Fabrication Quote Margin Calculator
An Excel calculator that keeps cost, selling price, markup, gross margin, allowances, tax basis, and sensitivity visible for quote review.

What this resource is for
Markup and gross margin are related but different calculations. Confusing the two can produce a selling price that does not match the intended commercial result.
The calculator shows cost, selling price, markup, gross profit, gross margin, and selected sensitivity cases side by side. It does not determine the right price or predict net profit.
Designed for: Fabrication estimators and owners checking the commercial result of cost-based quotes.
What is included

Fields and review points
How to use it
Start from reviewed cost
Use the approved estimate basis, including the company’s treatment of direct cost, overhead, allowances, freight, outside services, and tax.
Choose the intended calculation
Use either markup on cost or target gross margin on selling price deliberately. Keep the selected method and resulting price visible.
Review sensitivity, not just one answer
Check how supplier movement, labour change, allowance, discount, or scope uncertainty affects gross profit and margin before approving the quote.
Important review boundaries
- Gross margin is not net profit or cash flow.
- The calculator does not recommend a price or guarantee profitability.
- Confirm tax, overhead, commission, warranty, risk, and business-specific cost treatment.
Questions about this resource
What is the markup formula?
Markup percentage is commonly calculated as gross profit divided by cost. Selling price from markup is cost multiplied by one plus the markup rate.
What is the gross margin formula?
Gross margin percentage is commonly calculated as gross profit divided by selling price. The workbook displays both bases so they are not used interchangeably.
