How do you calculate quote margin?

Subtract job cost from the quoted price to get dollar margin, then divide by your reference revenue. A $125 quote against $100 cost yields $25 of margin, which is a 25% margin on the $100 reference.

What is the difference between margin and markup?

Margin divides profit by revenue; markup divides profit by cost. The same $25 on a $100 cost is a 25% margin if referenced to revenue but a 25% markup only when the reference and cost match — always confirm which base you entered.

What is a good margin on a sign quote?

Fabrication-heavy signage often targets 40-55% gross margin to cover shop overhead, while install-heavy or reseller jobs run thinner. A 25% margin like the example is lean and leaves little cushion for change orders.

Why does the reference amount matter?

It sets the denominator for the percentage. Entering quoted price as the reference gives true margin; entering cost gives markup. The dollar margin stays $25 either way, but the percent shifts.

Can quote margin be negative?

Yes — if job cost exceeds the quoted price, margin goes negative and you are quoting a loss. That is exactly the signal to catch before the quote leaves your desk.

How do I improve margin without raising the price?

Cut job cost: reduce material waste, improve labor capture, or renegotiate substrate pricing. Trimming $10 of cost on this job would lift margin from $25 to $35 with no change to the client-facing number.

Signage, Displays & Architectural Graphics calculator

Quote Margin Calculator

Quote Margin shows how much of a signage quote survives after job cost — expressed both in dollars and as a percentage of the reference revenue. Sign estimators live and die by this number because signage jobs stack materials, labor, install, and permit costs that erode a healthy-looking price fast. Owners and salespeople use it to sanity-check a quote before it goes out and to compare profitability across dissimilar jobs. A quote that looks big can carry a thin margin, and this calculator surfaces that in one line.

What this calculator does

Quote Margin shows how much of a signage quote survives after job cost — expressed both in dollars and as a percentage of the reference revenue.
Use it when quote margin in signage, displays and architectural graphics needs a clean margin number for a signage, displays and architectural graphics go / no-go review.
It computes the dollar margin between quoted price and job cost, then expresses that margin as a percent of a reference revenue base.

Formula used

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

Inputs explained

Quoted price to client:
Fully-loaded job cost:
Revenue base for margin:

How to use the result

Use it right before sending a quote, or when reviewing won jobs to see which sign types actually pay.
Margin percent depends on which reference base you enter — mixing revenue and cost as the base produces markup, not margin, so be deliberate.
