Break Even Analysis Example: A Step-by-Step Walkthrough for a Small Service Business

Listen to this article

A break-even analysis answers one plain question: how much do you need to sell before the business stops losing money? For a small service business, such as a cleaning company, a lawn care crew, a bookkeeping practice, or a mobile detailing van, that number tells you whether your prices work, how many jobs you need each month, and how much room you have before a slow month turns into a cash problem.

This guide explains the formula, walks through a complete break-even analysis example for a small service business, and shows how to use the result to make better decisions about pricing, hiring, and growth. All numbers in the example are illustrative, so swap in your own.

What Is a Break-Even Point?

The U.S. Small Business Administration defines the break-even point as “the point at which total cost and total revenue are equal, meaning there is no loss or gain for your small business.” Below that point, you lose money. Above it, each additional sale contributes to profit.

To find it, you need to separate your costs into two groups:

• Fixed costs stay roughly the same each month no matter how many jobs you do. Think insurance, software subscriptions, a phone plan, a vehicle payment, rent for storage space, and your own base salary if you pay yourself one.
• Variable costs rise and fall with each job. For a service business, that usually means supplies, fuel, per-job labor, card processing fees, and disposal fees.

Some costs are a bit of both. The SBA calls these semi-variable costs and recommends splitting them into their fixed and variable parts where possible. A phone plan with a flat base fee plus overage charges is a common example.

If you need a refresher on which everyday expenses belong where, the guide to OPEX (operating expenses) covers the categories in more detail.

The Break-Even Formula

The SBA gives the standard formula:

Break-even point (units) = Fixed costs ÷ (Price per unit − Variable cost per unit)

The part in brackets, price minus variable cost, is called the contribution margin per unit. It’s the amount each sale contributes toward covering fixed costs. Once fixed costs are covered, the contribution margin becomes profit.

You can also calculate break-even in revenue:

Break-even point (sales dollars) = Fixed costs ÷ Contribution margin ratio

The contribution margin ratio is the contribution margin divided by the price. If each job earns $60 of contribution on a $150 price, the ratio is 0.40, or 40%.

For a service business, a “unit” is usually one job, one visit, one billable hour, or one monthly client. Pick the unit that matches how you actually sell.

Break Even Analysis Example: A Two-Person Cleaning Business

Here is a full worked example. The business, prices, and costs are illustrative and are not drawn from any real company or industry survey.

The business: A residential cleaning service run by an owner and one part-time helper. It sells a standard home clean for $150.

Step 1: List Monthly Fixed Costs

Fixed cost	Monthly amount
General liability insurance	$120
Scheduling and invoicing software	$60
Phone and internet	$90
Vehicle payment	$350
Marketing (local ads, website hosting)	$250
Owner’s base pay	$2,500
Accounting and bank fees	$80
Total fixed costs	$3,450

Including the owner’s pay matters. If you leave it out, you’ll “break even” while working for free.

Step 2: Work Out Variable Cost per Job

Variable cost per job	Amount
Cleaning supplies	$10
Fuel and vehicle wear	$12
Helper’s wages for the job	$60
Card processing fee (about 3% of $150)	$4.50
Replacement equipment set aside	$3.50
Total variable cost per job	$90

Step 3: Calculate the Contribution Margin

Price per job − variable cost per job = $150 − $90 = $60 contribution per job.

Contribution margin ratio = $60 ÷ $150 = 40%.

Step 4: Calculate the Break-Even Point

Break-even jobs = $3,450 ÷ $60 = 57.5 jobs per month.

You can’t do half a job, so round up: the business needs 58 cleans per month to cover all costs.

In revenue terms: $3,450 ÷ 0.40 = $8,625 per month.

Step 5: Turn It Into a Weekly Target

Monthly numbers can feel abstract. Divide by the number of working weeks. At about 4.3 weeks per month, 58 jobs is about 14 cleans per week, or roughly three per working day on a five-day week.

That’s a target you can check against your calendar every Monday.

Step 6: Add a Buffer

The SBA suggests it’s “a good idea to throw a little extra, say 10%,” into the analysis for expenses you can’t predict. Adding 10% to fixed costs gives $3,795, and $3,795 ÷ $60 = 63.25, so plan on 64 jobs a month as a safer break-even target.

