Commissions are one of the most contentious topics in construction management. Pay too little and your best project managers leave. Pay too much and your margins evaporate. Use a confusing formula and your PMs spend more time questioning their paychecks than closing deals.
The goal is a system where every PM can look at a job and calculate their own commission within sixty seconds. If they need an accounting degree to understand their comp plan, you have already failed.
Why Revenue-Based Commissions Destroy Margins
The simplest commission model is a flat percentage of contract value. This is easy to understand but creates a dangerous incentive. PMs are rewarded for selling volume, not profitability. A PM who sells a $200K job at a 15% margin earns the same commission as one who sells a $200K job at a 40% margin, even though the second deal is worth dramatically more to the company.
Worse, revenue-based commissions encourage underbidding. A PM who wants to close quickly can shave the price, knowing they still earn a commission while the company absorbs the margin hit. Over time, this erodes your average sell ratio and trains PMs to compete on price rather than value.
The Gross Profit Model: Aligning PM Incentives with Company Health
A healthier approach ties commissions to gross profit rather than revenue. The formula is straightforward: take the contract value, subtract direct costs (subcontractor payments, materials, permits), and apply the commission percentage to what remains. This means PMs earn more when they sell profitably and less when they leave money on the table.
A typical structure for a mid-size remodeling company: the PM is charged a “lead cost” of 20-25% of the gross contract value (covering marketing, overhead, and office support). Their commission is then calculated as a percentage of the remaining gross profit after lead cost and direct expenses.
The key advantage is transparency. When a PM can see exactly what drives their take-home pay, they start caring about sub costs, material markups, and scope accuracy because those numbers directly affect their wallet.
Handling Multi-PM Splits and Change Orders
Jobs with multiple PMs add complexity. The fairest approach is to define each PM's role upfront—who sold the job (lead PM), who manages construction (production PM)—and split the commission pool accordingly. A common split is 60/40 favoring the selling PM.
Change orders deserve their own commission treatment. Pre-construction change orders should carry the same commission structure as the original contract. Construction change orders often have higher margins because the crew is already mobilized, so the PM earns proportionally more.
Making It Work: Automation and Transparency
Even the best commission formula fails if PMs cannot see their numbers in real time. Waiting until month-end to calculate commissions creates anxiety and distrust. A PM who thinks they are owed $8K but receives $6.2K will immediately assume the calculation is wrong, even if it is correct.
The fix is a live commission dashboard where PMs can see, for every job: the contract value, the lead charge, direct costs paid to date, gross profit to date, and their earned amount. When a sub payment is released or a material invoice is posted, the commission number updates immediately. No surprises at payroll.
