About this calculator
The Budget Reform Calculator estimates the total cost of a home renovation based on the area to be renovated (in square meters) and the cost per square meter. Enter the space size and the average price per m², which varies depending on the type of work, materials, and region. The calculation is straightforward: Total Cost = Renovation Area × Price per Square Meter.
This tool is ideal for planning apartment, house, or specific area (e.g., kitchen, bathroom) renovations. It works with regular areas (rectangular, square) and can help negotiate with professionals or contractors. However, additional costs like permits, labor, or structural changes must be calculated separately.
For accuracy, measure the area with a tape measure or measurement app. The price per m² ranges from $100 (basic repairs) to $300+ (full renovation with premium materials). Always request quotes from at least three professionals for realistic comparisons.
Use this calculator to compare renovation vs. new construction costs. For example, a 6m² kitchen renovation at $160/m² costs $960, while building a new one may vary based on structural complexity. Reserve 10-20% of the budget for unexpected issues like waterproofing or hidden repairs.
