How do you calculate fabricated vessel cost?

Multiply fabrication hours by the loaded labor rate by the recovery factor, then add fixed setup cost. With 100 hours at $45, an 80% recovery factor and $250 fixed, the weighted cost is $3,850 and the per-piece value is $38.50.

What does the recovery factor represent?

It is the fraction of raw labor value you actually capture after inefficiency, rework, or contract discounts. At 80% the captured value is $3,600 of the $4,500 raw labor, before the $250 fixed adjustment.

What is a good loaded labor rate for a vessel shop?

Loaded rates for coded pressure-vessel welding commonly run $40-$90 per hour depending on region, certifications, and burden. The $45 default is a modest fully-loaded shop rate; adjust for your overhead recovery.

How is per-piece cost different from total cost?

The total ($3,850) is the cost for the whole entry; per-piece ($38.50) divides it across the quantity so you can compare batch economics or set a unit price. Fixed cost spread thinner as quantity rises.

Does this include material and NDE?

No. It captures labor and a fixed setup charge only. Add plate, heads, flanges, weld consumables, radiography, and hydrotest separately, then apply margin on the full delivered cost.

Fabricated vessel cost vs. quoted price — are they the same?

No. This is your internal cost basis; your quoted price adds material, contingency, and margin on top of the $3,850 figure.

Tank, Vessel & Pressure Equipment Fabrication calculator

Fabricated Vessel Cost Calculator

The Fabricated Vessel Cost calculation builds the labor-driven cost of manufacturing a tank or pressure vessel from shop hours, a fully loaded labor rate, a recovery factor, and fixed engineering or setup charges. Estimators and shop managers use it to turn a routing sheet into a defensible quote and to see the per-piece cost on a batch. It matters because vessel work is labor-intensive — rolling, fit-up, welding, NDE, and hydrotest — and a small error in the loaded rate or recovery factor compounds across hundreds of hours. Knowing both the total and the per-unit figure lets you price a single vessel or a production run without losing the fixed costs in the noise.

What this calculator does

The Fabricated Vessel Cost calculation builds the labor-driven cost of manufacturing a tank or pressure vessel from shop hours, a fully loaded labor rate, a recovery factor, and fixed engineering or setup charges.
Use it when fabricated vessel cost in tank, vessel and pressure equipment fabrication is being put through a tank, vessel and pressure equipment fabrication weighted-cost review.
It multiplies fabrication hours by the loaded labor rate and a recovery factor, adds fixed setup cost, and divides by quantity for a per-piece figure.

Formula used

Fabricated Vessel Cost cost = quantity × rate × capture factor + fixed cost
Per-unit fabricated vessel cost = total cost ÷ quantity

Inputs explained

Vessel fabrication hours:
Loaded shop labor rate:
Billable/recovery factor:
Fixed engineering and setup cost:

How to use the result

Use it when quoting a vessel or a batch, comparing make-vs-buy, or checking that a routing's booked hours recover shop overhead.
It is a labor-and-fixed-cost model; it does not include plate, forgings, flanges, or consumables, so add material separately for a full delivered cost.

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.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
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 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
