Painting budget estimator
Estimate the full budget (materials and a decorator's labour) for painting a room or area — for a materials-only quantity, use the Build paint coverage calculator instead.

Estimated budget
How to use this tool
- Measure the area to be painted.
- Enter a supply-and-fit rate per m² from a quote or use the editable example rate as a scenario.
- Read the estimated total budget.
Assumptions
- The £12/m² default is an illustrative starting input, not a researched market rate. Actual paint quantity and labour depend on the paint's coverage, number of coats, surface condition and local quote.
Technical details: what the fields mean
- Area to paint
areaM2 - Total area to be painted, in square metres.
- Supply + fit rate (check local quotes)
costPerM2Gbp - Combined materials and decorator labour rate per m². The £12 default is illustrative, not a typical or live market rate; replace it with a local quote.
Methodology
Scenario budget = area × the combined supply-and-fit rate entered. The calculator does not separately model coats, paint coverage, surface preparation or trim.
Worked example
Illustrative 20m² room at £12/m²
Inputs: Area to paint: 20 m², Supply + fit rate (check local quotes): £12/m²
Result: £240 scenario budget, not a decorator quote.
Practical guidance
- If you're doing the painting yourself, use the Build paint coverage calculator for materials-only cost instead of this labour-inclusive estimate.
- For a like-for-like quote check, confirm whether the measured area and rate cover ceilings, trim/woodwork, surface preparation, number of coats, materials and labour; these are not itemised separately here.
Common mistakes
- Using this labour-inclusive estimator when you only want DIY material quantity; use the Build paint coverage calculator for paint volume.
FAQs
How can I estimate paint quantity separately?
Use the Build paint coverage calculator with the product's stated coverage, surface area and coat count. This Home tool estimates a combined budget from one entered rate.

A scenario estimate, not a decorator quote. Separate paint, preparation, number of coats, trim and labour amounts can differ from the single combined rate entered.
This tool provides an indicative estimate, based on the assumptions stated above.
