Fixed expenses are costs that remain the same month after month, such as rent, mortgage payments, and car loans. These expenses are predictable and stable, allowing for easier budget planning. Fixed expenses are essential to account for in any budget because they must be paid regularly and are usually non-negotiable.

Unlike variable expenses, such as groceries and entertainment, fixed expenses do not fluctuate based on consumption. Managing fixed expenses effectively is key to ensuring financial stability. Budgeting around fixed costs helps maintain consistency, even when income varies.
