What is the break-even point?
The break-even point is the exact sales volume, in units or in revenue, where your total revenue equals your total costs. Below it, you're losing money on every sale. Above it, every additional sale is profit.

The break-even point formula
There are two ways to arrive at the same number, and most articles on this only show you one.
That's the equation method, the direct route. The contribution margin method gets you the same answer, written differently:
Contribution margin is just price minus variable cost. Accountants tend to use this phrasing because it's a number they're already tracking elsewhere. To get break-even point in revenue instead of units, multiply the unit result by price.
Four worked examples across industries
A SaaS product
Monthly subscription, one tier.
Break-even volume
512
customers, or $25,088 in monthly revenue.
A fitness studio
Rent, equipment lease, staff.
Break-even volume
134
members.
A furniture maker
Workshop rent, equipment, salaried staff.
Break-even volume
53
tables a month.
A consultant
Office, insurance, software.
Break-even volume
32 hrs
billable hours a month, about eight a week.
Notice the pattern: the businesses with the highest fixed costs relative to their contribution margin (the studio, the furniture maker) need meaningfully more volume than the consultant, whose low fixed costs and wide margin per hour make the bar much easier to clear. Fixed cost structure, not price alone, is what shapes how hard a business has to work to become profitable.
How long it typically takes to break even
The break-even point itself is a sales volume, not a date, but most people asking the question actually want a timeframe, sometimes called the break-even period.
For a new business, 6 to 18 months from launch is a common range, though it swings hard by industry and funding source. A service business with low fixed costs (consulting, freelance work) can clear break-even in a few months once it has a handful of steady clients. Capital-intensive businesses (restaurants, manufacturing, anything with heavy upfront equipment or buildout costs) more often run 12 to 24 months, sometimes longer.
Subscription and SaaS businesses tend to sit at the slower end for a different reason: customer acquisition cost is paid upfront, but revenue arrives in thin monthly slices. The CAC payback period is often the better timeframe question for that specific case, it isolates how long one customer takes to become profitable, separate from the business's overall break-even point.
None of these ranges are a target to hit. They're a sanity check. A break-even projection of 3 months for a capital-heavy restaurant, or 30 months for a lean consulting practice, is usually a sign an input is off, not a sign of unusual performance.
Break-even point for service businesses
The formula doesn't change for services. Replace "units" with billable hours, sessions, or client engagements. What changes is a factor that's easy to miss: not every hour in a working day is billable.
A consultant working what looks like a full-time schedule still loses hours to business development, admin, invoicing, and training. If only 60% of available hours are actually billable, a break-even figure of 32 billable hours a month might require 53 total working hours to achieve, a gap that matters when planning realistic capacity, not just the math itself.
This is one of the more common places service-business break-even estimates go wrong: the formula is correct, but the assumption about how many billable hours are actually achievable in a month is too optimistic.
Break-even point vs. break-even analysis
These get used interchangeably, but they're not quite the same thing. Break-even analysis is the process: gathering your fixed costs, variable costs, and price, and working through the math. The break-even point is the answer that process produces: one specific number. You do an analysis; you arrive at a point.
Why the break-even point matters beyond the math
Pricing. If your break-even point requires selling more units than your market realistically supports, the price is wrong before you've sold a single unit.
Fundraising. Lenders and investors read a break-even point as a sign you understand your own economics, a business plan without one raises the obvious question of whether the numbers were ever run at all. A well-supported loan application typically shows the break-even calculation alongside the assumptions behind each input, not just the final number, since a lender wants to see the reasoning was sound, not just the conclusion. Most lenders also want a separate debt service coverage ratio showing this specific loan is affordable on top of that business model.
Deciding what to cut. When costs need to come down, the break-even point shows you exactly how much a specific fixed cost is adding to the number you need to hit every month, a $500 software subscription on a $71 contribution margin adds roughly seven members' worth of sales to the target, a concrete way to weigh whether the tool is worth keeping.
