Labor Markup Calculator
If you charge $50 an hour and it costs you $40, is your profit 25% or 20%? Both, depending on what you measure against, and that confusion costs contractors real money. This labor markup calculator prices labor three ways: mark up a base labor cost, solve the markup needed to hit a target profit margin, or build a fully loaded billable rate from wage, labor burden, overhead and profit.
Materials, travel, permits added after markup.
Quick Answer
A $25 base labor cost with a 50% markup charges out at $37.50, and that 50% markup is only a 33.33% margin on the price. To earn a true 20% margin on a $40,000 job you must charge $50,000, a 25% markup. And a $35/hr wage with 35% burden, 20% overhead and a 15% profit margin bills at $66.71/hr. The calculator above is pre-filled with these exact examples, one per mode.
Key takeaways
- Markup divides profit by cost; margin divides profit by price. The same dollars always produce a bigger markup number than margin number.
- Price from your margin target, not a markup habit: divide cost by (1 − margin). A 20% overhead load needs a 25% markup just to break even.
- Your wage is not your cost. BLS data put private-industry benefits at 30.0% of total compensation in June 2026, before overhead enters at all.
- Pass-through costs added after markup dilute your real margin. The tool’s real margin row shows the diluted figure, not the flattering one.
How to use the labor markup calculator
Pick the mode that matches the decision in front of you. The three modes share one results box, and switching modes hides the previous result.
- Markup on cost: enter a base labor cost and a markup percentage. You get the charge-out rate, the markup amount, and the real margin on the price. The optional additional costs field adds pass-through items (materials, travel, permits) after the markup; they raise the client’s total but add no profit, so watch the real margin row fall when you use it. Marking up labor alone is only half a bid: the labor burden calculator works out the true cost that belongs in the base field.
- Hit a target margin: enter the total job cost and the margin you want to keep. The tool returns the selling price and the markup that produces it. This is the mode to use when you think in margins, which is how your accounts and your tax return see the job.
- Loaded hourly rate: enter the wage, burden percentage, overhead percentage and target profit margin. The tool stacks them in order and returns the billable rate, with each layer shown. If you run a crew at different skill levels, run this mode once per level; the blended labor rate calculator then averages a mixed crew into one rate.

Markup is not margin: the formulas
Markup is measured against your cost; margin is measured against the price the client pays. That one change of denominator is the whole trap, and every formula on this page follows from it.
Margin = Profit ÷ Price × 100
Price from margin = Cost ÷ (1 − Margin ÷ 100)
Markup needed for a margin = Margin ÷ (100 − Margin) × 100
Loaded billable rate = Wage × (1 + Burden ÷ 100) × (1 + Overhead ÷ 100) ÷ (1 − Profit margin ÷ 100)
A $10,000 job cost with a 25% markup prices at $12,500; the $2,500 profit is a 20% margin, not 25%. Contractors who “add 20% for profit” are actually earning a 16.67% margin (20 ÷ 120). The conversion table below is the one to pin above the desk; every row was run through the target-margin mode above.
| Target margin on price | Markup needed on cost | Price per $1,000 of cost |
|---|---|---|
| 5% | 5.26% | $1,052.63 |
| 10% | 11.11% | $1,111.11 |
| 15% | 17.65% | $1,176.47 |
| 20% | 25.00% | $1,250.00 |
| 25% | 33.33% | $1,333.33 |
| 30% | 42.86% | $1,428.57 |
| 40% | 66.67% | $1,666.67 |
| 50% | 100.00% | $2,000.00 |
Read the same relationship from the other direction and the gap widens as the numbers grow: a 10% markup yields a 9.09% margin, a 25% markup yields 20.00%, a 50% markup yields 33.33%, and even a 100% markup, doubling your cost, yields only a 50.00% margin.
Worked examples: all three modes, verified
Each mode is pre-filled with one of these runs, so the first click on Calculate reproduces the row exactly.
| Mode | Inputs | Headline result | Key detail |
|---|---|---|---|
| Markup on cost | $25 cost, 50% markup, $0 additional | Charge-out $37.50 | Markup $12.50; real margin 33.33% |
| Markup with pass-through | $1,000 cost, 25% markup, $200 additional | Total $1,450.00 | Real margin falls to 17.24% |
| Hit a target margin | $40,000 cost, 20% target margin | Sell at $50,000.00 | Markup needed 25.00%; profit $10,000 |
| Loaded hourly rate | $35 wage, 35% burden, 20% overhead, 15% margin | Billable $66.71/hr | True cost $47.25; with overhead $56.70 |
The second row is the one to study. The markup itself did not change between rows one and two, but passing $200 of costs through at zero markup cut the real margin from the 20.00% a bare 25% markup would give to 17.24%. If pass-through items dominate your jobs, price them with their own smaller markup instead of letting them dilute the labor margin silently. What is left after costs is the gross profit share; the gross profit rate calculator expresses that same leftover as a rate on revenue, and the 20 percent margin calculator isolates the most common single target.
