blog-intro">You're busy. Jobs are going out. Invoices are getting paid. But at the end of the month, you're not sure if you actually made money — or just moved it around.

That's not a revenue problem. That's a numbers-clarity problem. And the first number every trades or service business owner needs to know is their break-even point.

What Is a Break-Even Point for a Small Business?

Your break-even point is the exact amount of revenue you need to bring in before you start making a profit. Below that number, you're losing money. Above it, you're building one.

It sounds simple. Most owners don't know theirs.

Here's what I tell every client when we start working together: if you don't know your break-even point, you're flying blind. You might be pricing jobs correctly and still losing money because your fixed costs are too high. Or you might be turning down work that would've pushed you into profit.

Knowing your break-even point for your small business changes how you make decisions — on pricing, on hiring, on overhead. Everything.

The Two Numbers You Need First

Before you can calculate your break-even point, you need two things nailed down.

1. Your total monthly fixed costs. These are the expenses that show up whether you do one job or twenty — insurance, vehicle payments, software subscriptions, rent, your own salary. If you haven't mapped these out yet, start with our post on what monthly fixed costs are and how to cut the right ones.

2. Your gross margin percentage. This is the percentage of each dollar of revenue left after you pay your direct job costs — materials, subcontractors, labour. If you're not clear on this, read our post on what gross margin is and why your trades business depends on it.

Get those two numbers. Everything else follows.

The Break-Even Formula (No Accounting Degree Required)

Here it is:

Break-Even Revenue = Total Fixed Costs ÷ Gross Margin %

That's it. Let's run through a real example.

Say you run a small electrical contracting business. Your monthly fixed costs — insurance, truck payment, accounting software, your draw — add up to $18,000. Your gross margin on jobs is typically 40%.

$18,000 ÷ 0.40 = $45,000

You need to invoice $45,000 every month just to break even. Every dollar above that is actual profit. Every dollar below it means you're covering overhead out of your own pocket.

Now you have a target. Not a vague sense that you "need more work." A number.

Why Most Owners Get This Wrong

The most common mistake I see is owners calculating break-even based on revenue alone — without accounting for gross margin.

They think: "I need $45K in jobs." But if their margin is only 25% instead of 40%, the real break-even is $72,000. That's a $27,000 gap they don't even know exists.

This is exactly why small businesses that look busy aren't actually profitable. The revenue looks fine on the surface. The margin math is broken underneath.

The fix isn't working harder. It's knowing your numbers — and pricing accordingly. If you're not sure your pricing is right, check out our guide on how to price your jobs properly as a trades contractor.

How to Use Your Break-Even Point Week to Week

Calculating it once isn't enough. You need to use it.

At TradeBrain, we recommend every owner track their invoiced revenue against their break-even target on a weekly basis. Not monthly. Weekly. By the time you catch a shortfall at month-end, it's too late to do anything about it.

Here's how to put it to work:

Know your weekly break-even number. If your monthly break-even is $45,000, your weekly target is roughly $11,250. That's your floor, not your goal.

Track invoiced revenue, not collected revenue. Cash flow and profitability are different problems. For the break-even calculation, use what you've invoiced. For the cash side of things, read our post on small business cash flow management.

Recalculate when anything changes. Hired someone? Got a new truck payment? Your fixed costs went up, which means your break-even went up. Recalculate your break-even any time your fixed costs change by more than $500/month.

What to Do If Your Break-Even Is Too High

If you run the numbers and your break-even feels impossible to hit consistently, you have two levers.

Lower your fixed costs. Go line by line through your overhead and cut what isn't earning its keep. Subscriptions you don't use. Equipment you're financing but barely touching. A lease that made sense two years ago but doesn't now.

Increase your gross margin. This usually means raising prices, tightening your job costing, or being more selective about which jobs you take. Low-margin work that keeps you busy is not the same as profitable work that builds the business. This connects directly to the operations improvements that actually move the needle without adding headcount.

Both levers matter. Most owners default to chasing more revenue when the smarter move is fixing the margin or trimming the overhead first.

Do This This Week

1. Pull up your last three months of expenses and add up every fixed cost. Use your bank statements, not memory.
2. Calculate your average gross margin percentage from your last 10 jobs. Revenue minus direct costs, divided by revenue.
3. Run the formula: Fixed Costs ÷ Gross Margin % = Break-Even Revenue.
4. Divide by 4.3 to get your weekly break-even target.
5. Write that number somewhere you'll see it every Monday morning.
6. If your break-even feels unreachable, identify one fixed cost to cut and one job type where you can improve margin.
