Protect margins from rising costs

Stop double-counting
A 25% markup is not a 25% margin. Know the real margin before you commit.
Pricing discipline
Tie menu and shelf prices to cost with a consistent rule.
Prepares for thin-margin checks
Once you know margin percent, you can flag lines that are too tight.

What is the difference between markup and margin?

Markup is on cost; margin is on selling price. The same markup percent yields a lower margin percent.

Which should I use for pricing?

Many operators think in markup but should track margin. This tool bridges both.

What happens when cost rises?

Fixed markup percent gives you a higher dollar margin but a lower margin percent — rerun after each cost change.
