How this calculator works
Add waste for cuts, layout, breakage, and attic stock.
For best results, measure actual jobsite dimensions, use supplier-specific coverage numbers, and choose a waste factor that matches layout complexity and field conditions.
Real-world estimating notes
Flooring and tile projects need extra material for cuts, layout, damaged pieces, and future repair. More complex patterns usually need a larger waste factor.
Before ordering
- Confirm product coverage per box or bag.
- Increase waste for diagonal, herringbone, or small-room layouts.
- Keep leftover material for future repairs.
