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.
(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.
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.

Professional house painters typically charge an average of $3 to $6 per square foot, $20 to $50 per hour, or $200 to $500 per day. The average cost to paint a 10-foot by 12-foot bedroom is $391 for just the walls or $815 for a full paint job that includes ceiling, walls, baseboards, and trim.
Formula of Paint Calculator
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.

Simply divide the surface area by the coverage to get the number of gallons you'll need. For example, if you're painting a 10x10 room with a coverage of 200 square feet per gallon, you'll need 0.5 gallons of paint (10x10/200 = 0.5).
To calculate the painting area for the cost of painting a house, measure the total surface area of walls, ceilings, or trims to be painted. Multiply the length and height of each wall and add them up to get the total area, then estimate the paint required.
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.
To calculate the price-per-square-inch of a work of art is simple: you multiply the length of the piece by its width to get the number of square inches, and then you divide the price of the piece by the number of square inches. (You can also use united inches instead of square inches.)
FORMULA 1: Square Inch × Dollar Amount
To get the square inches of a painting, multiply the width of the work by the length. Next, multiply this number by a dollar amount that makes sense for your reputation and credentials. Then round to the nearest hundred.
You might pay R60 to R200+ per square metre. This depends on paint quality and prep work needed. A standard room typically costs between R1,000 and R6,000 to paint. Labour costs usually range from R450 to R900 per hour.
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.
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.
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.
What do most painters charge per hour? you can expect to pay anywhere from $20 to $50 per hour for a professional paint job. The more experienced and skilled your painter, the higher their hourly rate will be–and there's no denying that more complex projects take longer to complete.
