SETTING THE RIGHT MARKUP is one of the most important financial decisions a commercial construction contractor can make. Markup isn’t just a percentage added to the cost of a project. It is a reflection of cash management, overhead recovery, and profit strategy.
Oftentimes, many contractors treat markup as a simple “add-on” without considering how different types of markup impact cash flow, project profitability, and long-term business growth.
We have reviewed the difference between margin and markup in previous articles. Here we will address different types and factors to consider when determining your markup.
Cost-Plus Markup
The most common method is a cost-plus markup, where a contractor adds a fixed percentage to the direct costs of labor, materials, and subcontractors. In commercial construction, subcontractors often rely on cost-plus markup to cover project costs and ensure profit, but the percentages vary depending on several factors: risk, overhead, project size, and market conditions. Below are some basic cost-plus markup percentages commercial contractors use, and why that number was determined:
Direct labor and materials: 10–20% markup is common.
Why: This covers basic overhead and provides a reasonable profit margin on routine, predictable costs. Smaller, less complex jobs may see higher percentages because fixed overhead (office staff, insurance, equipment) is harder to spread across a small project.
Subcontracted trades: 5–15% markup is often applied.
Why: Contractors pass some of the responsibility to their own trades but still need to cover their coordination, risk, and administrative oversight.
Cost-plus markup is straightforward and ensures all project costs are covered, plus a consistent profit margin. However, it doesn’t always account for indirect costs like administrative overhead, equipment depreciation, or project management time unless those costs are explicitly included in the base cost.
Fixed-Price Markup
Fixed-price markup involves quoting a single, lump-sum amount for the project, typically based on estimated costs plus an anticipated margin. This method is common in commercial construction where clients expect a guaranteed price upfront.
The advantage of a fixed-price markup is predictability for the client and the potential for higher profit if the contractor manages costs efficiently. The downside is that unexpected cost overruns, such as delays, material price increases, or scope changes which can erode profit. Contractors must build contingency buffers into the markup to protect themselves.
Tip from our experts: Never judge your price on what you think other contractors are charging. This can wreak havoc on your finances because you have no idea what their costs, expenses or labor rates are.
Sliding-Scale Markup
Sliding-scale markup varies depending on project size, complexity, or risk. A contractor may apply a higher markup to smaller, high-risk jobs to offset overhead costs and a lower markup to larger, lower-risk projects where economies of scale apply.
For example a subcontractor handles two types of projects in the same month:
- Small construction project: $50,000 total cost, tight timeline, and higher coordination per dollar spent.
- Large commercial build-out: $1,000,000 total cost, predictable workflow, and lower relative overhead per dollar.
Without sliding-scale markup:
- The contractor applies a flat 10% markup to both projects.
- The small job billed at $55,000 which is a small profit but high relative overhead absorbed.
- The large job billed at $1,100,000 which provides them with a larger profit, but relative overhead recovery is easily covered.
Problem: The small job barely covers overhead, even though it requires almost as much administrative effort per dollar as the large job.
With sliding-scale markup:
- Small job markup increased to 20%. Overhead and risk are covered, and the project is profitable.
- Large job markup lowered to 8%. Overhead is already covered by volume, so a smaller percentage is sufficient, keeping the bid competitive.
This approach can maximize profitability across a portfolio of projects, but it requires careful tracking and understanding of cost behavior. Miscalculating the sliding scale can result in undercharging on projects that look “big” but have hidden risks.
Risk-Adjusted Markup
Risk-adjusted markup accounts for unique project risks, such as schedule uncertainty, site complexity, or volatile material prices. Contractors assess the likelihood of unforeseen costs and adjust their markup to protect the project’s profitability.
This is particularly important in commercial construction, where projects are large, complex, and subject to regulatory and logistical challenges. Contractors who ignore risk-adjusted markup may win work but lose money when complications inevitably arise.
How to decide which is best for you
Understanding the different types of markup is essential for building a financially healthy construction business. Cost-plus, fixed-price, sliding-scale, and risk-adjusted markups each serve different purposes and can be applied strategically depending on the project, client expectations, and cash flow needs.
Smart contractors know that markup isn’t just about winning the bid, it’s about sustaining the business, covering overhead, managing risk, and creating predictable profit margins. By combining the right markup strategy with careful project planning and funding, construction companies can grow confidently, even in a complex, competitive market.
