Order enough material without guessing blind.
Enter the measured quantity, waste allowance, package size, and unit cost. The calculator estimates how much to order, how much extra you are carrying, and the material cost.

Small percentage assumptions can move material cost fast. Use this before you send a number, especially when the job has cuts, irregular rooms, damage risk, or minimum package quantities.
FAQ
How does this material waste calculator work?
Enter the measured quantity, waste percentage, package size, and unit cost. The calculator estimates the order quantity, extra material, material cost, and package count.
What waste percentage should contractors use?
There is no universal waste percentage. It depends on the trade, material, layout, cuts, site conditions, and mistake risk. Use this calculator as a planning aid and review the number before ordering.
Can this be used for flooring, drywall, roofing, and landscaping?
Yes, if the quantity unit is consistent. You can use square feet, linear feet, bundles, bags, rolls, boards, or any other unit as long as the measured quantity, package size, and unit cost use the same basis.
Why include package size?
Many materials are bought by box, bundle, sheet, bag, or roll. Package size helps estimate how many packages to buy and rounds the order up so the job is not short.
Does this replace a supplier quote?
No. This is a planning calculator. Confirm final quantities, package sizes, returns, minimum orders, and pricing with the supplier before buying materials.