Once you know your break-even point, the next natural question is how far above it you actually are. That gap (current sales minus break-even sales) is called the margin of safety, and it's a fair measure of how much revenue could drop before a business starts losing money again. A business selling 200 units against a break-even of 134 has a margin of safety of 66 units, or about 33%: meaning sales could fall by a third before losses begin. For a direct comparison of when to check which number, see the break-even point vs. margin of safety guide.
How break-even connects to contribution margin and CVP analysis
Break-even point is really the entry point into a broader family of related calculations. Contribution margin is the number doing the actual work inside the break-even formula. Understanding it on its own lets you see how a price or cost change moves the break-even point before you run the full calculation.
Cost-volume-profit (CVP) analysis extends the same formula one step further: instead of solving for zero profit, it solves for a specific profit target, and adds margin of safety as a companion measure. Break-even is the special case of CVP where the target profit is exactly zero.
Common mistakes in break-even thinking
Reaching break-even means the losses have stopped, not that the business is doing well. It's a floor, not a goal.
The standard formula assumes a single product with a single contribution margin. A business selling several products at different margins needs a weighted-average contribution margin across the product mix. Treating every product as if it had the same margin overstates or understates the real number.
Accounting break-even vs. cash break-even vs. payback period
These three get mixed together constantly, and the difference matters more than the math itself in some cases.
Accounting break-even (the number this page has been calculating) is when revenue equals costs on paper, based on when a sale is recorded. It says nothing about when the cash actually lands in the bank.
Cash break-even is the same idea measured in cash timing instead. A business that invoices customers on 60-day terms can be past its accounting break-even point every month while still waiting on cash from sales made two months ago: the accounting number looks healthy while the bank balance tells a tighter story. This is exactly what a runway calculation is built to catch, since runway is driven by cash in and cash out, not by when a sale is recorded. The DSO calculator measures that specific gap directly. How many days, on average, revenue sits uncollected before it becomes usable cash.
Payback period is a different measure entirely, a one-time calculation of how long an initial investment (equipment, a franchise fee, a launch budget) takes to be recovered. A business can clear its break-even point every single month and still be years away from paying back the original investment that got it started.
A concrete case: a business breaks even on paper in month 4, selling enough each month to cover that month's costs. But it invoices on 45-day terms, so the cash from month 4's sales doesn't arrive until month 5-6. Meaning cash break-even lags accounting break-even by roughly six weeks. Meanwhile the $40,000 in equipment that started the business took 11 months of accumulated profit to pay back, well past either break-even date. All three numbers are correct at once; they're just answering different questions.
When success itself raises your break-even point
Most break-even discussion frames a rising break-even point as bad news, a cost going up somewhere. But demand outpacing capacity does the same thing, and it's driven by the business doing well, not poorly.
A bakery selling out every day is a good problem, until it means renting a second oven, hiring another baker, or moving to a bigger space to keep up. Every one of those is a new fixed cost, and every new fixed cost raises the break-even point right along with it. The bakery isn't failing; it's just re-entered the climb toward a higher bar, driven by the exact demand that looked like unambiguous good news.
The same logic applies to a service business adding a new hire to handle overflow work, or a SaaS product investing in infrastructure to support a growing user base. None of it means something went wrong, it means the break-even point isn't a number to calculate once and file away. It moves with growth as much as it moves with trouble, and it's worth recalculating any time capacity itself changes, not just when costs feel like they're under pressure.
A step-by-step worksheet
Follow these steps with your own numbers, in order, and you'll arrive at a break-even point you can actually trust.
Rent, salaries, insurance, software subscriptions, loan payments. Anything that shows up whether you sell one unit or a thousand. Add up a full year's worth, including annual renewals, and divide by twelve for an accurate monthly figure.
Only include costs that scale directly with each unit sold. Materials, packaging, per-transaction fees, sales commissions, direct labor tied to production. Leave out anything that stays constant regardless of volume.
Use the price customers actually pay on average, after typical discounts, not the list price.
Price minus variable cost per unit. This one number is doing the real work in the next step.
The result is your break-even point in units. Multiply by price for break-even in revenue.
If the number is higher than what your market or production capacity can realistically support, that's the signal to revisit price or cost before anything else.
