Calculate exactly how many units you need to sell — and how much revenue you need to bring in — before your business starts turning a profit.
Quick Answer
Your break-even point is the sales volume at which total revenue equals total costs — the point where you stop losing money and start making a profit. It’s calculated as Break-Even Units = Fixed Costs ÷ (Selling Price per Unit − Variable Cost per Unit). Enter your fixed costs, variable cost per unit, and selling price into the calculator above to get your exact break-even point in units and dollars.

Every business — whether it sells physical products, offers services, or runs on a subscription model — has a single number that separates loss from profit: the break-even point. It’s the sales volume at which your revenue exactly covers your costs, with nothing left over and nothing owed. Below that number, you’re operating at a loss. Above it, every additional sale adds to your profit. The break-even calculator on this page does the math for you using your fixed costs, variable cost per unit, and selling price per unit, returning your break-even point in both units and dollars, along with your contribution margin. The sections below explain what break-even analysis means, how the formula works, how to read your results, and how to use break-even thinking to make smarter pricing and cost decisions.
What Is a Break-Even Point?
The break-even point is the level of sales — measured in units sold or dollars of revenue — at which total revenue equals total costs. At this exact point, a business has neither a profit nor a loss; it has simply covered everything it spent to operate and produce. Sell one more unit past break-even, and that sale contributes directly to profit. Sell fewer units than your break-even point, and the business is operating at a loss, even if revenue looks healthy on paper.
Break-even analysis is one of the oldest and most widely used tools in managerial accounting because it connects three variables that every business owner already tracks — fixed costs, variable costs, and selling price — into a single, actionable number: how much do I need to sell before I start making money?
How to Use the Break-Even Calculator
The calculator above asks for three inputs, all specific to your product or service:
Once you enter these three numbers, the calculator instantly returns your contribution margin per unit, your contribution margin ratio, your break-even point in units, and your break-even point in revenue dollars.
Break-Even Formula
The break-even calculator uses the standard contribution-margin method, the same approach taught in accounting and business courses worldwide:
Break-Even Units = Fixed Costs ÷ Contribution Margin
Break-Even Revenue = Break-Even Units × Selling Price per Unit
The calculator also reports a fourth figure, the Contribution Margin Ratio, which expresses contribution margin as a percentage of selling price: Contribution Margin Ratio = (Contribution Margin ÷ Selling Price) × 100. This is useful for comparing profitability across products with very different price points.
Break-even analysis only works when the contribution margin is positive — meaning your selling price is higher than your variable cost per unit. If variable cost per unit equals or exceeds selling price, there is no volume of sales, however large, that will let you break even; every unit sold adds to the loss instead of reducing it.
Break-Even Calculator Example
Suppose a small business has $10,000 in fixed costs per month, sells its product for $50 per unit, and spends $30 per unit on materials and labor:
| Metric | Value |
|---|---|
| Fixed Costs | $10,000 |
| Selling Price per Unit | $50 |
| Variable Cost per Unit | $30 |
| Contribution Margin | $50 − $30 = $20 |
| Break-Even Units | $10,000 ÷ $20 = 500 units |
| Break-Even Revenue | 500 × $50 = $25,000 |
This business needs to sell 500 units, generating $25,000 in revenue, before it covers all its fixed and variable costs. Its 501st sale is the first dollar of profit. This is an illustrative example using round numbers for clarity.
For comparison, the calculator’s own default inputs — $10,000 fixed costs, $25 variable cost per unit, $50 selling price — produce a contribution margin of $25 (a 50% contribution margin ratio), a break-even point of 400 units, and break-even revenue of $20,000. This is what you’ll see pre-filled the first time you open the calculator above; the figures are illustrative starting values, not a recommendation for any specific business.
Why Is Break-Even Analysis Important?
Break-even analysis turns abstract cost and pricing decisions into a concrete sales target. It tells you the minimum volume you must hit to avoid losing money, which makes it a foundational input for pricing strategy, budgeting, loan applications, and go/no-go decisions on new products. A business that knows its break-even point can answer questions like “can we afford to discount this product by 10%?” or “how many units do we need to sell this quarter just to survive?” with a specific number instead of a guess.
Lenders and investors frequently ask for break-even analysis as part of a business plan because it demonstrates that the founder understands the relationship between costs, pricing, and volume — and shows how much runway or sales growth is needed before the business becomes self-sustaining.
Break-Even Point vs. Profit
Break-even and profit are related but distinct concepts. The break-even point is the specific sales volume where profit equals exactly zero — total revenue matches total costs precisely. Profit is what happens on either side of that point: a loss below break-even, and positive profit above it. Every unit sold beyond the break-even point contributes its full contribution margin (selling price minus variable cost) directly to profit, since fixed costs have already been fully covered.
