Chimney Markup Calculator
Works markup on chimney work, where materials are a small share and labour is most of it.
Result
Markup is measured against your cost, margin against the price you charge. A 50% markup is a 33.3% margin, not a 50% one. Pricing off the wrong one is the most common way a job that looked profitable turns out not to have been.

Markup is applied to cost and produces a price with a corresponding margin that is always lower than the markup percentage. Both are shown. In chimney work the balance is unusual: materials on a sweep or an inspection are negligible, and even on masonry repair the brick, mortar and liner are modest against the labour and access. That means marking up materials achieves very little, and the price has to come from a properly burdened labour rate rather than from a markup on parts.
What moves the number
- The ratio of labour to materials, which is heavily labour weighted.
- Whether the labour rate is genuinely burdened, since markup cannot rescue it.
- Equipment and access costs, which behave like labour rather than materials.
- Subcontracted work such as roofing, where markup does apply.
Where this one goes wrong
Marking up materials is not a pricing strategy in a labour-dominated trade. A sweep with twenty dollars of materials cannot be priced by marking those up, and a business that thinks of its margin as a markup on parts has no mechanism for making money on its main service. The rate has to carry the burden, the overhead, the access cost and the profit. Where markup does matter is on subcontracted work and on the occasional large material item such as a liner or a prefabricated chimney system, and there the margin and markup distinction needs the same care as anywhere else.
Before you quote
- Price from a burdened labour rate rather than a markup on materials.
- Apply markup to subcontracted work and large material items.
- Check the resulting margin against the markup applied.
Questions
About this calculator
Can I price chimney work by marking up materials?
No, because materials are a small share. A sweep uses almost none, and even masonry repair is labour and access dominated. The price has to come from a properly burdened labour rate that carries overhead, equipment and profit. Markup on parts has nothing to work with.
Where does markup apply in this trade?
On subcontracted work such as roofing, and on the occasional substantial material item like a liner or a prefabricated chimney system. On those, the usual care applies: a markup percentage is not the same as the margin it produces, which is why both figures are shown.
Is a 50% markup a 50% margin?
No, it is a 33.3% margin, because markup is measured against cost and margin against price. Confusing them is the most expensive arithmetic error in contracting, and a business targeting a margin by applying it as a markup falls short on every job.
The formula
price = cost x (1 + markup%); margin = profit / price

How to use this calculator
- Your cost ($). Enter your own figure; the page starts at $210.
- Markup on cost (%). Enter your own figure; the page starts at 45%.
The result updates as you type, so you can try a figure, see what it does to price, and change it back. Nothing you enter is sent anywhere or saved.
A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Your cost | $210 |
| Markup on cost | 45% |
What comes out
| Result | Value |
|---|---|
| Price main result | $304.50 |
| Gross profit | $94.50 |
| Margin that gives you | 31.0% |
A 45% markup on $210 prices the job at $304.50, which is 31.0% margin, not 45%.
How sensitive the answer is
Holding everything else steady and changing only your cost, this is what happens to price. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Your cost ($) | Price |
|---|---|
| $105 | $152.25 |
| $158 | $229.10 |
| $210 example above | $304.50 |
| $315 | $456.75 |
| $420 | $609 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
What each figure means
- Your cost ($)
- A money amount, starting at $210.
- Markup on cost (%)
- A percentage, between 0 and 500, starting at 45%.
What the results tell you
| Result | What it is |
|---|---|
| Price | The headline result. A money figure. |
| Gross profit | A money figure. |
| Margin that gives you | A percentage. |
