Worked planning example
A 12 × 15 ft room is 180 ft². With 10% waste, plan for about 198 ft² before rounding to full boxes.
Common uses

- Hardwood planning
- Comparing box prices
- Early renovation budgets
How to get a better estimate
Measure the actual project rather than relying on listing dimensions. For irregular spaces, split the surface into simple measurable sections and add the results. Use the exact product label for package coverage, yield, density or square-foot coverage whenever it is available.
Keep waste and package rounding as separate steps. Waste covers cuts, breakage, pattern matching and unavoidable offcuts. Package rounding reflects the fact that many materials are sold only in complete bags, boxes, bundles or cans.
Before you buy: this page is a planning guide, not a contractor quotation or structural design. Verify final quantities with the product manufacturer, supplier or installer when project conditions could materially change the result.
Flooring Cost Calculator FAQ
Does this include labor?
No. RenoMetric focuses on material planning. Labor, removal, subfloor repair, trim, delivery and tax should be budgeted separately.
Should I use price per box or per square foot?
Use the unit your supplier actually quotes. If flooring is sold by the box, round the material quantity to complete boxes before multiplying by price.
How much waste should I add?
Ten percent is a common planning starting point for straightforward rooms, but diagonal layouts, patterned installs and complex cuts can require more.
