Work out loading factor instantly with clear inputs, formula shown and shareable results.
Loading factor is how much the saleable area exceeds the carpet area, expressed as a percentage of carpet. Converting the quoted rate to a rate per carpet foot is the only way to compare two projects with different loading, and the difference is usually far larger than any negotiated discount.
Loading factor
Loading = saleable area / carpet area - 1
Effective rate
Rate on carpet = total price / carpet area

Several jurisdictions now require carpet area to be disclosed and prices to be quoted on it, but the loading itself is not capped. Disclosure is the protection, not a limit.
This calculator takes 3 inputs: Carpet area, Saleable area, Quoted rate. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
