How plumbing contractors split crew and subcontractor costs on a job
When a job runs on a mix of your own crew and subcontractors, one blended number hides where you actually make money. Subs are a cost you mark up and pass through; your crew is a cost you carry against the contract price. Splitting the job by party shows which subbed scopes are padding your margin and whether your in-house labor is actually paying off.
This calculator uses the standard job-costing method: each subcontractor is billed at cost × (1 + markup), materials the same, and the revenue left after those scopes is what covers your crew’s labor and margin. It keeps markup and margin straight — markup is measured on cost, margin on the bill, converted only with the divisor method (a 20% markup is a 16.7% margin) — so the per-party numbers are honest. Use it with the Job Pricing and Bid calculators to price the whole job, then this tool to see how the profit splits.

How do I split job costs between my crew and a subcontractor?
Treat the sub as a marked-up pass-through: bill = sub cost × (1 + your markup). Your crew is your own cost — hours × loaded rate. The revenue left after the subbed and material scopes are billed is what covers your crew’s labor and your margin on the in-house work. The tool does this automatically and shows the margin on each.
What is the difference between markup and margin on a sub?
Markup is measured on the sub’s cost; margin on what you bill. A 20% markup on a $5,000 sub bills $6,000 and keeps $1,000 — which is a 16.7% margin, not 20%. This calculator reports markup on cost and margin on the bill so you don’t confuse the two and underprice subbed work.
What markup should I add to subcontractor work?
Most contractors add 15–25% to subbed scopes (20% is the common default), covering the risk, coordination, and warranty you take on by putting the sub under your contract. Specialized or higher-risk scopes run higher; simple pass-throughs sometimes lower.
Is this crew cost split calculator free?
