Consider this formula:

      Breakeven point in units = Fixed costs ÷ contribution margin per unit

      If you sell a software application for $40, and variable costs are $20 (which just happens to be the same as in the trade-show example), each unit has a contribution margin of $20. If you have $1,000 in fixed costs, the formula looks like this:

       Breakeven point in units = $1,000 ÷ $20

       Breakeven point in units = 50

      If you sell 50 units, you’ve covered your fixed costs. Any sales over 50 units are all gravy and put you in Profit Land.

      Lowering the breakeven point to reach profitability sooner

      The lower the breakeven point, the easier it is to achieve your sales goal. It takes less effort to break even if you can lower the number of units you need to sell. Would you rather have to sell 100 units or 500 units just to break even? There’s a big difference in time, effort, and financial risk between 100 and 500 units. Think of less effort as taking less risk.

      You reduce your breakeven point by changing any one of its components, if you can (and that’s sometimes a big if). Here are some techniques, using the well-worn software application as an example.

      If you can change the costs or sales, you can reduce your breakeven point. To do so, make some changes to the earlier formula:

       Increasing the sale price to $45 per unit:Contribution margin per unit = $45 – $20Contribution margin per unit = $25Breakeven point in units = $1,000 ÷ $25Breakeven point in units = 40

       Reducing the variable cost to $15 per unit:Contribution margin per unit = $40 – $15Contribution margin per unit = $25Breakeven point in units = $1,000 ÷ $25Breakeven point in units = 40

       Reducing the fixed cost to $800 per unit:Contribution margin per unit = $40 – $20Contribution margin per unit = $20Breakeven point in units = $800 ÷ $20Breakeven point in units = 40

      In each case, you lowered the breakeven point in units to 40 units instead of 50. The result? It takes less selling effort — and requires less financial risk.

      Target net income: Setting the profit goal

      Target net income is the profit goal you set. (I use net income and profit to mean the same thing.)

      You compute target net income by plugging the figure into the breakeven formula — with one change. The profit changes from $0 to the target net income amount. Here’s the new formula:

      Target net income = sales – variable costs – fixed costs

      If you’re going to take that trip to the trade show, how much profit would make your trip worthwhile? How much profit could you produce if you decided not to go? Maybe that’s how you should answer the question. Assume your profit goal/target net income here is $2,000.

      Using the original information for sales, variable costs, and fixed costs, you can compute the sales you need to reach target net income:

       Target net income = sales – variable costs – fixed costs$2,000 = $40 × (units) – $20 × (units) – $1,000$3,000 = $20 × units)

       150 = $3,000 ÷ $20

      You’ll meet target net income by selling 150 units.

      

You need to sell 100 more units (150 units – 50 units) to increase your profit from breakeven to $2,000. You can think about your target net income in units or dollars.

      If you attend the trade show for three days, you need to average 50 sales per day to sell 150 units. If your booth is open for ten hours a day, you need to sell an average of five units per hour. Determine whether that’s reasonable. Is there enough interest in your product to reach that level of sales? That’s the real purpose of thinking through target net income.

      Lower profits and margin of safety

      The margin of safety is a cushion. If things don’t go as planned — if sales are lower than your budget — you need to know how low your total sales can go before you hit the breakeven point. The word margin, in this case, refers to the amount (in dollars or units) above the breakeven point.

      If actual sales were 30 units below your budget, your units sold would be 120 (150 – 30). You’re still way above your breakeven point of 50 units. The question always is if you don’t budget correctly, how far off can you be before your unit sales are below breakeven?

      Contribution margin versus gross margin

      Contribution margin represents the amount of money you have left after variable costs to cover fixed costs and keep for your profit. Gross margin explains how much of your sales proceeds are left after paying cost of sales.

      Cost of sales is the direct costs of creating your product. (See the direct and indirect cost section of Chapter 2.) If you were manufacturing denim jeans, you would have material costs for the denim and thread (and maybe a zipper), as well as the labor costs to sew the jeans. Your gross margin per pair of jeans sold might look like this:

       Gross margin = sale price – cost of sales (material and labor)

       Gross margin = $60 – $25

       Gross margin = $35

      Contribution margin (sales less variable costs) is part of the target net income formula. Try to avoid confusing the gross margin with contribution margin. The terms look similar, and both are thrown around in accounting conversations. Contribution margin is sales less variable costs. Gross margin, on the other hand, is sales less cost of sales.

      Using operating leverage

      The degree of operating leverage is a formula that shows how well you’re using your fixed costs to generate a profit. The more profit you can generate from the same amount of fixed cost, the higher your degree of operating leverage.

      Here’s the formula:

       Degree of operating leverage = contribution margin ÷ profit

       Profit = contribution margin – fixed costs

      First, calculate the contribution margin. Use the number of units from the target net income discussion above:

       Contribution margin = sales – variable costs

       Contribution margin = $40 × (150 units) – $20 × (150 units)

       Contribution margin = $20 × (150 units)

       Contribution margin = $3,000
