The break-even point is the level of sales (in units or dollars) at which total revenue equals total costs — no profit, no loss. Break-Even Point = Fixed Costs / (Price - Variable Cost per Unit). Break-Even Units = Fixed Costs ÷ Contribution Margin (where Contribution Margin = Price - Variable Cost). Contribution margin is the amount each unit contributes toward covering fixed costs and profit.

Break-Even Point = Fixed Costs / (Price - Variable Cost per Unit). It's the minimum sales needed to cover ALL costs — no profit, no loss. A pizza shop with $120K in fixed costs selling $15 pizzas with $5 variable cost needs to sell 12,000 pizzas (or $180K revenue) just to break even. The contribution margin ($10/pizza) determines how fast you reach break-even. Margin of Safety = (Actual Sales - Break-Even Sales) / Actual Sales — if it's under 20%, you're vulnerable to downturns. 60% of startups fail because they never reach break-even.
📈 By the Numbers
📋 Key Takeaways
- • Break-Even Units = Fixed Costs ÷ (Price - Variable Cost)
- • Contribution Margin = Price - Variable Cost — each unit's contribution to fixed costs
- • Margin of Safety = (Actual - Break-Even) / Actual — under 20% is risky
- • Higher contribution margin = lower break-even point
📐 How It Works
- Break-Even Formula: Fixed Costs ÷ (Price - Variable Cost). The denominator is contribution margin.
- Break-Even Sales: Break-Even Units × Price. Total revenue needed to cover all costs.
- Contribution Margin: Each unit contributes this amount toward fixed costs first; above break-even, it becomes profit.
- Multi-Product: Use weighted average contribution margin based on sales mix. Break-Even = Fixed Costs ÷ Weighted Avg CM.
💡 Expert Tips
- Focus on contribution margin, not just volume.
- Price increases have 3× the impact of cost cuts on break-even.
- Track your margin of safety — it's your cushion against downturns.
- Fixed vs variable classification matters — get it right.

❓ Frequently Asked Questions
What is the break-even point?
The break-even point is the level of sales (in units or dollars) at which total revenue equals total costs — no profit, no loss. It's the minimum sales needed to cover ALL costs. Below break-even you lose money; above it, every additional sale contributes to profit.
What is the break-even formula?
Break-Even Point = Fixed Costs / (Price - Variable Cost per Unit). Break-Even Sales = Break-Even Units × Price. The denominator (Price - Variable Cost) is the contribution margin — the amount each unit contributes toward covering fixed costs and profit.
How do I calculate break-even in units and dollars?
Break-Even Units = Fixed Costs ÷ Contribution Margin (where Contribution Margin = Price - Variable Cost). Break-Even Sales = Break-Even Units × Price. Example: $120K fixed, $15 price, $5 variable → CM $10 → 12,000 units to break even, $180K in revenue.
What is contribution margin and why does it matter?
Contribution margin is the amount each unit contributes toward covering fixed costs and profit. It equals Price minus Variable Cost. Higher contribution margin means fewer units needed to break even. A pizza with $15 price and $5 variable cost has $10 contribution margin — every pizza sold covers $10 of fixed costs.
What does a break-even chart show?
A break-even chart plots revenue and total costs against units sold. The two lines intersect at the break-even point. Below that point you're in the loss zone; above it, the profit zone. The steeper the revenue line (higher contribution margin), the sooner you reach break-even.
What is margin of safety?
Margin of Safety = (Actual Sales - Break-Even Sales) / Actual Sales. It measures how far your current sales are above break-even — your cushion against downturns. If it's under 20%, you're vulnerable. A 33% margin of safety means you can absorb a 33% sales drop before losing money.
