How to Calculate Interior Painting Quotes
Professional formulas contractors use for accurate interior paint estimates
Wall Area Calculation
Formula:
Length × Width × Height - Doors & Windows
Example:
12' × 15' × 9' = 1,620 sq ft - 120 sq ft = 1,500 sq ft
Paint Coverage
Formula:
400 sq ft per gallon (average)
Example:
1,500 sq ft ÷ 400 = 3.75 gallons needed
Labor Costs
Formula:
$1.50 - $3.50 per sq ft
Example:
1,500 sq ft × $2.50 = $3,750 labor
Time Estimation
Formula:
200-300 sq ft per hour
Example:
1,500 sq ft ÷ 250 = 6 hours work
Complete Interior Quote Formula
Materials + Labor + Overhead (15%) + Profit (20%) = Total Quote
Example: $200 materials + $750 labor + $143 overhead + $219 profit = $1,312 total
