We also recommend our Taylor rule calculator for a deeper dive into inflation, interest rates, and central bank policies. For example, for a deposit at a stated rate of 10% compounded monthly, the effective annual interest rate would be 10.47%. Banks will advertise the effective annual interest rate of 10.47% rather than the stated interest rate of 10%. For example, for a loan at a stated interest rate of 30%, compounded monthly, the effective annual interest rate would be 34.48%. Banks will typically advertise the stated interest rate of 30% rather than the effective interest rate of 34.48%. The effective annual interest rate of an investment is a rate where the compounding occurs more than once per year.
How to Calculate Effective Interest Rate: Formula & Examples
The effective annual interest rate allows you to determine the true return on investment (ROI). The effective annual interest rate is an important tool that allows the evaluation of the true return on an investment or true interest rate on a loan. The effective annual rate calculator is an easy way to restate an interest rate on a loan as an interest rate that is compounded annually. You can use the effective annual rate (EAR) calculator to compare the annual effective interest among loans with different nominal interest rates and/or different compounding intervals such as monthly, quarterly or daily. Effective annual rate (EAR), is also called the effective annual interest rate or the annual equivalent rate (AER).
How to calculate the effective interest rate
This figure is also often included in the prospectus and marketing documents prepared by the security issuers. That’s why the effective annual interest rate is an important financial concept to understand. You can compare various offers accurately only if you know their effective annual interest rates. The table below shows the difference in the effective annual rate when the compounding periods change.

- Therefore, by considering such extra costs, you can use the tool as an Annual Percentage Rate (APR) calculator and compare different offers.
- This rate may vary from the rate stated on the loan document, based on an analysis of several factors; a higher effective rate might lead a borrower to go to a different lender.
- For this reason, and also because of possible shortcomings, the calculator is created for advisory purposes only.
Investors, savers, or borrowers can take nominal rates with different compounding periods (i.e. one that compounds weekly, one that compounds monthly) to see which will be most beneficial to them. In this context, the EAR may be used as opposed to the nominal rate when communicate rates in an attempt to lure business of transactions. For example, if a bank offers a nominal interest rate of 5% per year on a savings account, and compounds interest monthly, the effective annual interest rate will be higher than 5%. Therefore, the bank should consider promoting the account at the EAR because that rate will appear higher. Investment B has a higher stated nominal interest rate, but the effective annual interest rate is lower than the effective rate for investment A. If an investor were to put, say, $5 million into one of these investments, the wrong decision would cost more than $5,800 per year.

A certificate of deposit (CD), a savings account, or a loan offer may be advertised with its nominal interest rate and effective annual interest rate. The nominal interest rate does not reflect the effects of compounding interest or even the fees that come with these financial products. Going back to the previously mentioned shortages of the nominal interest rate, if we take into account the effect of compounding interest, we obtain the Effective Annual Rate (EAR or EFF%). The concept of EAR is the same as that for the Annual Percentage Yield (APY), however, the latter form is applied mainly on investments or savings account. Since the compounding period may vary in different types of financial instruments, one of the main advantages of the Effective Annual Rate is that the financial products became comparable. In this context, the EAR may be used as opposed to the nominal rate when communicating rates in an attempt to lure business.
This rate may vary from the rate stated on the loan document, based on an analysis of several factors; a higher effective rate might lead a borrower to go to a different lender. These factors are the number of times the debt is compounded during the year, the actual amount of interest paid, and the amount the investor paid for the debt. Note that the altering the buying power of the money also affects the real value of the interest you pay or receive, especially over a long period.

If the investor does not agree that the market interest rate matches the stated interest rate to be paid by the borrower, the investor can bid less or more than the face amount to acquire the debt. Thus, if the market interest rate is higher than the face amount of the debt instrument, the borrower pays less for the debt, thereby creating a higher effective yield. Conversely if the market interest rate is lower than the face amount of https://www.kelleysbookkeeping.com/how-much-do-bookkeeping-services-for-small-2/ the debt instrument, the borrower is willing to pay more for the debt. The borrower may pay additional fees that are disguised forms of interest expense. A lender separates out these additional fees in order to drive down the stated interest rate on a loan – a practice that is more likely to attract a borrower. So based on nominal interest rate and the compounding per year, the effective rate is essentially the same for both loans.

The purpose of the effective annual interest rate is to make interest rates comparable regardless of their compounding periods. Investors, savers, or borrowers can take nominal rates with different compounding periods (e.g., one that compounds weekly, one that compounds monthly) to see which will be most beneficial to them. If an investor were to put $5 million into one of these investments, the wrong decision would cost more than $5,800 per year. The more the periods of compounding involved, the higher the ultimate effective interest rate will be. The primary difference between the effective annual interest rate and a nominal interest rate is the compounding periods.
