Key takeaways
To track your expenses, start by calculating your monthly income and current spending to establish your financial baseline.
Organize expenses into categories and choose a tracking method that fits your lifestyle – whether that's budgeting apps, spreadsheets, or your financial institution's mobile app.
Review your tracked expenses weekly to catch overspending early and monthly to adjust your spending plan.
Use your tracking insights to find opportunities to reduce expenses and put more money toward your financial goals.
Tracking your expenses is one of the most powerful ways to take control of your money – it shows you exactly where your cash goes each month and helps you avoid overspending. Whether you prefer budgeting apps or a simple notebook, expense tracking doesn't have to be complicated.
We'll walk you through practical strategies to monitor your spending, organize your finances, and find opportunities to save.
1. Figure out your current spending
Start by pulling up your recent bank and credit card statements from the last month to track your expenses effectively. Add up everything you spent money on, from rent to coffee. This establishes your spending baseline and shows you where your money is going right now.
Try not to judge your past purchases – you're just gathering information right now. This quick look back often reveals surprising patterns and helps you identify which spending areas need the most attention moving forward.
2. Calculate your monthly income
Before you organize your spending, you need to know how much money is coming in. Add up all your income sources for the month, including regular paychecks, side gigs, and other reliable cash sources.
If your income varies month to month, use an average of your income over the last few months. Knowing your total income creates a clear boundary for your spending and gives you a better idea of how much you have to work with.
3. Review your account statements regularly
Get into the habit of reviewing your account statements every month. A manual review of your statements, whether paper or electronic, allows you to spot fraudulent transactions and see how much you spent.
Gather all your statements, including those from your checking account, savings account, credit card account, and any other types of bank accounts you have.
You may have multiple accounts of the same type – like dedicated savings accounts for big goals or two or more credit cards to help build credit. Every additional account means another place to check when reviewing your statements.
4. Organize your expenses
Now it's time to organize your expenses into categories. You can do this using spreadsheets, a pen and paper, or budgeting apps.
Common categories include:
Rent or mortgage payments
Utilities
Groceries
Transportation
Insurance premiums
Healthcare
Your expense categories should be unique, just as your priorities are. Some people also include an "everything else" category for less common purchases, like clothes, books, or entertainment.
These categories become a monthly expense list, and your expense list becomes an outline for your monthly budget. A budget doesn't restrict how you spend – it gives you a plan for where your money goes. If the word "budget" feels overwhelming, think of it as a "spending plan" instead.
5. Build a budget
Now it's time to lay out your spending plan in a way that's easy for you to follow. Some people use specific categories, such as fast food and dine-in restaurants, while others lump similar costs into a single category.
When building your budget, consider these common methods:
Traditional budget: Break your spending into categories that match your common expenses. Set a spending limit for each category to avoid overspending. Any leftover funds go to savings, and your monthly costs should total less than your income.
Zero-based budget: With a zero-based budget, every dollar gets a "job" – whether that's debt payoff, retirement, emergency savings, or daily expenses. At month's end, every penny is accounted for.
50-30-20 budget: The 50/30/20 rule divides your income into three simple categories. You'll put 50% toward needs, like rent and groceries, 30% toward wants, like dining out and entertainment, and 20% toward savings and debt payoff.
Choose a budget plan you'll stick with. A budgeting plan is most helpful when you use it consistently.
Think about how you interact with your money, and what budgeting habits can get you excited about tracking your savings, paying down debt, and taking control of your spending.
6. Use automation to track expenses
If using pen and paper or an old-school spreadsheet doesn't sound fun, a budgeting app could be a better option.
Budgeting or expense-tracking apps automatically download and categorize your transactions. You can check in frequently to see your monthly spending and whether you have room for additional purchases.
With most budgeting apps, you create categories, set spending limits, and the app handles the rest. You can even set rules to automatically categorize certain transactions, making your tracking system smarter over time.
Tracking your expenses is only half the battle. Analyzing them to help make a financial plan can help you make real financial progress.
Here's how to make the most of your expense tracking:
Weekly check-ins: Spend a few minutes each week reviewing whether you're staying within planned limits or whether your spending is creeping up in certain categories. This keeps your finances top of mind and helps you catch overspending before it becomes a bigger problem.
Monthly deep dives: Each month, celebrate areas where you did well and be honest about where you overspent. Use these insights to adjust your spending plan for the next month.
8. Look for ways to lower your expenses
Now that you're tracking your spending, look for opportunities to reduce your expenses. Every dollar you save can go toward your financial goals – whether that's building savings, paying off debt, or investing for the future.
Look closely at how much you allocate to each budget category and look for ways to cut back. Reducing $50 per month from groceries, $30 from entertainment, and $20 from other categories gives you an extra $100 per month. That adds up to $1,200 per year – more if you stash it in a high-yield savings account or invest it.
9. Try other methods for tracking expenses
If these spending plans don't feel like the right fit, you're not out of luck. While most financial experts recommend budgeting, you can still track your expenses using alternative methods.
For example, you can use the Chime app to check your account balance and recent purchases at any time. If you use your Checking Account for purchases and monthly expenses, your transactions are listed in one place. Opening the app before you buy something helps you decide whether you can afford it.
You can also list fixed and variable expenses so you know what costs to expect each month. Find a way to track where your money goes and avoid overdrafts or shortfalls for expenses you really need.
Start tracking your way to better financial health
Expense tracking puts you in the driver's seat of your finances. Whether you choose budgeting apps, spreadsheets, or simple account reviews, the method that works is the one you'll actually use. Start with your income and current spending, pick a tracking system, and review your numbers regularly to spot opportunities for improvement.
If you're worried about what others may think of your new budgeting habits, push those fears aside. Learn how to become empowered with loud budgeting.
Frequently asked questions about tracking expenses
What's the 50/30/20 spending rule?
The 50/30/20 rule divides your income into three categories: 50% for needs like housing and groceries, 30% for wants like dining out, and 20% for savings and debt payoff.
How often should I review my tracked expenses?
Check your expenses briefly once a week to catch overspending early, then do a deeper monthly review to see the big picture and adjust your plan as needed.
Should I use an app or track expenses manually?
Choose whichever method you'll actually stick with – budgeting apps work great if you want automation, while notebooks or spreadsheets help if you prefer hands-on tracking.
How do I track expenses if I have irregular income?
Focus on covering your baseline expenses first. These are the absolute minimum costs for your essential bills. If you're managing money on irregular income, allocate extra from higher-earning months toward savings or debt payoff.
What should I do if I keep forgetting to track my expenses?
Tie expense tracking to an existing daily habit like pouring your morning coffee, or turn on automatic notifications from your financial app to remind you of balances and recent purchases.