Reading a break-even chart
A break-even chart plots two lines against unit volume on the horizontal axis and dollars on the vertical axis: total cost, starting above zero at your fixed-cost level and rising with each unit produced, and total revenue, starting at zero and rising more steeply with each unit sold.
The point where the two lines cross is the break-even point. To the left of it, the cost line sits above the revenue line. Every unit in that range represents a loss. To the right, revenue overtakes cost, and every additional unit adds profit. The vertical gap between the two lines at any given volume is the profit or loss at that specific level of sales, which is what makes the chart more useful than the number alone: it shows the whole shape of the business, not just the one point where it tips over. For a real, downloadable spreadsheet that builds this chart automatically from your own numbers, see the free break-even Excel template.
Expenses that stay the same regardless of how much you sell. Rent, salaries, insurance, software subscriptions.
Expenses that scale directly with each unit sold. Materials, packaging, per-transaction fees, direct labor tied to production.
Price minus variable cost per unit. What's left from each sale to put toward fixed costs and eventually profit.
Contribution margin expressed as a percentage of price, useful for comparing products at different price points.
The gap between actual or expected sales and the break-even point, a measure of how much revenue could drop before losses begin.
The same formula as break-even, with a specific profit goal added to fixed costs before dividing. Break-even is the special case where that target is zero.
Break-even point and startup runway
For a pre-revenue or early-stage business, break-even point connects directly to a second question: how long can the business operate before it gets there. If a startup has $120,000 in the bank, spends $15,000 a month, and needs eight months of ramping sales before crossing its break-even point, that's $120,000 of runway against roughly $120,000 of projected spend before revenue catches up, a plan with almost no margin for delay.
A break-even point that moves out by two months because of a new fixed cost is really a runway problem wearing a break-even label.
Recalculating break-even after any change to price, cost structure, or sales pace directly updates that runway picture, or run the numbers directly on the runway calculator.
Why break-even looks so different across business models
The four worked examples above weren't picked at random, they trace a real pattern in how fixed and variable costs trade off against each other across different kinds of businesses.
High fixed cost, wide margin. Software and subscription businesses spend heavily upfront on product and team, but each additional customer costs almost nothing to serve. Break-even requires real customer volume, but the margin on each customer, once acquired, is unusually forgiving.
High fixed cost, thin margin. Manufacturing and physical retail carry heavy equipment, lease, and staffing costs, and materials eat into every individual sale. These businesses need meaningful, consistent volume just to clear the floor, which is why inventory and production planning matter so much more here than in a software business.
Low fixed cost, wide margin. Consulting, freelance work, and other low-overhead service businesses can reach break-even with a small number of clients, because there's little standing between price and profit besides the practitioner's own time.
Knowing which pattern your business falls into says a lot about which lever (price, volume, or cost structure) deserves attention first.
Break-even point outside of standard for-profit businesses
The formula applies beyond a typical product or service business. A nonprofit running a fee-based program (a workshop series, a membership tier) can calculate break-even the same way, using program fees as price and direct program costs as variable cost, to see how many participants a program needs before it stops drawing on general funds.
An event organizer uses the same math for ticket sales against venue, staffing, and catering costs. A software team deciding whether to build a feature in-house can treat development cost as a fixed investment and estimate the break-even point in terms of usage, revenue impact, or retention improvement needed to justify the build.
The formula doesn't care what industry it's applied to, it only needs a genuine fixed cost, a genuine variable cost, and a genuine price or value per unit to work against.
Strengths and limitations of break-even analysis
Worth holding both sides in mind before treating the number as a complete answer.
Three inputs (fixed costs, price, variable cost) produce an answer in minutes, no financial model required.
Separating fixed from variable costs surfaces exactly what has to be covered before any profit exists, which is useful on its own.
Knowing you need to sell 512 units doesn't tell you whether 512 buyers actually exist at that price.
Real fixed costs step up at certain volumes (a second location, a new hire) rather than staying flat indefinitely. See the section above on success raising break-even.
