Important: This calculator is for preliminary budgeting only. It excludes land purchase unless you add it separately, and it does not replace drawings, specifications, a measured bill of quantities, site investigation, statutory advice, engineering design or a professional quantity surveyor's cost plan. Actual costs can change materially with location, soil/foundation conditions, building form, specifications, services, exchange rates, labour, logistics and market prices.

How the estimate works

Total floor area is multiplied by the editable base rate, finish factor and location factor. The selected project-scope factor is then applied. Professional/approval and external-works allowances are added, followed by contingency. Finally, the calculator presents an uncertainty range around the central planning estimate so an early-stage estimate is not presented as a precise quotation.
