Decorating Cost Calculator

This room decoration calculator is designed to give you an idea of the cost of improving the decor of any room in the house. To work out the final price you will need to tell us the size of the room (length, width and also the height from the skirting board to the ceiling, how many windows in the room need painting or staining (PVC obviously doesn't), how much you are willing to spend on a typical 5 litre tin of emulsion and whether you want the ceiling painting.

About the calculator

The estimate it will give you assumes its a pretty simple decorating job, so it won’t take hours of sanding down or half-a-day moving furniture. The room is clear the surfaces pretty good and paints and everything is ready to go.

Assumptions in calculating decorating costs:

Our figures are calculated from a mixture of personal experience, a lot of user submitted information and private research, but we still have to make some assumptions.

  • Quantities of paint are rounded up to the nearest litre e.g. 0.2 litres will be reported as 1 litre.
  • A rough average size of a window of 1200mm x 1300mm.
  • A rough average size of a door of 750mm x 2000mm.
  • We assume that emulsion (vinyl or matt) paint for walls and ceilings will cover about 10m2. Some are more some are less.
  • We assume that gloss paint for doors and windows will cover about 14m2. Some are more some are less.
  • An hourly rate for decorators of £35.
  • We have had to make informed estimates for the time take taken to do certain painting tasks, like a window or a m2 of wall.
