Are My Margins Real, or Am I Working for Free?

A margin your unpaid hours are paying for is not a margin. It is a subsidy, and it has an expiry date the day you stop showing up.

The P&L says 14%. You haven't taken a real wage in three years, and you're the one who does the books on Sunday night at the kitchen table, because who else is going to do them.

You'd tell anyone who asked that the business is profitable. And it is, sort of. It's profitable because you're cheap.

The test that tells you the truth

Here's the whole method. Price every hour you personally work at what it would cost to hire that skill, subtract it, and read what's left. That residue is the profit the business itself makes, and it's the number a buyer will work out in diligence whether you ever did or not.

Roughly 86% of small business owners have either no professional valuation or only a rough estimate. So most owners meet this arithmetic for the first time sitting across from a buyer.

Why "subsidy" is the right word

Somebody is covering the gap between what you charge and what the work actually costs to produce. That somebody is you.

That isn't automatically wrong. If you're subsidizing a business for two years while you build a customer base, you're making an investment with a plan attached.

But a subsidy that's been running for six years without anyone naming it is a different animal. It hides the pricing problem, it keeps pushing the hire back, and it leaves you with a business nobody else could run at the current price.

The buyer version shows up at the worst possible moment. In diligence, the replacement cost of your labor comes off the earnings, and the number you've been quoting for years drops in a single afternoon. The formal version of that adjustment is owner compensation replacement cost, and it's worth reading before a buyer walks you through it.

One afternoon, one P&L

You need last year's P&L and an honest count of your own hours. That's it.

To make it concrete, take a 6-person commercial landscaping company doing about $980K. The owner draws $45,000 a year, runs a crew three days a week, does all the estimating, and keeps the books on those Sunday nights.

  1. List your roles. For the landscaper that's crew labor, estimator, bookkeeper, and owner-plus-salesperson.
  2. Count the hours in each, per week. Call it 22 crew, 9 estimating, 6 books, 15 owner work. So 52 hours.
  3. Price each one at local hiring cost, loaded. Use what you'd actually have to pay once payroll taxes and insurance go on top, which is usually more than what you'd like to pay.
  4. Subtract the total from reported profit. Leave your own draw out of it completely, since a draw is a decision about distributions and doesn't count as a cost here.

The landscaper's substitution total lands around $118,000 a year, against reported profit near $137,000. The residue is roughly $19,000.

Nineteen thousand dollars on $980K of revenue is a 2% margin, not 14%, on the same customers in the same year.

Nobody made an accounting mistake there. The gap is the difference between a business that produces profit and one that turns one person's time into profit at below-market rates.

If reading the statement itself is where you get stuck, start with how to read a P&L. It takes about an hour to learn properly.

Three subsidies that get lumped together

Pull them apart, because each one gets fixed a different way.

The subsidy What it covers Why it goes uncounted
Unpaid management time Estimating, scheduling, chasing collections The one owners half-know about and the easiest to price, since the hiring market for it is visible
Unpaid technician time Running a crew, turning wrenches, doing the work Owners undercount this because it feels like the job rather than a cost
Deferred maintenance and equipment The truck at 240,000 miles, the mower you rebuilt twice, the software you never upgraded Nothing appears on the P&L, so it reads as discipline

The third one is what reprices a business at the worst time. A buyer walks the yard, prices out the replacement schedule, and takes it off the offer in one line.

The landscaper's yard has two trucks past their useful life and a mower that's been rebuilt twice. That's roughly $70,000 of capital being put off, and it never shows up as a cost in any of the three years the margin looks good.

Time away tends to expose all three at once. If two weeks off suddenly produces costs, those costs were there the whole time and you were covering them with your own hours.

So the number is bad. Now what?

The gut reaction is to cut costs. That's usually wrong, because the costs you'd cut are the ones you've already been dodging by working for free.

What you're facing is a pricing decision. If the test says the work costs more than you charge, either the price goes up or the work changes, and no amount of extra effort from you fixes that for good.

Run it on one job type first. Say the landscaper finds his residential maintenance routes fail badly while the commercial contracts pass with room to spare. That's one specific line of work to reprice or drop, and it took an afternoon to find.

Some businesses fail this test permanently at their current size, and you want to know that early rather than late. A business that can't pay a market wage for the owner's own roles won't sell at a price that reflects the effort.

If the result changes how you think about selling, it goes to the top of the defect list. Fix the business first or list it now is a much easier call to make with a real margin than with a flattering one.

And don't treat it as a one-time exercise. Watching the same few numbers every week is what catches the margin drifting back, which is the point of the first hour of your week. Run the subsitution test again every time you reprice a job type or hire into one of your own roles.


Pull last year's P&L this week, write down your roles, and price each one at what hiring it would really cost. The residue is your actual margin.

If you'd rather see the buyer's version of that adjustment first, Keystone's diagnostic does that, but it's closed right now while we finish the build. The waitlist is open, and you can add your name at https://app.trykeystone.io.

When it opens, it's 18 questions and about four minutes. You get three scores and your value range with the most likely figure locked, calibrated against 10 years of BizBuySell Insight Reports and 1.6M+ SBA 7(a) loan records.

One substitution test tells you where you are today. Tracking the residue month over month, as you reprice work or hire into a role, tells you whether the fix held, and the paid tier keeps that record.

Current tiers and what each one includes are on the pricing page.

FAQ

How do I know if my business is actually profitable?

Price every hour you personally work at what it would cost to hire that skill, subtract the total from reported profit, and read what is left. Leave your own draw out of it, because a draw is a distribution decision rather than a cost of producing the work.

How much should a small business owner pay themselves?

The useful question is not what you draw but what your roles would cost to replace at local loaded rates. If the business cannot cover that replacement cost and still show profit, the margin is being subsidized by your hours rather than produced by the business.

What is the cost nobody counts?

Deferred maintenance and equipment. A truck past its useful life or software never upgraded shows up nowhere on the P&L, so it reads as thrift, and a buyer prices the whole replacement schedule off the offer in one line.

What should I do if my margin fails the test?

Treat it as a pricing decision rather than a cost-cutting one, and run the test on one job type at a time. Owners frequently find one line of work fails badly while another passes comfortably, which is a specific thing to reprice or exit.
