Variable expenditure refers to the costs that can change from month to month based on usage or consumption. Unlike fixed expenses, which remain constant, variable expenditures can fluctuate significantly. Examples include spending on groceries, entertainment, and utilities, where the amount spent can vary depending on personal choices and circumstances. Managing variable expenditure is essential for effective budgeting. By tracking these costs, individuals can identify patterns and make adjustments to their spending habits. This can help in saving money and ensuring that overall financial goals are met, allowing for better control over one's financial situation.
