Estimating

What is markup in construction?

Markup is the percentage added on top of a job's cost to arrive at the selling price. It has to cover company overhead and leave a profit.

Markup is what you add to cost to get price. If an estimate shows $100,000 in labor, material, equipment, and subs, and you apply a 20 percent markup, you bid $120,000. That extra $20,000 pays for the office, the estimator's salary, insurance that is not charged to jobs, and whatever is left is profit. Markup is always figured as a percentage of cost.

The word gets used loosely. Some contractors mean the whole add-on. Others split it into separate overhead and profit lines, as many change order clauses require. Know which one you are talking about before you agree to a number.

Markup versus margin

This is where money disappears. Markup is measured against cost. Gross profit margin is measured against price. The same dollars give two different percentages.

Markup and the margin it produces
Markup on costPrice on $100,000 costGross margin on price
10%$110,0009.1%
15%$115,00013.0%
20%$120,00016.7%
25%$125,00020.0%
33.3%$133,33325.0%
50%$150,00033.3%

The formulas: markup equals margin divided by (1 minus margin). Margin equals markup divided by (1 plus markup). If your financial statements say you need a 20 percent gross margin to cover overhead and make money, you need a 25 percent markup, not 20. The guide on markup vs margin in construction has more examples.

How markup works on a real job

Say a remodeler runs $1.5 million a year in revenue with $210,000 in annual overhead, which is 14 percent of revenue. The owner wants 8 percent net profit. That means the company needs a 22 percent gross margin on every job, which takes a markup of about 28.2 percent on cost.

A kitchen job estimates at $62,000 in direct cost. At 28.2 percent, the price is about $79,500. Gross profit is $17,500, or 22 percent of the price. If the remodeler had used a 22 percent markup by mistake, the price would be $75,640 and margin would be about 18 percent, short of what the business needs by roughly $3,840 on this one job.

Markup does not have to be one number. Many contractors use a lower rate on subcontracted work, where their risk is smaller, and a higher rate on self-performed labor, where productivity can swing the cost.

Common mistakes

  • Confusing markup with margin. The most common and most expensive error.
  • Marking up unburdened labor. If labor in the estimate is base wage only, the markup has to cover labor burden too, and usually does not.
  • Using a markup from another company. Your overhead is your own. A rule of thumb from someone with half your office staff will not fit.
  • Ignoring contract limits. Cost-plus and T&M contracts often cap the fee or the markup on change orders. Price inside those rules.
  • Not rechecking it. If overhead grows faster than revenue, last year's markup quietly stops working.

Markup connects to profit margin, net profit margin, fee, and indirect costs. Smart Business Automator shows bid margin next to actual job cost, so you can see whether the markup you set is holding as the work goes in. See job costing and WIP automation.

Frequently asked questions

What is a good markup for a contractor?

One that covers your actual overhead and your profit target. Work it backward from your financial statements instead of copying a standard percentage, since overhead differs a lot between companies and trades.

Is a 20 percent markup the same as a 20 percent profit?

No. A 20 percent markup on cost produces about 16.7 percent gross margin on price, and that margin still has to pay overhead before any net profit is left.

Should markup be applied to subcontractor costs?

Usually yes. You carry risk, coordination, and payment exposure on sub work. Many contractors use a lower markup on subs than on self-performed work.

How is markup handled on change orders?

Check the contract. Many prime contracts and subcontracts set a specific overhead and profit percentage for change orders, sometimes different for added and deducted work.
