Effective Cost of Trade Credit = [1 + (Disc.%/100 - Disc.%)]^[365 / (Days Credit Outstanding – Discount Period)] - 1

a. Effective cost of trade credit = [1 + (1.8/98.2)]^[365 / (30 - 10)] - 1 = 0.3930 or 39.30%

b. Effective cost of trade credit = [1 + (2.8/97.2)]^[365 / (30 - 10)] - 1 = 0.6792 or 67.92%

c. Effective cost of trade credit = [1 + (1.8/98.2)]^[365 / (60 - 10)] - 1 = 0.1418 or 14.18%

d. Effective cost of trade credit = [1 + (1.8/98.2)]^[365 / (30 - 15)] - 1 = 0.5558 or 55.58%
