How do you calculate total labor cost for a fan build?

Multiply labor hours by the loaded rate and the in-scope percentage for variable labor, then add fixed setup and supervision. For 180 hours at $78/hr, 100% scope, plus $2,400 fixed, variable labor is $14,040 and total is $16,440.

What is a loaded labor rate?

It's the wage plus burden — payroll taxes, benefits, insurance, and shop overhead — per productive hour. It's always higher than the base wage; using base wage alone understates true labor cost and erodes margin.

Why include a billable labor scope percentage?

Not every logged hour belongs to this line item — rework, shared tasks, or partial scope may apply. The scope percent (100% here) lets you bill only the relevant fraction, here keeping the full 180 hours in the variable total.

What does the fixed setup and supervision cost cover?

One-time, quantity-independent costs: job setup, fixturing, programming, and supervisory time that don't scale with hours. Here that's $2,400, which is added on top of the $14,040 variable labor.

What is the effective hourly rate on this job?

Spreading the $16,440 total over 180 hours gives about $91.33/hr — the loaded rate plus the fixed setup amortized across the hours, which is what you should compare against the bid price.

How do I get labor cost per unit on a multi-fan order?

Run this for the whole order, then divide the total by the number of fans. The fixed setup spreads thinner over more units, so per-unit labor drops as quantity rises.

Industrial Fans, Blowers & Air Movement Equipment calculator

Labor Per Unit Calculator

Labor Per Unit builds up the total labor cost of a fan or blower job from hours, a loaded rate, the share of work actually within scope, and the fixed setup and supervision that gets spread across the order. Estimators, shop managers, and quoting engineers use it because labor — fabrication, balancing, assembly, and test — is often the largest controllable cost on a custom fan, and a sloppy labor number is what turns a winning bid into a money-losing job. Separating variable labor from fixed overhead makes the quote transparent and shows exactly where margin lives.

What this calculator does

Estimate labor cost per fan or blower from labor hours, loaded labor rate, included labor scope, and fixed setup or supervision cost.
Use it when quoting assembly, balancing, test, paint, packaging, or rework labor for industrial fans and blowers.
It computes variable labor as hours times loaded rate times the in-scope fraction, then adds a fixed setup and supervision cost for the total fan labor cost.

Formula used

Variable fan labor cost = fan labor hours × loaded labor rate × included labor scope
Total fan labor cost = variable fan labor cost + fixed setup and supervision cost

Inputs explained

Fan build labor hours:
Loaded labor rate:
Billable labor scope:
Fixed setup and supervision cost:

How to use the result

Use it when quoting or costing a fan build, balance, or assembly job and you need a defensible total labor figure including overhead.
A single blended rate hides skill mix — a job heavy on precision balancing or welding may cost more per hour than the loaded rate assumes, so check the rate against the actual crew.

Current U.S. benchmarks

As of Jun 2026, average hourly earnings in U.S. manufacturing are $30.27 (BLS), up 4.4% from a year earlier. Burdened shop rates typically run 1.3 to 1.8 times earnings once benefits and overhead are loaded.
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).
