About DIY Home Calculator
Free, accurate renovation cost calculators to help homeowners plan projects with confidence — before spending a penny.
Why We Built DIYCalc
Starting a renovation without knowing what it will cost is one of the most stressful experiences a homeowner can face. Contractors are expensive to engage before you're ready, supplier quotes take days to arrive, and generic "average cost" articles online are usually too vague to be useful for your specific project in your specific city.
We built DIY Home Calculator to solve exactly this problem: give homeowners an instant, regionally accurate starting point before making any commitments. Enter your room dimensions, pick your country and city, and get a realistic cost estimate in seconds — for free, with no account required.
What We Cover
We currently offer two calculators — a Flooring Cost Calculator and a Paint Cost Calculator — covering 24 regional pricing rates across the US, UK, Canada, and Australia. Both calculators include live room/wall visualization, regional pricing, and instant real-time updates.
Our Guides section covers everything from measuring rooms correctly to the most common budgeting mistakes. Our free templates help you track costs and evaluate contractors before signing anything.
Our Editorial Standards
All pricing data is sourced from regional trade associations, government construction indices (US BLS, UK ONS, Statistics Canada, ABS Australia), and verified contractor surveys. We do not accept payment to influence our calculator rates or editorial content. See our Editorial Policy for full details.
What's Coming
We plan to add 30+ calculators covering every major DIY trade — tile, wallpaper, concrete, drywall, roofing, and more — with regional coverage expanding to 50+ countries. If there's a calculator or region you'd like to see, tell us.
