Markup Calculator

Find markup percentage as (selling price − cost)/cost × 100. Provide Unit cost, Selling price to compute results directly in your browser. Positive unit cost required; all amounts use one currency. A price below cost returns negative markup, distinct from profit margin on revenue. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.

How to Read and Verify the Markup Calculator Output

The output panel reports the exact result derived from Unit cost, Selling price alongside any unit or formatting notes.

The result is the markup percentage. Express the price increase or decrease relative to the supplied cost.

Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.

Markup divides the price increase by cost. Profit Margin Calculator divides profit by revenue.
