Small Business Break-Even Calculator
Find out how many units you need to sell each month to cover your costs.
What does "break-even" actually mean?
Your break-even point is the number of units you need to sell in a given period — here, a month — for your total revenue to exactly equal your total costs, with zero profit and zero loss. Every unit sold beyond that point contributes directly to profit, while every unit short of it means the business is still operating at a loss for that period. It's one of the most fundamental numbers in small business planning because it translates abstract costs into a concrete, trackable sales target.
What is contribution margin and why does it drive everything here?
Contribution margin is simply your price per unit minus your variable cost per unit — the amount each sale actually contributes toward covering your fixed costs before any profit begins. A higher contribution margin means fewer units are needed to break even, which is why pricing strategy and controlling variable costs (materials, shipping, per-unit labor) have such an outsized effect on how quickly a business becomes sustainable. If your price doesn't exceed your variable cost, no volume of sales will ever get you to break-even — you'd lose more money with every unit sold.
How should I use this number in real planning?
Once you know your break-even units, compare it honestly against your realistic monthly sales capacity — if break-even requires selling far more units than you can realistically produce, market, or fulfill, the underlying price or cost structure likely needs to change before the business can work. Many small business owners also use this calculator to stress-test decisions like raising prices, negotiating lower material costs, or cutting a recurring fixed expense, since each of those levers shifts the break-even point in a very visible, quantifiable way.
Frequently Asked Questions
What is the break-even point?
It's the number of units you need to sell so that total revenue exactly equals total costs — no profit, no loss. Selling more than that number puts you in profit; selling fewer means you're still operating at a loss for that period.
What is contribution margin?
Contribution margin is your price per unit minus your variable cost per unit — the amount each individual sale contributes toward covering your fixed costs before any profit is realized. A higher contribution margin means you reach break-even with fewer sales.
What if my variable cost is higher than my price?
If your price doesn't exceed your variable cost per unit, you have a negative contribution margin, meaning you lose money on every single sale regardless of volume — no amount of sales will ever reach break-even. You'd need to raise your price, lower your variable costs, or both before the product can become viable.
What counts as a fixed cost versus a variable cost?
Fixed costs stay roughly the same regardless of how much you sell, like rent, salaries, and insurance. Variable costs scale directly with each unit sold, like materials, packaging, and per-unit shipping. Break-even analysis depends on separating these two correctly.
How can I lower my break-even point?
You can raise your price, reduce your variable cost per unit (better supplier terms, more efficient production), or cut your fixed costs. Any of these increases your contribution margin or reduces total costs, both of which lower the number of units needed to break even.
Is break-even analysis useful for service businesses, not just products?
Yes — you can treat a billable hour, a client engagement, or a subscription seat as your "unit" and apply the same logic: price per unit minus variable cost per unit gives your contribution margin, which determines how many you need to sell to cover fixed costs.
Does break-even analysis account for taxes?
No, this calculator focuses purely on the operational break-even point before taxes. Taxes are typically applied to profit after you've already crossed break-even, so they don't factor into the units-needed calculation itself.
Should a new business expect to hit break-even immediately?
Not usually — many new businesses take months or longer to reach consistent break-even sales volume while building awareness and customer base. This calculator is most useful as an ongoing planning tool to track progress toward that target and evaluate pricing or cost changes along the way.
