What Is a Construction Profit Margin Calculator?

The construction profit margin calculator finds profit, margin percentage, and markup percentage from revenue and cost. It shows the difference between margin, profit as a share of revenue, and markup, profit as a share of cost. Contractors use it to price work and to review how jobs actually performed.

How It Works

Profit = Revenue − Cost. Margin % = Profit ÷ Revenue × 100. Markup % = Profit ÷ Cost × 100.

Example

$100,000 revenue on $80,000 cost: $20,000 profit → 20% margin, 25% markup.

How to Calculate

  1. Enter the revenue you expect or billed for the project, such as $100,000.
  2. Enter the total cost of the project, such as $80,000.
  3. Read the profit, which is revenue minus cost. That gives $20,000.
  4. Read the margin percentage, which is profit divided by revenue. That gives 20%.
  5. Read the markup percentage, which is profit divided by cost. That gives 25%, and use it to check your pricing.

Frequently Asked Questions

Margin or markup — which do I quote?

Quotes are usually built on markup (cost × factor), but margin shows your true profit share of the sale price.

What is a healthy construction margin?

Net margins of 5–15% are typical for contractors, depending on the trade and market.

Why do the two percentages differ?

Because they use different bases — revenue for margin, cost for markup — so the same profit yields different numbers.

Mason Reid founded MeasureThen after two decades of hands-on work in construction and estimating. Across residential and light commercial projects, he sized concrete pours, framed walls, hung drywall, and priced out roofing, fencing, and deck work — learning the exact math that every job depends on. At MeasureThen he writes the formulas, checks every calculator against real-world assumptions, and makes sure each one is simple enough for a homeowner to trust and a contractor to use. When he is not measuring twice, he is helping projects stay on budget.

Every MeasureThen calculator uses simple, transparent formulas and standard industry assumptions drawn from common construction practice. We show the math behind each result and include worked examples so you can follow along and double-check the numbers. Results are estimates: materials, labor, and pricing vary by region and market, so always confirm important figures with a licensed professional and your local building codes.
