Markup is the percentage you add on top of your cost to get a sale price. If a material costs you $100 and you mark it up 50%, you sell it for $150.
Margin is the percentage of the sale price that's profit. On that same $150 sale of a $100 cost item, your $50 profit is 33.3% of the sale price — a 33.3% margin.
Same transaction, two different numbers. Contractors who quote a "50% margin" when they mean "50% markup" are under-charging on every line of every estimate.
