- Spread the shop's costs over the hours a customer pays for, not the hours the lights are on.
- Consumables are a cost of every arc hour. Count them per week and the calculator turns them into dollars per billable hour.
- Price materials separately with their own markup. Steel prices move, and the shop rate should not move with them.
How to work out a welding shop rate
A shop rate has to pay the welder, the shop around them, the consumables they burn, and leave a profit. The calculator divides all of it by billable hours.
- Paid hours. Hours a week × 52. At 40 hours, 2,080.
- Billable hours. Take off paid days off, then the part of each day no job pays for: quoting, material runs, cleanup, machine upkeep. Two unbilled hours in an 8 hour day leaves 75%.
- Labor cost. Wage × paid hours × (1 + payroll taxes and comp).
- Consumables. Your weekly spend on wire, rods, gas, discs and tips × 52.
- Break-even. (Labor + shop overhead + consumables) ÷ billable hours.
- Shop rate. Break-even ÷ (1 − profit share).
Worked through with the starting numbers: one welder at $25.84 an hour (the BLS national median for welders, cutters, solderers and brazers, May 2025), 40 hour weeks, 10 days off, 2 unbilled hours a day, 7.65% payroll taxes, $60,000 of shop overhead, $150 a week of consumables and 15% profit.
| Step | Math | Result |
|---|---|---|
| Billable hours | (2,080 − 80) × 75% | 1,500 |
| Labor cost | $25.84 × 2,080 × 1.0765 | $57,859 |
| Consumables | $150 × 52 | $7,800 |
| Break-even | ($57,859 + $60,000 + $7,800) ÷ 1,500 | $83.77 |
| Shop rate | $83.77 ÷ 0.85 | $98.56 |
The employer payroll tax figure is Social Security at 6.2% plus Medicare at 1.45%, from the IRS. Add your state unemployment rate and your workers' comp rate for welding work, which your policy lists per $100 of payroll.
What welders charge per hour
Check your rate against what customers see in published guides. They are a sanity check, not a target: your costs decide your floor.
| Guide | Hourly figure |
|---|---|
| HomeAdvisor | $60 to $125 an hour to hire a local welder |
| HomeAdvisor, by process | Stick $50 to $75, MIG $65 to $95, TIG $75 to $125 |
| Thumbtack | $100 to $105 an hour on average, up to $120 |
HomeAdvisor notes most welders have a minimum service charge, usually about an hour or two of labor. Thumbtack mentions an average minimum of $60 for any welding work. If your rate comes out well above the published range, look at billable hours and overhead before cutting the profit.
Consumables: the cost that rides on every arc hour
Wire, rods, shielding gas, tungsten, contact tips, grinding and flap discs, and sandpaper get used up job after job. They are too small to bill line by line and too big to ignore.
A Texas welder quoted by Thumbtack spends $64 a week on sanding paper, $40 for a 30 pound roll of wire every one and a half to two weeks, and $120 to $150 for three bottles of flux or gas over the same stretch. HomeAdvisor lists flux or shielding gas at $40 to $50 a bottle and wire at $25 to $40 an 11 pound roll.
Put your own weekly figure in. The calculator turns it into a cost per billable hour: $150 a week over 1,500 billable hours is $5.20 an hour. Gas-hungry TIG work on aluminum or stainless burns more than MIG on mild steel, so a shop that does mostly TIG should count more.
Steel and materials: price them separately
Leave steel, tube, plate and bought parts out of the shop rate. Price them on each job at your cost plus a markup. Steel prices move, and Thumbtack's Texas welder notes his price for a 25 foot stick of 14 gauge steel has run from $44 to $50 and as high as $125.
The calculator's job pricer uses the rate it just worked out: shop hours × rate, plus materials × (1 + markup). The starting job, 6 hours with $250 of steel at a 20% markup, comes to $891.
Metal type changes both sides. Thumbtack's welder says aluminum and stainless cost 1.5 to 2 times more than standard steel, and HomeAdvisor's TIG rates run higher than MIG. Price the metal at cost and let the hours reflect the slower process.
Minimums, mobile work and rush jobs
Small jobs eat a shop's day. A broken chair leg needs the same setup, cleanup and paperwork as a gate. A minimum charge, an hour or two at your shop rate, covers it.
- Shop work. Customers drop off and pick up. Your rate covers the shop.
- Mobile work. Add a trip charge or a higher minimum for driving the truck and rig to the job, or raise the unbilled hours to count the drive.
- Rush. When a job jumps your queue, a rush share on the estimate pays for the reshuffle.
Koira estimates carry a setup fee, a minimum charge and a rush share as their own settings, with defaults from your price book, so you set them once.
Price the job and send it
Press Save as an estimate and Koira opens a draft with the labor line at your shop rate and the materials line. Customers can send photos and drawings, DXF and PDF included, through your quote form, so the picture of the broken trailer hitch sits on the job with the price. When the work is done, Koira texts them it is ready with a link to pay the invoice.
For a general version of this math without consumables, see the labor rate calculator. To see how many jobs a month cover the shop, use the break-even calculator.
