Free Material Cost, Waste and Markup Calculator
Work out what material really costs for a job, including waste, then the price to charge. Price by the unit, box, square foot, sheet or roll, the same way Universal Workflow prices a quote. No sign-up needed.

How the calculator works
Per unit: units to buy = pieces needed × (1 + waste ÷ 100), rounded up; cost = units × price.
Per box or pack: pieces with waste, rounded up; boxes = pieces ÷ pieces per box, rounded up; cost = boxes × box price. The leftover pieces stay in stock.
Per square foot: area = width × height × quantity ÷ 144; cost = area × (1 + waste ÷ 100) × price per sq ft.
Per sheet or roll: the pieces are laid out both ways round and the layout that fits more is kept. Waste is the cut gaps plus any leftover strip no wider than “keep offcuts over”. The job pays for the material its pieces use plus their share of that waste, at the sheet’s (or roll’s) price per square foot. Larger offcuts go back on the rack and aren’t charged.
Selling price: cost × (1 + markup ÷ 100), or cost ÷ (1 − margin ÷ 100) for a target margin.
Worked example: 10 panels from 4 × 8 sheets
| Sheet: 48 × 96 in at $62.00 ($1.94 per sq ft) | $62.00 / sheet |
| Pieces 24 × 36 in, 1/4 in cut gap: 3 fit per sheet when turned sideways | 4 sheets |
| Waste: cut gaps + the 12 in strip down the side (31.1% of the material used) | 27.08 sq ft |
| Material the panels use: 60 sq ft + 27.08 sq ft waste | $168.72 |
| Selling price with a 35% markup | $227.78 |
| If the job pays for 4 whole sheets | $248.00 |

Every way you buy material, in one library
In Universal Workflow, each material in your library is priced the way you buy it: by the unit, box, square foot, sheet or roll, with its cut gap, offcut size and markup saved. Add it to a quote and the price is worked out for you, with a line-by-line explanation. See estimating.
FAQ
Questions about material cost and waste

How do I work out material waste?
For sheets and rolls, lay the pieces out: count how many fit, then add up the cut gaps and any leftover strip too small to reuse. That is the waste. For flooring, tile, hardware and other stock you buy by the unit, box or square foot, add an allowance instead, often 5–15% depending on the material and the cuts.
How many pieces can I cut from a 4 × 8 sheet?
It depends on the piece size, the blade gap and which way round the pieces go. A 4 × 8 sheet (48 × 96 in) fits three 24 × 36 in pieces with a 1/4 in cut gap when the pieces are turned sideways, and only two the other way. The calculator tries both and keeps the better layout.
What is kerf?
The width of material the saw, router or cutter removes with each cut, often 1/8 to 1/4 in. It is small per cut, but it adds up across a sheet and decides whether one more piece fits.
Should the customer pay for offcuts?
Scrap they caused, yes: cut gaps and strips too small to reuse. A big offcut that goes back on the rack is stock for another job, so this calculator doesn't charge it. If you can't reuse it, price from the whole-sheet or whole-roll figure.
Should I use markup or margin?
Either, as long as you know which one you mean. Markup is profit as a share of cost; margin is profit as a share of the price. A 35% markup gives a 25.93% margin; to keep a 35% margin you need a 53.85% markup.
