Common ways to charge for painting include per square foot, per hour, per room, and per day. Average costs vary depending on the painter's experience level, type of job, season, and location. Basic interior painting typically costs $3 to $6 per square foot.
Some contractors use a rough base rate of $1.50 or $2.00 per square foot, some multiply 4 to 6 times the paint cost, some estimate the time the job will take and add it to an estimate of materials—and some may simply offer the lowest price to outbid the competition.
(Height x Width) × Price per square inch
This formula is used for flat, two-dimensional work, like paintings, prints and drawings. It's also pretty straight forward: it takes the surface area of a work and multiplies by a rate of your choosing. Determining the price per square inch is the tricky part.
Calculate Your Labor Cost
The average cost of painting labor is $20 an hour per person. Your labor cost will depend on how many workers you need to do the job and how long it will take them to complete.

To estimate the square footage, you multiply length x width. For example: If you are painting a bedroom, you should measure from corner to corner of a wall and then measure the height. So if your wall is 12 ft wide and 8 ft high, that wall is 96 square feet.
Multiply the painting's width by its length to arrive at the total size, in square inches. Then multiply that number by a set dollar amount that's appropriate for your reputation. I currently use $6 per square inch for oil paintings. Then calculate your cost of canvas and framing, and then double that number.

Step 2: Calculate windows and doors area i.e 20*2+15*2=70 sqaure feet where windows is 15 feet wide and doors are 20 feet. Step 3 Now substract unpainted area i.e 420-70=350 square feet. Step 4: Divide that number by 350 i.e 350/350=1 gallon of paint needed to paint interiors od room.
On both the primary and secondary sides of the art market, prices for artworks are influenced by the broader context of the artist and their position in the art market. Values fluctuate in response to changes in collector demand, general economic conditions, and the artist's stature at the time.
Bidding on a paint job begins with inspecting the site to measure the walls and find any damage or other problem areas. Use the square footage to find the amount of paint and other materials you'll need. Estimate the labor costs of the job and add your overhead and profit margin to the final estimate.
Day rates for a painter and decorator in the UK range from £150 to £400 a day. Not including the cost of paint and materials, daily rates are typically between £100 and £250.
“Painting is just another way of keeping a diary.” – Pablo Picasso. “Life beats down and crushes the soul and art reminds you that you have one.” – Stella Adler.
The general form of the cost function formula is C ( x ) = F + V ( x ) where F is the total fixed costs, V is the variable cost, x is the number of units, and C(x) is the total production cost.
The typical thumb rule is most paints have a spreading rate of 350 square feet per 4 litres of paint (approx 1 gallon), which means that 4 litres of paint will cover 350 square feet. However, this can vary depending on the paint type, its sheen level, and how rough or smooth the surface is that you're painting.
Length x Width x Price per Square Inch
This formula is really common in the art world, but figuring out the right price per square inch can be a bit confusing.
You can calculate a painting charge by starting with the square footage of the area you painted. If you painted one room that's 11x32 feet (132 square feet), charging $5 per square foot would get you $660 in labor costs (132x5).
As a general rule of thumb, you should expect to spend at least $100 on a small, simple painting by an unknown artist. If you're looking for a larger or more complex painting or one by a well-known artist, you should budget at least $1,000.
On average, interior painting contractors charge between $1.50 and $3.50 per square foot. Prices average around $1.50 to $3.50 for walls only and $3 to $4 if you include trims and ceilings. The U.S. national average cost to paint a home interior is $2,003, and the range is between $966 and $3,062.
