CFA Level I · CFA Level I Exam · The Time Value of Money in Finance

A lender offers a loan at a 5.00% stated annual rate compounded quarterly. A borrower wants a rate with semiannual compounding that is equivalent in effective annual terms. The equivalent stated annual rate is closest to:

The equivalent semiannually compounded stated rate is about 5.03%. First convert 5% quarterly compounding to an effective annual rate of about 5.09%, then take the square root of 1.0509 minus one and double it. Fewer compounding periods require a slightly higher stated rate.

  1. A4.97%
  2. B5.03%Correct
  3. C5.06%

Explanation

EAR = (1.0125)^4 − 1 = 1.050945 − 1 = 5.0945%. Semiannual rate = (1.050945)^(1/2) − 1 = 0.025157 (1.025157^2 = 1.050945). Stated rate = 2 × 2.5157% = 5.03%. The 4.97% figure results from adjusting in the wrong direction; 5.06% comes from taking the EAR as a stated rate and rounding up.
