House Construction Cost Calculator
Estimate a house construction budget using total built-up area and your local construction rate.
How this calculator works
Base Cost = Built-up Area × Construction Rate.
Total Estimate = Base Cost + Contingency Allowance.
The calculator does not hard-code a market rate because labour, material quality, location, design and finishing can change construction cost significantly.
Example
For a 1,200 sq ft house, enter the current local construction rate quoted for your specification. A 5% contingency can then be added for planning.
Frequently asked questions
Why is no default cost per square foot provided?
Construction rates change by city, specification, labour cost and material quality. Enter a current local rate for a more useful estimate.
Does this include land cost?
No. It estimates building construction only.
Does this include architect and approval fees?
Only if your entered rate already includes them. Otherwise add those costs separately.
