Gross Margin vs Net Margin

Short Answer: Gross margin is the share of revenue left after the direct cost of doing the work. Net margin is the share left after every cost, overhead included. A good gross margin is one high enough to cover your overhead and pay you what your household needs at the volume you can realistically sell. Many labor-based service businesses land somewhere around 30% to 50%, but the test against your own costs matters more than any industry average.

Owners ask "what's a good margin?" as if there were one number. There are two margins, they answer different questions, and the right level for each depends on the shape of your business. The good news is that the test for "good enough" takes one line of arithmetic.

What Is Gross Margin?

Gross margin is revenue minus direct costs (the costs that exist only because a job was done: crew time, materials, fuel on the route), divided by revenue.

Gross margin = (revenue − direct costs) ÷ revenue

It measures your pricing against the cost of delivery. If a job sells for $100 and costs $60 to do, the gross margin is 40%. That 40 cents is what each dollar of sales contributes toward everything else.

What Is Net Margin?

Net margin is what's left after overhead too (insurance, software, advertising, loan interest, the accountant), divided by revenue. For a small owner-run business there's one wrinkle: the owner's pay. In a sole proprietorship the owner's draw isn't an expense, so the "net" on the books is really profit before the owner is paid. Keep that in mind before comparing yours to anyone else's.

A Worked Example: A Landscaping Company's Two Margins

Take a hypothetical landscaping company, Greenline Landscaping: one owner, a crew of four, about $520,000 a year in revenue across three kinds of work.

• Gross margin: $187,200 ÷ $520,000 = 36%
• Net margin before owner pay: $114,000 ÷ $520,000 = about 22%

The overall gross margin is an average, and the average hides the story. Split by service:

Residential mowing is 30% of the revenue and only 20% of the gross profit. Every dollar of it leaves 24 cents; every dollar of installs leaves 42. If Greenline moved $52,000 of work (10% of revenue) from residential mowing to commercial contracts, gross profit would rise by $8,320 without a single price change.

What Is a Good Gross Margin for a Small Business?

It depends heavily on what you sell. Businesses where labor is the main direct cost, like landscaping, cleaning or trades, commonly run gross margins somewhere between 30% and 50%. Businesses reselling products often run lower. Software and advice run much higher, because the direct cost of one more sale is small. An industry average only tells you whether you're unusual. Whether your margin is enough comes down to one test:

Gross margin needed = (overhead + what you need the business to earn) ÷ revenue

Greenline's owner wants $72,000 a year for the household and $20,000 kept in the business for equipment and a reserve, after tax. The owner is taxed on all of the profit, including the part the business keeps, so that takes about $120,700 of profit a year. So:

($73,200 + $120,700) ÷ $520,000 = 37.3%

Greenline runs about 36%, so it falls about 1.3 points short, or roughly $6,700 a year. Each point of slippage from here (crew raises that prices don't follow, a jump in fuel) widens the gap by another $5,200. That's why the service mix matters so much here: the $8,320 mix shift above would close the gap on its own.

What Is a Good Net Margin?

Net margin is harder to benchmark, because owners pay themselves in such different ways. Two businesses with identical operations can show 22% and 10% net margins depending on whether the owner's pay is on the P&L.

To compare fairly, subtract a market wage for the work you do. If Greenline's owner were paid a $60,000 salary for running the crew and the office, net margin would be $54,000 ÷ $520,000, or about 10%. That is the number to hold against businesses where the owner is an employee, or against what a buyer would see.

For your own planning, the more useful comparison is profit before owner pay against the $120,700 target. Greenline is about $6,700 short of it.

What to Look For

• Gross margin by what you sell. The blended number can hold steady while a low-margin line quietly grows and a high-margin one shrinks.
• Gross margin drift over a year. Each point of Greenline's gross margin is $5,200. A two-point decline usually means direct costs rose and prices didn't follow.
• Where costs are classified. If crew wages sit in overhead instead of direct costs, gross margin looks like 74% and means nothing. Check your books put labor in the right place before comparing to anyone.

What a Finance Consultant Would Do Next

A consultant looking at Greenline would start with the 16-point gap between residential mowing and commercial contracts. They'd ask whether mowing prices can rise, whether some mowing routes should be dropped in favor of contract work, and what each option does to the crew's calendar. Then they'd weigh the owner's 1.3-point shortfall against next year's crew raises before recommending anything.

That analysis is what Occam's Model runs on your own books. It ties your direct costs to each revenue stream so you can see what each one leaves, scores your margins against benchmarks, and lets you test a price change or a cost cut before you make it. When you need extra help, an expert can review it with you.

Common Questions

What's the difference between gross margin and markup?
Markup is profit as a share of cost; margin is profit as a share of price. A job that costs $60 and sells for $100 has a 67% markup and a 40% margin. Mixing them up is a common way to underprice.

Is a higher gross margin always better?
Mostly, but not at any cost. A price rise that lifts margin can lose enough customers to lower total gross profit. Judge a change by the dollars of gross profit it produces, not the percentage alone.

Should I include my own labor in direct costs?
If you work on jobs yourself, the honest answer is to count a market wage for those hours somewhere. Otherwise the margin looks healthy only because you aren't paying for part of the work.

How do I raise my gross margin?
Raise prices, lower direct costs per job, or sell more of the higher-margin work. The third is often the least painful for customers.
