Fixed expenditure refers to regular, recurring expenses that do not change in amount over time. These costs are predictable and typically include items such as rent, mortgages, insurance premiums, and subscription services. Because they remain constant, individuals and businesses can easily budget for these expenses each month. Unlike variable expenses, which can fluctuate based on usage or consumption, fixed expenditures provide a stable financial foundation. Understanding fixed expenditure is essential for effective financial planning, as it helps individuals and organizations allocate resources and manage cash flow more efficiently.
