Labor Burden: What an Employee Really Costs You Per Hour

9 min read

Ask a contractor what an employee costs and you’ll usually hear their wage. “My lead carpenter is $32 an hour.” That number is what shows up on the paycheck, and it is not what the carpenter costs. By the time payroll taxes, workers’ comp, insurance, paid time off, and non-billable hours are counted, that $32-an-hour employee routinely costs $45 or more for every hour they actually produce work — and if your pricing is built on the wage instead of the loaded cost, the gap comes straight out of your profit on every single job.

That gap has a name: labor burden. This guide walks through what goes into it, how to calculate your own number with math you can check, and what it means for the rate you charge. When you’re ready to run your own figures, the free True Hourly Rate Calculator does the arithmetic for you.

What labor burden actually is

Labor burden is everything it costs to employ someone beyond their gross wages. Add the burden to the wage and you get the fully burdened labor cost — the real number a job estimate should be built on. It comes in two layers:

Direct burden — costs that scale with payroll: employer payroll taxes, workers’ compensation premiums, unemployment insurance, and benefits like health insurance contributions, retirement match, and paid time off.

Productivity burden — the hours you pay for that produce no billable work: drive time between jobs, shop time, training, rained-out days, and the paid holidays and vacation baked into the year. You pay for 2,080 hours; you bill far fewer. Whatever the employee costs has to be recovered over the hours that actually generate revenue.

The components you can look up today

Employer payroll taxes (the federal floor)

These are the non-negotiables, and they’re published by the IRS:

Social Security and Medicare (FICA). The employer pays 6.2% for Social Security and 1.45% for Medicare — 7.65% of gross wages, matching what the employee pays. For 2026, the Social Security portion applies to the first $184,500 of each employee’s wages; Medicare has no cap. (Source: IRS Topic No. 751, pulled September 5, 2026.)

Federal unemployment (FUTA). The FUTA rate is 6.0% on the first $7,000 of each employee’s annual wages, but employers who pay their state unemployment taxes on time generally receive a credit of up to 5.4%, bringing the effective federal rate to 0.6% — at most $42 per employee per year. (Source: IRS Topic No. 759, pulled September 5, 2026.)

State unemployment (SUTA). This one varies too much by state to quote a single number honestly. Each state sets its own taxable wage base and its own rate schedule, and your specific rate depends on your claims history (your “experience rating”). New employers get a state-assigned starting rate. Your rate is on the notice your state unemployment agency mails you each year; the U.S. Department of Labor’s state UI law comparison lists every state’s wage base and rate provisions.

Workers’ compensation

For the trades, workers’ comp is often the largest single burden item after taxes — and it’s the one where guessing is least defensible, because your actual rate is printed on your policy. Comp premiums are quoted per $100 of payroll and vary enormously by classification code: an office administrator and a roofer at the same company carry very different rates because the risk is different. Your classification codes and rates are on your policy’s declarations page; your insurance agent or state rating bureau can confirm which codes apply to each employee. Pull the real number from the policy — don’t use an industry average, because averages blend office clerks with steel erectors and are wrong for everyone.

Benefits and paid time off

Health insurance contributions, retirement match, uniforms, phone allowances, small tools, and training all belong in the burden. So does PTO, which is really a productivity cost: two weeks of vacation plus six holidays is 128 hours you pay for at full wage and bill at zero.

How to calculate your burdened rate

The formula is one line:

Fully burdened hourly cost = total annual cost of the employee ÷ annual productive (billable) hours

Here’s the whole method, using round numbers so the arithmetic is easy to follow. This is an illustrative example, not a benchmark — your taxes, comp rate, benefits, and productive hours will differ, and the point of the exercise is to replace every one of these numbers with your own.

Say a technician earns $30/hour — $62,400 a year at 2,080 hours.

Direct burden, using example rates: employer FICA at 7.65% adds $4,774. Effective FUTA adds $42. Suppose the state unemployment bill comes to $500 and the workers’ comp class rate for this employee works out to $5 per $100 of payroll — $3,120. Add a $6,000 employer share of health insurance and $1,500 in phone, small tools, and training. Total cost of employment: roughly $78,300 — already 25% above the wage.

