What Is a Burdened Labor Rate for Contractors?

Your payroll cost is taller than the wage once employer taxes, workers' compensation, and benefits are included. That full cost belongs in the labor line.

A burdened labor rate is the full cost of one paid labor hour, including wages and payroll burden. It is a cost, not what you charge the customer.

Quoting off the wage costs money. Owners keep doing it because the wage is visible right now: it is on the pay stub, in the payroll screen, and usually in your head. The rest shows up later in a quarterly payroll deposit, a benefits invoice, or a workers' comp audit after the payroll report. By then, the job that should have carried those costs may be closed.

The Burdened Labor Rate Is a Cost, Not a Price

You need three separate numbers to quote work cleanly. The burdened labor rate is what an employee's hour costs the company. Your charge-out hourly rate is what you sell that hour for after accounting for the business and the return you need. Overhead covers costs such as the truck, shop, tools, general liability, and software that keep running whether a particular employee is on a particular job.

Payroll tax and workers' comp follow payroll, so they belong with labor. The truck does not become cheaper when a crew member takes a day off, so it belongs in overhead. If you need to set that bucket, work from your own books and the method in what overhead percentage a contractor should use.

For the report-based method, use period totals and divide by the paid hours from that same period:

Burdened labor rate = (Total wages + Employer payroll taxes + Workers' comp + Benefits + Other payroll burden) ÷ Paid hours

That formula is for totals pulled from a payroll register, tax return, or insurance invoice covering one matched period. Mixing time periods produces a useless rate.

If every component has already been converted to a per-hour amount, add those hourly amounts and stop. Do not divide the sum by hours again. The example table below ($28.00 + $2.50 + $1.80 + $4.70 = $37.00) is that second method.

What Goes Into a Fully Loaded Hour

Start with the payroll register and use the wages you pay, separating straight-time and overtime where they differ. The register shows what you actually paid your own people during that period, while a borrowed percentage reflects someone else's shop, state, and benefit plan. Building from your payroll keeps the starting cost tied to the employee's paid hour.

Read the tax lines: employee withholding is money taken from the employee's check, not an extra company cost. The employer share of Social Security and Medicare, along with federal and state unemployment costs, adds to payroll. Including those amounts explains why the labor hour costs more than the wage shown to the employee.

Workers' compensation belongs in the hour because its premium is tied to payroll and the class of work that creates the exposure. Since a carrier may revise the premium when it audits payroll, use the audit to update the rate instead of treating an earlier estimate as final. Benefits and paid time belong for the same practical reason: the company pays for health coverage, retirement contributions, holidays, vacation, and sick time, as well as the Friday someone spends in the shop preparing for the next job. Those dollars still have to be recovered even when that paid time never appears on a customer ticket.

Other payroll-tied costs, such as processing, required paid leave, or employment-provided uniforms, should have a consistent home in your books. Keep each cost in one bucket so it does not disappear between labor and overhead or get counted twice.

That is the reasoning. Here is the order to work in with the reports open, holding one period steady the whole way down.

  1. Pick the period first, then pull the payroll register for it. A quarter is usually enough; a trailing twelve months smooths seasonal swings. Write those dates down so every figure matches. Take paid hours, gross wages, and the straight-time and overtime split.
  2. Total the employer tax lines for that same period. Labels vary, but look for employer Social Security or OASDI, employer Medicare, FUTA, and SUTA or state unemployment. Employee withholding stays out of this. It passes through your account rather than becoming a company cost.
  3. Bring workers' compensation onto the period. Prorate an annual premium. For payroll-based cost, use your invoice and class of work, not an online percentage.
  4. Total the employer-paid benefits for the same period and divide by paid hours: the employer health contribution, any retirement match actually paid, and paid holidays and time off when a productive-hours denominator is not already handling them. Split a mid-year change for historical work; use current cost for new quotes.
  5. Add the other payroll-tied costs you have assigned to labor, such as payroll processing, required paid leave, or uniforms provided as a condition of employment. Either bucket works. Both buckets at once does not. Pick one, write the choice down, and answer the same way next quarter.
  6. Divide the total loaded payroll cost by the paid hours from that period, and you have the loaded cost per paid hour. Check timesheets and use the productive-hour adjustment when non-ticket time takes a real share.

Choose one way to handle paid time off. Either include PTO dollars in the numerator and divide by paid hours, or leave PTO out of the numerator and let it reduce productive hours in the productive-hour calculation. Never do both, or the same days get counted twice.

Numbers show the shape. Say the quarter holds 500 paid hours, $14,000 in gross wages, $1,250 of employer taxes, $900 of prorated comp, and $2,350 of employer-paid benefits, with nothing in step five because processing sits in overhead. That is $18,500 of loaded payroll, and $18,500 ÷ 500 = $37.00 per paid hour, the same figure the example below builds. Made-up figures.

Where Each Number Lives When the Report Is Missing

Without a payroll service, use Form 941, the state unemployment return, check register, and bookkeeper detail. Labels vary, and this is not tax advice, so ask whoever prepares your filings. Divide annual comp across the same paid-hour base and update it after the audit. Split changed benefits for historical work and use current renewal cost for new quotes. Match all costs and hours to a partial-year window; never divide annual insurance by three months of hours.

Overtime Hours

Burden follows the wages, so an overtime hour carries more employer tax than a straight-time hour, and comp can move with it depending on your state and class. Multiplying the regular loaded rate by time and a half glosses over that. When overtime is material, load the overtime wage separately.

A Crew With Different Pay Rates

Per-person rates fit when a task belongs to a specific person, or when the gap between a lead's wage and a helper's is wide enough to change the answer. Use a blended rate when the same crew mix repeats and records support it. Weight by paid hours, not a simple average.

