Your break-even point is the moment you stop bleeding money. Before it, every sale reduces your losses. After it, every sale is pure profit.
The Formula
Break-Even Units = Fixed Costs ÷ (Price - Variable Cost per Unit)
Let's break that down:
- Fixed costs: Bills you pay regardless of sales (rent, software, insurance)
- Variable costs: Costs per unit sold (materials, shipping, payment fees)
- Price: What you charge per unit
Example: Coffee Shop
Fixed costs per month:
- Rent: £2,000
- Staff salaries: £3,000
- Insurance: £150
- Utilities: £350
- Total: £5,500
Per coffee:
- Price: £3.50
- Variable costs (beans, milk, cup): £0.80
- Contribution: £2.70
Break-even:
£5,500 ÷ £2.70 = 2,037 coffees per month
That's about 68 coffees per day (assuming 30 days open).
Why This Number Is Critical
Before break-even: You're losing money. Every coffee sale brings you £2.70 closer to breaking even, but you're still in the red overall.
After break-even: You're profitable. Coffee #2,038 of the month is your first coffee that's actually making you money.
Way below break-even: You might need to shut down, raise prices, or cut costs.
What Affects Your Break-Even Point
Raising prices lowers break-even
£4.00 coffee (£3.20 contribution) = 1,719 coffees needed (318 fewer)
Cutting fixed costs lowers break-even
Save £500/month on rent = 1,852 coffees needed (185 fewer)
Reducing variable costs lowers break-even
Better supplier (£0.65 per coffee) = 1,930 coffees needed (107 fewer)
Service Businesses & Break-Even
If you bill by the hour, treat each billable hour as a "unit."
Freelance designer:
- Fixed costs: £1,500/month (software, insurance, coworking space)
- Rate: £75/hour
- Variable cost: ~£5/hour (software licenses per project)
- Contribution: £70/hour
- Break-even: 21.4 hours per month
That's incredibly low—only about 5 hours per week. But this assumes 100% of your time is billable, which it's not. Realistically, 40-50% of your time is billable. So you'd need about 10-12 billable hours per week to break even.
The Danger Zone
If your break-even is more than 70% of your realistic sales capacity, you're in trouble.
Coffee shop example: If you can physically only sell 2,500 coffees per month, and you need 2,037 to break even, you only have 463 coffees' worth of profit potential (18.5% margin).
That's risky. A bad week wipes you out.
Reducing Break-Even Risk
1. Lower fixed costs (work from home, cheaper location)
2. Increase contribution margin (raise prices or cut variable costs)
3. Add high-margin products (pastries, merchandise)
4. Target volume-stable revenue (subscriptions, retainers)
The Bottom Line
Calculate your break-even point. If it's too high (>60-70% of capacity), your business model needs adjustment before you scale.
