How do you calculate quote margin percentage?

Subtract the required cost and margin floor from quoted revenue to get margin dollars, then divide by the quote revenue reference and multiply by 100. With $148,000 quoted and a $126,500 floor, that's $21,500, or 14.53%.

What is a good quote margin on equipment attachments?

It varies by product and competition, but many attachment fabricators target 15% to 30% gross on a quote. The example 14.53% sits at the low end, leaving little room before the floor is breached.

What's the difference between margin and markup?

Margin is profit as a percent of revenue; markup is profit as a percent of cost. The $21,500 here is 14.53% of the $148,000 quote (margin) but about 17% of the $126,500 floor (markup).

How much can I discount before losing money on this quote?

Only down to the floor. The $21,500 margin dollars is your entire negotiating room — discount more than that and the quote falls below the cost-and-margin floor and you start eroding required profit or cost recovery.

Should freight and warranty be in the cost floor?

Yes. The floor should capture every committed cost — material, labor, outside processing, freight, warranty reserve, and the minimum profit you require. Leaving any out makes the 14.53% look safer than reality.

Why use a separate revenue reference?

The reference is the denominator for the percentage. Normally it equals quoted revenue so margin reads as a share of the quote, but you can change it to benchmark against a target or list price instead.

Construction Machinery & Attachments calculator

Quote Margin Calculator

Quote Margin shows how much profit a construction attachment or equipment bid carries above its true cost-and-margin floor, in both dollars and percent. Estimators and sales engineers use it the moment a customer pushes back on price — it reveals exactly how much room there is to negotiate before a quote drops below the floor that covers fully loaded cost plus the minimum acceptable profit. For attachment work where steel prices, hydraulic components, and outside machining swing hard, knowing the margin on every quote keeps the shop from winning unprofitable jobs. It converts a quoted number and a cost floor into a clean percentage you can compare across deals.

What this calculator does

Calculate margin on construction machinery or attachment quotes.
checking quote profitability before releasing a dealer, rental, or customer price
It computes quote margin dollars as quoted revenue minus the required cost and margin floor, then expresses that as a percentage of the quote revenue reference.

Formula used

Quote margin dollars = quoted attachment or equipment revenue - required cost and margin floor
Quote margin = quote margin dollars ÷ quote revenue reference × 100

Inputs explained

Quoted attachment or equipment revenue:
Required cost and margin floor:
Quote revenue reference for percentage basis:

How to use the result

Use it when finalizing a bid, evaluating a customer's counteroffer, or ranking which open quotes are worth chasing.
The result is only as honest as the cost-and-margin floor you enter; if that floor omits real costs like warranty, freight, or financing, the margin will look better than it is.
