How to price contractor jobs correctly

Most contractors price jobs using one of two broken methods: gut feeling, or cost-plus with the wrong percentage. The correct method accounts for every cost layer, applies overhead proportionally, and builds in a margin — not a markup.

The four cost layers

Every contractor job has four layers of cost. Missing any one of them produces an underbid.

Layer 1: Direct labor

Hours × true burden rate (not wage rate)

Layer 2: Materials

Supplier cost + material handling markup (typically 15–20%)

Layer 3: Subcontractors

Sub quote × markup for coordination and liability (typically 10–15%)

Layer 4: Overhead allocation

Monthly fixed costs ÷ monthly billable hours × job hours

The complete pricing formula

Total Job Cost = Labor + Materials + Subs + Overhead

Price = Total Job Cost ÷ (1 − Target Margin)

Worked example: kitchen renovation

Cost itemCalculationAmount
Direct labor120 hrs × $32/hr burden rate$3,840
Materials$8,200 supplier cost + 18% handling$9,676
Electrical sub$3,500 quote + 12% coordination$3,920
Overhead allocation120 hrs × $22/hr overhead rate$2,640
Total job cost$20,076
Price at 25% margin$20,076 ÷ 0.75$26,768
Profit$26,768 − $20,076$6,692

How to calculate your overhead rate

Your overhead rate converts fixed monthly costs into a per-hour charge applied to every job.

Monthly overhead = all fixed costs that occur regardless of job volume

Overhead rate = Monthly overhead ÷ Monthly billable hours

Example: $8,800/mo overhead ÷ 400 billable hours = $22/hr

Common overhead items:

  • — Vehicle payments and fuel
  • — Insurance (GL, business auto, umbrella)
  • — Tools and equipment depreciation
  • — Owner salary or draw
  • — Office / admin costs
  • — Software and subscriptions
  • — Marketing and advertising
  • — Accounting and legal

Target margin by job type

Job typeTypical rangeNotes
Service calls / T&M40–55%High overhead per job, small scope
Small remodels ($5K–$30K)28–38%High coordination, variable scope risk
Large remodels ($30K+)22–30%Economies of scale, competitive bids
New construction GC15–22%Large subs, thin margins are industry norm
Specialty / licensed trade30–45%Expertise premium, less competition
Landscape install25–35%Material-heavy, weather risk
Recurring maintenance35–50%Low mobilization, repeat work

Check your estimate before sending it

Bid Command takes your total cost and price and tells you whether your estimate hits your target margin — before you send it to a client.