This is why break-even analysis is often paired with a “margin of safety” calculation — the gap between current or projected sales and the break-even point — to show how much of a sales decline a business could absorb before slipping back into a loss.
Fixed Costs vs. Variable Costs
Getting your break-even number right depends entirely on correctly classifying your costs as fixed or variable.
Fixed costs stay the same regardless of how many units you sell:
- Rent or lease payments
- Salaried employee wages
- Insurance premiums
- Software and subscription costs
- Loan payments and depreciation
Variable costs rise and fall directly with sales or production volume:
- Raw materials and components
- Direct, hourly production labor
- Packaging
- Shipping and fulfillment
- Payment processing fees per transaction
Some costs are “semi-variable” — a cell phone plan with a base fee plus per-minute charges, for example — and need to be split into their fixed and variable components before running a break-even calculation.
What Is Contribution Margin?
Contribution margin is the amount left over from each sale after variable costs are subtracted from the selling price — the amount each unit “contributes” toward covering fixed costs and, eventually, profit. It’s the single most important number in break-even analysis, because it directly determines how many units you need to sell.
The contribution margin ratio (contribution margin expressed as a percentage of selling price) is especially useful when comparing products at different price points, or when deciding which product to prioritize promoting: a higher contribution margin ratio means more of every sales dollar goes toward profit.
What Can Change Your Break-Even Point?
Your break-even point isn’t fixed forever — it shifts whenever any of the following change:
- Selling price — raising price increases contribution margin and lowers break-even units.
- Variable cost per unit — cheaper materials or labor increases contribution margin.
- Fixed costs — a rent increase, a new hire, or a new software subscription raises break-even volume.
- Product mix — businesses selling multiple products see their blended break-even shift as the sales mix shifts toward higher- or lower-margin items.
- Discounts and promotions — temporary price cuts raise the break-even volume needed to hit the same profit target.
- Economies of scale — bulk purchasing or process efficiencies can lower variable cost per unit as volume grows.
How to Lower Your Break-Even Point
A lower break-even point means less risk and a shorter runway to profitability. There are three fundamental levers:
- Increase selling price — directly increases contribution margin per unit.
- Reduce variable cost per unit — negotiate better supplier terms, reduce waste, or find lower-cost materials.
- Reduce fixed costs — renegotiate rent, cut unused subscriptions, or move to a more efficient operating structure.
A caveat on raising prices: the break-even formula assumes sales volume stays constant when price changes, but in reality, demand is elastic — raising price can reduce the number of units customers are willing to buy. A price increase that improves your contribution margin on paper can still hurt total profit if it drives away enough volume. Any pricing decision should be paired with a realistic estimate of how demand will respond, not just the break-even math in isolation.
Who Can Use a Break-Even Calculator?
Break-even analysis applies to almost any revenue-generating operation. Common users include:
- Startup founders building a business plan or pitch deck
- Small business owners setting or adjusting prices
- E-commerce sellers evaluating a new product line
- Restaurant and café owners pricing menu items
- Freelancers and consultants setting hourly or project rates
- Manufacturers deciding on production volume
- Retailers planning inventory purchases
- Nonprofit organizations pricing tickets or program fees to cover costs
- Financial analysts and accountants preparing business projections
- Students and educators learning managerial accounting concepts
Break-Even Analysis for Service Businesses
Service businesses — consultants, agencies, salons, gyms — don’t sell physical units, but the same math applies if you treat “an hour of service,” “a client,” or “a membership” as your unit. Fixed costs are still rent, salaries, and software; variable costs might be minimal (a consultant with low per-client cost) or more significant (a salon buying product per appointment).
Example: A freelance consultant has $4,000/month in fixed costs (software, insurance, workspace) and negligible variable cost per session. Charging $200 per one-hour session, contribution margin is essentially $200. Break-even is $4,000 ÷ $200 = 20 sessions per month. This is an illustrative, self-designed example.
Break-Even Analysis for Product Businesses
For product-based businesses — manufacturers, e-commerce sellers, retailers — variable costs are usually a larger share of the price, since every unit carries real material, labor, and shipping costs. Break-even analysis here is especially useful when evaluating a new SKU: if the required break-even volume is unrealistic given market size, the product may not be viable at that price point.
Example: An e-commerce brand launches a $40 product with $10,000 in fixed launch costs (photography, ads setup, packaging design) and $18 variable cost per unit. Contribution margin is $22; break-even is $10,000 ÷ $22 ≈ 455 units. This is an illustrative, self-designed example.
Limitations of Break-Even Analysis
- Assumes selling price and variable cost per unit stay constant at every volume, ignoring bulk discounts or price elasticity.
- Assumes all units produced are sold — it doesn’t account for unsold inventory.
- Treats all costs as strictly fixed or variable, when many real-world costs are semi-variable.