What the Example Tells You

A break-even number is most useful when you ask “what if?” Here are four common scenarios using the same illustrative cleaning business.

Scenario	Change	New contribution per job	Break-even jobs per month
Base case	None	$60	58
Raise price to $165	+$15 price	$75	46
Helper gets a raise	+$10 labor per job	$50	69
Add a $400/month ad campaign	+$400 fixed costs	$60	65
Cut price to $135 to compete	−$15 price	$45	77

A few lessons stand out:

• Small price changes have a big effect. A $15 price increase cuts the break-even point by about a fifth. A $15 cut pushes it up by about a third. That’s why discounting to win work is so risky for a small service business.
• Variable costs matter as much as price. Every dollar added to the cost of a job comes straight out of the contribution margin.
• New fixed costs need new sales. The ad campaign only pays for itself if it brings in at least seven extra jobs a month ($400 ÷ $60 = 6.7).

If the price side of this feels uncertain, the guide on how much to charge for your services walks through setting prices that cover costs and profit.

Break-Even for Hourly and Retainer Services

Not every service business sells by the job. The same formula works with a different unit.

Hourly services (illustrative): A freelance bookkeeper charges $75 an hour. Variable costs per billable hour, such as software seats and processing fees, come to about $5. Fixed costs are $3,000 a month. Break-even = $3,000 ÷ $70 = about 43 billable hours per month. Since not every working hour is billable, the real question becomes whether the bookkeeper can sell 43 hours while still doing admin and sales.

Monthly retainers (illustrative): A social media manager charges clients $800 a month, with $100 in tools and contractor costs per client. Fixed costs are $4,200. Break-even = $4,200 ÷ $700 = 6 clients. Losing one client drops the business below break-even, which shows how concentrated the risk is.

Mixed services: If you sell several services at different prices, the SBA notes you can run the calculation for each service separately or use monthly totals. A simple method is to use your average contribution margin across a typical month’s mix of jobs.

Common Mistakes in Break-Even Analysis

• Leaving out your own pay. If the owner isn’t in fixed costs, the result describes a hobby, not a business.
• Forgetting annual and quarterly bills. Insurance renewals, licenses, and equipment servicing should be converted to a monthly amount. The SBA’s example is dividing a quarterly cost by four.
• Treating all labor as fixed. If you pay helpers by the job or by the hour, their wages are variable.
• Ignoring unbillable time. Travel, quoting, and admin don’t earn money but still use capacity.
• Using a best-case price. If you often discount, use your average actual price, not your list price.
• Confusing break-even with cash flow. You can be above break-even on paper and still run short of cash if clients pay late. The guide to small business cash flow problems covers that gap.

How to Use Break-Even in Day-to-Day Decisions

Once you know your number, it becomes a quick test for many decisions:

• Before hiring: Add the new cost and recalculate. How many extra jobs do you need to pay for the hire?
• Before buying equipment: A $6,000 machine financed at $250 a month needs about four or five extra jobs a month at $60 contribution.
• Before running a promotion: Calculate the break-even at the discounted price and ask whether the promotion will really bring in that many more jobs.
• When setting goals: Use break-even as the floor, then set a profit target above it. For example, a $1,500 monthly profit target needs another 25 jobs at $60 contribution ($1,500 ÷ $60).
• When reviewing each month: Compare actual jobs to the break-even target. If you’re consistently close to the line, look at price and variable costs first.

The SBA also offers a free break-even calculator on its startup costs page if you want to check your figures.

A Simple Break-Even Worksheet

Use this short checklist to build your own analysis in a spreadsheet or notebook:

1. Choose your unit: job, hour, visit, or client.
2. List every fixed cost and convert it to a monthly figure.
3. Add your own pay to fixed costs.
4. List every variable cost per unit.
5. Subtract variable cost from your average actual price to get the contribution margin.
6. Divide fixed costs by the contribution margin.
7. Round up, then add a buffer of around 10%.
8. Convert the result into a weekly target.
9. Run at least three “what if” scenarios: a price change, a cost increase, and a slow month.
10. Recalculate whenever prices, wages, or major costs change.
