How much does painting cost?
Enter the measured area in square feet, then use local material and labor inputs. For example, 1,200 sq ft at $0.45 material and $2.50 labor per sq ft with 5% waste estimates about $3,717.
Start with paintable area
Cost estimates are only as useful as the measured area. Measure walls, siding, cabinets, wallpaper, or fence surfaces separately when surface type, prep level, or labor rate changes.
What changes the price
Prep, repairs, scraping, sanding, height, access, masking, color changes, primer, coatings, minimum charges, and local labor markets can change the final quote.
Use this as a planning estimate
The calculator separates the math from the quote. Use it to compare scenarios, then confirm scope, prep, materials, and site conditions with a painter.
Painting cost example checks
Examples use broad combined material and labor planning inputs. Replace them with local prices before budgeting.
| Project example | Paintable area | Planning cost |
|---|---|---|
| Small room | 384 sq ft | $1,018 |
| Large room | 560 sq ft | $1,484 |
| Interior project | 1,200 sq ft | $3,540 |
| Exterior project | 2,400 sq ft | $9,240 |
Painting square-footage examples
Examples estimate wall area before subtracting openings. Calculate rooms or exterior wall sections separately when dimensions change.
| Example | Formula | Wall area |
|---|---|---|
| 10 ft x 12 ft room | 2 x (10 + 12) x 8 | 352 sq ft |
| 12 ft x 12 ft room | 2 x (12 + 12) x 8 | 384 sq ft |
| 12 ft x 16 ft room | 2 x (12 + 16) x 8 | 448 sq ft |
| 40 ft x 30 ft exterior footprint | 2 x (40 + 30) x 9 | 1,260 sq ft |
Before you calculate
- Measure paintable area before entering per-square-foot pricing.
- Separate rooms, exteriors, cabinets, trim, fences, decks, ceilings, and specialty coatings when pricing differs.
- Keep prep, repairs, height, access, and color changes visible as separate scope notes.
Common mistakes
- Pricing from floor area instead of paintable wall or surface area.
- Ignoring prep, repairs, primer, masking, access, and minimum charges.
- Using one labor rate for surfaces that need different prep or coating systems.
Formula
cost = area * (1 + wastePercent / 100) * (materialCostPerSqFt + laborCostPerSqFt)
Assumptions
- Coverage changes with product, surface texture, primer, color change, coats, and surface condition.
- Openings, trim, repairs, masking, and separate coatings should be estimated separately.
- Use the selected product label and a realistic coat count before buying.

How to estimate compost tumbler pad floor coating cost
- Measure the project area in square feet.
- Enter editable material cost and labor cost per square foot.
- Add waste or planning buffer when material quantity changes with cuts or layout.
- Multiply adjusted area by the combined cost rate.
- Use local quotes and project scope notes before treating the result as a budget.
Before you buy materials
- Use the result as a planning number before requesting quotes.
- Confirm scope, prep standard, coatings, number of coats, and local pricing before budgeting.
FAQ
How do I estimate painting cost?
Measure the project square footage, enter material cost per sq ft and labor cost per sq ft, then add waste or touchup allowance.
How much does it cost to paint 1,200 sq ft?
With $0.45 material and $2.50 labor per sq ft, 1,200 sq ft is about $3,540 before waste. With 5% waste, it is about $3,717.
Does this include prep and repairs?
Only if you include those costs in the labor or material inputs. Patching, sanding, scraping, priming, masking, access, and repairs can be separate.
Should ceilings, trim, cabinets, and fences be priced separately?
Yes. They often use different prep, coatings, labor rates, and coverage assumptions, so separate estimates are clearer.
