What is the break-even point?
Your break-even point is the number of units you must sell to cover all your costs — the moment you stop losing money and start making it. Below it you're in the red; above it, every additional sale is profit.
Break-even units = Fixed costs ÷ (Price per unit − Variable cost per unit)
With $10,000 in fixed costs, a $50 price, and $30 variable cost per unit, you break even at $10,000 ÷ ($50 − $30) = 500 units, or $25,000 in revenue.
How to calculate break-even (step by step)
- Sum your fixed costs — rent, salaries, software subscriptions, insurance. Everything that doesn't change with sales volume.
- Determine your variable cost per unit — materials, packaging, shipping, transaction fees. What each additional sale costs you.
- Calculate contribution margin per unit = Price − Variable cost per unit.
- Divide fixed costs by contribution margin — the result is your break-even point in units.
- Multiply by price — that's your break-even revenue.
Worked example: contribution margin building to break-even
A small DTC brand with the following economics:
| Input | Value |
|---|---|
| Fixed costs (monthly) | $12,000 |
| Price per unit | $60 |
| Variable cost per unit | $24 |
| Contribution margin per unit | $36 |
| Break-even units | 334 units |
| Break-even revenue | $20,040 |
Now watch how contribution margin accumulates as sales grow:
| Units sold | Total contribution | Cumulative vs fixed costs | Status |
|---|---|---|---|
| 100 | $3,600 | −$8,400 | Still in the red |
| 200 | $7,200 | −$4,800 | Approaching break-even |
| 300 | $10,800 | −$1,200 | Almost there |
| 334 | $12,024 | $0 | Break-even reached |
| 400 | $14,400 | +$2,400 | Now in profit |
| 500 | $18,000 | +$6,000 | Each unit past 334 is pure profit |
Every unit sold past 334 drops $36 of contribution margin straight to the bottom line. Before 334, you haven't yet covered rent and salaries. This is why the break-even point is the most important volume target in any business — it's the minimum viable scale.
What-if: price change impact
Raise the price from $60 to $70 (variable cost stays $24):
| Change | Before | After |
|---|---|---|
| Contribution margin per unit | $36 | $46 |
| Break-even units | 334 | 261 |
| Break-even revenue | $20,040 | $18,270 |
A $10 price increase drops the break-even point by 22% — 73 fewer units to cover the same fixed costs. That's why pricing is often the highest-leverage business decision.
The key idea: contribution margin
The denominator — price minus variable cost — is your contribution margin per unit: the slice of each sale left over to cover fixed costs. At $36 per unit here, it takes 334 units to cover $12,000 of fixed costs. Raise your price or cut variable costs and the contribution margin grows, so you break even sooner. If price is below variable cost, contribution is negative and you can never break even no matter how much you sell — the calculator will flag this.
Why break-even analysis matters
Break-even analysis tells you the minimum viable scale of a product, campaign, or whole business. It answers questions like: "Can this product ever pay for itself?" "How many units do I need to sell before I can quit my day job?" "Does this marketing campaign generate enough volume to cover its own cost?"
Pair it with your profit margin to set realistic sales targets, your marketing budget to decide how much ad spend is affordable, and the contribution margin calculator to drill into the variable vs fixed cost split.
The benchmarks table below serves two purposes: the top rows show contribution margins by industry (use these to calibrate your price and cost inputs), and the bottom rows show typical break-even timelines (the time dimension — how long businesses in those industries usually take to reach profitability). Your calculator results give the volume dimension: exactly how many units and how much revenue you need. Together they tell you whether the numbers are achievable in your market.
