Welding & Fabrication calculator
Welding Cost per Inch Calculator
Find the welding cost allocated to each completed weld inch. You need the job cost total, matching drawing length and your target cost per inch.
What this calculator does
- Compare welding cost per completed weld inch with your estimating allowance.
Formula used
- Welding cost per inch = total welding cost ÷ completed weld length
- Welding cost per foot = welding cost per inch × 12
- Cost above target = welding cost per inch − target cost per inch
Inputs explained
- Total Welding Cost: Job ledger labor, consumables, power and allocated burden for this scope.
- Completed Weld Length: Drawing weld lengths completed within the same job cost scope.
- Target Cost per Inch: Approved estimating allowance per completed weld inch.
How to use the result
- Best suited to completed job versus weld allowance, comparing repeated weldment production runs.
- Mixed weld sizes and positions make one average unsuitable for estimating individual joints. Includes repair cost only when it is already in your job total.
Current U.S. benchmarks
- The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
- U.S. iron and steel import customs value ran $2.2B in Aug 2026 (Census International Trade). The U.S. ran a trade deficit of $0.6B in the category that month. This dollar total mixes price, quantity, product mix, origin, and timing; it does not measure physical import volume or prove a tariff or reshoring effect.
- The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
Common questions
- Do I count every pass in a multipass weld? Count the completed joint length once. Its total cost already includes every pass; counting passes again understates cost per finished weld inch.
- Should I include setup and inspection? Include them when your estimating allowance includes them. Keep the actual job total and target on the same welding scope for a useful comparison.
- Why is a large fillet more expensive per inch? A larger fillet usually requires more deposited metal and work per finished inch. Compare similar sizes and positions, or separate the job into weld groups.
- Can I quote from this average? Use it for repeated work with comparable weld scope. For a different joint size, access condition or inspection requirement, build a fresh time and consumable estimate.
