Plan your project with clearer numbers.
RenoCalc UK makes everyday home-improvement planning easier. Our free calculators help UK homeowners, DIY enthusiasts and tradespeople estimate material quantities and costs before ordering.
Five tools for everyday renovation planning
Estimate tiles and paving packs, paint tins, plasterboard sheets, skirting lengths and door architrave stock. Enter your measurements, product sizes and allowances, then add a price to estimate the material cost.
Simple tools, practical estimates
Enter your measurements and product details to see results immediately. No account or email address is needed to use the calculators.
Check before you buy
Our tools provide estimates, not a cutting plan or professional site assessment. Check your measurements, supplier coverage and laying pattern before ordering. Tile and paving estimates exclude joint widths. Paint coverage depends on the product and surface. Board and timber quantities depend on your cutting layout. Our architrave tool uses separate stock for uprights and heads, so it gives a conservative estimate. Material costs exclude labour, delivery and installation extras.
