How to Price a Painting Job Without Losing Money
· 5 min read
Painting looks straightforward on the surface — buy some paint, roll it on, done. But anyone who's priced a painting job without thinking it through has ended up working long hours for a terrible return. Getting your pricing right requires measuring carefully, understanding your material costs, and being honest about how long prep actually takes.
Start with accurate measurements
The foundation of any good painting quote is knowing exactly how much surface you're covering. For interior walls, measure the perimeter of each room and multiply by the ceiling height to get your total wall area. Subtract door and window openings (a rough rule is to deduct 2m² per standard door and 1.5m² per average window). For ceilings, it's simply length multiplied by width. For exteriors, measure each elevation separately. Always double-check your measurements — a single room miscalculated can throw your whole quote off.
Calculate your materials properly
Paint coverage varies by product and surface. Most quality interior paints cover 12–16m² per litre for a single coat. Factor in whether you need a primer coat, and whether the surface condition requires extra coats — porous, dark, or previously unpainted surfaces often need three coats minimum. Don't forget to account for all consumables: painter's tape, plastic sheeting, sandpaper, sugar soap, brushes, roller covers, trays, and any fillers or patching compounds. These add up, and they shouldn't come out of your labour margin.
Never underestimate prep time
Prep is where most painting quotes fall apart. New painters in particular tend to quote for the painting and forget about everything that comes before it. Prep on an average interior job — moving furniture, laying drop sheets, filling holes, sanding, cleaning surfaces, and masking — can easily take as long as the painting itself. On exteriors, pressure washing, scraping, and priming can take days before a brush touches the wall. Be specific when measuring prep time and make sure it's reflected in your quote.
Price your labour correctly
Work out how many hours the job will take in total — prep, priming, painting coats, cleanup, and any touch-ups — and multiply by your hourly rate. Don't forget travel time if the job is far from home base. If you're quoting fixed-price (which most clients prefer), add a contingency of 10–15% for unknowns. On painting jobs, unknowns are common: surfaces in worse condition than expected, extra coats needed once you see the existing colour, or weather delays on exterior work.
Mark up your materials
If you're supplying paint and materials, apply a standard markup of 15–25%. You've done the legwork to specify the right product, you're managing the purchasing, and you're taking on the risk if something needs to be returned or exchanged. That's worth charging for.
Write clear inclusions and exclusions
A solid painting quote should be clear about what's included: number of coats, specific areas, paint quality (budget, mid-range, premium). And equally clear about what's not included: moving heavy furniture, repairs beyond minor filling, painting of fittings or fixtures, or touch-ups after other trades have finished. This avoids scope creep and protects your margin. Using a tool like instanttradequote makes it easy to build itemised quotes with clear line items for each area, coat, and material — so nothing gets missed.
Pricing painting jobs accurately comes down to discipline: measure everything, account for all your time (especially prep), mark up materials fairly, and build in a contingency. Do that consistently and you'll never finish a painting job wondering where your money went.
