How to Calculate Loan Interest
Loan interest is the price you pay for borrowing money. It is calculated as a percentage of the amount you borrow and is usually charged annually. The main types of loan are secured and unsecured, and the interest you pay depends on whether your loan is secured or unsecured. If you have a secured loan, the interest you pay will be lower than if you have an unsecured loan.

Introduction
Loan interest is usually expressed as a percentage of the total loan amount. It can be calculated using a simple interest formula or a more complex formula that takes compounding into account. You can use an online loan interest calculator to do the math for you, or you can do it yourself with a pencil and paper.
If you’re paying simple interest, the interest you owe is calculated based on the principal (the original amount borrowed) and the interest rate. The formula looks like this:
I = Prt
where:
I =Interest paid
P= Principal (original amount borrowed)
r= Annual interest rate (expressed as a decimal)
t= Loan term (in years)
For example, let’s say you borrow $200 at an annual interest rate of 10% for five years. Using the formula above, you would calculate the interest owed as follows:
I=($200)(0.10)(5)= $100
The total amount you would owe after five years would be $300 ($200 principal + $100 interest).
Compound interest is calculated based on the principal and the number of times that interest is compounded per year (the compound period). The more often that interest is compounded, the higher the total amount you will owe. The formula for calculating compound interest looks like this:
A = P (1+ r/n) ^ nt
where:
A= Total amount owed after t years including compound interest P= Principal r= Annual percentage rate (APR) as a decimal n= Number of compound periods per year t= Number of years
How to calculate loan interest
Loan interest is the amount of money that you pay for the use of someone else’s money. When you borrow money from a bank or other financial institution, they charge you an annual percentage rate (APR) for the use of their money. This APR is broken down into monthly payments, and that is the amount of interest that you pay each month. You can use a loan interest calculator to determine how much interest you will pay over the life of your loan.
Simple interest
Compound interest is interest that is charged not only on the original amount borrowed, but also on any accumulated interest from previous periods. In other words, compound interest is interest that “compounds” over time.
To calculate compound interest, you will need three pieces of information: the principal (the amount of money you are borrowing), the annual interest rate, and the number of years you will be borrowing the money.
The formula for calculating compound interest is:
A = P(1 + r/n)^(nt)
where:
A = the amount of money you will have after n years
P = the principal (the amount of money you are borrowing)
r = the annual interest rate (as a decimal)
n = the number of times per year that interest is compounded
t = the number of years you are borrowing the money
Compound interest
To calculate compound interest, start by multiplying the principal, which is the initial amount of money borrowed, by the number of time periods, which is how often interest is applied. Next, add 1 to this number and raise it to the power of the number of time periods. Finally, subtract 1 from your answer and multiply it by the interest rate. Compound interest is when you earn interest on your initial investment as well as on any previous Interest earned.
Conclusion
In conclusion, calculating loan interest can be a complex process. However, by using one of the many online calculators or following the instructions in this article, you can easily calculate the interest on your loan.
