Flat-rate prices for good, better, best
Build three options for the same job from hours, parts and your markup, and see what each one leaves you after labor and parts. Works for HVAC, plumbing, electrical and roofing tasks.
Price = hours × labor rate + parts × (1 + markup) + trip fee. Margin = (price − hours × labor cost − parts cost) ÷ price. If your labor cost is the cost per billable hour (with truck and overhead in it), this margin is close to your net margin.
A flat-rate price is task hours × your labor rate, plus parts × (1 + parts markup), plus any trip or diagnostic fee. For good, better, best, price each option the same way. At $249 an hour, a 1.5-hour repair with $60 of parts at 100% markup is $493.50, about $495. Check each tier's margin against your labor cost, not the wage.

What the flat-rate price calculator does
Three tiers side by side
Good, better and best priced with the same method, so the middle option makes sense.

Flat-Rate Price Calculator FAQ
How do you calculate a flat rate price?
Multiply the hours the task usually takes by your labor rate, add the parts at cost times one plus your parts markup, and add any trip or diagnostic fee. The customer pays that price whether the job runs short or long, so the hours should be your real average.
What's the difference between labor rate and labor cost here?
Labor rate is what you charge per billable hour. Labor cost is what that hour costs you: wage, burden, truck and overhead divided by billable hours. The calculator prices with the rate and measures margin with the cost.
How should good, better, best options differ?
By what the customer gets: repair versus replacement, standard versus upgraded equipment, a longer warranty or extras such as a surge protector or a maintenance visit. Our good, better, best guide shows how to build tiers so the middle one sells.
What parts markup should I use?
There's no single rule. Many shops mark up small, cheap parts much more than expensive equipment, so a $10 fitting might carry 100% or more and a $3,000 unit far less. Whatever you pick, check the tier's overall margin here.
Should the trip fee be part of the flat rate?
That's your call. Some shops charge a diagnostic fee and credit it to the repair, others build drive time into every flat rate. Leave the fee at zero if it's already in your hours.
Can I put these prices into CrewRobin?
Yes. CrewRobin's price book holds labor, parts and flat-rate services on every plan, and you add them to good, better, best quotes the customer picks and signs online.
