What is the difference between margin and markup?

Margin divides gross profit by selling price; markup divides gross profit by cost. A target entered here is the percentage of revenue retained after fabrication cost.

Why divide cost by one minus target margin?

That fraction is the share of revenue available to cover cost. Dividing cost by it finds the selling price that leaves your target share as gross profit.

Can the calculated margin be negative?

Yes. When estimated cost exceeds selling price, gross profit and gross margin are negative. Review the cost scope and price before releasing the quote.

Does meeting the target guarantee a profitable job?

No. Actual production expense can exceed the estimate, and gross profit must still fund excluded business expenses. Use the target as a quote policy check.

Fabrication Quote Margin Calculator

Check whether a fabrication quote meets your gross-margin policy. You need its estimated fabrication cost, selling price after discounts and target margin measured against revenue.

What this calculator does

Check quoted fabrication gross margin and the selling price needed to meet your entered target.

Formula used

Gross profit = quoted selling price − estimated fabrication cost
Gross margin (%) = gross profit ÷ quoted selling price × 100
Margin shortfall = target gross margin − calculated gross margin
Target selling price = estimated cost ÷ (1 − target gross margin ÷ 100)

Inputs explained

Estimated Fabrication Cost: Cost sheet materials, loaded labor, consumables and outside processing.
Quoted Selling Price: Customer quote revenue after discounts, excluding sales tax.
Target Gross Margin: Shop policy gross profit as a percentage of quote revenue.

How to use the result

Best suited to checking a fabrication quote before release, negotiating discounts against a margin policy.
Excludes selling and administration unless included in your entered cost. An estimate cannot guarantee the margin achieved after production.

Current U.S. benchmarks

The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
U.S. iron and steel import customs value ran $2.2B in Aug 2026 (Census International Trade). The U.S. ran a trade deficit of $0.6B in the category that month. This dollar total mixes price, quantity, product mix, origin, and timing; it does not measure physical import volume or prove a tariff or reshoring effect.
The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
