Q. An account has a rate of 3.8%. Find the effective annual yield if the interest is compounded semiannually.The effective annual yield is □%.(Round to the nearest hundredth as needed.)
Identify Given Data: Identify the given annual nominal interest rate and the number of compounding periods per year.We have:Nominal annual interest rate r: 3.8% or 0.038 (as a decimal)Number of compounding periods per year n: 2 (since the interest is compounded semiannually)We need to calculate the effective annual yield (EAY).
Use EAY Formula: Use the formula for the effective annual yield when interest is compounded more than once per year.The formula for EAY is:EAY = (1+nr)n−1Where r is the nominal annual interest rate and n is the number of compounding periods per year.
Calculate EAY: Plug the values into the formula to calculate the effective annual yield.EAY=(1+20.038)2−1=(1+0.019)2−1=(1.019)2−1=1.019×1.019−1=1.038361−1=0.038361
Convert to Percentage: Convert the effective annual yield from decimal form to percentage and round to the nearest hundredth as needed.EAY=0.038361×100%=3.8361%Rounded to the nearest hundredth, the EAY is approximately 3.84%.
