How do you calculate quote margin?

Subtract the required amount from the available amount to get the gap, then divide by the reference amount. With 125 available, 100 required, and 100 reference, the gap is 25 and the margin is 25 / 100 = 25%.

What is a good quote margin on mining equipment?

It depends on risk, but fabricators bidding heavy underground equipment often target 20-30% on the reference base to absorb steel swings and rework. The 25% in the worked example sits comfortably in that band.

What does the quote margin amount gap represent?

It is the raw dollar cushion between what you can charge and what you must cover — 25 in the example. The percentage just normalizes that cushion against the reference so different bid sizes compare fairly.

Available vs required amount — what is the difference?

Available is the price or margin you can realistically command in the market; required is the floor you must hit to cover cost and target return. The spread between them, divided by the reference, is your quote margin.

Can quote margin be negative?

Yes — if required exceeds available, the gap goes negative and so does the margin, signaling the quote is below its cost floor and should be repriced or walked away from.

Why use a reference amount instead of just the gap?

The reference normalizes the gap into a percentage so a 25-dollar cushion on a small bracket and a large casting are not judged on the same absolute scale. Here reference equals required, giving a clean 25%.

Mining Vehicle & Underground Equipment calculator

Quote Margin Calculator

Quote margin tells a mining-equipment fabricator how much headroom sits between the price they can command and the cost they must cover on a job — say building a continuous-miner cutter head or a fleet of haul-truck dump beds. Estimators and commercial managers use it during bid review to confirm a quote actually clears its cost floor before it goes to the customer. It matters because underground equipment work carries volatile steel, long machining hours, and stiff penalty clauses, so a thin or negative margin can quietly turn a flagship contract into a loss. Expressed as a percentage, it makes bids of very different sizes directly comparable.

What this calculator does

Estimate quote margin for mining vehicle and underground equipment using production-ready inputs so teams can measure the gap between available and required amounts.
Use it when quote margin in mining vehicle and underground equipment needs a clean margin number for a mining vehicle and underground equipment go / no-go review.
It computes the gap between the available and required margin amounts, then expresses that gap as a percentage of a reference amount to give a single quote-margin figure.

Formula used

Quote margin amount gap = available quote margin amount - required quote margin amount
Quote margin = amount gap ÷ reference quote margin amount

Inputs explained

Available quote margin amount:
Required quote margin amount:
Reference quote margin amount:

How to use the result

Use it at bid review to confirm a mining-equipment quote clears its cost floor and to compare margin across jobs of different sizes.
It is a static snapshot — it does not account for cost escalation, change orders, or penalty clauses that can erode the gap after award.

Current U.S. benchmarks

U.S. light vehicles sell at a 16.9 million annual rate (BEA, Jun 2026), up 4.1% from a year earlier, the volume signal for automotive supply chains.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).
