What is Break-Even Analysis?
Break-even analysis determines the point at which your business revenue equals your total costs—the moment you stop losing money and start making profit. It's one of the most important calculations for any business owner or investor.
At break-even:
- Profit = $0
- Revenue = Total Costs (Fixed + Variable)
The Break-Even Formula
There are two ways to calculate break-even:
Method 1: Break-Even in Units
Break-Even Units = Fixed Costs ÷ (Price per Unit - Variable Cost per Unit)
Also known as: Fixed Costs ÷ Contribution Margin per Unit
Method 2: Break-Even in Revenue
Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio
Contribution Margin Ratio = (Revenue - Variable Costs) ÷ Revenue
Understanding the Components
Fixed Costs
Expenses that don't change with sales volume:
- Rent/Lease payments
- Salaries (fixed employees)
- Insurance
- Loan payments
- Software subscriptions
- Utilities (base amount)
Variable Costs
Expenses that increase with each sale:
- Raw materials / COGS
- Commissions
- Credit card processing fees
- Shipping costs
- Packaging
- Hourly labor (production)
Contribution Margin
The amount each sale contributes toward covering fixed costs and generating profit:
- Per unit: Price - Variable Cost per Unit
- As ratio: (Price - Variable Cost) ÷ Price
Break-Even Example: Coffee Shop
Let's calculate break-even for a coffee shop. For a complete cafe feasibility analysis, see our cafe business plan guide.
Given Information:
| Monthly Fixed Costs | $8,000 |
| Average Price per Coffee | $5.00 |
| Variable Cost per Coffee | $1.50 (cup, coffee, milk, labor) |
| Contribution Margin per Unit | $5.00 - $1.50 = $3.50 |
Calculation:
Break-Even Units = $8,000 ÷ $3.50 = 2,286 coffees/month
Break-Even Revenue = 2,286 × $5.00 = $11,430/month
Interpretation:
The coffee shop needs to sell 2,286 coffees per month (about 76 per day) to break even. Any sales beyond this are profit.
Break-Even Example: E-commerce Business
Given Information:
| Monthly Fixed Costs | $5,000 (platform, hosting, salaries) |
| Average Order Value | $45.00 |
| Variable Costs per Order | $22.00 (product cost, shipping, fees) |
| Contribution Margin Ratio | ($45 - $22) ÷ $45 = 51% |
Calculation:
Break-Even Revenue = $5,000 ÷ 0.51 = $9,804/month
Break-Even Orders = $9,804 ÷ $45 = 218 orders/month
Break-Even Chart
A break-even chart visualizes the relationship between costs, revenue, and profit:
| Units Sold | Revenue | Total Costs | Profit/Loss |
|---|---|---|---|
| 0 | $0 | $8,000 | -$8,000 |
| 1,000 | $5,000 | $9,500 | -$4,500 |
| 2,000 | $10,000 | $11,000 | -$1,000 |
| 2,286 | $11,430 | $11,429 | $0 (Break-Even) |
| 3,000 | $15,000 | $12,500 | +$2,500 |
| 4,000 | $20,000 | $14,000 | +$6,000 |
Advanced: Break-Even with Multiple Products
When you sell multiple products, calculate a weighted average contribution margin:
| Product | Price | Variable Cost | CM | Sales Mix | Weighted CM |
|---|---|---|---|---|---|
| Coffee | $5.00 | $1.50 | $3.50 | 60% | $2.10 |
| Pastry | $4.00 | $1.00 | $3.00 | 30% | $0.90 |
| Sandwich | $8.00 | $3.00 | $5.00 | 10% | $0.50 |
| Weighted Average CM | $3.50 | ||||
Use the weighted average CM in your break-even formula.
Break-Even Time Period
Beyond monthly break-even, calculate how long until you recover your initial investment:
Break-Even Time = Initial Investment ÷ Monthly Profit After Break-Even
Example:
- Initial Investment: $100,000
- Monthly Revenue: $25,000
- Monthly Costs: $20,000
- Monthly Profit: $5,000
- Break-Even Time = $100,000 ÷ $5,000 = 20 months
Common Mistakes
- Mixing fixed and variable costs: Misclassifying costs leads to wrong calculations
- Ignoring semi-variable costs: Some costs (like utilities) have both fixed and variable components
- Using gross margin instead of contribution margin: These are different metrics
- Forgetting to include all fixed costs: Owner salary, depreciation, loan payments
- Assuming linear relationships: At high volumes, costs per unit may change

Pricing Decisions
If you raise prices by 10%, how does break-even change? Lower break-even = lower risk.
Cost Reduction
Reducing variable costs increases contribution margin and lowers break-even.
Expansion Planning
Adding fixed costs (new location, more staff) requires higher break-even. Is the market there?
Risk Assessment
If break-even is 80% of your capacity, you have little margin for error. If it's 40%, you have room to weather slow periods.
