Cheat Sheet
- Reading the Contribution Margin Income Statement -
This handy format uses contribution margin income statements to organize costs by behavior, listing sales, variable costs, and fixed costs before arriving at operating income. For example, if sales are $100,000 and variable costs are $60,000, the contribution margin is $40,000, clearly showing how much revenue contributes to covering fixed costs and profit.

- Classifying Costs with the y = a + bx Model -
Pro tip: use the equation y = a + bx to organize costs by behavior - where "a" is total fixed cost and "b" is variable cost per unit times activity level x. For instance, if fixed costs (a) are $500 and variable cost per unit (b) is $5 at 100 units, total cost y = 500 + 5×100 = $1,000. (Source: Harvard Business School Online)
- Calculating Contribution Margin & Ratio -
Quick trick: contribution margin equals Sales minus Variable Costs, and the contribution margin ratio is Contribution Margin ÷ Sales. If your contribution margin is $40,000 on $100,000 in sales, the ratio is 40%, showing each sales dollar contributes $0.40 toward fixed costs and profit. (Source: Institute of Management Accountants)
- Break-even & Target Profit Analysis -
Break-even in units = Fixed Costs ÷ Contribution Margin per Unit; break-even in dollars = Fixed Costs ÷ Contribution Margin Ratio. For example, with fixed costs of $20,000 and a $10 contribution margin per unit, you need 2,000 units to break even. To hit a target profit, simply add desired profit to fixed costs in the numerator.

- Estimating Costs via the High-Low Method -
This simple approach finds variable cost per unit by dividing the cost difference between high and low activity levels by the change in units. For example, if costs are $18,000 at 3,000 units and $12,000 at 1,000 units, variable cost = ($18,000 - $12,000)/(3,000 - 1,000) = $3 per unit. Then calculate fixed cost by subtracting total variable cost at either activity level from total cost. (Source: Journal of Cost Analysis & Management)
