Small fab shops often run 10 to 50 of a part at a time. This example makes 20 L-shaped shelf brackets, each from 20 in of 1/4 x 2 in flat bar, cut, welded, ground and painted. Here is the batch the calculator starts with, worked out the same way. It makes 20 parts at $15.61 each.
| Material | Used | Cost |
|---|---|---|
| A36 flat bar 1/4 x 2 in, 20 ft stick$28.56 for 20 ft | 400 in | $47.60 |
| Weld wire, gas, discs and paint$2.86 for 1 piece | 20 | $57.20 |
| Labour: 4 h at $35.00/hr | $140.00 | |
| Time on the machine: 2 h at $25.00/hr | $50.00 | |
| Setup, 30 minutes once per job | $17.50 | |
| Total for 20 parts | $312.30 | |

In the example on this page (steel l shelf bracket, 20 parts per batch, prices from October 2026), one part costs $15.61. That counts every material, packaging and 4 h of labour at $35.00 an hour, plus 2 h on the machine. Your cost depends on your prices and your batch size, so put in your own numbers.
Divide your cost per part by 1 minus the margin you want. With a cost of $15.61 and a 30% margin, the price is $15.61 / 0.70 = $22.31. If you also sell wholesale, check that half of that price still covers your cost.
