Markup vs Margin: The Pricing Mistake That Quietly Kills Builders
The Two Words That Cost Builders the Most Money
Ask a room of builders what margin they make and most will tell you a number. Ask them how they worked it out and a lot of them are actually describing markup, not margin. They think the two words mean the same thing. They do not, and that misunderstanding is quietly bleeding money out of their business on every job.
Here is why it matters. If you want to make twenty percent on a job and you add twenty percent to your costs, you do not make twenty percent. You make less. Do that on every quote for a year and the gap between what you thought you made and what you actually made is real money, gone.
This is not accounting theory. It is one of the most practical things a builder can get right, and it takes about five minutes to understand for good.
TL;DR
Markup is what you add to your cost. Margin is what you keep from the sale price
They are different numbers, and markup is always the bigger percentage
Adding 20 percent markup gives you a 16.7 percent margin, not 20 percent
To hit a target margin, divide your cost by (1 minus the margin), do not just add the percentage
Confusing the two means you are quietly underpricing every job
Why This Trips Up So Many Good Builders
There is no shame in getting this wrong, because the words genuinely sound interchangeable and nobody teaches it on site. You learn to price by watching whoever trained you, and if they added a percentage on top of costs and called it their margin, you inherited the mistake. Most builders are brilliant at the work and were simply never shown the difference. Five minutes fixes it permanently.
Builder and Business Owner
I thought I was running a twenty percent margin for years. Turned out I was adding twenty percent markup, which is really about sixteen. On my turnover that difference was tens of thousands of dollars a year I thought I was making and was not. Learning this properly is the best five minutes I ever spent.
The Difference, in Plain Terms
Both markup and margin describe the profit built into a job. The difference is what you measure that profit against.
Markup is measured against your cost. It is the amount you add on top of what the job costs you. If a job costs you $10,000 and you add 20 percent, that is $2,000 of markup, and you charge $12,000.
Margin is measured against your sale price. It is the share of the final price that is profit. On that same job, your $2,000 of profit divided by the $12,000 sale price is 16.7 percent. That is your margin.
Same job, same dollars of profit, two different percentages, because they are measured against two different things. Markup looks at your cost. Margin looks at your price. And because your price is always bigger than your cost, your margin percentage is always smaller than your markup percentage.
Why It Matters So Much
Because most builders set a target in their head as a margin ("I want to make 20 percent") but then price it as a markup (add 20 percent to cost). Those are not the same, so they systematically fall short of the number they were aiming for, on every job.
The bigger the markup, the bigger the gap. Look at how they diverge.
Markup to Margin Reference Table
Markup added to cost | Margin you actually get |
|---|---|
10% | 9.1% |
15% | 13.0% |
20% | 16.7% |
25% | 20.0% |
30% | 23.1% |
40% | 28.6% |
50% | 33.3% |
100% | 50.0% |
Read that table once and the lesson jumps out. To actually make a 20 percent margin, you need to add 25 percent markup, not 20. If you have been adding 20 and calling it your margin, you have been leaving real money on the table every time.
The Formula to Get It Right
You do not need to memorise the table. You need one formula.
To hit a target margin, take your cost and divide it by (1 minus your target margin, as a decimal).
Say a job costs you $10,000 and you want a 25 percent margin. That is 1 minus 0.25, which is 0.75. So $10,000 divided by 0.75 equals $13,333. Charge $13,333 and you make a true 25 percent margin.
Want 30 percent? Divide by 0.70. Want 20 percent? Divide by 0.80. That single calculation, done on every quote, guarantees you actually hit the margin you were aiming for instead of quietly missing it.
Which Should You Use?
Use markup as the tool and margin as the target. In practice, you decide the margin you need to run a healthy business, then use the formula to convert it into the price. The markup is just the mechanism that gets you there.
What you must never do is set a margin target and then apply that same number as a markup. That is the exact mistake this whole article is about, and it is the difference between the profit you planned for and the smaller one you actually get.
One More Thing: Know Your Real Costs First
None of this works if the cost you start with is wrong. Markup and margin are both calculated on your costs, so if you have left things out, the maths is perfect and the answer is still wrong. Make sure your cost includes everything: labour at its true rate, materials with wastage, subcontractors, and your overheads. Getting the pricing built up properly first is what makes the margin calculation meaningful.
The Bottom Line
Markup is what you add to cost. Margin is what you keep from the sale price. They are different numbers, markup is always the larger one, and confusing them means you underprice every job you ever quote. Set your target as a margin, use the formula to turn it into a price, and never again apply a margin figure as a markup. It is five minutes of maths that pays you back on every quote for the rest of your career.
