Welding Cost Calculator
A welding quote is not one number. It is labour time, filler and gas, machine time, and shop overhead, all stacked on the same job. This calculator takes weld length, process, position, thickness and your hourly rates, estimates the welding time from them, and returns a full cost breakdown with a total and a cost per foot.
Estimate only. The tool sums unrounded values and then rounds each line to two decimals, so adding the rounded lines can differ by a cent from the rounded subtotal. Base metal, inspection, travel, permits, taxes and profit are not included: add them separately before quoting.
Quick Answer
A 20 foot MIG weld in flat position on 0.25 inch material, at $45 per hour labour, $2.50 per foot consumables, $8 per hour gas and $6 per hour equipment, with 0.5 hours setup and 15% overhead, costs $1,251.25 in total, or $62.56 per foot. Welding time is 17.09 hours and total time including setup is 17.59 hours. Read the warning below before quoting from that time figure, because it comes from the tool's own slow speed model.
Read this before you quote: three quirks that move the answer
- The speed model is slow. The tool starts from 12 inches per hour and adjusts it by process, position and thickness. That gives about 1 foot per hour for the worked example, far slower than a real MIG travel speed. Labour, gas and equipment all scale with that time, so the total inherits the slowness.
- Material type changes nothing. The dropdown is required, but the code never reads it for math. Identical inputs with mild steel or titanium give identical costs. Price the base metal and any alloy premium yourself, outside the tool.
- Zero is not zero. A blank or zero setup time becomes 0.5 hours, and a blank or zero overhead becomes 15%. If your job genuinely has no setup or no overhead, the tool still charges those defaults.

How to use the welding cost calculator
Fill in the job, then read the breakdown line by line. The results stay hidden until you calculate.
- Pick process, material and position: all three dropdowns are required, even though only process and position affect the math. MIG, mild steel and flat position are pre-filled from the worked example.
- Enter length and thickness: 20 feet and 0.25 inch are pre-filled. Length drives time and consumables; thickness slows the speed multiplier.
- Enter your rates: welder rate per hour, consumables per foot, gas per hour and equipment per hour. Gas and equipment are charged on total time including setup, while consumables are charged on length only.
- Set setup and overhead: 0.5 hours and 15% are pre-filled. Remember the fallback rule above if you clear either field.
- Click Calculate cost: welding time, total time, each cost line, subtotal, overhead, cost per foot and total appear together. Copy or share the breakdown from the buttons in the results box.
If a dropdown is empty, or length or thickness is zero or blank, the tool shows "Please fill in all required fields" and no results. Rates left blank count as zero, which is why a run with no rates returns $0.00 across every cost line while still showing a time.
The welding cost formula
The tool works in three steps: time first, then cost lines, then overhead. Time is the step that deserves the most attention, because every time-based charge follows it.
Welding time = (length in feet x 12) / adjusted speed
Total time = welding time + setup time
Labour = total time x welder rate; Gas = total time x gas rate; Equipment = total time x equipment rate
Consumables = length x consumables per foot
Subtotal = labour + consumables + gas + equipment; Overhead = subtotal x overhead percent
Total = subtotal + overhead; Cost per foot = total / length
| Multiplier | Values in the tool |
|---|---|
| Process | MIG 1.2, TIG 0.8, stick 1.0, flux-cored 1.1, submerged arc 1.5, spot 2.0, plasma 0.9 |
| Position | Flat 1.0, horizontal 0.9, vertical 0.7, overhead 0.6, pipe horizontal 0.8, pipe 45 degrees 0.7 |
| Thickness | Maximum of 0.3 and (1 minus (thickness minus 0.125) times 0.2). At 0.25 inch that is 0.975; at 4 inches it hits the 0.3 floor. |
Worked example arithmetic, so you can check it: adjusted speed is 12 x 1.2 x 1.0 x 0.975 = 14.04 inches per hour. Welding time is 240 inches / 14.04 = 17.09 hours. Total time is 17.59 hours. Labour is 17.59 x $45 = $791.73, consumables are 20 x $2.50 = $50.00, gas is 17.59 x $8 = $140.75, equipment is 17.59 x $6 = $105.56. The subtotal is $1,088.05, overhead at 15% is $163.21, the total is $1,251.25, and cost per foot is $1,251.25 / 20 = $62.56. One rounding note: the tool adds unrounded values, so the rounded lines sum to $1,088.04 while the rounded subtotal reads $1,088.05. That cent is rounding, not an error.
Worked example and sensitivity: what actually moves the total
Because time drives three of the four cost lines, process and position move the total far more than consumables do. The table below runs the same rates logic across different jobs, with every row produced by this exact tool.
| Job | Total time | Total cost | Cost per foot |
|---|---|---|---|
| Worked example: MIG, flat, 20 ft, 0.25 in, $45/hr, 15% overhead | 17.59 hr | $1,251.25 | $62.56 |
| TIG, overhead, 10 ft, 0.5 in, $60/hr, 20% overhead | 23.52 hr | $2,350.62 | $235.06 |
| Stick, horizontal, 10 ft, 0.125 in, $40/hr, blank setup and overhead (fallbacks apply) | 11.61 hr | $690.64 | $69.06 |
| Spot, flat, 5 ft, 4 in, $30/hr, setup 0 and overhead 0 entered (fallbacks still apply) | 8.83 hr | $361.29 | $72.26 |
| Submerged arc, flat, 100 ft, 0.01 in, $50/hr, 10% overhead | 67.17 hr | $4,745.84 | $47.46 |
The TIG overhead row is the clearest warning about position. A foot of weld that costs $62.56 flat in MIG costs $235.06 overhead in TIG, mostly because the 0.8 process multiplier and the 0.6 position multiplier together cut speed to under half, and the higher hourly rates then apply to far more hours. Before blaming the process, check whether your real travel speed justifies that time at all, given the slow base speed discussed above.
