Utility bills can fall into which category of expenses?

Utility bills are categorized as variable expenses because their amounts can fluctuate month to month based on usage. Unlike fixed expenses, which remain constant, like rent or insurance premiums, utility bills can vary significantly depending on factors such as weather, energy habits, and changes in service rates.

While fixed expenses are predictable and remain stable over time, variable expenses can change and often require regular monitoring to manage effectively within a budget. Periodic expenses occur occasionally rather than on a consistent monthly basis, and discretionary expenses are non-essential costs that can be adjusted or eliminated based on lifestyle choices.
