Formula
Floor area = length × width; ordered area = floor area × (1 + waste ÷ 100); total = ordered area × material price + floor area × installation price.
Worked example
The initial example uses the following assumptions. Its result is computed by the same engine as the calculator. Measurements are metric and money amounts use USD; these are illustrative inputs, not market prices.
- Room length
- 5 m
- Room width
- 4 m
- Material price
- 25 per m²
- Waste allowance (%)
- 10
- Installation price
- 10 per m²
- Estimated total: $750.00
- Material area including waste: 22 m²
- Actual floor area: 20 m²
- Materials: $550.00
- Installation on actual area: $200.00
Assumptions and limitations
Waste increases the material order, not the installed floor area in this model. Pack rounding, subfloor repairs, delivery and tax are excluded. Choose an allowance appropriate to cuts and the laying pattern.
Questions about this calculation
What changes when I increase waste?
Material quantity and cost increase; installation remains based on the actual floor area.
Can I use a fixed installation quote?
Divide a fixed quote by the measured floor area to express it as a price per unit area.
