How do you calculate fabrication quote gross margin?

Divide gross profit by the selling price and multiply by 100. A $3,200 profit on a $12,500 quote is 3,200 / 12,500 x 100 = 25.6 percent gross margin.

What is a good gross margin on a fabrication quote?

Many fab shops target 30 to 40 percent gross margin to cover overhead and leave net profit. At 25.6 percent, this quote sits 4.4 points below a 30 percent target, so it is on the lean side.

Margin vs markup, what is the difference?

Margin is profit as a percent of selling price (25.6 percent here); markup is profit as a percent of cost. The same $3,200 profit on $9,300 cost is a 34.4 percent markup but only a 25.6 percent margin, so do not confuse the two when quoting.

Why is my quote below target margin?

Usually material priced too low against rising steel, underestimated weld and fit-up hours, or a discount given to win the job. The 4.4-point gap here flags that something in the estimate is eating into the target.

How do I raise a fabrication quote's margin?

Either raise the selling price or cut cost through better nesting, less rework, or faster weld processes. To hit 30 percent on this $12,500 quote you would need about $3,750 of gross profit, $550 more than the current $3,200.

Does gross margin mean the job is profitable?

Not by itself. Gross margin ignores overhead and SG&A. A 25.6 percent gross margin only becomes net profit after the shop covers rent, equipment, and admin, so a thin gross margin is a warning sign.

Welding & Fabrication calculator

Fabrication Quote Margin Calculator

Fabrication quote gross margin is the percentage of a quoted job's selling price that remains as gross profit after material and labor cost. Estimators and shop owners in welding and metal fabrication use it to check that a quote clears the shop's target margin before it goes out the door. It matters because fab work has thin, variable margins: steel price swings, weld time overruns, and aggressive competitors can quietly push a quote below the margin the shop needs to stay healthy. This calculator gives a one-glance check of where a quote sits and how far it is from target.

What this calculator does

Calculate fabrication quote gross margin from gross profit dollars and quoted selling price, with gap to the target margin.
Use it on every fab quote before sending to confirm the gross margin clears the shop target after material, labor, and burden are loaded.
It computes the gross margin percentage of a fabrication quote from gross profit and selling price, then shows the gap in points to your shop's target margin.

Formula used

Fabrication quote gross margin = gross profit on the quote ÷ quoted selling price × 100
Margin gap to shop target = fabrication quote gross margin - target gross margin

Inputs explained

Gross profit on the quote: Quoted selling price minus total cost: materials, labor with burden, consumables, outside processing.
Quoted selling price: Final quoted price to the customer, including any markup or freight pass-through.
Target gross margin: Shop margin policy. Common job shop targets 25 to 40 percent; specialty fab 35 to 55 percent.

How to use the result

Use it on every quote before release, and when reviewing won jobs to see whether actual margins held against target.
It works on gross margin only, so it ignores shop overhead, SG&A, and whether the job actually runs to estimate; a healthy gross margin can still lose money if overhead is high.

Current U.S. benchmarks

The producer price index for steel mill products stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
