Industrial Fans, Blowers & Air Movement Equipment calculator

Quote Margin Calculator

Quote Margin tells an estimator whether a fan or blower quote clears the margin the business needs before it goes out the door. Sales engineers and estimators in air-movement OEMs use it to sanity-check a bid: does the dollar margin baked into this configuration beat the floor target, and by how much of the order's revenue? It matters because custom fan quotes carry swingy material and motor costs, and a quote that looks profitable in dollars can still be thin against a large revenue base. The calculator returns the margin gap in dollars and as a percent of quote revenue, so cushion is visible relative to deal size.

What this calculator does

  • Calculate quote margin gap by comparing available quoted margin with required margin and project revenue basis.
  • Use it when reviewing quotes for industrial fans, blowers, dust collection fans, custom housings, motors, drives, or test requirements.
  • It subtracts the required margin target from the available quoted margin, then divides that gap by quote revenue to show cushion as a percent.

Formula used

  • Quote margin gap = available quoted margin - required margin target
  • Quote margin gap percent = quote margin gap ÷ quote revenue basis

Inputs explained

  • Margin available in the fan quote:
  • Minimum margin the quote must clear:
  • Total quoted fan order revenue:

How to use the result

  • Use it during quote review or bid approval to confirm a fan order beats the margin floor before sending it to the customer.
  • It's a dollar comparison against a target you supply — it doesn't model cost risk, escalation or warranty reserve, so a thin positive gap can still go negative if material costs move.

Current U.S. benchmarks

  • 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).

Common questions

  • How do you calculate a quote margin gap? Subtract the required margin target from the available quoted margin. With $42,000 available against a $36,000 target, the gap is $6,000 of cushion above the floor.
  • What does the margin gap percent mean? It's the dollar gap divided by quote revenue. Here $6,000 over $180,000 of revenue is 3.33% — the quote clears its margin floor by just over three points of revenue.
  • What is a good quote margin gap? Any positive gap clears your floor, but the percent matters: 3.33% of revenue is a modest cushion. On volatile fan builds you may want more headroom to absorb material swings.
  • Quote margin gap vs gross margin percent? Gross margin percent is margin over revenue outright; this gap measures margin above your required target, so it answers 'how much room do I have before I breach the floor' rather than the absolute margin level.
  • What if the gap is negative? A negative gap means the quote falls below your margin floor — you'd need to raise price, re-scope the fan configuration, or cut cost before approving the bid.
