What the calculation measures
A 50% markup does not equal a 50% margin. This tool shows both so you can communicate pricing targets correctly.
How to interpret the result
Use the resulting selling price as a starting point, then account for overhead, channel fees and desired market positioning.
Run scenarios instead of one answer
Change the most uncertain input and compare outcomes. A calculator is most useful when it shows sensitivity, not when one estimate is treated as a guarantee.
Limits and assumptions
Taxes and transaction-specific fees are not automatically added.
