What Is the Break-Even Point?
The break-even point is the point at which total cost and total revenue are equal. That is how the US Small Business Administration (SBA) defines it.1 At that level of sales, the business has neither a loss nor a gain.
Below the break-even point, the business is losing money, because sales do not yet cover all of its costs. Above it, every extra sale adds to profit. The break-even point is therefore the first target any business needs to reach.
It can be measured in units sold, such as cups of coffee or software subscriptions, or in dollars of revenue. Both versions answer the same question: how much do we need to sell before we stop losing money?
Fixed Costs vs Variable Costs
To find your break-even point, you first need to split your costs into two groups.
| Type of cost | What it means | Examples |
|---|---|---|
| Fixed costs | Stay the same whatever you sell, at least in the short term | Rent, salaries, insurance, software subscriptions, loan repayments |
| Variable costs | Rise with every unit you make or sell | Ingredients, packaging, card processing fees, shipping, sales commissions |
The SBA describes fixed costs as expenses that stay the same regardless of how much you produce, and variable costs as per-unit costs that rise as you produce more.1 Some costs are mixed. An electricity bill, for example, has a fixed standing charge and a part that rises with use, so you split it between the two groups as best you can.
The Break-Even Formula
The SBA gives the formula for break-even in units as fixed costs divided by price minus variable costs.1
Break-even point (units) = Fixed costs ÷ (Price per unit − Variable cost per unit)
The part in brackets is called the contribution margin. It is the amount each sale contributes toward covering your fixed costs. Once enough sales have covered all fixed costs, each further sale’s contribution becomes profit.
To find the break-even point in dollars instead, divide your fixed costs by the contribution margin ratio, which is the contribution margin as a share of the price.
Break-even point (revenue) = Fixed costs ÷ (Contribution margin ÷ Price)
A Worked Example: A Small Coffee Shop
Here is an illustration with made-up figures for a small coffee shop.
- Fixed costs: $12,000 a month for rent, staff and insurance.
- Average price per drink: $8.
- Variable cost per drink: $3 for coffee, milk, cups and card fees.
Each drink contributes $8 − $3 = $5 toward fixed costs. Dividing $12,000 by $5 gives a break-even point of 2,400 drinks a month, or about 80 a day over 30 days. In revenue terms, that is 2,400 × $8 = $19,200 a month.
If the shop sells 3,000 drinks in a month, it makes 600 drinks’ worth of contribution above break-even, or 600 × $5 = $3,000 of profit. If it sells only 2,000, it loses 400 × $5 = $2,000.
How Changes Move the Break-Even Point
The break-even point responds to three levers: price, variable cost and fixed cost. Running the numbers for each shows which changes matter most for your business.
| Change (coffee shop illustration) | Contribution per drink | New break-even |
|---|---|---|
| Starting point | $5.00 | 2,400 drinks |
| Raise the price to $9 | $6.00 | 2,000 drinks |
| Variable cost rises to $3.50 | $4.50 | 2,667 drinks |
| Fixed costs rise to $15,000 | $5.00 | 3,000 drinks |
| Target $5,000 monthly profit | $5.00 | 3,400 drinks |
A $1 price rise cuts the break-even point by 400 drinks a month, as long as customers keep buying. A 50-cent rise in variable costs adds about 267 drinks. Small changes in price and cost per unit often matter more than people expect.
Planning for a Profit Target
The same formula tells you how much to sell to reach a profit goal. Add the profit you want to your fixed costs, then divide by the contribution margin.
Units needed = (Fixed costs + Target profit) ÷ Contribution margin
In the coffee shop illustration, making $5,000 a month takes ($12,000 + $5,000) ÷ $5 = 3,400 drinks. That is about 113 drinks a day. Seeing the target as a daily number makes it easier to judge whether it is realistic for the shop’s location and opening hours.

The margin of safety measures how far sales can fall before you hit the break-even point. It is the gap between your actual or expected sales and break-even sales, often shown as a percentage.
If the coffee shop sells 3,000 drinks a month and breaks even at 2,400, its margin of safety is 600 drinks, or 20% of sales. A larger margin of safety means the business can absorb a slow month, a price war or a rise in costs without slipping into a loss.
Why Lenders and Investors Ask for It
A break-even calculation shows that a business plan adds up. The SBA calls it an important calculation in a business plan, because investors want to know when they can expect a return, and notes that lenders and investors usually require it.1
The SBA also recommends that a business plan include financial projections, covering expected profit, assets and debts, and cash movements, to show the business can be a financial success.2 The break-even point links those projections to a concrete sales target.
For a new business, the break-even point is also a reality check. If the sales needed to break even are far beyond what the market can support, the plan needs a different price, a lower cost base or a different model. Our explainer on business models covers how companies turn value into profit.
Break-Even Point vs Profit Margin vs Cash Flow
These three ideas are related but answer different questions.
- Break-even point: how much must I sell to cover all my costs?
- Profit margin: how much of each dollar of revenue do I keep as profit?
- Cash flow: when does money actually arrive and leave?
A business can pass its break-even point on paper and still run short of cash, for example if customers pay late or stock must be bought months in advance. That is why cash flow planning sits alongside break-even analysis.
Break-Even for Different Kinds of Business
The method is the same everywhere, but the main costs differ.
