Effective Annual Interest Rate: Definition, Formula, and Example


EAR calculations usually does not consider the impact of taxes on the returns. Taxes can significantly reduce the actual returns on investments or savings, and it’s important to factor them into any analysis. Though a given individual may truly earn at the EAR, their true return may be reduced by 20% or higher based on what individual tax bracket they reside in.

  • Unlike the fixed rates you’ll get with a certificate of deposit, rates for high-yield savings accounts are variable – meaning they move in lockstep with the federal funds rate.
  • That’s because there’s more than one way to express interest, and they don’t all account for the effect of compounding.
  • It’s the rate of you will pay or earn after taking into the account the impact of compounding.
  • As such, the investors lay greater emphasis on the number of compounding per year as a higher number of compounding means greater yield.
  • Nominal interest rates refer to the interest rates that are unadjusted for inflation.

EAR quotes are often not suitable for short-term investments as there are fewer compounding periods. More often, EAR is used for long-term investments as the impact of compounding may be significant. This approach may limit the vehicles in which EAR is calculated or communicated on. On the other hand, the EAR takes into account the effects of compounding interest. It represents the true annual interest rate after accounting for the effect of compounding interest, and it is typically higher than the nominal interest rate. The effective annual interest rate is important because, without it, borrowers might underestimate the true cost of a loan.

What Is an Effective Annual Interest Rate?

Investors and borrowers should also be aware of the effective interest rate, which takes the concept of compounding into account. In this scenario, while the nominal rate is 6%, the effective rate is 6.09%. The purpose of the effective annual interest rate is to make interest rates comparable regardless of their compounding best software for tax professionals periods. 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. Union Bank offers a nominal interest rate of 12% on its certificate of deposit to Mr. Obama, a bank client.

While the difference seems to be minor, if the underlying values are high and the transaction is considered over a considerable interval, the difference in interest earnings might become ample. This interest rate calculator is a compact tool that allows you to estimate various types of interest rate on either a loan or deposit account. You may find yourself in a situation where you take a loan and you know only the due payments, or you keep money in a bank and you know only your initial deposit and the current balance. In such circumstances, this calculator can help you find out the interest rate. The effective rate of interest determines an investment’s true return or a loan’s true interest rate. The “r” is your effective interest rate, “i” is the stated interest rate in its decimal format (3% is 0.03), and “n” is the number of times the interest compounds in a year.

A short survey on bank interest rates

We compare personal finance solutions such as loans, saving accounts, credit cards, and more. When you take out a loan, whether it’s a personal loan, payday loan, mortgage, or auto loan, you will see various interest rates, including the stated interest rate and annual percentage rate. Effective annual interest rates can help you understand how much interest you’ll actually earn when you’re saving or investing or how much you’ll have to pay when you’re borrowing. These can be important if you’re learning about financial literacy concepts and striving to achieve specific financial goals. But it is more common to hear about annual percentage rate (APR) (also known as “nominal interest”). When EAR refers to interest paid to an investor, it works much the same way.

What Is an Effective Interest Rate?: Compounding and Your Interest Costs

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.

Effective annual interest rate in a nutshell

The results of this calculator, due to rounding, should be considered as just a close approximation financially. For this reason, and also because of possible shortcomings, the calculator is created for advisory purposes only. Computing interest rates, particularly ones with sophisticated specifications, involves a series of equations where the interest rate is the base of an exponentiation. One efficient way to deal with such an equation is to apply the so-called Newton-Raphson method, which is a mathematical algorithm using an iteration procedure.

When banks are paying interest on your deposit account, the EAR is advertised to look more attractive than the stated interest rate. EAR can be used to evaluate interest payable on a loan or any debt or to assess earnings from an investment, such as a guaranteed investment certificate (GIC) or savings account. In most cases, business lenders want to make it seem like you’re paying less in interest. That means that most advertised interest rates you see are nominal interest rates―not effective.

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. Savings rates are likely at their peak based on signs from the central bank that multiple rate cuts are on the table this year. Unlike the fixed rates you’ll get with a certificate of deposit, rates for high-yield savings accounts are variable – meaning they move in lockstep with the federal funds rate. In general, when someone borrows from or make a deposit at a bank, the amount to be paid back or received is higher than the original amount, called the principal.

But your effective annual interest rate is 5.116% because that reflects how much interest you actually earned over the year. When interest compounds—interest accrues on the previously earned interest—the total interest amount can increase. And the rate of compounding—such as daily, monthly, quarterly or annually—affects how quickly the interest accrues. The nominal interest rate on your loan or savings determines how much interest applies to the principal balance. But it doesn’t necessarily tell you how much interest accrues over the year. Whether you’re borrowing money for a meaningful purchase or setting aside savings for your future goals, an account’s interest rate will affect how much you pay or earn.

Even if the nominal rate is positive, inflation can erode purchasing power so far that money loses its value when held onto. It’s just more common to use effective interest to describe costs for borrowing, while APY as a term gets used pretty exclusively for interest you earn (hence the “yield” in the name). A nominal rate gives you only part of the picture, while effective interest gets you closer to the real costs.
