Ask a shop owner what an hour of their time costs and the answer usually comes back as a rate, which is a different number entirely and not the one the question was about. A rate is what gets charged. The cost is what the hour has to cover before anybody is actually paid: the truck, the insurance, the phone, the half day spent quoting work that went to someone else, and a wage for the person doing the quoting. Most people who price by the hour have never worked the second number out, and it runs higher than they expect.
Start With the Hours That Can Actually Be Sold
The arithmetic goes wrong at the very first step for almost everyone, because it starts from a full year of working hours. Fifty-two weeks at forty hours is a number that has never described anybody’s business. Take out vacation, holidays, and the days lost to weather or illness, then take out everything that is genuinely work but cannot be invoiced: driving between jobs, estimating, ordering material, chasing payment, fixing the trailer, and the Saturday morning that goes to paperwork because no other morning was free. What remains is the sellable hours, and for a one person shop it is frequently nearer half the year than all of it.
That figure is worth arriving at honestly rather than optimistically, because every later step divides by it, and an inflated denominator produces a comfortable-looking number that quietly loses money all year. The way to check it is to open last year’s invoices and add up the hours actually billed to customers. Not the hours worked, which nobody records accurately, but the hours a client paid for. That total describes the real capacity of the business as it currently runs, and it is the only defensible starting point for everything that follows.
Total What the Business Costs Simply to Exist
The next step is a list of everything the business spends in a year whether or not a single job gets sold. Insurance, both general liability and vehicle. The truck, whether that is a payment or the money quietly set aside to replace it. Fuel and maintenance. Tools and the steady replacement of them. Phone, software, accounting fees, license renewals, the storage unit, and the marketing that may or may not be working. Add the items that appear only once a year and are therefore forgotten, then add a line for the small unbudgeted costs that happen every month without ever being the same cost twice.
This total tends to startle people the first time it is written down in one place, largely because it has previously been experienced as a series of unrelated small annoyances rather than as a single annual figure. It is also the number that makes the difference between a wage and a business visible. An employee doing identical work carries none of these costs, which is why comparing a shop owner’s hourly rate against an employee’s hourly wage is a comparison between two different things wearing the same units.
Put Your Own Wage Into the Costs, Not Into What Is Left Over
The third step is the one most often skipped, and skipping it is what produces a business that runs for years without ever paying its owner properly. The owner’s wage belongs in the cost list, sitting alongside the insurance and the fuel, at whatever a competent person would have to be paid to do that job. Not what happens to be left at the end of the month. Not a figure chosen to make the final rate look competitive against the shop down the road. A real wage, decided in advance, that the business has to earn before it can be said to have broken even at all.
Anyone wanting an outside check on that figure can look at what the Bureau of Labor Statistics reports for the same trade in the same part of the country and treat it as a floor rather than a target, since an employee earning that wage is not also carrying a truck, a policy, and the risk of an unpaid invoice. The owner’s number should sit above it for exactly that reason. If the business cannot support it yet, that is useful information about the business rather than a reason to quietly lower the figure.
Divide, Then Sit With the Result for a Day
With three numbers in hand the arithmetic is trivial: annual costs plus the owner’s wage, divided by sellable hours. What comes out is the break-even hourly cost, which is not a price. It is the point at which the business has made nothing at all, and every hour sold below it is an hour the owner has paid a customer for the privilege of working. The first reaction is almost always that the result cannot possibly be right, followed by a search for an error, followed by the slower recognition that the error was in whatever number was being used before.
It is worth leaving alone for a day before doing anything with it. The temptation is to adjust an input until the answer looks more like the current rate, and that adjustment is the whole problem in miniature. Profit goes on top of the break-even figure as a deliberate margin, and it needs to be a real percentage rather than a rounding up to the nearest five dollars, because that margin is what funds the slow quarter, the replacement truck, and eventually somebody else’s wage.
Test It Against a Job That Is Already Finished
The last step is what turns a spreadsheet into something usable. Take a job that finished last year, one that felt fine at the time, and reprice it at the new number including every hour that actually went into it: the two return trips, the hour on the phone with the supplier, the afternoon spent waiting on an inspector who arrived late. Compare that against what was invoiced. A job that felt fine and comes out slightly underwater is the most instructive result available, because it shows exactly where the old rate had been hiding its losses.
The number will not survive unchanged for long, and it should not. Insurance renews higher. The truck gets older. A year with fewer sellable hours pushes it up on its own. Rechecking it once a year, at a fixed point on the calendar so that it does not depend on anyone remembering, keeps it honest without turning into a project. Ask a shop owner two years into that habit what an hour of their time costs and the answer comes back as a figure with a date attached, which is a much better answer than a rate and a considerably harder one to argue them out of.
