What is Effective Interest Rate?
The Effective Interest Rate (EIR) is the actual rate of return when you consider all financing costs, not merely the nominal interest rate. EIR encapsulates the true cost of a loan, reflecting its realistic economic impact.
Why is it Important?
Understanding EIR is essential for businesses and individuals seeking to measure the genuine cost of borrowed money. Unlike simple interest rates, EIR accounts for the influence of additional charges.
Effective Interest Rate vs. Annual Percentage Rate (APR)
While EIR provides a detailed picture of the actual interest incurred including transactional costs, APR generally denotes the yearly interest generated without encompassing every associated fee.
Calculating the Effective Interest Rate
::: example Mark took a one-year loan of $20,000 at his credit union. The loan comes with 3 discount points and a 6% face interest rate. Even though Mark borrowed $20,000, after paying the discount points, he effectively had $19,400. By the end of the year, he paid back $21,200, implying his effective interest rate was approximately 9.28%, rather than just the nominal 6%. :::
Crucial Example
Consider Abel, who borrows $10,000 on a one-year bank loan. He pays 2 discount points and endures a 5% face interest rate. By the end of the year, Abel repays $10,500. Initially, however, he received only $9,800 after the adjustment for discount points. This scenario demonstrates that his effective interest rate was closer to 7.14%, not 5%.
