# What is the Compound Interest on a Three-Year \$100.00 Loan

If you’re wondering how much interest you’ll pay on a loan, one of the factors you’ll need to consider is the compound interest rate. In this article, we’ll explain what compound interest is and how it’s applied to loans. We’ll also provide an example of how much interest you would pay on a three-year \$100.00 loan at a compound interest rate of 5%.

## What is Compound Interest?

Compound interest is when you earn interest on your principal investment plus any accumulated interest from previous periods. In other words, compound interest is “interest on interest.”

For example, let’s say you have a three-year \$100.00 loan with a 5% annual percentage rate (APR). The first year, you would owe \$5 in interest (\$100 x 0.05 = \$5). The second year, you would owe \$10.25 in interest (\$105 x 0.05 = \$5.25 + \$5 = \$10.25). The third year, you would owe \$15.76 in interest (\$110.25 x 0.05 = \$5.51 + \$10 = \$15.76). So, the total amount of compound interest you would pay on this loan would be \$31 over three years (\$5 + 10.25 + 15.76 = 31).

The main advantage of compound interest is that it can help your money grow faster than if it was simply earning simple interest because you are earning money on your initial investment plus any accumulated interest from previous periods.

The main disadvantage of compound interest is that it can also work against you if you have debt because you are payinginterest on your principal plus any accumulated interest from previous periods— which can mean that you end up paying more in total than if you just had simple interest.

## How is Compound Interest Calculated?

Compound interest is calculated using the following formula:

A = P(1 + r/n) ^nt

where:

A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for

example: What is the compound interest on a three-year \$100.00 loan at 6% interest, compounded monthly?

A = 100(1 + 0.06/12) ^(12*3)
A = 100(1.005) ^36 Future value of loan, including interest \$146.43

## What is the Compound Interest on a Three-Year \$100.00 Loan?

Through the years, many people have asked the question, “What is the compound interest on a three-year \$100.00 loan?” We have the answer!

To calculate the compound interest on a three-year \$100.00 loan, we first need to understand what compounding is. Compounding is when interest is earned on both the principal (the original amount of money borrowed) and on any previously earned interest. In other words, compounding refers to earning interest on interest.

Most loans are compounded annually, which means that you’ll earn interest once per year on the loan. However, some loans may be compounded more frequently, such as monthly or even daily. The frequency of compounding will affect your total interest payout over the life of the loan.

Assuming an annual compounding rate of 5%, here’s how much total interest you would pay over the course of three years on a \$100.00 loan:

Year 1: \$5.00
Year 2: \$5.25
Year 3: \$5.51
TOTAL: \$15.76

As you can see, your total interest payout increases each year as you earn interest on your previously earned interest. Over the course of three years, you would end up paying a total of \$15.76 in compound interest on a \$100.00 loan at a 5% annual rate.

## How Does Compound Interest Affect the Total Cost of a Loan?

The total cost of a loan is affected by compound interest, which is interest that accrues on the principal of the loan and on any previously unpaid interest. Compound interest can make a loan more expensive than a simple interest loan, as the borrower will end up paying interest on both the principal and any accrued interest.

## How Does Compound Interest Affect the Monthly Payment on a Loan?

To calculate the monthly compound interest payment on a loan, you will need to know the loan amount, the interest rate, and the number of years of the loan. The interest rate is usually given as an annual percentage rate (APR). The number of years is usually given as a term, such as 3 years or 5 years.

Compounding can have a significant effect on the monthly payment amount. For example, if you have a three-year \$100 loan at an APR of 5%, your monthly payments would be \$3.13 with simple interest and \$3.27 with compound interest. The difference of just \$0.14 may not seem like much, but it can add up over time!

Here is a more detailed example:

Suppose you take out a three-year, \$1,000 loan at 5% APR.
– With simple interest, you would pay \$50 in interest each year, for a total of \$150 in interest over the life of the loan. Your monthly payments would be \$41.67 (\$1,000 divided by 36 months).
– With compound interest, your monthly payment would be \$33.33 (\$1,000 divided by 30 months), but you would pay a total of\$164.17 in interest over the life of the loan.
In this instance, compound interest costs you an additional \$14.17 in interest over the life of the loan!

## What are Some Ways to Reduce the Cost of a Loan with Compound Interest?

Compound interest is when you earn interest on your original investment, plus any interest that has accrued. The longer you leave your money in the account, the more interest you will accrue, and the higher your balance will grow.

To reduce the cost of a loan with compound interest, you can:
-Make extra payments toward the principal balance of your loan.
-Pay off your loan as early as possible.
-Refinance your loan to a lower interest rate.