The standard formula treats every unit as selling at the same price, it doesn't account for volume discounts, promotional pricing, or a price that changes partway through the period being analyzed.
A sale in month one counts exactly the same as a sale in month twelve, no discounting for the fact that cash sooner is worth more than cash later, which matters more the longer it actually takes to reach the break-even point.
Signs it's time to recalculate your break-even point
A break-even figure doesn't expire on a schedule, but certain events should trigger an immediate recalculation rather than waiting for the next quarterly check-in. A rent renewal, a new hire, or a software contract renewal all change fixed costs directly. A supplier renegotiation, a shipping rate change, or a shift in payment processing fees change variable costs. A price change, obviously, changes contribution margin outright. Any one of these on its own is reason enough to run the numbers again rather than assuming last quarter's break-even point still holds.
The businesses that get surprised by break-even shifts are rarely the ones that recalculate too often. They're the ones that calculated it once, filed it away, and kept operating against a number that quietly stopped being true months earlier.
Frequently asked questions
It says nothing about actual demand: a break-even volume can be mathematically correct and still unreachable if the market won't support it. It assumes costs stay linear and price stays constant, when real fixed costs step up in jumps and real prices vary with discounts or promotions. And it ignores the time value of money: a sale in month one and a sale in month twelve count identically, with no discounting for cash sooner being worth more than cash later.
Margin of safety = current sales − break-even sales, or as a percentage: (current sales − break-even sales) ÷ current sales. It measures how far above break-even a business actually is, the cushion available before sales dropping would tip the business back into a loss.
No. At the break-even point, profit is exactly zero. Profit only starts on the unit sold after it.
Yes. A rent increase, a new software subscription, even a supplier raising prices shifts fixed or variable costs, and moves the break-even point without the product itself changing at all.
There's no universal number, it depends entirely on realistic sales volume for that specific market. A break-even point of 50 units a month is fine for a boutique with steady local demand and unreasonable for one that sells five items a week.
Yes. Replace "units" with billable hours or client engagements, and the same formula holds: fixed costs divided by the margin each hour or engagement contributes after direct costs.
Service businesses with low fixed costs and few physical inputs (consulting, freelance work, digital products) tend to have the lowest break-even points relative to revenue, since there's little to no cost of goods sold per unit. Capital-intensive businesses like manufacturing or restaurants carry higher fixed costs and need more volume to clear the same bar.
Break-even point is a recurring, ongoing measure: the sales volume needed each period to cover that period's costs. Payback period is a one-time measure: how long it takes an initial investment (equipment, a franchise fee, a product launch budget) to be recovered. A business can be past its break-even point every month and still be years from paying back its original investment.
Yes, if depreciation is a real ongoing cost of running the business (equipment wearing out, vehicles losing value) it belongs in fixed costs the same way rent does. It's a non-cash cost, which matters for cash-flow planning specifically, but it still belongs in an accounting break-even calculation.
Generally yes, but not unconditionally. A break-even point can be artificially low because fixed costs are too thin to support real growth, for example, a business with almost no marketing budget breaks even easily but also has no engine for finding new customers. The number is a floor to clear, not the only thing worth optimizing for.
The break-even point itself (a unit or revenue count) can't be negative, it's a count of sales, and you can't sell a negative quantity. What can happen is a negative or undefined result if variable cost per unit exceeds price, which means every sale loses money and no volume of sales reaches break-even until the price or cost structure changes.
No, it's purely an internal calculation based on your own costs and price. It tells you what volume you need, not whether that volume is achievable given competition, market size, or demand. Pair the number with market research before treating it as a business plan on its own.
Show the calculation with its assumptions stated plainly (fixed costs, price, variable cost, and where each estimate came from) rather than just the final number. Lenders and investors are evaluating whether the reasoning holds up, not just checking that a number exists.
Treat the recurring subscription and the one-time fee as two separate contribution streams. Calculate the ongoing break-even using only the recurring subscription's contribution margin, since that's what needs to sustain the business month over month, the one-time fee helps with cash flow and customer acquisition cost recovery, but it doesn't recur, so it shouldn't be baked into the ongoing break-even math.
