Roofing Material Markup Calculator
Price roofing material so delivery, handling, waste and warranty exposure are recovered.
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.

- Delivery and rooftop loading, which are real costs on a bulky material.
- Waste, which the customer does not see and which you buy.
- Warranty exposure, since material and workmanship warranties interact.
Where this one goes wrong
Marking up at the same rate across materials. A premium membrane and a bundle of shingles carry very different absolute numbers at the same percentage, and one of them will be questioned.
Questions
About this calculator
Should waste be in the markup or the quantity?
In the quantity, so it is visible and calculable. Hiding it in the markup means you cannot tell whether your waste allowance is right.
Is rooftop delivery worth charging separately?
It is a real cost and worth recovering somewhere. Buried in the markup it disappears; shown as a line it is easily explained.
How does the manufacturer warranty affect pricing?
Enhanced warranties often require certified installation and specific accessory products, which cost more. If you are selling that warranty, those requirements belong in the price.
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 $6,400.
- 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 | $6,400 |
| Markup on cost | 45% |
What comes out
| Result | Value |
|---|---|
| Price main result | $9,280 |
| Gross profit | $2,880 |
| Margin that gives you | 31.0% |
A 45% markup on $6,400 prices the job at $9,280, which is 31.0% margin, not 45%.
How sensitive the answer is
Holding everything else steady and changing only your cost, this is what happens to price. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Your cost ($) | Price |
|---|---|
| $3,200 | $4,640 |
| $4,800 | $6,960 |
| $6,400 example above | $9,280 |
| $9,600 | $13,920 |
| $12,800 | $18,560 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
What each figure means
- Your cost ($)
- A money amount, starting at $6,400.
- 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. |
What this cannot see
Material quantities assume a clean rectangular plane and the waste factor you enter. Valleys, hips, dormers, penetrations and a steep pitch all raise real waste, and a tear-off frequently uncovers decking that was not in the quote.
Estimating is the easy part
The jobs you never hear about cost more than the ones you mis-measure. BDEVY builds the marketing, systems and automation that bring them in.
