Home Project Cost Calculators
Every one of these calculators follows the same honest model: you set the quantity, you set the unit price, and the tool shows you the total, the split between materials and labour, and a planning band either side of your number. National unit prices come pre-filled so you can start immediately, but they are always editable — your region, your season and your site access decide the real price. Nothing here is a contractor quote, and nothing is sent anywhere: the maths runs in your browser.
Quick answer: This category holds 18 free calculators. Each one takes your measurements and unit prices and returns an order quantity or cost estimate in your browser — nothing is uploaded and no account is needed.
