Ten calculators, no spreadsheet. Estimate paint, tiles, flooring, wallpaper, concrete, plasterboard, carpet and tile adhesive — then build a room-by-room budget and generate a clean printable quote. All in your browser. No sign-up, nothing to install.
Work out how much paint you need for a room, including coats and a doors/windows deduction.
How many tiles and boxes you need for a floor or wall, with a waste allowance for cuts.
Boxes of laminate, vinyl, or hardwood planks needed to cover a room, with cutting waste.
Rolls needed for a room, accounting for pattern repeat and standard roll size.
Volume of concrete or screed for a slab, base or footing — plus how many premix bags and the cost.
Sheets of plasterboard for walls or ceilings, with screws and joint compound to finish.
Broadloom carpet is sold by roll width, so the room's narrow dimension creates waste. This works out the real metres you'll pay for.
How much adhesive (bags) and grout (kg) to lay and finish a tiled area. Pairs with the Tile Calculator.
Build a room-by-room budget, add a contingency, and see the total. Saved automatically in your browser.
