Managing your finances effectively begins with a clear understanding of your monthly expenses. Knowing exactly where your money goes each month is crucial for budgeting, saving, and planning for the future. Here’s a simple, step-by-step guide to help you calculate your monthly expenses accurately.

1
Gather Your Financial Statements

Start by collecting all your financial statements, including bank statements, credit card statements, and bills for the last three months. This will provide a comprehensive overview of your spending habits and help ensure you don’t miss any recurring payments or irregular expenses.

2
Categorize Your Expenses

Divide your expenses into fixed and variable categories. Fixed expenses are those that do not change from month to month, such as rent or mortgage payments, car payments, and insurance premiums. Variable expenses, on the other hand, can fluctuate, such as groceries, dining out, entertainment, and utilities.

3
List Every Expense

For a complete picture, list every expense you incur over a typical month. Include everything from the significant payments, like your rent or mortgage, down to the small purchases, like morning coffees or snacks. Nothing is too trivial to note.

4
Calculate Monthly Averages for Variable Expenses

Since variable expenses can change from month to month, calculate the average for each category over the past three months. This will help you account for seasonal variations and ensure that your budget is as realistic as possible.

5
Add It All Up

Once you have listed all your expenses and calculated the averages for your variable costs, add these figures together. The total will give you a clear picture of your total monthly expenditures.

6
Review and Adjust

Look over your calculated expenses. Are there any surprises? Identify areas where you might be able to cut back. Consider setting goals for reducing discretionary spending categories like dining out, shopping, or entertainment.

7
Monitor and Update Regularly

Your expenses can change over time, so it’s important to repeat this process regularly, say every three to six months, or whenever there is a significant change in your financial situation. This will help you stay on top of your spending and make necessary adjustments to your budget.

8
Leverage Technology

Once you have tracked your expenses manually for a couple of months, it’s usually more efficient to switch to an app like Rocket Money. Most budgeting apps are imperfect, so manually doing it can help you build the skills required to ensure the app tracks things correctly.

Conclusion

Calculating your monthly expenses is more than just an exercise in financial management—it’s a crucial step towards achieving financial independence and security. By understanding where your money goes each month, you can make informed decisions about saving, investing, and spending, setting the stage for a healthier financial future. Remember, the more accurate you are in tracking and categorizing your expenses, the more effectively you can manage your finances.
