Which of the following is true about variable expenses?

• A. Variable expenses stay exactly the same every month.
• B. Variable expenses involve fixed payments.
• C. Variable expenses can fluctuate month to month.
• D. Variable expenses are not controllable.

Answer: (C)

Variable expenses are costs that change based on how much you use or buy, so they can go up or down each month. This is what makes them fluctuate from one month to the next. For example, your electricity bill can rise in a hot month if you run the AC a lot, or groceries can vary with what you buy and how often you eat out. In budgeting, this distinction matters because fixed expenses stay the same every month (like rent or a loan payment), while variable ones do not. You can influence variable expenses by changing habits or usage—seeking energy efficiency, meal planning, or cutting back on nonessential purchases. The other statements don’t fit because fixed payments stay constant, and many variable expenses are controllable to some extent.
