66.6667 is the example result. The cost base is the denominator. A 50% markup corresponds to a one-third selling-price margin when there are no other costs.
Measure the increase from cost to selling price. This is useful when your quoting process starts with a cost base and applies an uplift.
Distinguish markup from margin
Markup divides the price less cost by cost. If cost is 80 and price is 100, markup is 25%, while selling margin is 20%. Both figures describe the same transaction through different denominators.
When to use this result
Use markup when you need to check a supplier uplift or compare how a cost-based quote was assembled. Use margin when the question concerns the share of sales retained.
Check before you act
A cost of zero makes percentage markup undefined. Include the delivery costs your pricing policy is meant to recover.
Example with the supplied inputs
Cost: 60; Selling price: 100. Result: 66.6667. The values are illustrative.
Compare one changed input
Cost changes from 60 to 66. The result becomes 51.5152. All other inputs remain fixed.
Calculation rule
Result = (([Selling price] − [Cost]) ÷ ([Cost])) × 100
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Cost | 60 | Use cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
| Selling price | 100 | Use selling price on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
Output: 66.6667 is the example result. The cost base is the denominator. A 50% markup corresponds to a one-third selling-price margin when there are no other costs. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Cost, Selling price. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Cost on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 66.6667.
Change Cost from 60 to 66 while keeping every other value fixed. The result becomes 51.5152. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
