Pump, Compressor & Rotating Equipment Assembly calculator

Quote Margin Calculator

Quote Margin is the difference between what you quote a customer for an assembled pump or compressor and your fully loaded cost to build it, expressed both in dollars and as a percentage of a chosen basis. Estimators and sales engineers on rotating-equipment programs use it to make sure a bid covers the real cost of seals, bearings, balancing, run-in testing, and warranty exposure — not just the bill of materials. It matters because rotating equipment carries hidden cost of quality: a thin quote margin gets wiped out the first time a unit comes back for a seal or balance failure, so the margin has to carry that risk.

What this calculator does

  • Quote Margin is the difference between what you quote a customer for an assembled pump or compressor and your fully loaded cost to build it, expressed both in dollars and as a percentage of a chosen basis.
  • Use it when quote margin in pump, compressor and rotating equipment assembly needs a clean margin number for a pump, compressor and rotating equipment assembly go / no-go review.
  • It computes the margin between quoted price and loaded cost, both as an absolute dollar figure and as a percentage of a reference basis.

Formula used

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

Inputs explained

  • Quoted price per assembled unit:
  • Fully loaded cost per assembled unit:
  • Reference basis for margin percent:

How to use the result

  • Use it while pricing a bid, comparing two quote structures, or checking whether a program still clears margin after warranty and field failure cost are loaded in.
  • The percent depends entirely on the reference basis you choose — dividing by cost gives markup, dividing by price gives true margin — so label which one you mean.

Current U.S. benchmarks

  • Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
  • Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
  • 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 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).

Common questions

  • How do you calculate quote margin? Subtract fully loaded cost from quoted price, then divide by your reference basis. With a $125 quote and $100 cost, the dollar margin is $25 and dividing by the 100 reference gives 25%.
  • Is 25% a good quote margin for rotating equipment? For assembled pumps and compressors, 25-40% gross margin is common because warranty and field failure risk is real. The 25% in the example is on the lean side once you load in seal and balance warranty exposure.
  • What's the difference between margin on cost and margin on price? Dividing the $25 by the $100 cost gives a 25% markup; dividing by a $125 price gives a 20% true margin. The calculator uses the reference you supply, so decide which one your finance team reports.
  • What should be in the fully loaded cost? Everything to ship a good unit — bill of materials, direct assembly labor, balancing and test time, consumables, and an allowance for warranty and field failure cost. Quoting off BOM alone is how programs go underwater.
  • Why is my quote margin thinner than expected on delivery? Usually because field failure cost and rework were not loaded into the cost side at quote time. If per-unit field failure cost runs $38 on a $25 margin, the program is losing money on every return.
