Variable expenses are characterized by what feature?

Variable expenses are characterized by their nature of changing from month to month. These expenses fluctuate based on consumption, usage, or activity levels. For example, if you dine out more frequently in one month, your restaurant expenses will be higher, while they could decrease in another month if you choose to eat at home. This variability is a key feature that differentiates them from fixed expenses, which remain consistent regardless of usage, such as rent or mortgage payments.

The other options do not accurately describe variable expenses. Typically, variable expenses can be small or large depending on individual circumstances and spending habits. Additionally, they are not predictable in the same way fixed expenses are, as their amounts can vary significantly each month based on a variety of factors, making it difficult to budget accurately for them.
