Markup vs. Margin: The Difference That Costs Contractors Thousands
This is the most expensive math mistake in the trades. Contractors confuse markup and margin every day. They say "I want a 50% margin" but they calculate a 50% markup. The result? They make 33% instead of 50%. On a million dollars in revenue, that's $170,000 in lost profit.
It's not a rounding error. It's a business-killing mistake. And it happens because the two numbers sound like they should mean the same thing. They don't.
What's the Difference?
Markup is how much you add on top of your cost. It's based on your cost.
Margin is how much of the final price is profit. It's based on the sell price.
Same profit number. Different denominator. Completely different percentage.
The $500 Job Example
Your costs on a job are $500. You want "50%." Here's what actually happens:
If you apply a 50% markup: $500 × 1.50 = $750 sell price. Your profit is $250. Your actual margin is $250 ÷ $750 = 33.3%. Not 50%.
If you want a 50% margin: $500 ÷ (1 - 0.50) = $1,000 sell price. Your profit is $500. That's a real 50% margin.
The difference? $250 per job. If you run 40 jobs a month, that's $10,000/month. $120,000 a year. Gone. Because of one word.
Why Margin Matters More Than Markup
Markup is useful for quick math in the field. "Add 50% to my costs." Easy to calculate on the fly.
But margin is what your business actually runs on. When your accountant talks about your profit margin, when a PE firm values your business, when your bank looks at your financials... they're all looking at margin, not markup.
If you price using markup but your financial targets are in margin, you'll always come up short. You'll wonder why the books don't match the bids.

Common Markup/Margin Pairs Every Contractor Should Know
20% markup = 16.7% margin. This is bare minimum territory. You're covering costs and that's about it. One bad callback wipes out your profit on two jobs.
50% markup = 33.3% margin. This is where most successful contractors land. Healthy but not excessive. Enough cushion for the inevitable surprises.
100% markup = 50% margin. Common in emergency/after-hours work. You're charging double your cost. Sounds aggressive until you factor in the overhead of being available 24/7.
Which One Should I Use for Pricing?
Set your targets in margin. Calculate your prices using markup.
Here's why. Your financial targets (20% net margin, 30% gross margin) are always expressed in margin. Your CPA, your business coach, your industry benchmarks... all margin.
But in the field, markup is easier to calculate. If you know your cost is $400 and you need a 43% markup to hit your 30% margin target, that's $400 × 1.43 = $572. Done.
The key is knowing the conversion. A 30% margin requires a 43% markup. Not a 30% markup. Write this on the wall of your shop.

Frequently Asked Questions
What is the difference between markup and margin?
Markup is the percentage added on top of your cost. Margin is the percentage of the final selling price that is profit. They use different denominators: markup is calculated from cost, margin is calculated from revenue. A 50% markup on $500 means you charge $750 and keep $250, giving you a 33.3% margin. The same number produces very different results depending on which one you use.
How do you convert markup to margin?
Use the formula: Margin = Markup divided by (1 + Markup). For example, a 50% markup (0.50) converts to: 0.50 divided by 1.50 = 0.333, or 33.3% margin. Going the other direction, Markup = Margin divided by (1 minus Margin). A 30% margin requires a 42.9% markup. This calculator does both conversions instantly.
What markup percentage should contractors use?
Most successful contractors target 35-50% markup on residential work, which translates to 26-33% margins. HVAC parts markup typically runs 25-100% depending on the component. Plumbing flat rate books commonly use 50-65% markup. The right number depends on your overhead, your market, and your margin targets. Set your goals in margin, then calculate the markup needed to hit them.
Why do contractors lose money confusing markup with margin?
When a contractor says they want a "30% profit" and applies a 30% markup, they actually earn a 23% margin. On a $100,000 in annual revenue, that confusion costs roughly $7,000 in missed profit. Multiply across hundreds of jobs per year and the gap becomes tens of thousands of dollars. The fix is simple: know which number you are using and calculate accordingly.
Is it better to price using markup or margin?
Set your financial targets in margin and calculate your prices using markup. Your accountant, your bank, and any potential buyer of your business all evaluate you on margin. But in the field, markup is easier to apply: if your cost is $400 and you need a 43% markup to hit 30% margin, you just multiply $400 by 1.43 to get $572. Know the conversion between the two and you will price correctly every time.
What is a good profit margin for contractors?
Healthy trade businesses target 20-30% net margin. Service calls in HVAC and plumbing can hit 45-55%. Roofing and general contracting typically run 25-35% gross margin. If your margin is consistently below 15%, you are likely underpricing, overspending on overhead, or both. Top performers in the trades hit 30%+ by tracking every job and adjusting prices based on real cost data.
