A budget you check once a month is a report card. A budget you check once a week is a steering wheel.
In Parts 1 and 2 we put savings aside first and gave each discretionary category a weekly target — groceries ~$150/wk, dining ~$58/wk, fun ~$35/wk. The weekly review is where those numbers stop being hypothetical and start doing actual work.
The ritual
Pick a time — Sunday evening, Monday morning, whatever you’ll actually keep — and sit down for five minutes. Compare what you spent in each discretionary category this week against its weekly target from Part 2. Same categories, same time, every week. The ritual is the whole point: one brief, consistent check-in is what separates a budget that guides you from one that just watches.
What you’re looking for
Not perfection. Pace.
Which discretionary categories are running ahead of their weekly number, and by how much? Groceries at $130 on Thursday — that’s fine, you’ve got $20 left and two days of the week. Dining at $72 on Wednesday when your target is $58 — you’re already over for the week, and it’s only the middle of it.
One glance at those three numbers tells you where attention’s needed. You don’t need to analyze anything; you just need to notice which categories are hot.
The one question
End every review with this: Given where I am right now, what do I change for the rest of the month?
That single question is the whole game. Maybe you’re under in groceries and you can relax a little in week four. Maybe dining has run hot two weeks running and something needs to give. The review surfaces the situation; the question forces a decision. And what you do with that decision — how you actually reforecast the rest of the month — is exactly what Part 4 is about.
Part 3 recap
- Review weekly at a set time — consistency turns a check-in into a habit.
- Look at pace vs. targets, then decide one adjustment — the goal is one concrete response to the data, not a complete financial audit.