Now the productivity side. Of 2,080 paid hours, subtract 80 hours of vacation, 48 of holidays, 40 of training, and 312 of drive and shop time (about 1.5 hours a day). That leaves 1,600 productive hours.

$78,300 ÷ 1,600 hours = about $49 per productive hour — for an employee whose “cost” you might have carried in your head as $30. That gap — $30 on the paycheck, roughly $49 out the door — is 63% in this example. It is arithmetic, not a benchmark: it falls straight out of the burden items and the productive-hour count above, and it moves the moment you swap in your own comp rate, benefits, or billable hours. We’re not claiming 63% is normal, because we have no sourced figure for what’s normal. What holds regardless of the inputs is the direction: a bid priced off the wage always understates the cost, which is why it looks profitable on paper and isn’t in the bank.

What this means for your billable rate

The burdened cost is a floor, not a rate. On top of it you still need to recover general overhead — rent, vehicles, office staff, software, marketing, your own salary — and then profit. That’s a second calculation: take the burdened cost of your crew, add overhead recovery, add the margin you’re targeting, and divide by billable hours. The free True Hourly Rate Calculator chains those steps together, and the markup vs. margin guide covers the pricing math that sits on top.

From burdened cost to the price you actually charge

The burdened number tells you what an hour costs. It does not tell you what to charge. Two steps sit on top, and the second is where most of the money quietly goes.

Step one: recover your overhead per billable hour

Rent, vehicles, office staff, software, marketing and your own salary don’t belong to any one job, so they have to be spread across the hours you can actually bill. The arithmetic mirrors the burden calculation — including the same trap.

Overhead per billable hour = annual overhead ÷ annual billable man-hours

A shop carrying $100,000 of annual overhead with four field employees has 8,160 paid man-hours (4 × 2,080). If 80% of those are billable, the denominator is 6,528 — and the overhead it must recover is $15.32 per billable hour. Divide by the paid 8,160 instead and you get $12.25, understating every hour by about a quarter. Same denominator mistake as the burden step, same direction: it always flatters you.

Step two: mark up correctly — markup is not margin

This is the most expensive piece of arithmetic in the trades, because the two words get used as if they mean the same thing and they don’t. Markup is what you add to your cost. Margin is what you keep out of the price. The conversion is fixed: margin = markup ÷ (1 + markup).

Conversion is arithmetic, not an industry benchmark: margin = markup ÷ (1 + markup). Checked September 8, 2026.

Read the first row twice, because it is the one that costs real money. A contractor who adds 30% believing he keeps 30% is actually keeping 23.1% — short by roughly seven points on every job, forever, and nothing in his bookkeeping will flag it. To hit a specific margin, solve backwards: markup = margin ÷ (1 − margin). A 30% margin needs 43% markup; 40% needs 67%; 50% means doubling the cost. The markup vs. margin guide works through the pricing side in full, and the Break-Even Calculator shows what volume that margin has to carry.

The mistakes that quietly eat the profit

Using 2,080 hours as the denominator. Nobody bills 2,080. Dividing by paid hours instead of productive hours understates the burdened rate by 20–30% before you’ve made any other mistake.

Pricing the crew at an average. A $22/hour helper and a $38/hour lead carry different burdens — comp codes, benefits, and productivity all differ. Burden each role separately.

Forgetting the burden moves. Comp rates change at renewal, state unemployment rates change with your claims history, and health premiums change annually. Re-run the number when the policies renew, not once a decade.

Treating overtime as pure profit hours. The wage premium is obvious, but taxes and comp scale with it too.

Run your own numbers

Every figure in the example above should be replaced with yours: the IRS rates from the sources linked, your state unemployment notice, your comp declarations page, your benefits invoices, and an honest count of productive hours. The True Hourly Rate Calculator turns them into your burdened cost and the rate you need to charge.

The bottom line

Labor burden isn’t a bookkeeping nicety — it’s the difference between what you think an hour of work costs and what it actually costs. The federal pieces are published and linked above; the state and insurance pieces are printed on documents you already have. An hour with those documents and a calculator will tell you more about your pricing than a month of gut feel, and if the burdened number surprises you, your bids have been quietly paying for the surprise all along.
