Renovation Cost Calculator per Square Meter
Enter the renovation area and the estimated cost per m² to calculate the total value.
Multiplies the area by the cost per m² and already adds a contingency margin — because renovations going over budget is the rule, not the exception, and planning without that margin usually gets expensive later.

Simplified estimate — the real cost of a renovation varies by region, finish quality, labor and the project's specific scope. Get real quotes from professionals before deciding based only on this estimate.
Frequently asked questions
Where do I get the cost per m²?
The best way is to get a quote from an architect, engineer or contractor in your area — the cost per m² varies a lot depending on finish quality (basic, mid-range, high-end) and location.
Why add a contingency margin?
Renovations involve mid-project discoveries (a hidden structural issue, a material price hike, a scope change) that almost always increase the original cost — 15% to 25% is a common range used as a buffer.
Does this value include the design fee and labor?
It depends on what you put into the 'cost per m²' you entered — if the quote you received already includes design and labor, the result does too. If it's materials only, the result reflects materials only.
