How the flat rate price is calculated
The calculator first builds a cost base: labor hours times loaded labor rate, plus parts, overhead recovery, and a callback reserve. It then divides that cost base by one minus your target gross margin. This avoids the common mistake of treating markup and margin as the same thing.
Current flat-rate pricing tools for service businesses use the same general cost build-up: real labor time, loaded labor cost, parts, overhead, and profit target. This page uses user-entered assumptions instead of defaulting to a trade-specific price book.
Worked example
With 2.5 labor hours at $82 per hour and $115 in parts, direct cost is $320. Adding 18% overhead and a 6% reserve brings the cost base to about $397. To hit a 55% gross margin, the fixed customer price is about $881 before any rounding policy.
When to use this tool
- Use it when you know the labor hours and parts for a repeatable service task.
- Use the minimum charge floor for dispatch-heavy or diagnostic jobs that should never price below a trip charge.
- Do not use it as a replacement for required licenses, safety rules, manufacturer procedures, or warranty terms.

Frequently asked questions
What is a flat rate pricing calculator?
A flat rate pricing calculator builds one customer-facing job price from labor time, loaded labor cost, parts or materials, overhead recovery, risk reserve, and a target gross margin. It helps service contractors quote a fixed price instead of billing every job strictly by the hour.
Is flat rate pricing the same as markup?
No. Markup is profit divided by cost, while gross margin is profit divided by selling price. A 60% target margin requires price = cost / 0.40, not cost times 1.60.
What should I enter for loaded labor rate?
Use the hourly cost of the technician after wages, payroll taxes, benefits, workers compensation, vehicle time, and other labor burden you want carried by the task. If you only know base wage, calculate a loaded labor rate first.
Does this replace a trade flat rate manual?
No. This calculator prices a task from your own labor hours and cost assumptions. It does not provide proprietary labor-unit books, manufacturer repair times, warranty policies, or trade-specific diagnostic rules.
Why include callback reserve?
Flat rate service work needs room for warranty callbacks, small parts variance, travel friction, and occasional underestimated tasks. A small reserve can keep one bad job from erasing the margin on the whole book.
