Break-Even Analysis for Small Businesses
Every small business has a line where it stops losing money and starts making it. Break-even analysis shows you exactly where that line sits, in units or in sales, so you can set prices, plan a hire or test a new product with real numbers instead of hope. This guide walks you through the formula, a step-by-step method and a template you can copy today.
Key takeaways
- Your break-even point is the level of sales where total revenue equals total costs, so you make neither a profit nor a loss.
- Break-even point in units = fixed costs divided by (price minus variable cost per unit).
- The gap between price and variable cost, called the contribution margin, is the number that does the heavy lifting.
- Use break-even analysis to test decisions before you make them: a price change, a new hire, a second location or a new product.
- Rerun the numbers whenever your costs or prices change, and at least once a year during planning.
Mid-December is a natural moment to ask a simple question: how much do I actually need to sell next year just to cover my costs? Maybe rent is going up in January, maybe you are thinking about your first part-time employee, or maybe you simply want to know whether this year's busy holiday season was profitable or just busy. Break-even analysis answers all of these with one short formula.
You do not need a finance degree or special software. If you know roughly what you pay each month and what each sale costs you, you can find your break-even point in an afternoon. A quick note before we start: this article is general information about business planning, not financial, tax or accounting advice. For decisions with real money at stake, talk to an accountant or a qualified adviser who knows your situation.
What break-even analysis tells you
Break-even analysis tells you the minimum amount of sales you need to cover every cost of running your business. Below that point you are losing money. Above it, each extra sale adds to your profit. It is a simple idea, but it changes how you look at your business, because it turns a vague goal like "sell more" into a specific target like "sell 420 candles a month."
It also shows which levers matter most. There are only three ways to lower your break-even point: cut fixed costs, cut variable costs per unit, or raise your price.
Fixed costs vs variable costs
The whole analysis depends on sorting your costs into two buckets. Get this part right and the rest is arithmetic.
- Fixed costs stay roughly the same no matter how much you sell in a month. Think rent, insurance, salaries for permanent staff, software subscriptions, loan repayments, your website and your accountant's fees.
- Variable costs rise and fall with each sale. Think raw materials, packaging, shipping, card processing charges, sales commissions and the hourly pay of freelancers you only book when you have orders.
Some costs are a mix. Your electricity bill might have a fixed standing charge plus a usage part that rises when your kiln or oven runs more. For a first pass, put each mixed cost in whichever bucket it mostly belongs to. You can refine it later.
Pro tip
Pull the last three to six months of bank and card statements and tag every outgoing payment as F (fixed) or V (variable). Averaging several months smooths out one-off spikes, such as an annual insurance payment that landed in a single month.
The break-even formula, explained simply
Here is the core formula you will use:
Break-even point (units) = fixed costs / (price per unit minus variable cost per unit)
The bottom half of that formula, price minus variable cost, has its own name: the contribution margin. It is the amount each sale contributes toward paying your fixed costs. Once enough sales have chipped in to cover the fixed costs completely, every further contribution is profit.
Break-even in units
If you sell physical products or clearly defined services, units are the most useful way to think. Divide your monthly fixed costs by your contribution margin per unit, and you get the number of units you must sell each month to break even. Always round up, because you cannot sell half a candle.
Break-even in sales revenue
If you sell many different items at different prices, a revenue target can be easier to work with. Divide your contribution margin by your price to get a contribution margin ratio, then divide fixed costs by that ratio. The answer is the sales revenue you need each month to break even. This version is handy for shops, cafes and anyone with a mixed menu.
Example
Imagine Maya, who runs a small candle studio. These numbers are made up for illustration. Her fixed costs are $3,600 a month for studio rent, insurance, software and a part-time assistant. Each candle sells for $30, and wax, wick, jar, label, packaging and payment charges come to $12 per candle. Her contribution margin is $30 minus $12, or $18. Her break-even point is $3,600 / $18 = 200 candles a month. In revenue terms, her contribution margin ratio is $18 / $30 = 0.6, so she needs $3,600 / 0.6 = $6,000 in sales each month. Candle number 201 is the first one that earns her a profit.
How to run a break-even analysis step by step
Now let's turn the formula into a routine you can repeat every time something changes. Set aside 30 to 60 minutes and work through these steps.
- Pick a time period. Monthly works for most small businesses because rent and payroll are monthly. Use the same period for every number.
- List your fixed costs. Add up everything you pay regardless of sales. Include your own pay if you want the business to support you, otherwise you are only breaking even on paper.
- Work out variable cost per unit. Add every cost that comes with one sale: materials, packaging, shipping, payment processing, commission. Be honest and thorough here.
- Confirm your average selling price. Use what customers actually pay after discounts, not your list price.
- Calculate the contribution margin. Price minus variable cost per unit.
- Divide. Fixed costs divided by contribution margin gives your break-even point in units. Round up.
- Sanity-check the result. Compare it with what you actually sell. Is the target comfortably below your typical month, or uncomfortably close to your best month ever?
- Run a few "what if" versions. Change one number at a time to see how sensitive your break-even point is to price, costs or a new expense.
