👉 Expense math involves calculating the total cost of goods or services you incur in a given period, typically a month, by adding up all individual expenses. This process starts with identifying all your expenses, whether they are fixed (like rent or salaries) or variable (such as groceries or entertainment). For each expense, you multiply the amount spent by the quantity consumed or used. After gathering all these figures, you sum them up to get the total monthly expense. This method provides a clear picture of your spending habits, helping you budget effectively and identify areas where you might be able to cut costs. It's important to maintain accurate records of your expenses to ensure the math is precise and useful for financial planning.
