How to Find Simple Interest Rate: Definition, Formula & Examples

Compound interest can be significantly greater than simple interest, particularly over the long term. If How to Find Simple Interest Rate: Definition, Formula & Examples the same mortgage had simple interest, you would only pay $80,000 in interest over the life of the loan.

The simple interest formula is fairly simple to compute and to remember as principal times rate times time. An example of a simple interest calculation would be a 3 year saving account at a 10% rate with an original balance of $1000. By inputting these variables into the formula, $1000 times 10% times 3 years would be $300. Can also be used if you have a loan term expressed in months or weeks. This formula is a little different in that «i» represents the interest rate during each period and «n» refers to the number of periods. Loans are usually made for a certain number of years, represented by «t» in the simple interest equation. However, for some loans, such as car loans, the length of the time period is expressed as a number of months.

Money Is Not Free To Borrow

Let’s say you loan $10,000 from a very generous friend for 2 years. You will pay interest at 6% per annum payable at the end of loan term i.e. 2 years. Interest expense calculation for the first year is easy, just apply the rate (6%) to the principal balance of $10,000 to get $600. This $600 is the accrued interest which you will pay at the end of the second year. The interest rate must be expressed on an annual basis, but if the time period is less than a year, then it must be adjusted for one year. For instance, if the interest rate is 12% per annum, but the problem pertains to the monthly interest rate, then it will be 1% (12%/12).

How to Find Simple Interest Rate: Definition, Formula & Examples

To compound interest, you add the interest to the principal each year of the loan. The following year, interest is paid on the total amount of principal and interest. It’s most common to see interest that is compounded each year, but interest may also be compounded monthly, or even weekly or daily. Similar to the interest rates applied to car loans, a credit card’s APR differs depending on the borrower’s financial information. The real interest rate takes the inflation rate into account. For example, when you borrow funds with a credit card, you might estimate how much interest you pay using simple interest. The effects of compounding become more pronounced over time, and that’s another reason why a 30-year mortgage is a bad candidate for simple interest calculations.

In the case of an investment, interest would be compounded until the end of the deposit term, or until you withdrew your investment. For example, if you have a 10-year mortgage on the house you bought, you would use 10 in the compound interest formula. You made a $50,000 down payment and took out a mortgage on the rest. Before continuing any further, Mark realizes that he must transform his interest rate into a decimal. He divides 1 by 100 to arrive at a usable decimal value of 0.01. The next part of the simple interest formula is just a bit of basic addition. Add 1 to the result of the previous multiplication to arrive at a whole number.

These costs will affect the total amount that you spend on the loan throughout the year, but they may not be included in the interest rate given to you by the lender.

Simple interest is based on the originalprincipal amountof a loan or deposit.

Similarly, you can as well earn an interest when you make a deposit of certain amount in a bank. Simple interest concept is majorly applied in various sectors including banking, mortgages, automobile, and other financial institutions. Typically expressed as a percentage, it amounts to a fee or extra charge the borrower pays thelenderfor the financed sum. The loan period or duration is the time that the principal amount is either borrowed or invested. It is usually given in years, but in some cases, it may be quoted in months or even days.

The larger the interest rate and the longer the time period, the more expensive the loan. Understanding the concept of simple interest is not only important for you to know how to solve problems in class, but also is a fundamental skill to help you manage your finances. With the basic knowledge on how the concepts work, you get empowered to make good financial decisions.

  • For example, for a principal amount of ₹15,000 at an annual interest rate of 5%, if you make a payment of ₹300 on May 1, ₹238.36 will be applied to the principal.
  • There may be times when you take a loan for a large purchase and the amount of the principal is not clear.
  • You know that 8%, written as a decimal, is 8.5% which changes to 0.085 as a decimal.
  • A $1,000 principal payment saves interest on that $1,000 and results in higher principal payments the next year, and higher the following year, and so on.

Now we can plug the information that we know into the simple interest formula and solve for the rate. In the following exercises, solve the problem using the simple interest formula. Table \(\PageIndex\) Interest Principal Rate Time $528.12 $ In the following exercises, solve the problem using the simple interest formula. We will use the simple interest formula to find the rate.

How To Find Simple Interest Rate: Definition, Formula & Examples

Let’s use another example to see how this might be different. Remember that in the formula, the principal \(P\) is the initial amount invested. While simple interest is a great tool for making rough estimates, it’s usually much more accurate to consider an interest calculation that accounts for the effects of compounding. Simple interest is the most basic way to calculate the amount you will earn or pay for an investment or loan. An easy trick for remembering this is to think of the word percent as «per 100.» You can convert a percentage into its decimal form by dividing it by 100.
