How the estimate works
Materials = area × material rate, adjusted for waste. Labor = area × labor rate. Total = materials + labor + additional expenses.
Assumptions and limits
Rates, hidden conditions, permits and taxes vary. Use this as a planning estimate and obtain local written quotes before committing.
This preliminary estimate is not a quotation. Local prices, taxes, site conditions, permits and contractor scope may differ.
Example
For 20 m² at 30 per m² materials, 18 per m² labor, 10% materials waste and 100 additional costs: materials 660, labor 360, total 1,120 in the chosen currency.
