Construction Material Markup Calculator

Markup is added to cost. Margin is measured out of the selling price. The same dollar of profit produces two different percentages depending on which base you divide by.

• Customer price = material cost × (1 + markup ÷ 100)
• Gross profit = customer price − material cost
• Gross margin % = gross profit ÷ customer price × 100
• To hit a target margin instead: price = cost ÷ (1 − target margin ÷ 100)

The customer price is your material cost with markup added. The gross margin shown is what that price actually yields — always a smaller percentage than the markup you applied.

Common mistakes and assumptions

• Applying your target margin as a markup, which underprices the job.
• Marking up material cost without a waste allowance in the cost figure.
• Reading gross profit as job profit; labor, equipment, and overhead are not included here.

A siding package costs $8,400 and the company marks materials up 22%.

1. 1Customer price = $8,400 × 1.22 = $10,248.
2. 2Gross profit = $10,248 − $8,400 = $1,848.
3. 3Gross margin = $1,848 ÷ $10,248 = 18.03% — noticeably less than the 22% markup.

What markup should I use on materials?

It depends on handling, risk, and warranty exposure rather than a universal rule. What matters is that the markup you choose covers procurement time, delivery, breakage, and the overhead your labor rate does not already carry.

How do I price for a specific margin?

Divide cost by (1 − margin as a decimal). For a 30% margin on $8,400 of material: $8,400 ÷ 0.70 = $12,000.

Should tax and freight be in the cost?

Yes — include everything you pay to get the material to the job. Marking up a cost that excludes freight understates your price and eats the difference out of profit.

Does this cover labor?

No. Materials and labor usually carry different markups. Use the Labor Burden Calculator to get your true hourly labor cost before you mark labor up.