Building a loaded rate, step by step
A loaded rate is built in four layers, and the order matters: burden on the wage, overhead on the burdened cost, profit as a margin on the final price.
Layer 1, burden. The employer’s share of Social Security and Medicare alone is 7.65% of wages, per the IRS guidance on Social Security and Medicare withholding rates, before unemployment insurance, workers compensation, health cover, retirement contributions and paid time off. Across the whole private sector, the BLS Employer Costs for Employee Compensation release for June 2026 put benefits at $14.07 of a $46.89 hourly total, 30.0% of compensation, and construction trades with higher workers compensation rates sit above that average. The US Small Business Administration’s rule of thumb in How Much Does an Employee Cost You?, a total cost of 1.25 to 1.4 times salary, is the same reality seen from the annual side.
Layer 2, overhead. Rent, trucks, fuel, tools, software, insurance and the owner’s own salary have to come out of billed hours, and only billed hours. Express overhead honestly as a percentage of burdened labor cost, from your own accounts: total annual overhead ÷ total annual burdened labor cost. Guessing here is where loaded rates quietly go wrong.
Layer 3, profit as a margin. The build-up divides by (1 − margin) instead of multiplying by (1 + markup), and the difference is not pedantry: on the worked example, a 15% markup on $56.70 gives $65.21, which leaves only a 13.04% margin, while the margin method gives $66.71 and the full 15%. Benchmarks say the margin is worth defending: the NAHB Cost of Doing Business Study reports average builder gross margins of 20.7% of revenue and remodeler gross margins of 29.9% in 2024, numbers that are impossible to reach by pricing with markups mistaken for margins. Once the rate is set, the effective labor rate calculator checks what your shop actually realizes per billed hour after discounts and write-downs.
What competing tools miss
The contractor markup pages that rank are better written than most calculator content, and several still trip on the exact confusion this page exists to fix:
- InstantSalesFunnels contractor guide: its own loaded-rate example contradicts itself twice. The summary claims a $35 wage with 35% burden, 20% overhead and 15% profit bills at $65.21/hr; the worked steps then say $66.91/hr. Both are wrong, and in instructive ways: $65.21 is what you get by applying profit as a 15% markup instead of a margin, and $66.91 matches neither method. The correct figure, from the build-up above and reproduced in the calculator, is $66.71/hr.
- SmartBizCalc: a genuinely strong benchmark page, but it defines contractor markup as “profit ÷ cost × 100” in its quick answer, which is the formula for markup percentage only when the starting figure is pure cost; applied to a price that already includes overhead recovery, it mislabels the result. Its margin table and NAHB sourcing are good; its headline definition needs the cost base stated.
- Job Cost Pro: the cleanest simple rival: cost and markup in, price, profit and real margin out. It stops there. No target-margin solver, no loaded-rate build-up, and no treatment of pass-through costs.
- EstimateKit HVAC calculator: excellent margin table for one trade, but the workflow is HVAC equipment pricing; labor is one line among materials, and there is no burden or overhead layering for the labor itself.
- TradesMetrics: a thoughtful per-category markup guide with a static worked table, but the interactive tool is a signup product; the public page never lets you run your own loaded rate.
- The gap this page fills: all three pricing decisions in one free tool, the real (diluted) margin shown when pass-through costs are added, and a loaded-rate example whose arithmetic actually survives checking.
Frequently asked questions
There is no standard number: your markup must cover your overhead and leave real profit, so it comes from your books. Know your overhead as a percent of revenue, then price so your margin (not markup) clears it. A 20% overhead needs a 25% markup just to break even.
Markup % = margin % / (100 – margin %) x 100. A 20% margin needs a 25% markup; a 30% margin needs 42.86%. The “Hit a target margin” mode does this for any numbers.
A margin on the selling price. Adding 20% to cost gives a 16.67% margin; dividing cost by (1 – margin) gives the true 20%. Use the margin mode above.
Everything employment costs beyond the wage: employer payroll taxes, workers compensation, unemployment insurance, benefits, and paid time off. For US contractors it typically adds 25 to 40% on top of the hourly wage.
Because margin divides by the bigger number (price). Markup of m% always equals a margin of m/(100+m): 50% markup = 33.33% margin, 100% markup = 50% margin.
Additional costs are added after the markup, at cost, with no profit on them. They raise the total the client pays, and the real margin row divides the markup amount by that full total, so pass-through costs dilute the margin the result shows.
No. A 100% margin would mean the entire price is profit and the cost is zero, which requires dividing by zero. The calculator rejects target margins of 100% or more in both the margin mode and the loaded-rate mode.
After burden. The build-up is wage x (1 + burden), then x (1 + overhead), then divided by (1 – profit margin). Applying overhead to the burdened cost matches how contractor cost build-ups are usually sequenced, and every layer is shown separately in the results.
