Are You Losing Money on Every Quote? The Margin vs. Markup Mistake That's Costing Your Shop Thousands
If you're running a powder coating shop and you think you're making 15% profit on your jobs, there's a good chance you're actually making closer to 13%. Over a year, that 2% gap could mean tens of thousands of dollars walking out the door.
Here's the problem: most shop owners confuse margin and markup — and they don't even know it.
The $100 Job
Let's say a job costs you $100 to complete. Materials, labor, overhead — all in, $100. You want to make 15% profit. Simple, right?
Here's where it gets tricky.
What most shops do (markup): They take $100 and multiply by 1.15. That gives them $115. They quote $115 and think they're making 15%.
But they're not. That $15 profit is only 13% of the $115 selling price. The customer paid $115, and only $15 of that is profit. That's 13%, not 15%.
What they should do (true margin): Take $100 and divide by 0.85. That gives $117.65. Now the profit is $17.65 — which is exactly 15% of $117.65.
The difference on one job is small. But multiply it across hundreds or thousands of jobs per year, and you're leaving real money on the table.
It Gets Worse at Higher Margins
The gap between markup and true margin gets bigger as your target percentage goes up.
Say you want 30% profit:
Markup: $100 × 1.30 = $130. Your $30 profit is actually only 23% of the $130 selling price.
True margin: $100 / 0.70 = $142.86. Your $42.86 profit is a real 30% of the selling price.
That's a $12.86 difference per job. If you're doing 20 jobs a day at an average cost of $500, the markup method is costing you over $1,200 a week — more than $60,000 a year.
Why Does This Happen?
Because markup is easier to calculate in your head. "Add 15%" is simple math. Dividing by 0.85 isn't something most people do on the fly.
And honestly, a lot of quoting software gets this wrong too. Some tools just multiply the cost by (1 + margin percentage), which is the markup formula — not the margin formula.
The Formulas
Markup (what you don't want): Selling Price = Cost × (1 + Percentage)
True Margin (what you do want): Selling Price = Cost ÷ (1 - Percentage)
When you say "I want 15% margin," you're saying "15% of my selling price should be profit." The only formula that delivers that is the division formula.
A Quick Reference
Here's what you're actually making if you use the markup method instead of the true margin method:
| What You Set | What Markup Gives You | What True Margin Gives You | Money Left on the Table |
|---|---|---|---|
| 10% | 9.1% actual margin | 10% actual margin | $0.99 per $100 job |
| 15% | 13.0% actual margin | 15% actual margin | $2.65 per $100 job |
| 20% | 16.7% actual margin | 20% actual margin | $5.00 per $100 job |
| 25% | 20.0% actual margin | 25% actual margin | $8.33 per $100 job |
| 30% | 23.1% actual margin | 30% actual margin | $12.86 per $100 job |
| 40% | 28.6% actual margin | 40% actual margin | $26.19 per $100 job |
What Should You Do?
First, check your quoting tool or spreadsheet. Look at how it calculates the final price. If it multiplies your cost by (1 + margin), it's using the markup formula and you're not getting the margin you think you are.
Second, if you're quoting by hand or using a calculator, train yourself to divide instead of multiply. Want 20% margin? Divide your cost by 0.80. Want 25%? Divide by 0.75. It becomes second nature after a few days.
Third — and this is the easy one — Quote Genius Pro uses the true margin formula in every quote it generates. When you set 15% margin, you get 15% margin. Not 13%. Not "close enough." The actual number.
It's one of those details that doesn't sound like a big deal until you do the math across a full year of jobs. Then it sounds like a new oven.
