How to Use This Calculator
  1. Enter total wall area (sq ft) and ceiling area for the commercial space.
  2. Input the number of doors and windows so their area is deducted automatically.
  3. Set the number of coats and manufacturer-rated coverage per gallon (sq ft).
  4. Review Paintable Area, Gallons Needed, Primer Gallons, and Estimated Material Cost.
  5. Use Estimated Labor Hours to build your crew schedule and project timeline.

What each input means

Total Wall Area
Combined area of all walls to be painted.
Ceiling Area
Total ceiling area to be painted.
Number of Doors
Each standard door deducts ~21 sq ft from paintable area.
Number of Windows
Each standard window deducts ~12 sq ft from paintable area.
Number of Coats
Typically 2 coats for full coverage on commercial jobs.
Coverage per Gallon
Manufacturer-rated coverage per gallon (typically 300-400 sq ft).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Total Wall Area = 5000, Ceiling Area = 2000, Number of Doors = 10, Number of Windows = 15 = 6 input(s) provided
  2. Calculate Paintable Area
    Paintable Area
    6610 = 6610
  3. Calculate Paint Gallons Needed
    Paint Gallons Needed
    38 = 38
  4. Calculate Estimated Material Cost
    Estimated Material Cost
    2565 = $2,565
  5. Calculate Primer Gallons
    Primer Gallons
    19 = 19
  6. Calculate Estimated Labor Hours
    Estimated Labor Hours
    88.13 = 88.13
