Every business has a point at which total revenue finally equals total costs — the moment it stops losing money and starts making it. That point is the break-even point, and knowing exactly where it sits is one of the most important insights any business owner can have.
Too many businesses operate without knowing their break-even number. They price products based on gut feel, set sales targets arbitrarily, and make expansion decisions without understanding how many units they truly need to sell to justify the investment.
This free break-even calculator gives you your break-even in both units and revenue, your contribution margin per unit, and how many units you need to sell to hit any profit target — not just zero.

What Is a Break-Even Calculator (Free) – Find Your Break-Even Point in Units & Revenue?
Break-even analysis is a financial calculation that identifies the sales volume at which total revenue exactly equals total costs. Above the break-even point, every additional unit sold generates profit. Below it, every unit sold brings a loss.
The central concept is the Contribution Margin — the amount left over from each sale after covering the variable costs of production. This contribution first covers fixed costs, and once fixed costs are covered, every additional unit’s contribution becomes pure profit:
- Fixed Costs — costs that stay constant regardless of how many units you sell: rent, salaries, insurance, software subscriptions
- Variable Costs — costs that change with each unit produced: materials, packaging, shipping, direct labour, sales commission
- Contribution Margin = Selling Price − Variable Cost Per Unit
Formula
Break-even analysis uses contribution margin to calculate the exact sales volume needed:
Contribution Margin Per Unit = Selling Price − Variable Cost Per Unit Contribution Margin Ratio = Contribution Margin ÷ Selling Price Break-Even Units = Fixed Costs ÷ Contribution Margin Per Unit Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio Units for Profit Target = (Fixed Costs + Profit Target) ÷ Contribution Margin Per Unit
Example Calculation
A small product business with $20,000 monthly fixed costs, a $150 selling price, and $60 variable cost per unit:
| Selling price per unit | $150.00 |
| Variable cost per unit | $60.00 |
| Contribution margin per unit | $90.00 |
| Contribution margin ratio | 60% |
| Monthly fixed costs | $20,000 |
| Break-Even Units (monthly) | 223 units |
| Break-Even Revenue | $33,333 |
| Units to earn $10K profit | 334 units |
What Is a Good Result?
Healthy contribution margin ratios by industry type:
| Business type | Cm ratio | Signal |
|---|---|---|
| Physical product retail | 30–50% | High volume needed to cover fixed base |
| Food service / hospitality | 60–75% | Strong CM but very high fixed cost base |
| Software / SaaS | 70–85% | Excellent CM — fixed cost leverage is massive at scale |
| Professional services | 50–75% | Labour-intensive — variable costs dominate |
| Manufacturing | 25–45% | Capital-intensive — high break-even threshold |
How to Improve Your Results
Use Break-Even to Test Your Pricing Strategy
Run break-even for multiple price points before finalising. **A 20% price increase on a 50% CM product only increases break-even units by 13%** — but generates dramatically more profit per unit. The calculator makes this trade-off instantly visible.
Every Fixed Cost Reduction Directly Lowers Break-Even
Moving from $25,000 to $20,000 in monthly fixed costs on a $90 CM product **reduces break-even units by 56** — immediately. Negotiating a better lease, cutting unused software, or reducing contracted services has a direct and mathematically precise impact on your minimum viable sales volume.
Calculate Break-Even by Product, Not Just Business
If you sell multiple products with different contribution margins, your actual break-even depends on your **sales mix**. Products with high CM should receive more shelf space, marketing budget, and sales focus — they cover fixed costs fastest and generate the most profit per unit sold.
Include Your Own Salary in Fixed Costs
Business owners who don't pay themselves a market-rate salary are creating a **false picture of break-even**. Your time has a cost. Including a reasonable owner's salary in fixed costs gives you an honest break-even that accounts for the full cost of running the business.
Recalculate Break-Even When Costs Change
Supplier price increases, new hires, rent rises, and pricing changes all shift your break-even. **Quarterly recalculation** ensures your sales targets remain grounded in current economics, not the numbers from when you first started.
Frequently Asked Questions
1How do I calculate the break-even point?
**Break-Even Units = Fixed Costs ÷ (Selling Price − Variable Cost Per Unit)**. The denominator is the contribution margin per unit. For example: $20,000 monthly fixed costs ÷ ($150 selling price − $60 variable cost) = $20,000 ÷ $90 = **223 units per month** to break even.
2What is contribution margin and why does it matter?
**Contribution Margin = Selling Price − Variable Cost Per Unit**. It’s the amount each unit sold contributes toward covering fixed costs — and then, once fixed costs are covered, toward profit. A higher contribution margin means fewer units are needed to break even and profit builds faster after break-even is reached.
3Can I calculate break-even for a service business?
Yes. For service businesses, replace ‘variable cost per unit’ with the **direct cost of delivering each service** (hourly labour, materials, travel). Fixed costs remain the same (office, software, admin staff). The contribution margin is then the per-job margin after direct delivery costs, and break-even is the number of jobs or clients needed to cover overheads.
4What if my selling price is below my variable cost per unit?
If your variable cost exceeds your selling price, your **contribution margin is negative** — you lose money on every unit sold, and no sales volume will make the business viable. This is the most critical output of break-even analysis: it immediately reveals whether a business model is structurally viable before you invest further.
Conclusion
Knowing your break-even point transforms vague ‘we need to sell more’ thinking into a precise, actionable sales target. Use the free break-even calculator above to find your number — then use it to price correctly, set realistic targets, and make expansion decisions with financial clarity.