Subcontractors Are Not Payroll

A subcontractor's invoice is a job cost, closer to material than to a loaded hour, and no employee burden gets added to it because you pay no employer taxes, comp, or benefits on that person. Classification is a legal and tax issue, not a pricing choice; ask a professional.

If the Owner Is on the Payroll

An owner paid through payroll works like anyone else, so the employer payroll costs and employer-paid benefits on those wages belong in the rate. An owner draw is not payroll, though your time still needs a place in the price. Ask your tax professional about treatment.

Calculating a Burdened Labor Rate

These are made-up example figures chosen only to make the arithmetic easy to follow. They are not typical percentages, market wages, or advice about what your payroll should cost.

Example hour (made-up numbers, not a typical rate)
Hourly wage$28.00
Employer payroll taxes (example)$2.50
Workers' compensation (example)$1.80
Health insurance and other benefits, per hour (example)$4.70
Fully loaded cost per paid hour$37.00
$28.00 + $2.50 + $1.80 + $4.70 = $37.00

The wage is $28, but one paid hour costs the company $37. If a quote carries six labor hours at the wage, it includes $168. The same six hours at the loaded cost are $222. That $54 gap does not wait politely for the next job. It comes out of the money you thought was available for overhead and profit.

The $37 still is not a billing rate. It is the labor cost you need in the estimate before you add overhead and profit. Selling an hour for its loaded cost would cover that employee's hour and nothing else.

Sanity-Checking the Number

No universal ratio between a wage and its loaded cost fits every state, comp class, and benefit plan, so check the result against your own reports instead of a rule of thumb. Where employer costs exist, the loaded rate has to come out above the wage; if it equals the wage, an input is missing. Tie each add-on back to the invoice or report it came from. A rate near double the wage can be honest with rich benefits, heavy paid time off, or very low productive hours, but more often it means a unit or period mismatch or the same dollars counted twice. Rebuild the rate after a wage change, a comp audit, a benefits renewal, or a payroll tax change, and at least once a year besides.

Cost per Productive Hour: The Hours That Never Hit the Ticket

A paid hour and a job hour are not always the same hour. Someone spends Friday in the shop receiving material, cleaning the van, or getting Monday's work ready. There is also paid training, a slow morning waiting on a delivery, unbilled cleanup, holidays, and vacation. Payroll still runs, but none of those hours may appear on a customer ticket.

If you recover labor cost only through productive job hours, those hours have to carry the paid time that did not reach a job. Use your time records rather than guessing. The formula is:

Cost per productive hour = (Loaded cost per paid hour × Paid hours) ÷ Productive hours

Suppose you pay eight hours at the $37 loaded rate, but only 6.5 hours reach the ticket. The day's loaded payroll cost is $296, spread over 6.5 productive hours.

$37 × 8 ÷ 6.5 = $45.54

The cost on the job is $45.54 for each productive hour. Nothing new was added; the denominator changed to the hours that can actually recover the cost. If nearly every paid hour reaches a job, your paid-hour and productive-hour rates will be close. If shop, travel, waiting, and paid leave take a meaningful share of the week, the difference deserves a place in the quote.

Seasonal Work

Productive hours swing hard in seasonal work. Summer ticket hours do not resemble February shop days, so busy-month rates leave winter unfunded. Build separate seasonal rates, or use a trailing twelve-month rate weighted by paid hours.

Put the Loaded Rate on the Ticket

On an estimate, multiply planned labor hours by the number of workers and by the appropriate loaded rate. Use the productive-hour rate when those planned ticket hours must recover non-ticket time. Use the paid-hour rate only when your estimating method already handles nonproductive paid hours elsewhere.

Then add overhead separately. That keeps you from loading the shop and truck into payroll while still forgetting employer taxes. It also lets you compare estimated labor with the actual labor cost after the job, which is how you catch a production miss instead of blaming every short job on materials.

In the job profit calculator, enter the fully loaded cost in the hourly labor rate field, along with the crew size and hours. Add materials, drive, overhead, and your intended margin in their own places. The field needs the cost of labor, not the number printed next to hourly pay in your payroll system.

The expensive habit: typing the wage into a quote because it is the number you can see today. The quarterly deposit and comp adjustment arrive later, but they belong to the work you are pricing now.

Where This Usually Goes Wrong

  • Double-counting payroll processing or paid time off in burden and again in overhead. Pick one bucket per item, write it down, and read the two lists against each other once.
  • Taking a burden percentage from a forum post. It came from another state, class code, and benefit plan, so build yours from your own payroll report and comp invoice.
  • Letting a comp audit pass without touching the rate. Put the audited figure into the quotes you are writing now.
  • Dividing annual costs by a quarter of hours. Match the dates on both sides before you divide, and note the period on the sheet.
  • Treating paid hours as productive hours. Pull the timesheets, find what share reaches a ticket, and apply one method everywhere.

Frequently Asked Questions

What if I have no employees?

If you have no W-2 payroll, you may not need an employee payroll burden calculation. Your own time still has a value and cannot go into a quote at zero. Build what you charge for that time with the charge-out hourly rate method. If your company runs payroll for you, include the related employer costs just as you would for any other person on payroll.

The workers' comp audit changed my premium after the job closed. Do I go back and reprice old work?

A closed job usually stays closed. The audit tells you that the rate used on earlier quotes did not cover the final premium. Update the workers' comp amount in your burdened rate for new work, and account for any audit balance in your current books rather than pretending the old rate is still accurate.

The Bottom Line

Pull the employer costs from your payroll report and current bills, put them on the paid hour, and check how many paid hours actually reach tickets. Then carry that cost into each estimate. If you want to see the full job with labor, overhead, materials, and margin kept separate, run the numbers in the job profit calculator before you send the quote.
