Kim Mitchell, the new credit manager of the Vinson Corporation, was alarmed to find that Vinson sells on credit terms of net 90 days while industrywide credit terms have recently been lowered to net 30 days. On annual credit sales of $2.5 million, Vinson currently averages 95 days of sales in accounts receivable. Mitchell estimates that tightening the credit terms to 30 days would reduce annual sales to $2,375,000, but accounts receivable would drop to 35 days of sales and the savings on investment in them should more than overcome any loss in profit.

Vinson's variable cost ratio is 85 percent, and taxes are 40 percent. If the interest rate on funds invested in receivables is 18 percent, should the change in credit terms be made?
