How To Use Paint CalculatorPaint Job Estimator is designed to provide accurate interior painting cost per sq ft for the entire house.
Prices are based on 8' ceiling height. If your ceilings are higher, you should add about 9% per additional foot to the total price.
If you do not change the Color / Ceiling setting, costs are calculated assuming application of 2 coats of light color paint on all walls, and 1 coat on all standard ceilings.
Moving or covering furniture, painting moldings, repairing wall damages, or painting doors/windows, is not included in the initial price. However, you can change these settings to include those items in the total cost.
If you want to paint rooms in darker colors, this will require more than 2 coats to get proper coverage and color saturation, thus increasing the cost.
If you have Cathedral / Vaulted ceilings, painters will have to spend considerably more time setting up staging, and getting up to paint such ceilings, thus costs will go further up.
Wall Repairs:Since every house is different, this option includes minor or major repairs. Most painters will charge per man-hour for this service, so we estimated our cost formula based on how many hours it will take to do small or large repair to sheet rock / drywall, over the entire house area.
The average cost to fix wall damages is about $40-45 / hour.
Moldings:Each house has a different type and quantity of moldings. To simplify the estimating process we include 2 options - paint floor moldings only, or no molding painting at all. If you have moldings on walls or on ceilings, you can price those at $0.65 / linear foot.
Progressive Pricing FormulaSee our demo video on progressive pricing for a painting estimate:
Most painters price their work per square foot, or entire house (horizontal square footage). However, if you are looking to paint only a small area (one or two rooms), your cost per square foot will go up, as the area goes down. As with most other home improvement projects, economy of scale determines the cost of your job.
Thus if you want to paint 2 rooms of approximately 150 sq. ft. each (300 s.f. total), you will be paying about $4 per sq. ft. However if you are painting the entire house, your base price is about $2.25 / sq.ft. for a 1 storey home with a total of 1700 s.f. of living area to be painted (including closets / staircases). A 2+ storey home of same size will cost about $2.45 / sq.ft.
However, as the house area increases, your cost per square foot goes down. For example, painting a 2400 sq. ft. house will cost $1.85 / sq.ft., and a 3000 s.f. home will cost about $1.65 / sq.ft.
To account for these price differences based on home size, we've included an intelligent progressive pricing formula that gradually changes the cost/foot, based on house size. You can test this by gradually increasing or decreasing the Home Size setting in increments of 10 / 20 / 30 sq.ft., etc.
