Markup & Margin Calculator for Construction

Markup strategy in construction is more nuanced than most industries because you are pricing multiple cost components — materials, labor, subcontractors, and equipment — each with its own margin profile. A well-run general contractor applies different markups to different cost categories: materials typically get 10–15% markup (slim because clients can price-check), labor gets 30–50% markup (your crews are your competitive advantage), and subcontractor costs get 10–15% as a management and coordination fee. Change orders are where margin is often recovered — the industry standard markup on change orders is 15–20%, and owners expect it because changes mid-project carry disruption costs beyond the raw materials and labor involved. The critical distinction between markup and margin matters especially in construction bidding. If your materials cost $100,000 and you apply a 20% markup, your bid shows $120,000. But your margin on that line item is only 16.7% ($20,000 / $120,000). Many contractors lose money by confusing the two — bidding with what they think is a 20% margin when they have actually applied a 20% markup, leaving 3.3% of expected profit on the table on every job. This calculator converts between markup and margin instantly and is loaded with construction-specific benchmarks so you can build accurate bids.
