What Is the Break-Even Point?
The break-even point is the level of sales at which total revenue exactly equals total cost, producing neither profit nor loss. Below it a business loses money; above it, every additional sale contributes to profit.
What the break-even point is and why it matters
Break-even analysis separates costs into fixed (rent, salaries, insurance — unchanged by volume) and variable (materials, per-unit labor — rising with each unit). The break-even point is where the contribution from sales finally covers all fixed costs. It's a core planning tool: it tells an owner the minimum sales needed to survive, how pricing or cost changes shift that threshold, and how much cushion current sales provide. For advisory-minded accounting firms, walking a client through break-even is a high-value conversation.
A worked example
A company has fixed costs of $50,000 per month. Each unit sells for $100 and costs $60 in variable costs, giving a contribution margin of $40 per unit. Break-even in units = fixed costs ÷ contribution margin = $50,000 ÷ $40 = 1,250 units per month. In dollars, that's 1,250 × $100 = $125,000 in sales. Selling 1,300 units produces a $2,000 profit (50 extra units × $40); selling 1,200 produces a $2,000 loss.
How firms handle it today
Firms build break-even models in spreadsheets from the client's cost structure, updating fixed and variable assumptions to answer "what if" pricing and volume questions during advisory work.

FAQ
What is the break-even formula?
Break-even units = fixed costs ÷ (price per unit − variable cost per unit), where the denominator is the contribution margin.
Why is the break-even point useful?
It shows the minimum sales needed to avoid a loss and how pricing or cost changes affect profitability.
What's the difference between fixed and variable costs?
Fixed costs stay the same regardless of volume; variable costs rise and fall with the number of units produced or sold.
