# Room Painting Cost Calculator

The estimated cost of painting the room is: \$0.00

Painting a room can give it a fresh and vibrant look, but it’s important to budget for the cost of paint and supplies. To make this process easier, we’ve created the Room Painting Cost Calculator. This handy tool allows you to estimate the cost of painting a room based on its dimensions and the cost of paint per gallon.

### Formula

To calculate the estimated cost of painting a room, we use the following formula:

1. Calculate the total wall area to be painted by summing up the areas of all the walls.
2. Determine the number of gallons of paint needed by dividing the wall area by the coverage of one gallon of paint (usually around 350 square feet per gallon).
3. Multiply the number of gallons needed by the cost of paint per gallon to get the total cost.

### How to Use

1. Enter the length, width, and height of the room in feet.
2. Input the cost of paint per gallon in dollars.
3. Click the “Calculate” button to get the estimated cost of painting the room.

### Example

Suppose you have a room with dimensions:

• Length: 12 feet
• Width: 10 feet
• Height: 8 feet

And the cost of paint per gallon is \$25. Using the Room Painting Cost Calculator, you would find that the estimated cost to paint this room is \$228.57.
