How do you calculate quote margin?

Subtract cost from price for dollar margin, then divide by the reference base for percent. Here $125 price minus $100 cost is $25 margin, and against a $100 base that's a 25% margin.

What is a good margin on a trailer quote?

Custom trailer and truck-body work typically targets 20-35% gross margin, with standard catalog units running thinner. Below 15% leaves no cushion for change orders or material swings and should be quoted only strategically.

Is this margin or markup?

It depends on the reference base. Dividing the $25 by the $100 cost gives 25% markup on cost; dividing by a $125 selling price would give 20% margin on price. Choose the base that matches your quoting convention.

Margin vs markup — what's the difference on a quote?

Markup is profit as a percent of cost; margin is profit as a percent of selling price. A 25% markup on a $100 cost is only a 20% margin on the resulting $125 price — a common source of underpricing.

How do I use this to set a target price?

Work backward: take your fully-loaded cost, pick your target margin, and solve for price. If cost is $100 and you want 25% markup on cost, quote $125 as in this example.

Why does the reference base matter so much?

Because the same $25 of profit is 25% of a $100 cost but 20% of a $125 price. Reporting margin against the wrong base overstates profitability and erodes real dollars over a year of quotes.

Trailers, Truck Bodies & Specialty Vehicles calculator

Quote Margin Calculator

Quote margin is the profit left on a trailer or specialty-vehicle quote after fully-loaded build cost, expressed both as dollars and as a percentage of the reference base. Estimators and sales engineers use it to check every quote before it goes out the door, because on a custom truck-body job a thin margin can vanish entirely to a single change order or a steel price move. It's the fastest way to see whether a quote is worth winning — or whether you're about to buy the business at a loss.

What this calculator does

Quote margin is the profit left on a trailer or specialty-vehicle quote after fully-loaded build cost, expressed both as dollars and as a percentage of the reference base.
Use it when quote margin in trailers, truck bodies and specialty vehicles needs a clean margin number for a trailers, truck bodies and specialty vehicles go / no-go review.
It subtracts required cost from available price to get dollar margin, then divides by the reference base to express that margin as a percent.

Formula used

Quote Margin margin = available value - required value
Margin percent = margin ÷ reference value

Inputs explained

Quoted selling price:
Fully-loaded build cost:
Margin reference base (usually selling price):

How to use the result

Use it on every quote before submission, when steel or component costs shift, or when deciding how much room you have to negotiate on a competitive bid.
It uses whatever reference base you enter — dividing margin by price gives markup on price, while dividing by cost gives markup on cost. Mixing the two makes quotes look more or less profitable than they are, so pick one convention and hold it.
