Track your spending by reviewing every transaction — bank statements, credit card statements, and cash — and categorizing it weekly or monthly. Most people discover their actual spending differs significantly from what they assumed, which is exactly why tracking is the first step in any budget or savings plan.
Tracking spending means knowing where every dollar went — not estimating it. The CFPB's budgeting guidance identifies spending tracking as the prerequisite to any meaningful budget: without accurate data, you're planning based on assumptions that are almost always wrong. Most people underestimate their spending in 2–3 categories when they guess vs. when they actually count.
Pull your last two to three months of bank and credit card statements. Open a spreadsheet or use the CFPB worksheet. Go line by line and assign each transaction a category: housing, groceries, dining, transportation, subscriptions, utilities, medical, entertainment, debt payments, other. Sum each category. This takes 30–60 minutes the first time and reveals your true spending pattern. The FTC recommends doing this exercise before building any budget — the data is more reliable than memory.
Once you know your baseline, shift to weekly reviews: every Sunday (or any consistent day), scan your transactions from the past week and categorize them. This keeps the data current and makes you aware of spending in real time rather than retroactively. Most banks let you add transaction notes or tags in their mobile app — use that feature so categorization is faster each week.
Once you have two to three months of actual spending data, compare it to your income. If spending exceeds income, you have a gap to close — see the CFPB's debt and budget tools for next steps. If there's a surplus, assign it: emergency fund, debt payoff, or a savings goal. Unassigned surplus tends to disappear into discretionary spending without intention behind it.
