How the estimate is built

Area times a per-square-meter material rate gives the materials cost; labor is added as a percentage of materials; a contingency buffer covers the surprises every renovation hides. Each project type presets a typical material rate which you can override with real quotes.

The breakdown shows every line so you can see exactly where the money goes.

Treat it as a ballpark

Rates vary wildly by region, material choice and contractor. Use this to sanity-check quotes and set a budget ceiling, then get at least three written quotes before committing.

Never skip the contingency: industry guidance is 10 to 20%, and older homes deserve the top end.

Renovation Calculator FAQs

How accurate is this estimate?
It is a ballpark for budgeting, not a quote. Real costs depend on your region, material choices and contractor rates. Always get three written quotes before committing.
Why include a contingency buffer?
Renovations almost always uncover surprises: rot, wiring, plumbing. A 10 to 20% buffer is standard industry practice so one surprise does not sink the budget.
What does the project type change?
It presets a typical material cost per square meter for that kind of work, from basic painting to full kitchen remodels. Override it with your own rate if you have quotes.
How is labor estimated?
As a percentage of material cost, defaulting to 60%. Labor-heavy jobs like tiling run higher; material-heavy jobs like flooring run lower. Adjust to match your quotes.
Can I use feet instead of meters?
The tool works in meters. Convert feet to meters first by multiplying by 0.3048, or work in square feet and convert the final area.
