CFA Level I · CFA Level I Exam · Working Capital and Liquidity

A firm purchases goods on terms of 2/10, net 40. Assuming a 365-day year, the approximate effective annual cost of forgoing the discount and paying on day 40 is closest to:

The effective annual cost is about 27.9 percent, found by compounding the 2.04 percent per-period cost (2/98) over 365/30 periods per year.

  1. A24.0%
  2. B37.2%Correct
  3. C44.6%

Explanation

Cost per period = 2/98 = 2.0408%. Periods per year = 365/30 = 12.1667. EAR = (1.020408)^12.1667 − 1 ≈ 27.9%... recomputing: ln(1.020408)=0.020204; ×12.1667=0.24582; e^0.24582=1.2788, giving 27.9%. Therefore none of the listed values match; the key is flawed.
