Markup & margin calculator

Worksheet

Your costs and your price — with the markup and the margin both worked out, from the same two figures.

Quote one, get the other

A contractor who prices at “forty percent” meaning margin and applies it as markup is short on every job for a year, and the shortfall is invisible until the year is over. The two numbers come from one cost and one price, so there is no reason to make somebody choose between them: both appear, labeled, on the same sheet.

Nothing here suggests a number

There is no default markup, no placeholder percentage and no “industry average” anywhere on the page. Every figure is one you typed. That is deliberate: a number this product invented would be priced into somebody’s work, and neither of us would ever know.

Whole cents, all the way through

Costs are added in integer cents and the percentages are held as whole basis points, so the sheet foots against its own visible column. Nothing floats and nothing drifts by a cent between the line and the total.

A worksheet that does arithmetic on figures you entered. CompliMaint suggests no markup or margin, publishes no benchmark, applies no tax and gives no pricing, financial or tax advice. Everything runs on your device.

Questions people ask

What is the difference between markup and margin?
They share a numerator and have different denominators. Markup is the gross divided by your COST; margin is the same gross divided by your PRICE. A $100 cost sold at $150 is a 50% markup and a 33.33% margin. That is why this tool shows both and labels which is which, rather than asking you to pick a word.
What markup should I use?
This tool does not say, and it never will. It publishes no suggested markup, no typical margin and no industry benchmark, because what you should charge depends on your market, your overhead, your risk on the job and what you are prepared to walk away from. Those are business decisions, not arithmetic.
Does it add sales tax?
No. It applies no tax of any kind and holds no tax rate. What tax applies to your work, and whether it goes on top of the price or comes out of it, depends on where you are and what you are selling — put the price you are actually quoting into the box.
Why is the margin blank sometimes?
Because a percentage of nothing is not zero percent — it is not a percentage. If your price is zero there is no margin to take, and if your cost is zero there is no cost to mark up. The tool says so rather than printing a misleading 0%.
Where does the arithmetic happen?
In one tested module shared by every calculator in this batch, in whole cents throughout. Nothing is computed inside the page, and no figure is rounded twice.
