Final answer:
To calculate total interest on a loan with simple interest, multiply the principal by the interest rate and the time. Factors like the loan amount, interest rate, and loan term affect total interest paid. Prepaying a loan can reduce total interest significantly.

Understanding Simple Interest on Loans
To calculate the total interest on a loan using simple interest, you can use the formula Interest = Principal × Rate × Time. This means that if you have a $5,000 loan with a simple interest rate of 6% over three years, the interest is calculated as $5,000 × 0.06 × 3, which equals $900 in total interest. Similarly, if you received $500 in simple interest from a $10,000 loan over five years, the interest rate charged is found by rearranging the formula to Rate = Interest /(Principal × Time), which would be $500 /($10,000 × 5), resulting in an interest rate of 1% per year.
Factors that contribute to the total interest paid over a loan's life include the loan amount, the interest rate, and the term of the loan. To compare different loan scenarios, you can change the variables in the simple interest formula to see how each one affects the total interest paid. For instance, a higher interest rate or a longer term will generally result in more interest paid.
Prepaying a loan can have significant financial implications. It can greatly reduce the total interest paid because the principal amount of the loan is reduced earlier than scheduled, thereby decreasing the amount of interest that accrues over the life of the loan.
