What is Fixed Expenses?

Fixed expenses are the same every month—rent, mortgage, car payments, insurance premiums. They don’t change with your spending. Examples include rent or mortgage payments, auto loan installments, insurance premiums, and fixed subscription services. According to CFPB budgeting guidelines, fixed expenses are the first category that must be accounted for in a cash flow plan because they represent non-negotiable legal or basic survival commitments.

While fixed expenses provide predictability, they can also restrict budget flexibility. In the event of an income reduction, fixed expenses cannot be easily adjusted in the short term, highlighting the importance of maintaining an emergency fund to cover these commitments.
