About this calculator
Unit rate from a total price, for comparing quotes, checking your own numbers against past jobs, or quoting by area.
How it’s calculated
Rate = total ÷ area.
Worked example
With these inputs:
- Total price
- R0
- Area
- 45 m²
the result is:
- Price per m²
- R0.00
Tips from the trade
- Unit rates hide a lot. Small jobs carry higher rates because setup costs don’t shrink.
Results are estimates for planning and pricing. Check quantities against your drawings, the manufacturer’s data and SANS 10400 (the National Building Regulations) and your local municipality before ordering.
