## FAQs
Q: What's the difference between margin and markup?
A: Margin is profit divided by price. Markup is profit divided by cost. A 30% margin requires roughly a 43% markup.

Q: What margin should contractors target?
A: It varies by trade and market. Many contractors target 25–40% gross margin so overhead and net profit are both covered — check your own overhead rate before setting a number.
