## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/us/tile/?roomLength=10&roomWidth=12&tileLength=12&tileWidth=12&wastePercent=10&unitCost=3&laborCost=480&deliveryCost=25&costSpreadPercent=15

## Inputs
- unitSystem: Dimension units; type=select; optional; default=imperial; values=imperial|metric
- roomLength: Room length (ft / m); type=number; optional; default=10
- roomWidth: Room width (ft / m); type=number; optional; default=12
- tileLength: Tile length (in / cm); type=number; optional; default=12
- tileWidth: Tile width (in / cm); type=number; optional; default=12
- wastePercent: Purchasing allowance (%); type=number; optional; default=10; min=0; max=100
- unitCost: Material price (USD / tile); type=money; optional; default=0; min=0
- laborCost: Total labor allowance (USD); type=money; optional; default=0; min=0
- deliveryCost: Delivery allowance (USD); type=money; optional; default=0; min=0
- costSpreadPercent: Low/high variation around entered subtotal (%); type=percent; optional; default=15; min=0; max=100

## Outputs
- tiles: Whole tiles to buy; format=number; primary
- area: Floor area (ft²); format=number
- squareMetres: Floor area (m²); format=number
- materialCost: Material cost; format=currency
- laborCost: Labor allowance; format=currency
- deliveryCost: Delivery allowance; format=currency
- unitRate: Entered USD rate / tile; format=currency
- estimatedTotal: Entered subtotal; format=currency
- costLow: Low budget scenario; format=currency
- costMid: Middle budget scenario; format=currency
- costHigh: High budget scenario; format=currency
- pricingStatus: Pricing status; format=text

## Formula
Tiles needed = surface area ÷ tile area × (1 + waste percentage), rounded up.; material = unrounded purchase quantity × entered unit price; middle = material + labor + delivery; low/high = middle × (1 ∓ variation/100)

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
