Break-even is the point at which your business generates exactly enough revenue to cover all its costs — and zero profit. Every euro of revenue after that point contributes to profit. Understanding your break-even is foundational for pricing decisions, financial projections, and knowing when your business model actually works.
Fixed vs Variable Costs
Before calculating break-even, you need to separate costs into two types:
- Office rent, salaries, insurance, software subscriptions, loan repayments
- In Luxembourg: expect fixed costs of €15,000–€40,000/month for a small team
- Cost of goods sold (COGS), transaction fees, shipping, commissions
- Expressed as a percentage of revenue or per unit
The Break-Even Formula
Break-even revenue = Fixed costs ÷ Gross margin percentage
If your fixed costs are €20,000/month and your gross margin is 60%: Break-even = €20,000 ÷ 0.60 = €33,333/month in revenue
This means you need to generate €33,333 in monthly revenue before you make a single euro of profit.
Break-even units = Fixed costs ÷ (Price per unit − Variable cost per unit)
If you sell a product at €100 with €40 variable cost and €20,000 fixed costs: Break-even = €20,000 ÷ (€100 − €40) = 333 units/month
Margin of Safety
Once you know break-even, calculate your margin of safety:
Margin of safety = (Actual revenue − Break-even revenue) ÷ Actual revenue × 100
If you're generating €50,000 and break-even is €33,333: Margin of safety = (€50,000 − €33,333) ÷ €50,000 = 33.3%
This means revenue can drop by 33% before you start losing money. Healthy businesses typically target a 20–40% margin of safety.
Improving Your Break-Even Position
- Raise prices: if demand allows, even a 10% price increase dramatically improves break-even
- Reduce variable costs: renegotiate supplier contracts, improve operational efficiency
- Reduce fixed costs: remote work, shared office, renegotiating software contracts
- Increase gross margin: move up the value chain, productise services
