How to Calculate Break-even Point

Introduction

Break-even is the point where revenue equals costs—you’re not making money, but you’re not losing it either. Knowing it helps you set targets and see how many sales or hours you need to cover expenses.

Before you can grow or invest, you need to know the minimum you must earn to cover your fixed and variable costs. That minimum is your break-even point. For freelancers it often translates to “how many billable hours do I need this month?” or “how much revenue do I need to cover my overhead?” Once you know that number, you can set goals above it and use a break-even calculator to test how changes in price or cost affect the result.

We'll define break-even, explain why it matters for planning and pricing, and show how to calculate it for your business. Use the break-even calculator on this site to plug in your numbers.

What It Is

The break-even point is the level of sales (or hours, or units) at which total revenue equals total costs. Below that, you lose money; above it, you make profit. For freelancers it’s often expressed as “how much revenue (or how many billable hours) do I need to cover fixed and variable costs?”

Fixed costs don’t change with output (rent, insurance, software, base pay). Variable costs do (materials per unit, subcontractors per project). Contribution margin is price minus variable cost per unit—the amount each sale contributes toward covering fixed costs. Break-even units = fixed costs ÷ contribution per unit; break-even revenue = break-even units × price. For service businesses, “units” can be billable hours and “price” your hourly rate.

Why It Matters

Break-even tells you the minimum you need to survive. It’s useful for planning (e.g. “I need 3 projects this quarter to break even”) and for pricing (you must charge above your cost per unit or hour to ever reach profit).

How to Calculate It

Break-even revenue = Fixed costs ÷ (1 − (Variable costs ÷ Revenue per unit)). Or for simplicity: Break-even = Fixed costs ÷ Contribution margin per unit, where contribution margin = Price − Variable cost per unit. For a freelancer: Fixed costs (monthly) ÷ (Hourly rate − Variable cost per hour) = billable hours needed to break even. Then add the hours (or revenue) you need for desired profit.
Example: break-even hours = fixed costs ÷ (hourly rate − variable cost per hour).Fixed costs ($/mo) Rate ($/hr) Variable ($/hr) Contribution ($/hr) Break-even hours
4,000 100 20 80 50

Example: break-even hours = fixed costs ÷ (hourly rate − variable cost per hour).
Fixed costs ($/mo)	Rate ($/hr)	Variable ($/hr)	Contribution ($/hr)	Break-even hours
4,000	100	20	80	50

Real-Life Example

A consultant has $4,000/month fixed costs. Her effective rate is $100/hour and variable cost per billable hour (e.g. subcontractors, tools per project) is $20. Contribution per hour = $80. Break-even hours = $4,000 ÷ $80 = 50 hours per month. So she needs 50 billable hours just to cover costs; anything above is profit.

Common Mistakes

Forgetting some fixed costs (insurance, software, your salary floor). Using revenue instead of contribution margin. Not updating when costs or rates change. Treating break-even as a target instead of a floor.

Practical Tips

List all fixed costs first. Then work out variable cost per unit (or per hour). Use the formula to get break-even units or revenue. Revisit when you change prices or costs. Aim above break-even for profit.

FAQs

Fixed costs don’t change with output (rent, insurance, base software). Variable costs do (materials per project, subcontractors, commissions). Some costs are mixed; split them for the calculator.

For break-even, include the minimum you need to pay yourself (or draw) to keep going. That way break-even reflects “can I sustain this?” not just “can I cover rent and software?”

If your variable cost per hour is high, you need a higher rate to have enough contribution to cover fixed costs in fewer hours. Break-even helps you see that link and test different rates.

If variable cost per unit is greater than price, you can’t break even at that price—you lose money on every unit. You must raise price or lower variable cost before you can reach break-even.

Whenever you change fixed costs, price, or variable cost. At least once a year is good practice. After adding a big fixed cost (e.g. hire, new office), recalculate right away to see your new minimum.

Conclusion

Break-even is a useful minimum. Calculate it once, update when things change, and use it to set revenue and pricing targets.

Use a break-even calculator to enter your fixed costs, price per unit (or hour), and variable cost per unit. The tool will show break-even units and revenue. Set your monthly or quarterly target above that number so you’re profitable, and revisit the calculation when you add fixed costs (e.g. new software or an employee) or change your rate.
