What this calculator does

Instead of a guessed sq.ft rate, it works out the mason labour cost from the actual work in your building — the same unit method our engineers use.

1. Enter the quantitiesRoof slab area, columns, beams, brick walls, loft, steps, doors & windows.
2. Check the day ratesThe daily wage for each labour type (mason, helper and others). Sample rates are filled in — change them to your local rates.
3. Get the labour costEach item is turned into labour days and priced, then the mason's margin is added — giving the labour contract amount and the rate per sq.ft.

Tip: the calculator opens with sample values for a 1,245 sq.ft house. Replace them with your building's numbers.
