This tool will help you estimate the amount of paint you need for your project.

## How to Use the Paint Job Estimation Calculator

This calculator estimates the amount of paint needed and the overall cost for a paint job based on several parameters.

### Instructions

- Enter the length of the wall in feet.
- Enter the height of the wall in feet.
- Enter the number of windows and doors present in the wall. This will be used to subtract from the total area as they do not need painting.
- Enter the number of coats of paint you plan to apply.
- Enter the coverage area per gallon of paint. This information can usually be found on the paint can.
- Enter the cost per gallon of paint in USD.
- Click the “Calculate” button to get the results.

### Calculation Explanation

The calculator works by first calculating the total area of the wall by multiplying the length and height. It then subtracts the total area taken up by the windows and doors. The resultant area is then multiplied by the number of coats and divided by the coverage area per gallon to get the total gallons of paint needed. Finally, it multiplies the total gallons by the cost per gallon to get the total cost.

### Limitations

Please note that this calculator provides an estimation. Exact values might differ based on the actual size and shape of the wall, the exact dimensions of windows and doors, and other factors such as paint waste or coverage efficiency. Always consider buying slightly more paint than estimated to account for such variables.
