A PM hire for a commercial subcontractor adds $100K–$155K in loaded overhead immediately — a 1.6–2.4% overhead rate increase for a $5M sub. Break-even at 22% gross margin requires $590K in additional revenue. Revenue lift typically takes 3–6 months to materialize, creating a cash flow and margin squeeze during the transition. SPM models PM hires before they happen and updates the job costing overhead structure after.

Growth Stage Decision

Your First PM Hire Costs More Than The Salary. Here's the Full Math.

Hiring a project manager feels like a growth move. Financially, it's an overhead event — $100K+ in new fixed cost that hits the P&L on Day 1. The revenue that justifies it takes 3–6 months to materialize. Most subcontractors make this hire without running the numbers first. SPM runs the analysis before the decision — loaded cost, break-even revenue, cash flow through the transition, and what happens to the overhead rate and bid markup the day the PM starts.

The Financial Reality

What a PM Hire Actually Does to Your Numbers.

01
Overhead Jumps $80K–$120K Immediately
A PM hire is an overhead event. Day 1 of employment, the P&L shows a new fixed cost — salary, burden, benefits. For a $5M subcontractor this represents a 1.6–2.4% increase in overhead rate. Gross margin gets pressured immediately. The revenue that justifies it takes months to materialize.
02
Revenue Lift Takes 3–6 Months
The owner hiring a PM to free up time for sales and new contract pursuit doesn't generate revenue on Day 1. New jobs take time to bid, win, contract, and mobilize. The financial gap between the overhead increase and the revenue increase is typically 3–6 months — which creates a cash flow and margin squeeze during the transition.
03
The Overhead Rate Model Needs to Be Rebuilt
If the owner was managing projects personally, that cost was buried in owner compensation — not allocated to jobs. A PM hire makes project management a trackable overhead cost. If you don't recalculate your overhead rate after the hire, your job margins will look artificially healthy while the company P&L shows the burden.
How to Model It Right

Analyze the Hire Before You Make It.

Calculate the Loaded Cost
Base salary + FICA + benefits + workers comp + overhead allocation
Typical total: $100K–$155K for a commercial sub PM
Don't use base salary alone — the fully loaded number is what matters
Model the new overhead rate as a percentage of projected revenue
Calculate the Break-Even Revenue
Loaded PM cost ÷ gross margin % = break-even revenue needed
At 22% GM: $130K ÷ 0.22 = $590K additional revenue required
Identify where that revenue comes from before the hire
Model the timeline to reach break-even — 6 months? 12?
Update the Job Costing Structure
Recalculate overhead rate to include PM labor
Allocate PM time to active jobs as project overhead
Adjust bid overhead markup to reflect new overhead base
Monitor margin impact on jobs bid before vs. after the hire
Making the Call

How to Know If the Hire Is Justified.

The PM hire decision isn't just a financial model — it's a capacity model. The question isn't whether you can afford the PM. It's whether the owner's freed-up time generates enough incremental revenue to justify the overhead increase — and whether the cash position can absorb the 3–6 month lag before that revenue materializes.

SPM runs this analysis before clients make significant hires. We model the loaded cost, the break-even revenue, the cash flow impact during the transition, and the overhead rate change. If the hire is justified, you go in with a plan. If the timing is wrong, you know when it will be right.

Model the fully loaded PM cost — not just base salary
Identify specifically how the owner's freed time will generate revenue — concrete, not theoretical
Confirm the line of credit can absorb 6 months of overhead increase before revenue lift
Recalculate overhead rate immediately after hiring — update job cost structure and bid markups
Set a 12-month break-even target and track it monthly in the CFO review
Frequently Asked Questions

Common Questions.

A PM for a commercial subcontractor typically costs $80K–$120K in base salary plus $20K–$35K in burden and overhead — a total loaded cost of $100K–$155K per year. That's a 2–3% overhead rate increase for a $5M subcontractor. The cost is immediate; the revenue benefit takes 3–6 months.

When the owner is managing more than $3M–$4M in work personally and can't pursue new contracts because they're buried in project management. The key is modeling the revenue lift vs. the overhead increase before making the decision — not after.

If a PM costs $130K loaded and your gross margin is 22%, the PM needs to enable $590K in additional revenue to break even on overhead. The break-even timeline is typically 6–12 months — meaning the cash position needs to absorb the overhead increase for up to a year.

A PM hire changes the overhead allocation model — project management labor that was previously owner time becomes a direct overhead cost that should be allocated to jobs. SPM reconfigures the job costing overhead rate after significant hires to keep job margins accurate.
