A monthly expense list is a list of all recurring and irregular expenses for a person or business each month. For many people, not including less frequent expenses into a monthly expense list is a primary reason for failure to stay within a set budget.
To generate an accurate monthly expense list, a person needs all bank and financial statements depicting expenses. Regular or recurring expenses include rent or mortgage payments, car insurance, and utilities that are paid each month. Pet grooming, home maintenance and hobby supplies are among the irregular expenses that are hard to incorporate on a monthly basis.
