Revenue vs. Gross Profit vs. Net Profit

Walk onto any jobsite and ask the owner how business is going. Almost every time, you'll get a revenue number back. "We'll do about a million this year." Okay — but that number tells you how much money moved through his hands, not how much he got to keep. I've met plenty of guys doing a million who couldn't make payroll in February, and a few quietly doing $300k who were doing just fine.

There are three numbers you actually need to understand, and most owners blur them into one feeling of "we're busy, so we must be okay." They are revenue, gross profit, and net profit. Once you can tell them apart, you can finally answer the only question that matters: am I making money, or just staying busy? Let's take them one at a time, the way I wish somebody had explained it to me twenty years ago.

Revenue: the number that lies to you

Revenue is everything you billed and collected before you pay for a single thing. It's the top line. If you ran $100,000 through the business last month, your revenue was $100,000 — doesn't matter that $60,000 of it went straight back out the door for materials and labor.

Revenue feels good to say out loud, which is exactly why it's dangerous. A big revenue number with thin margins underneath it is how contractors talk themselves into thinking a money-losing business is a successful one. Revenue measures how much work you did. It says nothing about whether that work was worth doing.

Gross profit: what the job actually made

Gross profit is revenue minus the direct cost of doing that specific work — the materials, the labor that was on the job, your subs, the equipment you rented for it. These are the costs that only exist because you took the job. Take them out of what you billed, and what's left is gross profit.

This is the number that tells you whether your pricing works. If your gross profit is thin, one of two things is true: you're charging too little, or your job costs are running away from you. Gross profit is the first place to look when a business is "busy but broke," because it's measuring the gap between what you sell the work for and what the work costs you to deliver.

Net profit: the only number that pays you

Net profit is gross profit minus your overhead — and overhead is everything that costs money whether or not you land a single job. The truck payments. Insurance. The office. Software. Marketing. The phone. Your own salary. All of it has to come out of gross profit before anything is actually yours.

Net profit is what's left for you and for growing the business. It's the number that decides whether you can take a paycheck, weather a slow month, or hire help. You can have healthy gross profit on every job and still end the year with nothing if your overhead quietly ate all of it. That's why net is the only number that pays you — and the one most owners never actually look at.
