Row Contains Explanation 3 Fixed values Seasonality factor: sales are higher in quarters 2 and 4, and lower in quarters 1 and 3. 5 =35*B3*(B11+3000)^0.5 Forecast for units sold each quarter: row 3 contains the seasonality factor; row 11 contains the cost of advertising. 6 =B5*\$B\$18 Sales revenue: forecast for units sold (row 5) times price (cell B18). 7 =B5*\$B\$19 Cost of sales: forecast for units sold (row 5) times product cost (cell B19). 8 =B6-B7 Gross margin: sales revenues (row 6) minus cost of sales (row 7). 10 Fixed values Sales personnel expenses. 11 Fixed values Advertising budget (about 6.3% of sales). 12 =0.15*B6 Corporate overhead expenses: sales revenues (row 6) times 15%. 13 =SUM(B10:B12) Total costs: sales personnel expenses (row 10) plus advertising (row 11) plus overhead (row 12). 15 =B8-B13 Product profit: gross margin (row 8) minus total costs (row 13). 16 =B15/B6 Profit margin: profit (row 15) divided by sales revenue (row 6). 18 Fixed values Product price. 19 Fixed values Product cost. This is a typical marketing model that shows sales rising from a base figure (perhaps due to the sales personnel) along with increases in advertising, but with diminishing returns. For example, the first \$5,000 of advertising in Q1 yields about 1,092 incremental units sold, but the next \$5,000 yields only about 775 units more.

Solving for a Value to Maximize Another Value One way you can use Solver is to determine the maximum value of a cell by changing another cell. The two cells must be related through the formulas on the worksheet. If they are not, changing the value in one cell will not change the value in the other cell. For example, in the sample worksheet, you want to know how much you need to spend on advertising to generate the maximum profit for the first quarter. You are interested in maximizing profit by changing advertising expenditures. You will see messages in the status bar as the problem is set up and Solver starts working. After a moment, you'll see a message that Solver has found a solution. Solver finds that Q1 advertising of \$17,093 yields the maximum profit \$15,093.
