To draw a circle or pie graph for budgeting purposes, calculate the percentage of the budget for each category. Then multiply the percentage (in decimal form) by 360 degrees. This is the number of degrees in the circle that should be allotted for the category.

Calculate the number of degrees in a pie graph that would be needed for the Rent category that has a percentage of 20%.

The number of Degrees needed for 20% budget = (20%)*(360) = 72 degrees.
