Gross profit vs net profit: which number tells you the business works

Gross profit is what's left after you pay for the work itself. Net profit is what's left after you pay for everything. Gross tells you if your pricing and delivery make money. Net tells you if the business does.

You need both, because each one points to a different problem. Most owners watch one and guess at the other.

The two formulas

Gross profit = revenue minus the cost of delivering what you sold. In a service business that's mostly the people doing the work (their wages and payroll taxes), plus anything the job itself uses up: materials, subcontractors, software you pay for per client.

Net profit = gross profit minus everything else. Rent, admin staff, marketing, insurance, software that runs the business, your own salary, interest and taxes.

Divide either one by revenue and you get the margin. Gross margin and net margin are the same numbers as percentages, which makes them easy to compare month to month.

A worked example

Say you run a service business doing $1.2 million a year. (Made-up numbers, used only to show the math.)

• Revenue: $1,200,000
• Cost of delivery: $540,000
• Gross profit: $660,000 (55% gross margin)
• Everything else: rent, admin, marketing, software, your salary: $564,000
• Net profit: $96,000 (8% net margin)

So the work makes money. 55 cents of every dollar is left after you deliver. Then the rest of the business eats 47 of those 55 cents.

That's the whole point of having two numbers. If gross margin were 30%, I'd look at pricing and delivery first: you're charging too little or the work takes too many hours. Gross is healthy here, so the problem lives below the gross profit line. Overhead grew faster than the business did.

The misread

The misread is "we need more revenue."

Run the same business up to $2 million. To get there, the owner discounts to win bigger accounts and hires delivery staff ahead of the work. Gross margin slips to 45%. Overhead keeps growing too, a second manager, more software, a bigger office.

• Revenue: $2,000,000
• Gross profit: $900,000 (45%)
• Everything else: $820,000
• Net profit: $80,000 (4%)

$800,000 more revenue. $16,000 less profit.

Not more money. More work for less.

That happens all the time, and the owner usually can't see it because the bank account is busier than ever. Revenue went up, so it felt like progress.

How to read the two together

What counts as healthy depends on your industry, and I'd rather you compare against your own last 12 months than an average from a study. The trend tells you more than the benchmark.

Run your own numbers

Once you know gross profit, the next question is where it goes. The free Capital Allocation Calculator splits gross profit into three buckets, running the business, making it stronger and paying you back, and shows each against a healthy range. It takes about two minutes.

Your move this week

Pull your last 12 months and write down two numbers for each month: gross margin and net margin. Not revenue. Just the two margins.

If gross is sliding, look at pricing and delivery hours. If gross holds and net is sliding, look at what you added to overhead and when you added it.

Revenue is the number everyone asks about. Gross and net are the ones that tell you the truth.

FAQ

What's the difference between gross profit and net profit? Gross profit is revenue minus the direct cost of delivering what you sold. Net profit is what's left after every other expense too, including overhead, interest and taxes.

What counts as cost of goods sold in a service business? Mostly the wages and payroll costs of the people who do the client work, plus materials, subcontractors and anything you pay for per client. Admin, marketing and rent sit below the gross profit line.

Is net profit before or after tax? Strictly, after. Many owners track profit before tax month to month because taxes are lumpy. Pick one and use it the same way every month.

Can a business have strong gross profit and still lose money? Yes. It's a common pattern: the work is priced fine, and overhead quietly eats the margin.

Which one should I watch? Both, every month. Gross tells you if the work makes money. Net tells you if the business does.
