Garage Door Business Profit Margin: IRS Data, Costs & Break-Even

By Muhammet Çay

What does garage door profit margin measure?

Gross margin is sales minus the direct cost of doors, openers, springs, other parts, and field labor, divided by sales. Net margin also subtracts van expenses, insurance, scheduling, marketing, software, and other overhead. A markup on a spring is calculated against its cost; margin uses the customer’s price as the denominator. Use the markup versus margin calculator before setting a parts markup.

For an owner working service calls, the amount left after business expenses partly compensates that labor. Calling it passive profit overstates what the business earns independently of the owner. The IRS table below pools all specialty trades, including work far outside garage doors; it cannot establish the margin for a repair call or a complete installation.

Where does the money go?

Door replacements commit the shop to larger purchased materials and delivery coordination. Spring and opener repairs may have a smaller materials bill, but diagnosis, dispatch, and a return trip can consume the apparent spread. Track gross profit separately for repairs and installations, then examine callbacks by cause. A warranty visit should carry its technician time and travel even when the invoice is zero.

Labor needs its own line. The BLS May 2025 national median wage for mechanical door repairers, a best-match occupation, is $26.79 per hour (official wage data), not a billable rate or total employer cost. The trade data lists $608 per month for a selected bundle of insurance median premiums (estimate); actual coverage and quotes vary. Van fuel, maintenance, and time between calls also matter. For vehicle planning, the IRS business mileage rate effective July 2026 is 76 cents per mile (official tax rate), which is a deduction rate rather than a shop operating-cost survey.

A garage door job example

Example inputs, not a benchmark: Suppose a door installation brings in $2,400. The door and hardware cost $950, paid installation labor costs $400, and delivery and disposal cost $100. Direct cost is $1,450, leaving $950 gross profit; $950 ÷ $2,400 = 39.6% gross margin. Allocate $350 of monthly overhead to this job and reserve $100 for follow-up work. The remaining $500 gives $500 ÷ $2,400 = 20.8% net margin before income tax and before any pay for an owner who performed the installation. These inputs belong to this example alone.

Enter actual invoices and costs in the profit margin calculator. For a wider operating plan, compare opening equipment and cash needs in garage door startup costs, and check the scope of work under garage door licensing.

How many jobs cover overhead?

Calculate contribution per job as price minus variable parts, labor, and delivery. Divide monthly fixed costs by that contribution, then round up to a whole completed job. Repeat the calculation for a repair-heavy schedule and an installation-heavy schedule; one blended ticket can hide a loss-making service line. Use the jobs needed calculator and break-even calculator. The garage door hourly rate guide helps price labor separately.
