If you bid labor at the number on your crew's pay stubs, you are losing money on every hour your people work. The wage on the paycheck is not your labor cost. The real cost includes payroll taxes, workers comp, unemployment insurance, health coverage, paid time off, and the hours that never show up on an invoice. Together, those extras typically add 25 to 45 percent on top of base wages. The number that includes all of them is called the burdened labor rate, and it is the single most important figure in your estimate.
Contractors who guess at labor cost or use the bare wage rate win bids they cannot afford to build. This guide walks through the exact components of a burdened rate, a step-by-step calculation you can run on your own payroll numbers, burdened rates by trade, and the mistakes that silently erase margin. If you want estimates where labor never leaks money, start here. Our team runs fully burdened labor in every construction estimating service we deliver, because an estimate built on wage rates is a promise built on sand.
What a Burdened Labor Rate Actually Includes
A burdened rate is your total annual cost for one employee divided by the hours that employee actually works productively. It has two parts: the mandatory stuff the government and your insurer take, and the stuff you choose to offer to keep good people. Here is every line item you should account for:
| Component | Typical Range | Notes |
|---|---|---|
| FICA (Social Security + Medicare) | 7.65% of wages | Fixed employer share, 6.2% + 1.45% |
| Federal unemployment (FUTA) | 0.6% on first $7,000 | After state credit; roughly $42 per employee per year |
| State unemployment (SUTA) | 1.5% to 4% | Varies by state and your experience rating |
| Workers compensation | 3% to 20% of payroll | Set by trade class code, state, and claims history |
| General liability (labor portion) | 1% to 3% | Premium share allocated to field payroll |
| Health insurance | $3 to $8 per hour | Your actual annual premium per employee, divided by hours |
| Paid time off | 4% to 6% | Vacation, holidays, sick days you pay but do not bill |
| Retirement match, training, tools | Varies | 401(k) match, certification costs, tool allowances |
Notice how much of that list varies by trade and state. A roofer's workers comp rate can be triple a painter's. A contractor in a high-SUTA state pays more than one across the border. That is why a single flat percentage for the whole company is a shortcut that costs money. Build the rate per trade, using your own policy numbers.
The Formula: Annual Cost Divided by Productive Hours
The math is simple once you set it up the right way:
Burdened labor rate = total annual employee cost / productive hours worked per year
Productive hours are not 2,080. A standard year has 2,080 paid hours, but nobody swings a hammer for all of them. Subtract paid holidays, vacation days, and sick days. Most field crews land between 1,850 and 1,950 productive hours. Divide your real total cost by your real productive hours and you get the only honest hourly rate.
Worked Example: A Journeyman Carpenter
Let us run real numbers. This carpenter earns $32 per hour and works full time. The company offers 10 vacation days and 6 paid holidays, pays $12,000 a year for his health coverage, and carries an 8% workers comp rate on carpentry class codes.
Step 1: total annual cost.
- Base wages: $32 x 2,080 hours = $66,560
- FICA (7.65%): $5,092
- FUTA ($7,000 x 0.6%): $42
- SUTA (3% of wages): $1,997
- Workers comp (8%): $5,325
- General liability (2%): $1,331
- Health insurance: $12,000
- Paid time off (16 days x 8 hrs x $32): $4,096
- Total annual cost: $96,443
Step 2: productive hours. 2,080 paid hours minus 128 PTO hours = 1,952 productive hours.
Step 3: divide. $96,443 / 1,952 = $49.41 per hour.
Read that again. The $32 carpenter costs you $49.41 for every hour he stands on the job. If you estimated a 400-hour carpentry scope at $32 an hour, you priced it at $12,800. The true cost is $19,764. That is $6,964 of margin gone before the first board goes up, and no amount of hustle on site recovers it.
Burdened Rates by Trade: What the Numbers Look Like
Every trade has a different comp class, a different wage scale, and a different benefits picture. Here are realistic 2026 ranges built from national median wages with typical burden components applied. Your state and your policy will shift these, which is exactly why you run your own numbers:
| Trade | Typical Base Wage | Typical Burden Range | Typical Burdened Rate |
|---|---|---|---|
| General laborer | $20 to $24 | 28% to 38% | $26 to $33 |
| Carpenter (journeyman) | $28 to $34 | 40% to 55% | $42 to $52 |
| Equipment operator | $30 to $36 | 35% to 50% | $42 to $54 |
| Electrician (journeyman) | $32 to $38 | 42% to 55% | $46 to $58 |
| Plumber (journeyman) | $32 to $39 | 42% to 55% | $46 to $60 |
| Apprentice (any trade) | $18 to $24 | 30% to 40% | $24 to $33 |
The pattern to notice: higher-wage trades carry heavier workers comp and health costs, so their burden percentage runs higher, not lower. Apprentices are your best leverage. Every hour an apprentice works productively at a $28 burdened rate instead of a journeyman at $50 is $22 of margin you kept, as long as the crew mix still delivers the production rates you estimated.
