How we got this

  1. Job cost$1,200 materials + $900 labor + $150 other = $2,250
  2. Gross profit$3,500 − $2,250 = $1,250
  3. Gross margin$1,250 ÷ $3,500 price = 35.7%
  4. Markup$1,250 ÷ $2,250 cost = 55.6%
  5. Overhead share15% of $3,500 = $525
  6. Net profit$1,250 − $525 = $725 (20.7%)

Windows and Doors profit margin benchmarks

The IRS reports what one-owner businesses filing Schedule C earn, by sector. Windows and Doors falls under Specialty trade contractors. For tax year 2023, 2,521,516 returns reported $257.8 billion in receipts, $80.4 billion in cost of sales and $40.5 billion in net income less deficit (the table gives thousands of dollars):

Gross margin68.8%
Net margin, owner pay included15.7%
Average receipts per return$102,220
Average net income per return$16,054

The owner's own draw is not an expense on a Schedule C, so that net margin is mostly the owner's wage, not profit on top of it.

Where the money goes in window and door

Window and door jobs are product heavy: the units are most of the price, with labor, trim and haul away on top. Rot found when the old unit comes out is the hidden cost.

Where window and door margin leaks, and how to win it back

  • Rot and framing repairs found on removal
  • Ordering errors that mean a second trip
  • Trim and finish work left off the quote
  • Haul away of old units
  • Units sold at cost

Ways window and door installers raise margin: price rot repair per foot on the estimate; measure twice and order once; sell trim and finish work with the install; mark up the units.

Check your window and door prices against the costs

The typical national prices from our sourced calculators are a check on whether your prices leave room for margin:

ServiceTypicalRange
Replacement window, installed$750$350 to $1,100 a window
Egress window, below grade$4,150$2,600 to $5,650 a window
Skylight, installed$1,500$1,050 to $2,000 a skylight
Glass only, double pane$463$200 to $725 a pane
Steel entry door, installed$1,163$325 to $2,000 a door
Fiberglass entry door, installed$2,575$350 to $4,800 a door

Work out the margin on each line of your menu, not just the big jobs. The usual window and door menu: replacement window, installed; egress window, below grade; skylight, installed; glass only, double pane; steel entry door, installed; fiberglass entry door, installed; two-panel sliding glass door; interior prehung door; window balance and hardware repair; door adjustment and weatherstripping; rotted sill and frame repair.

Overhead comes out of the margin before profit. In window and door it includes general liability insurance, which Insureon's customers who are door and window installers pay an average of $96 a month for; commercial auto at $298 a month on the same figures.

Work out your own margin

Put one recent window and door job into the calculator above, or switch it to "My margin for the year" to set your year next to the IRS benchmark. A 50% markup is a 33% margin; the markup calculator shows the rest.
