Total with Markup vs Quantity Needed
公式
How to Estimate Material Costs
Formula
Total = Quantity x Unit Cost x (1 + Waste%/100) x (1 + Markup%/100)
Waste factor accounts for cuts, breakage, defects, and installation waste. Markup covers your profit and overhead on materials.
计算示例
500 square feet of tile at $12/sq ft with 10% waste and 25% markup.
- 01Base material cost = 500 x $12 = $6,000
- 02Cost with 10% waste = $6,000 x 1.10 = $6,600
- 03Total with 25% markup = $6,600 x 1.25 = $8,250
- 04Quantity to order = 500 x 1.10 = 550 sq ft

How much waste factor should I add?
