You cannot plan your money well until you know where it really goes. In this lesson you find out, using your own statements, a few simple categories and a short weekly check. No guessing needed.

Memory is a poor guide

Most of us think we know what we spend. But memory is a poor guide. In one small study, people underestimated their card spending by about 30 percent, but their cash spending by only about 7 percent.

Card payments are easy to forget because no money visibly leaves your hand. That is why the first step is to look at what actually happened.

Two pairs of bars. For Card, the remembered bar is much shorter than the real bar, labelled About 30% missed. For Cash, the two bars are close, labelled About 7%. A faded card is marked Easy to forget.(opens the full-size picture)
Card spending is the easiest to forget.

Start with your statements

So start with what has already happened. Go back through one or two months of your bank and card statements, and note your cash spending too. If you pay with cash, jot down what you remember, or keep a small note for the next few weeks.

That gives you a real starting point, with no guessing.

Two bank statements, Month 1 and Month 2, with lines for rent, groceries and fun. Next to them a wallet with a banknote and a notepad titled Cash listing bus $4 and lunch $9. Labels read One or two months, Cash counts too and Real starting point.(opens the full-size picture)
Statements for one or two months, plus your cash, give a real starting point.

Five or six categories

Next, sort every line into five or six categories. For example: home, food, transport, health, fun and other. Keep it simple.

Too many categories turn tracking into a chore, and a chore does not last. A few broad jars are enough to show you where the money goes.

Six jars labelled Home, Food, Transport, Health, Fun and Other, each part full. Below, a crossed-out grid of twenty tiny jars with the labels Too many and A chore.(opens the full-size picture)
Six jars are easy to keep. Twenty are a chore.

Why checking works

Checking your progress helps. In a review of more than a hundred studies, mostly about health goals, people who monitored their progress were more likely to reach their goals. It worked better when they wrote the results down.

Those studies were not about money, so treat the finding as a good sign rather than a promise. But it fits common sense: what you look at, you can change.

A checklist on a clipboard labelled Monitor, a target with an arrow near the centre labelled Reach goals, and a notepad titled Week 1 with a pencil listing Food $85 and Fun $40, labelled Write it down. A tag says 100+ studies, and a note says Writing it down worked better.(opens the full-size picture)
Monitoring helps, and writing it down helps more.

Look without judgment

Do it without judgment. You are measuring, not grading yourself. That matters, because people tend to look less when money is tight. In one country’s money app data, people logged in less often once they were overdrawn, just when looking would help most.

If a number surprises you, that is useful information, not a verdict on you. A ruler does not tell you off.

A ruler labelled Measuring with a tick, and a big red letter F labelled Not grading. On the right a phone showing a balance of minus $50 beside a closed eye, labelled Logged in less, just when looking helps most.(opens the full-size picture)
Measure, don't grade, and keep looking when it is hard.

If looking feels heavy

Money worry is common and it can make us avoid our accounts. If it is wearing you down, the guide on money anxiety can help. If you are struggling to pay bills, contact your country’s free money advice service early.

A weekly check

Pick a fixed time each week, say Sunday evening, and look at your totals, whatever the balance. Ten minutes is enough. Then change one thing, and look again next week.

One small change a week is easier to keep than a big reset, and each check shows you whether the change worked.

A week calendar with the Sunday column ticked on every row, labelled Sunday evening: money check. A timer showing 10:00 is labelled Ten minutes is enough. A card says Change one thing, with a dashed arrow back to the calendar and the note Look again next week.(opens the full-size picture)
Same time each week, ten minutes, one change.

Welcome back. In this lesson, you'll find out where your money really goes, using your own statements, a few simple categories, and a short weekly check.

So remember: start from real statements, not memory. Use five or six simple categories. And check at a fixed time each week, without judgment. Before the next lesson, sort last month's statement into five or six categories. Next, you'll try your first budget method: the fifty thirty twenty rule.
