Paint Coverage Math

  • 1 gallon covers ~350 sq ft (1 coat, primed surface)
  • Most jobs require 2 coats — multiply by 2
  • Add 10% waste factor
  • Premium paints (Sherwin Williams Emerald, BM Aura): $75-$95/gal
  • Mid-tier (Cashmere, Regal Select): $45-$65/gal
  • Contractor-grade: $25-$40/gal

Time Estimates (Pro)

  • Cutting in: 80-120 lin ft/hr
  • Rolling walls: 200-300 sq ft/hr (1 coat)
  • Spraying exterior: 600-900 sq ft/hr
  • Doors (both sides, prep + 2 coats): 60-90 min each
  • Cabinets (full kitchen, prep + spray): 24-40 hrs labor

Sample Bid Math (Interior, 2,000 sq ft home)

Walls only, 2 coats, mid-quality paint:

  • Paint (2,000 sq ft walls / 350 = 5.7 gal × 2 coats × 1.1 waste = 12.5 gal × $50): $625
  • Supplies (caulk, plastic, drop cloths, tape): $250
  • Labor (2 painters × 4 days × 8 hrs × $42 burdened): $2,688
  • Cost: $3,563
  • 40% margin → $5,938 (~$3/sq ft)

Target Margins

  • Survival: 30-40%
  • Healthy: 40-50%
  • Top-tier: 50%+

Bid Mistakes That Lose Money

  1. Underestimating prep. Repairs, sanding, caulking eat hours. Walk every wall before quoting.
  2. Skipping the customer's color choice impact. Dark over light = 3 coats. Always.
  3. Not pricing per-coat for difficult colors
  4. Forgetting trim color changes. Adds days.
