9.5. Using the P&L Template for Decision-Making Analysis

The P&L template (refer to Figure 9-1) serves as a good model for decision-making analysis. To demonstrate, suppose that you're under intense competitive pressure to lower the sales price of one product you sell. This product is one "slice" of the total activity reported in Figure 9-1. Suppose that during the year (2009) you sold 1,000 units of the product at a $100 sales price, and the unit costs of this product are the same as in Figure 9-1.

Your competitors are undercutting your sales price, so you're thinking of cutting the sales price 10 percent next year, or $10 per unit. You predict that the price reduction will boost sales volume 25 percent and increase your market share. Seems like a good idea — or does it? You should run some numbers before making a final decision, just to be sure. Answer #1 in the earlier section "How did you make profit?" is the best method for this analysis. For the year just ended, this product generated $25,000 margin: $25 margin per unit × 1,000 units sold = $25,000 margin

Assuming your prediction about sales volume at the lower price is correct and sales volume increases to 1,250 units, and assuming that the variable costs for the product remain the same, next year you would earn $18,750 margin:

$15 margin per unit × 1,250 units sold =
             $18,750 margin

Cutting the sales price $10 reduces the ...
