Break-Even Analysis Explained

How to calculate when your business starts making money

What Is Break-Even Analysis?

Break-even analysis tells you exactly how much you need to sell before your business starts making a profit. Below the break-even point, every sale reduces your losses. Above it, every sale is profit. It's the most fundamental planning tool for any business.

The Formula

Break-Even Units = Fixed Costs ÷ (Price Per Unit − Variable Cost Per Unit)

The denominator — price minus variable cost — is called the contribution margin. It's how much each sale contributes toward covering your fixed costs.

Example — Coffee Shop
Fixed costs: $8,000/month (rent, insurance, salaries, utilities)
Price per coffee: $5.00
Variable cost per coffee: $1.50 (beans, cup, lid, milk)
Contribution margin: $5.00 − $1.50 = $3.50
Break-even: $8,000 ÷ $3.50 = 2,286 coffees/month (about 76/day)

Every coffee beyond 2,286 generates $3.50 in profit.

How to Lower Your Break-Even Point

Using Break-Even for Pricing

Before setting a price, run break-even at several price points. If your break-even at $50 is 200 units/month, ask yourself: "Can I realistically sell 200 units?" If not, you need a higher price or lower costs. This prevents the common mistake of pricing too low and never reaching profitability.

Frequently Asked Questions

How long should it take to break even?
Service businesses: 3–6 months. Retail: 6–18 months. Restaurants: 12–24 months. Tech startups: often 2–5 years. The timeline depends on your industry, fixed costs, and how quickly you can build revenue.
What if I sell multiple products?
Use a weighted average contribution margin based on your product mix. Or calculate break-even in revenue dollars instead of units: Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio (where ratio = average contribution margin ÷ average selling price).
