Initiating an early payment discount Gardner Company currently makes all sales on credit and offers no discount. The firm is considering offering a 5% discount for payment within 30 days. The firm's current average collection period is 60 days, sales are 40,000 units per month, selling price is $42 per unit, and variable cost per unit is $36. The firm expects that the change in credit terms will result in an increase in sales to 43,000 units, that 70% of the customers (and 70% of the dollar volume of sales) will take the discount and pay on day 30 , and the other customers will continue to pay the full invoice on day 60 . The company's cost of capital is 0.5% per month. Should it offer the discount? (Note: Assume a 365-day year.)