- Retail and food: high variable costs for stock and ingredients, plus rent and staff.
- Software and subscriptions: low variable costs per customer, so most spending is fixed, such as salaries and servers. Break-even is about reaching enough paying subscribers.
- Services and freelancing: the main constraint is time. Divide your monthly fixed costs by your hourly rate, minus any direct costs per hour, to find the billable hours you need.
- Manufacturing: large upfront fixed costs for equipment, which makes volume especially important.
Businesses with high fixed costs and low variable costs have a high break-even point, but grow profitable quickly once past it. Businesses with low fixed costs break even sooner, but each extra sale adds less profit.
Break-Even With Several Products
Most businesses sell more than one thing, so they use an average contribution margin. The trick is to weight each product by how much of it you sell.
Suppose, in an illustration, the coffee shop’s sales are 70% drinks with a $5 contribution and 30% pastries with a $2 contribution. The weighted average contribution is (0.7 × $5) + (0.3 × $2) = $4.10 per item sold. With fixed costs of $12,000, the shop needs about 2,927 items a month to break even.
The sales mix matters. If customers start buying more low-margin items, the break-even point rises even if total sales stay the same. Tracking which products sell, not just how many, keeps the calculation honest.
How Long Until a New Business Breaks Even?
For a new business, the question is often not just how much to sell, but how many months it will take to get there. Sales usually start low and build up, so early months run at a loss.
Those early losses add up and must be funded, by savings, investors or a loan. Mapping expected sales month by month against the break-even line shows when you are likely to cross it and how much cash you need until then. That figure, sometimes called the cash runway, is a key number in any startup plan.
Many new businesses underestimate how long it takes to reach break-even. Building in a buffer of extra months, and extra cash, makes the plan far more resilient.
Using Break-Even to Set Prices
Break-even analysis turns a pricing decision into a clear trade-off. A higher price lowers the number of sales you need, but may also reduce how many customers buy.
Run the numbers at several prices. For each one, compare the break-even volume with a realistic estimate of demand from your market research. The best price is often the one that gives a comfortable margin of safety, rather than the one with the lowest break-even point on paper.
Remember that competitors’ prices set the range customers will accept. The SBA’s guidance on competitive analysis suggests studying what rivals offer and where they are strong.3
Limits of Break-Even Analysis
Break-even analysis is a planning estimate, not a precise forecast. The SBA notes that the break-even point is an estimate for planning and lender review rather than an exact accounting figure.1
- It assumes a single price. Real businesses sell many products at different prices and margins, so you may need an average.
- Costs are not perfectly fixed. Rent is fixed until you need a bigger space; staff costs rise when you hire.
- It ignores demand. The formula tells you what you need to sell, not whether customers will buy that much at that price.
- It ignores timing. It does not show when cash comes in or goes out.
Use it alongside market research and cash flow forecasts. The SBA’s guidance on market research and competitive analysis can help you test whether the required sales are realistic.3
Common Break-Even Mistakes
A few errors make break-even figures look better than reality.
- Leaving out the owner’s pay. If you need a salary to live on, include it in fixed costs.
- Forgetting small variable costs. Card fees, packaging and delivery charges add up across thousands of sales.
- Using list prices instead of real prices. Discounts and refunds lower the average price you actually receive.
- Treating the result as a forecast. Break-even tells you what you need to sell, not what you will sell.
Checking each assumption against real bills and real sales data keeps the number useful for decisions.
How to Calculate Your Own Break-Even Point
You can work it out in a spreadsheet in about half an hour.
- List every monthly cost. Use bank statements and bills so nothing is missed.
- Sort each cost into fixed or variable. Split mixed costs as best you can.
- Find your average price and variable cost per unit. If you sell many products, use a weighted average.
- Apply the formula. Divide fixed costs by the contribution margin.
- Test the levers. Change price, costs and volume to see what moves the result most.
Revisit the numbers whenever rent, wages, supplier prices or your own prices change. Inflation in particular can push variable costs up quietly, as our explainer on inflation describes.
Key Terms Explained
- Fixed costs: costs that stay the same regardless of sales volume in the short term.
- Variable costs: costs that rise with each unit produced or sold.
- Contribution margin: price minus variable cost per unit; what each sale adds toward fixed costs.
- Contribution margin ratio: contribution margin divided by price.
- Margin of safety: how far sales can fall before reaching the break-even point.
The Bottom Line
The break-even point tells you how much you must sell before your business starts making money. Split your costs into fixed and variable, divide fixed costs by the contribution margin, and then test how price and cost changes move the result. It is a simple calculation, but it shapes pricing, financing and every sales target that follows. For more, browse our business explainers.

Frequently Asked Questions
It is the level of sales at which your revenue exactly covers all your costs. You make no profit and no loss at that point.
Divide your fixed costs by the price per unit minus the variable cost per unit. The result is the number of units you need to sell to break even.
Raise prices, lower your variable cost per unit or cut fixed costs. Each change increases how much each sale contributes or reduces what it must cover.
It shows whether the business plan is realistic and when the business could start making a profit. The SBA notes that lenders and investors usually require it.
Break-even is the point where profit is zero. Every sale above that point adds profit equal to its contribution margin.
No. It looks at costs and revenue, not when money arrives or leaves. You need a separate cash flow forecast to see if you will have enough cash along the way.
