Why charging by the hour is costing you money

In this article

This is the most expensive habit in the trades, and it survives because it feels fair. You worked five hours, you charged for five hours. Nobody can argue with it.

The trouble is what it does to you over time.

The paradox, in one job

Take a job you quote at $95 an hour and it takes five hours. You invoice $475.

Now do the thing every good operator does. You buy the right tool, or you have done forty of these and you have the sequence down, or you send the tech who is genuinely quicker. Same job, same finish, three and a half hours.

You invoice $332.50. You just did the same work better and earned $142.50 less for it. Your reward for improving was a 30% pay cut.

Now price the job instead. The job is $475 because that is what the job is worth. It takes you three and a half hours, so your effective rate went from $95 to $136 an hour — and the customer paid exactly the same money and knew the number before you started.

Nothing changed except what you sold. That is the whole argument.

Your hourly rate was never your hourly rate

The second problem is quieter and it is worse. When you say “I charge $95 an hour”, you are describing billable hours. You are paying for all of them.

Field service work commonly bills somewhere between 30% and 70% of a paid day, depending on the trade and how far apart the jobs are. Drive time, quoting, parts runs, the phone, the paperwork — all real, all unpaid, all yours. Independent operators typically land near the top of that band; a van‑based team with a spread‑out round lands near the bottom.

Here is what that does to a wage. Work it through with your own numbers:

Step	Working	Result
Tech pay	$30 an hour	$30.00
Payroll burden	Taxes, workers’ comp, liability — commonly 25–35%. Use 30%.	$39.00
Cost of a paid day	8 hours × $39	$312.00
Billable hours in that day	60% of 8 hours	4.8 hours
Labour cost per billable hour	$312 ÷ 4.8	$65.00
Overhead per billable hour	$8,000 a month ÷ (2 techs × 4.8 hrs × 21 days)	$39.68
Total cost per billable hour	$65.00 + $39.68	$104.68
Price to clear 15% net	$104.68 ÷ 0.85	$123.15

A tech on $30 an hour costs about $125 an hour of billable time to put in front of a customer at a modest profit. If you are charging $95 because that felt like a lot of money, you are working for the privilege.

The number that does the damage is the billable share. Drop it from 60% to 45% — one bad round, one wrong postcode — and the labour cost per billable hour goes from $65 to $86.67 without anybody working differently. This is the same arithmetic behind how to price a plumbing job and building a route that pays, and it is why density keeps coming up in these guides.

What the customer hears

There is a sales cost too, and it is easy to miss because you never see the jobs you did not get.

When you say “$95 an hour plus parts, probably two or three hours”, the customer does not hear a rate. They hear somewhere between $200 and $600, and I will not know until it is over. That is an open cheque, handed to a stranger, in their own house.

Uncertainty is expensive at the moment. Roughly three in five homeowners have delayed a repair because of cost, and about a quarter of those delayed it for six months or more. A price they cannot pin down is one of the easiest reasons to put the decision off — and a delayed decision is a lost job that never appears in your figures as a loss.

A flat price does something an hourly rate structurally cannot: it ends the conversation. “It is $420, and I can do it Thursday.” Yes or no.

When hourly is genuinely the right answer

Plenty of guides on this subject pretend hourly is always wrong. It is not, and pricing a job flat when you cannot see the job is how operators end up in the situation described in what to do when you have underquoted.

Hourly, or time and materials, is the honest choice when:

• Nobody can see the scope yet. Behind a wall, under a floor, inside a system that has been modified by four previous owners.
• The customer keeps changing their mind, and you would rather charge for that than fight about it.
• It is diagnostic work. You are selling the finding‑out, not the fixing.
• The job is genuinely one of a kind and you have no comparable to price from.

The mistake is not using hourly. The mistake is using it as the default for work you have done two hundred times and could price in your sleep.

How to move across without rebuilding everything

You do not need a full price book on day one. You need your top jobs priced, and the rest can stay hourly while you learn.

• List the jobs you actually do. Most operators find that eight to fifteen job types cover the large majority of their work.
• Go back through last year’s invoices and find out how long each really took. Not how long you think. The gap between the two is the article.
• Price from the cost of a billable hour, using the table above with your own pay, burden, overhead and billable share.
• Use the average, not the best case. You will price some jobs badly. Flat rate wins across a year, not on every single job, and the operators who abandon it usually quit after one bad one.
• Put the price on the door, not on the clock. Quote the job, in writing, before you start.
• Keep a genuine hourly rate for the unknowns and say plainly when you are using it and why.
• Review it every quarter for the first year. Your first price book is a draft.

Building a flat-rate price book works this through end to end. It is written for plumbing, but the method is the same in every trade in this catalogue.

What to stop doing

• Quoting a rate when they asked for a price. They are not the same answer and only one of them closes.
• Rounding your hours down because it took longer than you said. That is a discount you gave yourself for being honest, and it comes straight out of profit.
• Charging the same rate you charged three years ago because nobody complained. See how to raise your prices.
• Assuming a full day is billable. It is not, it never was, and that assumption is the single most common reason a busy operator makes no money.

Sources

Every figure above comes from one of these, checked in August 2026. The cost‑per‑billable‑hour table is worked from first principles so you can check each line against your own numbers.

• BLS Employee Benefits and Employer Costs for Employee Compensation — the basis for the payroll burden band. Burden varies widely by state and by trade; workers’ comp is the swing factor.
• Reporting on homeowners delaying repairs — the share of homeowners who have put off a repair on cost, and for how long.
• The 30–70% billable‑share band is drawn from field service trade reporting across several independent sources, which is also why it is published as a band rather than a figure. Measure your own for a fortnight; it is the most valuable number in this article and nobody else can tell you what it is.