What the old article claimed, and what the tool actually does
The previous version of this article described a different, richer tool. It promised electricity costs from amps, volts and duty cycle, a profit margin, and a worked example totalling $772 from $400 labour, $60 filler, $50 gas, $30 equipment, $20 electricity, $84 overhead and $128 profit. None of those inputs exist in the live tool, and that $772 example cannot be reproduced from it. The live tool has no electricity input, no profit input, no base-metal input, no pass count and no inspection line. Its overhead is a percent of the subtotal, not a flat shop figure, and its only time input is setup time, with welding time derived from length.
This rewrite keeps the tool as coded and says so plainly. If you need a final client price, take the tool total and add base metal, inspection, travel, permits, taxes and your profit margin by hand. A guide to pricing welding jobs makes the same point from the shop side: labour, materials and overhead are the core, and the quoted price is the estimate plus a margin, not the estimate itself. Treat this calculator as the estimate step, not the quote.
What competing calculators miss
Rival welding cost tools tend to solve a different problem from this one, and the difference matters when you pick a tool:
- Time-direct tools: several rivals ask for hours directly, or for filler pounds and gas cubic feet, and price those quantities. That is more honest when you already know the time, but it gives a shop with only a drawing and a length nothing to start from. This tool derives time from length, at the cost of the speed-model caveat above.
- Hardcoded-overhead tools: one rival applies a fixed 35% overhead to labour only and a fixed markup multiplier, with no way to change either. This tool lets you set the overhead percent, but applies it to the whole subtotal, which is a different accounting choice. Neither is wrong in isolation; they are not comparable totals, so do not mix them across quotes.
- Guide pages without a tool: pipe-welding cost guides show excellent line-by-line breakdowns, including examination, mobilization and contingency, which this tool omits entirely. Use a guide like that as a checklist for what to add after the tool total, not as a replacement for it.
- Tools that hide the speed assumption: any length-to-time tool has a speed model, and most bury it. This article prints the multipliers, the base speed and the floor, because a hidden speed model is how a $62 per foot figure gets quoted without anyone noticing the time behind it.
For the filler side of the same job, the weld deposition rate calculator turns wire feed speed and diameter into pounds per hour deposited, which is the right way to size filler orders. For the labour rate itself, the shop rate calculator and the blended labor rate calculator help build a defensible hourly figure. And when consumables are bought with a markup, the material markup calculator prices that step separately.
Quoting checklist: turning the estimate into a price
Use the tool total as the starting point, then work down this list before sending anything to a client. Base metal and filler beyond the per-foot consumables rate, cutting and beveling, post-weld inspection and testing, travel and site access, permits for structural work, and taxes all sit outside the tool. So does profit: the old article's 20% profit example is a pricing step, not a tool feature, and adding it means multiplying the estimate by 1.20 yourself, or by whatever margin your shop actually targets. Finally, sanity-check the time against a job you have already done. If the tool says 17 hours for work your crew finished in 3, the speed model is the problem, not your crew, and the quote should follow your measured time, not the tool.
Frequently asked questions
It derives welding time from length: total inches of weld divided by an adjusted speed. Adjusted speed starts at 12 inches per hour and is multiplied by a process factor, a position factor, and a thickness factor. Setup time is then added to give total time.
Because the tool code reads the material dropdown for validation but never uses it in the math. Only process, position, length, thickness and your rates affect the result. Identical inputs with mild steel or titanium give identical costs, so price base metal and alloy premiums separately.
Because the tool uses a fallback when a value is blank or zero: setup falls back to 0.5 hours and overhead falls back to 15 percent. That means a genuinely zero setup or zero overhead cannot be entered. The worked sensitivity table shows a spot job where entering 0 for both still produced 8.83 hours and 15 percent overhead.
Labour on total time, consumables on length, gas on total time, and equipment on total time, summed as the subtotal, plus overhead as a percent of that subtotal. Cost per foot is the total divided by weld length. Base metal, inspection, travel, permits, taxes and profit are not included.
No. The tool has no electricity input and no profit input, even though the previous article claimed both. Add electricity through your equipment hourly rate if you wish, and add profit as a separate markup on the estimate before quoting.
You can run it, but read the result with care. Spot welding is normally priced per weld, not per foot, while this tool prices a length with the fastest speed multiplier, 2.0. For spot work, treat the output as a rough length-based comparison only.
Because the speed model starts at 12 inches per hour, which is roughly 1 foot per hour before multipliers. Real travel speeds are far higher, so the tool time will look long against shop experience. Check the time against a completed job and, if it does not match, quote from your measured time instead.
It is an estimate for the four cost lines the tool covers. A client quote still needs base metal, inspection, travel, permits, taxes and profit added, plus a time check against real shop performance. Never send the tool total alone as a firm price.
