the amount that is paid back over the course of the loan. Over the course of the loan, the total amount paid back will be $22,847.20, which is $2,847.20 more than the original loan amount.

Understanding how to calculate the monthly payment for a loan as well as understanding how interest rates can affect the total amount paid back can help you make an informed decision when it comes to taking out a loan. In this example, the monthly payment for a loan of $20,000 at an annual rate of 8% would be $377.42, and the total amount paid back over the course of the loan would be $22,847.20.
