Frequently asked questions
Markup vs margin?▾
Markup = profit ÷ cost; margin = profit ÷ price. A 50% markup is a 33% margin — they're not the same.
Why is margin capped at 99.99%?▾
Margin = (price − cost) / price approaches 100% only when cost → 0; a 100% margin is impossible at any positive cost.
Does it include sales tax?▾
No — these are pre-tax pricing calculations. Add sales tax after.