Blended Crew Rates: How Estimators Actually Bid
You rarely bid one person. You bid crews. A blended rate rolls the whole crew into one hourly number so you can multiply it by estimated hours in a single line. Take a typical electrical rough-in crew:
- 1 foreman at $62 burdened x 40 hrs = $2,480
- 2 journeymen at $52 burdened x 40 hrs = $4,160
- 2 apprentices at $30 burdened x 40 hrs = $2,400
- Crew total: $9,040 for 200 crew-hours = $45.20 blended rate
Now your takeoff is simple. If the estimate calls for 600 electrical crew-hours, labor prices at 600 x $45.20 = $27,120. The same logic applies to every trade on the job. When we price general contractor estimates, blended crew rates for each trade go in as separate line items, so the GC sees exactly where labor money sits and can level bids against it trade by trade.
A quick sanity check for your result: multiply the base wage by 1.35. If your calculated burdened rate lands far from that rough factor, audit the line items before you trust them across a bid season. Small shops with full health coverage often land near 1.45 to 1.55, while labor-only subcontractors with minimal benefits land near 1.25 to 1.30. The sanity check catches spreadsheet typos that would otherwise ride along on every bid for months.
5 Labor Costing Mistakes That Eat Your Margin
1. Bidding at the wage rate. The most expensive habit in the industry. Every estimate that prices a $32 carpenter at $32 an hour donates the full burden to the client. Multiply one bad rate across a 2,000-hour year and you have handed away more than $30,000 per employee.
2. Using one flat burden for every trade. A company-wide 30% guess overcharges your laborers and undercharges your electricians. The low trades win bids with too little margin and the high trades lose bids to competitors who priced each trade correctly.
3. Dividing by 2,080 instead of productive hours. Holidays, vacation, and sick days are paid but produce nothing billable. Spreading total cost over phantom hours understates your true rate by 5 to 8 percent.
4. Freezing your rates for years. Workers comp renewals, health premium increases, and wage bumps move every year. A rate built in 2023 is a fantasy in 2026. Recalculate at minimum once a year, and again whenever your insurance renews.
5. Double counting overhead inside the burden. Office rent, estimating software, and your truck fleet belong in company overhead, not in the labor burden. If both the burden rate and the overhead markup carry the same costs, your bids quietly price themselves out of the running.
Prevailing Wage Jobs Change the Math
On Davis-Bacon and state prevailing wage work, the published wage determination already includes fringe benefits, and you must prove you paid them or pay the cash equivalent. Your burdened rate for these jobs is the prevailing wage plus your remaining payroll taxes and insurance on top of it, since FICA, FUTA, and SUTA apply to prevailing wages too. Never bid a prevailing wage job at the determination number alone. Run the full burden on top and keep the certified payrolls clean, because the Department of Labor audits exactly this.
When to Update Your Rates
Build the calculation once in a spreadsheet with each component on its own line, then updating it takes twenty minutes. Refresh it when any of these happen: your workers comp policy renews, health premiums change, you give raises, your state adjusts unemployment rates, or you add or drop a benefit. At minimum, do it every January before bid season. An estimate is only as honest as the labor rate behind it, and a stale rate is a lie you tell yourself.
Frequently Asked Questions
What is a good burdened labor rate percentage?
Most contractors land between 25% and 45% above base wages. Small shops with full health coverage and generous PTO run toward the top of that range. Large union shops with rich benefit funds can run higher still. The only correct number is the one your own payroll produces.
Should I use the same burdened rate for estimating and job costing?
Yes. Using one rate for both is the whole point. When estimates and job costing share the same burdened rates, your actual-vs-estimated labor reports finally tell the truth about which crews and trades make money.
Does the burdened rate include profit and overhead?
No. The burdened rate covers what the employee costs you, nothing more. Company overhead and profit go on top through your markup. Keeping those layers separate is what lets you adjust markup for competitive bids without corrupting your labor cost.
Here is the bottom line. The wage rate is what the employee gets. The burdened rate is what the employee costs. Until your estimates use the second number, you are bidding blind on the biggest cost on most jobs. Run the calculation once with your real payroll data, build burdened rates per trade, and use blended crew rates in your takeoffs. Your margins will notice the difference within a quarter.