- Doesn’t factor in taxes; break-even here is a pre-tax figure.
- Becomes more complex — and less precise — for businesses with multiple products at different margins.
- Is a static snapshot; it doesn’t account for costs or prices that will change over time.
Common Break-Even Analysis Mistakes
- Misclassifying a fixed cost as variable (or vice versa), which skews the entire calculation.
- Forgetting semi-variable costs like utilities or phone plans that have both a fixed base and a variable component.
- Ignoring payment processing fees, returns, or shipping as part of variable cost per unit.
- Assuming break-even volume is realistic without checking it against actual market demand.
- Running break-even analysis once and never updating it as costs or prices change.
- Confusing break-even revenue with break-even profit — break-even revenue still means zero profit, not positive profit.

Frequently Asked Questions
What is a break-even point in simple terms?
A break-even point is the amount of sales — in units or dollars — where your total revenue exactly equals your total costs. Below that point you’re losing money; above it, you’re profitable. It’s the line between loss and profit for any product, service, or business.
How do I calculate my break-even point?
Subtract your variable cost per unit from your selling price to get contribution margin, then divide your total fixed costs by that contribution margin. The result is your break-even point in units. Multiply that by your selling price to get break-even revenue in dollars.
What’s the difference between contribution margin and gross margin?
Contribution margin subtracts only variable costs from selling price and is used specifically for break-even and volume decisions. Gross margin subtracts cost of goods sold (which can include some fixed manufacturing overhead) from revenue and is used for overall profitability reporting. The two can differ depending on how costs are classified.
What happens if my contribution margin is negative?
If your variable cost per unit is equal to or greater than your selling price, contribution margin is zero or negative, and there is no sales volume that will let you break even — every unit sold increases your loss. You’d need to raise your price, cut variable costs, or both before break-even is mathematically possible.
Does break-even analysis include taxes?
No. The standard break-even formula is a pre-tax calculation. To estimate an after-tax break-even point, you can gross up your fixed costs by dividing them by (1 − tax rate), which accounts for the additional revenue needed to cover tax owed on profit above break-even.
Is break-even measured monthly, annually, or per unit?
It depends on how you input your fixed costs. If you enter monthly fixed costs, your result is a monthly break-even volume; annual fixed costs produce an annual break-even volume. The calculation itself doesn’t change — just make sure your fixed costs and your interpretation of the result use the same time period.
Can service businesses use a break-even calculator?
Yes. Service businesses simply define their “unit” as an hour, a session, a client, or a project instead of a physical product. Fixed costs (rent, salaries, software) and variable costs (materials, per-client supplies) work the same way, and the same formula applies.
What’s the difference between fixed and semi-variable costs?
Fixed costs don’t change with sales volume at all, like rent. Semi-variable costs have both a fixed base and a variable component, like a phone plan with a flat monthly fee plus per-minute charges. For accurate break-even analysis, semi-variable costs should be split into their fixed and variable portions before entering them into the calculator.
How do businesses with multiple products calculate break-even?
Multi-product businesses typically calculate a weighted-average contribution margin based on their sales mix, then apply the same fixed-costs-divided-by-contribution-margin formula. This calculator is built for a single product or service; businesses with several product lines at different margins should run the calculation separately for each, or use a blended average.
What is a good break-even point for a small business?
There’s no universal target — a “good” break-even point depends on your market size, sales cycle, and how quickly you can realistically reach that volume. A useful gut check is comparing your break-even volume to reasonable, evidence-based demand estimates for your market rather than to any fixed benchmark.
How often should I recalculate my break-even point?
Recalculate whenever your fixed costs, variable costs, or selling price change — a rent increase, a new hire, a supplier price change, or a pricing adjustment all shift your break-even point. Many businesses also review it quarterly as a routine check even if nothing obvious has changed.
Does a lower break-even point always mean a better business?
Generally a lower break-even point means less risk and faster profitability, but it isn’t the only measure of business health. A business can have a very low break-even point and still have thin overall profit margins, or a higher break-even point but much larger profit potential once past it. Break-even should be considered alongside total profit potential, not in isolation.
Key Takeaways
- Break-even is the sales volume where total revenue exactly equals total costs — zero profit, zero loss.
- Break-Even Units = Fixed Costs ÷ (Selling Price − Variable Cost per Unit).
- Contribution margin (selling price minus variable cost) determines how many units you need to sell to break even.
- A negative or zero contribution margin means break-even is mathematically impossible until price or costs change.
- Raising price lowers your break-even volume on paper, but can reduce actual demand — the two effects should be weighed together.
- Break-even analysis is a static, pre-tax estimate; treat it as a planning tool, not a guarantee.
- Both service and product businesses can use the same formula by defining their own “unit.”
