Common renovation budget questions
How much does a home renovation cost?+
Home renovation costs vary enormously. A basic bathroom refresh costs €3,000–€8,000; a full kitchen renovation €8,000–€25,000; whole-house renovation €40,000–€150,000+. The biggest variables are labour rates (which differ by country) and the scope of structural work required.
How much should I budget for labour vs materials?+
For most renovation trades, labour costs 40–60% of total project cost. Tiling and plastering are labour-heavy (up to 60%); flooring installation less so (30–40%). DIY can eliminate labour costs entirely but requires time, tools and skills.
What contingency should I add?+
Add 10–20% contingency to any renovation budget. For older properties (pre-1970) or projects involving structural work, use 20%. Unexpected issues — hidden rot, outdated wiring, damp — are common and can add thousands.
How do I reduce renovation costs?+
Biggest savings: (1) do demolition and prep yourself, (2) source materials directly rather than through contractors, (3) schedule trades back-to-back to avoid mobilisation fees, (4) use mid-range materials in low-visibility areas.
How renovation costs are estimated
The method
This estimator uses typical material and labour cost ranges per m² for each trade, based on Western European market data. You enter the area and material cost per m² — the calculator adds labour based on typical labour-to-material ratios for that trade type.
Labour ratios by trade
Flooring: ~35% labour. Tiling: ~55% labour. Painting: ~45% labour. Plastering: ~60% labour. Bathroom/Kitchen fit: ~50% labour. In DIY mode, labour is excluded entirely.
Why costs vary so much
Labour rates vary 3–5× between countries (Norway vs Portugal, for example). Material quality ranges from budget to premium with 4–10× price differences. Always get 3 quotes from local contractors and use this tool to sense-check them.
