A Loan That Compounds Interest Monthly Has An Ear Of 14.40 Percent. What Is The Apr?

 To calculate the Annual Percentage Rate (APR) from the Effective Annual Rate (EAR), we can use the formula:

𝐴𝑃𝑅=(1+𝐸𝐴𝑅𝑛)𝑛1

Where:

  • 𝐸𝐴𝑅 is the Effective Annual Rate (in decimal form),
  • 𝑛 is the number of compounding periods per year.

Given that the loan compounds interest monthly (𝑛=12) and the EAR is 14.40% (or 0.144 in decimal form), we can plug these values into the formula:

𝐴𝑃𝑅=(1+0.14412)121

𝐴𝑃𝑅=(1+0.012)121

𝐴𝑃𝑅=(1.012)121

𝐴𝑃𝑅=1.1268251

𝐴𝑃𝑅0.126825

To express the APR as a percentage, we multiply by 100:

𝐴𝑃𝑅0.126825×100%

𝐴𝑃𝑅12.6825%

So, the Annual Percentage Rate (APR) for the loan is approximately 12.6825%.
