How to Price a Painting Job: From Quick Estimate to Confident Quote
Two painters walk the same job. One quotes $2,400, the other $3,600. Neither is guessing worse than the other — one of them priced the condition, and one priced the walls.
Every painting quote is answering the same three questions: how many hours will this take, what will the materials cost, and what is an hour of my crew worth? Painters who price well don't have better instincts — they have a method that answers those questions the same way every time. Here it is, end to end, with a worked example you can check against your own jobs.
Step 1: Painting hours come from a production rate
The core arithmetic is hours = area × coats ÷ production rate. On a standard repaint — sound walls, roller-led, normal cutting in — one painter covers roughly 15 m² (160 ft²) an hour. Big open surfaces run faster; fiddly, detailed work runs slower. So 120 m² (1,290 ft²) of wall at two coats is 240 ÷ 15 = 16 hours of painting.
Notice what this replaces: the per-square-meter price. A single $/m² rate looks convenient, but it silently bundles condition, coats, detail and access into one number — which is why per-meter quotes hold up on typical jobs and quietly lose money on everything else. Price the hours; sanity-check the per-meter figure afterwards if you like.
Step 2: Prep hours come from the condition — not the coat count
Preparation is 30–50% of total labor on a normal repaint, and more on weathered exteriors. It prices as its own production rate, by condition:
| Condition | What it looks like | Prep rate (approx.) |
|---|---|---|
| Near-new | Light sand and dust down, minimal filling | ≈ 52.5 m²/hr (565 ft²/hr) |
| Typical repaint | Wash, sand, fill, spot prime | ≈ 25 m²/hr (270 ft²/hr) |
| Weathered | More filling, minor repairs, some scraping | ≈ 16 m²/hr (170 ft²/hr) |
| Rough | Widespread scraping and filling, primer spots | ≈ 10.5 m²/hr (115 ft²/hr) |
Two things matter here. First, a slower rate means more hours — condition is the biggest swing factor in the whole quote, and it's the one a drive-by look gets wrong most often. Second, prep happens once, before the first coat. A three-coat job does not need 50% more sanding than a two-coat job on the same wall. If your quoting habit multiplies prep by coats, your multi-coat jobs have been over-priced and your one-coat refreshes under-priced. And prep does not speed up because the job does: spraying a wall does not sand it, so the application method belongs in the painting rate, never in the prep rate.
Step 3: Paint from spread rate, rounded to real tins
Typical wall paint spreads at about 12 m² per liter per coat (roughly 490 ft²/gal). Our 240 m² of coated area needs 20 liters — then add about 10% for cutting in, roller and tray loss, and touch-ups, and round up to containers you can actually buy: 22 liters (about 5.8 gallons) becomes a 20 L drum plus a 2 L tin. Materials then carry their own margin, typically 20–30%.
The worked example, assembled
Figures use $ as a generic unit — the ratios hold in any currency. 120 m² (1,290 ft²) of typical-condition wall, two coats, charge-out rate $90/hr:
- Painting: 240 ÷ 15 = 16.0 hrs
- Prep (typical): 120 ÷ 25 = 4.8 hrs
- Labor: 20.8 hrs × $90 = $1,872 — about 1.3 days for a two-painter crew
- Paint: 22 L (about 5.8 gal) bought at $20/L = $440 cost, ≈ $587 at a 25% margin
- Estimate: ≈ $2,460, with an honest range of about $2,190–$2,830
Why a range? Because the real uncertainty in a quick estimate is how fiddly the job turns out — pricing the same job half a production step faster and slower gives you a defensible band, not false precision. You can run your own numbers in the free painting quote calculator, which applies exactly this method.
When the estimate is enough — and when it isn't
A range like that is a credible opening figure on the phone or at a first walk-through, and it will tell you quickly whether the client's budget is on the same planet. What it cannot be is a contract price. The items that decide where in the band a job lands — trim meters, ceiling heights, access setup, condition up close — only show up in a surface-by-surface measure. That's the difference between an estimate and a quote, and it's where under-priced jobs lose their margin: not on the walls, but on the skirting boards nobody counted and the scaffold nobody priced.
So use the method both ways. Quick estimate to qualify the job and anchor the conversation; full measure to commit a number. Surfacely's whole premise is making the second part as fast as the first — measure the site on your phone and the quote prices itself from your rates, your production ladder, and the condition you recorded standing in front of the wall.
