Paint Cost Per Square Foot — Budget to Paintable Area
Who this is for: For planners working budget-first — 'I have $1,500, how much painting does that buy?' — and landlords pricing turnover turns.
Work backwards from your budget: dollars in, paintable wall square feet out — at DIY or pro rates.
Quick answer: Paint cost per square foot: DIY materials run $0.11–0.31/sq ft of wall (two coats, by paint tier); professionals run $2–6/sq ft all-in. A $1,500 budget buys ~4,000+ sq ft of wall DIY — or ~250–750 sq ft at pro rates. Enter your budget below.
US band $2–6
| DIY rate | $0.11–0.31/sqft (paint × 2 coats + supplies) |
|---|---|
| Pro rate | $2–6/sqft all-in (US 2026) |
| Room unit | ≈330 sqft of wall (12×12×8 net) |
| Example | $1,500 → ~4,300 sqft DIY / ~375 sqft @ $4 pro |
| ROI | Interior paint = top renovation ROI |
| Status | Figures follow 2026 US industry averages: pro interior $2–6/sq ft of wall area, coverage 350–400 sq ft/gal per coat, paint $15–60/gal by tier, exterior $1.5–5/sq ft. Estimates for budgeting — your local market and surface condition move the final number. |
What does painting cost per square foot?
Two rates, two answers. DIY materials: paint at $20–55/gal covering 350 sq ft per coat works out to about $0.11–0.31/sq ft of wall for two coats plus supplies — call it $0.15–0.35. Professional: $2–6/sq ft all-in (labor dominates). The calculator divides your budget by the rate and returns paintable wall area — then, usefully, converts that to rooms (a standard bedroom is ~330 sq ft of wall). Example: a $1,500 budget buys ~4,800–10,000 sq ft of wall DIY depending on paint tier, or 430–1,000 sq ft professionally — the difference between six rooms and half a room is entirely the labor line.