Common mistake
Leaving your own salary out of fixed costs. Many owners proudly announce they break even at 150 sales a month, then wonder why they never have money to pay themselves. If the business is meant to support you, your pay belongs in the fixed cost list from day one.
A break-even analysis template you can copy
Copy these columns into a spreadsheet and add one row for each product, service or scenario you want to test. All amounts below are made-up examples for illustration only.
| Scenario | Monthly fixed costs (example) | Price per unit (example) | Variable cost per unit (example) | Contribution margin | Break-even units | Break-even revenue |
|---|---|---|---|---|---|---|
| Current setup | $3,600 | $30 | $12 | $18 | 200 | $6,000 |
| Price rises to $33 | $3,600 | $33 | $12 | $21 | 172 | $5,676 |
| Add a $900 a month hire | $4,500 | $30 | $12 | $18 | 250 | $7,500 |
In a spreadsheet, the contribution margin column is simply price minus variable cost. Break-even units is fixed costs divided by contribution margin, rounded up with a ROUNDUP formula. Break-even revenue is break-even units multiplied by price. Once the formulas are in place, you can change any input and see the effect instantly.
Add a target profit row
Breaking even is a floor, not a goal. To find the sales you need to reach a profit target, add the target to your fixed costs before dividing. If Maya wants $1,800 of monthly profit on top of her costs, she needs ($3,600 + $1,800) / $18 = 300 candles a month. That one extra row turns the template into a planning tool for next year.
Using break-even analysis to make better decisions
The real value of break-even analysis is not the single number. It is the way you can test a decision on paper before you commit to it.
Testing a price change
Look at the template above. A small price increase shrank Maya's break-even point by 28 candles a month, because the extra money goes straight into the contribution margin. Price is often your most powerful lever. Before raising it, consider whether you might lose some sales, and run a version with fewer expected sales to see whether the change still works.
Planning a hire or a bigger space
New fixed costs raise your break-even point. In the example, a part-time hire pushed the target from 200 to 250 candles. The question to ask is: will this hire help me sell at least 50 more candles a month, or free me up to do work that brings in that much? If the answer is a confident yes, the hire pays for itself. If you are unsure, consider starting smaller.
Launching a new product or service
Run a separate break-even calculation for anything new that comes with its own costs, such as equipment, a marketing campaign or extra stock. Divide the extra fixed costs by the new product's contribution margin to see how many you need to sell to recover the investment. If that number looks unrealistic, adjust the plan before you spend the money.
Setting a safety margin
Compare your expected sales with your break-even point. The gap between them is your margin of safety. A business that expects 320 sales against a break-even of 200 has plenty of room for a slow month. A business expecting 210 has almost none, and should look at costs or prices before January's quieter weeks arrive.
Pro tip for seasonal businesses
If December is your peak and February is your slump, calculate break-even for the year as well as for each month. Then you can see whether strong holiday sales will carry the quiet months, and plan cash reserves for the gap.
Break-even for service businesses and freelancers
If you sell your time rather than products, the formula still works. Your "unit" becomes a billable hour, a session or a project.
- Fixed costs are your monthly business overheads plus the pay you want to take home.
- Variable costs per unit might include subcontractor hours, travel to a client, materials or platform fees tied to each job.
- Price per unit is your average hourly rate or project fee after discounts.
Divide fixed costs by the contribution per hour to find how many billable hours you need each month. Then compare that with your realistic capacity. Remember that not every working hour is billable: admin, sales calls, invoicing and learning all take time. If your break-even hours are close to your total available hours, your rate is probably too low or your overheads too high.
Your break-even action plan
- Choose a period, usually one month
- List every fixed cost, including your own pay
- Add up the variable costs that come with one sale
- Confirm your average selling price after discounts
- Calculate contribution margin and break-even units
- Copy the template and add "what if" rows for price, hires and new products
- Add a target profit row for next year's plan
- Set a reminder to rerun the numbers whenever costs or prices change
Frequently asked questions
How often should I recalculate my break-even point?
At least once a year during planning, and any time a major number changes: a rent increase, a new supplier price, a price change or a new hire. Many owners make it part of a quarterly review so it never drifts far from reality.
What if I sell lots of different products?
Use the revenue version of the formula with an average contribution margin ratio across your sales mix. If one or two products make up most of your sales, you can also calculate break-even for each of them separately to see which ones carry the business.
Does breaking even mean I have enough cash?
Not necessarily. Break-even analysis looks at costs and revenue, not timing. If customers pay late or you buy stock months in advance, you can be above break-even and still short of cash. Keep an eye on cash flow alongside this analysis.
Is a lower break-even point always better?
Generally, yes, because it gives you more room for slow months. But do not cut costs that drive sales, such as marketing that works or staff who serve customers well. The goal is a break-even point you can beat comfortably, not the lowest possible number.

The bottom line
Break-even analysis gives you one clear number: the sales you need to cover your costs. Sort your costs into fixed and variable, find your contribution margin, divide, and you have a target that turns guesswork into a plan. Add "what if" rows and a profit target, and the same simple sheet helps you decide on prices, hires and new products.
Before the year ends, block out an hour, fill in the template with your real numbers and see where your line sits for next year. Knowing it will make every January decision a little calmer.
