How to review a whole year of household spending without ruining Christmas
An annual review is worth an evening and not more. Which quantities repay attention, which comparisons are meaningless in a household of this size, and how to stop it becoming a verdict on the year.
Somewhere between Christmas and the middle of January, a lot of households sit down with a year of records and try to work out how it went. It is a good instinct and the execution usually goes wrong in the same two ways: the evening turns into a verdict on the people involved rather than a look at the year, and the comparison everybody reaches for first — this year against last year — turns out to measure almost nothing.
A yearly review is worth doing and it is worth about an evening. What follows is what tends to repay the time, and what tends to waste it.
Why year-on-year comparison is usually meaningless
The comparison feels like the natural thing to do and it rests on an assumption that is almost never true for a household: that the two years are comparable. In a business, most of the structure stays put from one year to the next. In a household of two to five people, a single event moves everything.
A child starting or leaving nursery. Someone changing jobs, or the commute changing length. A move. A year with a boiler in it and a year without. A relative becoming ill. One person going down to four days. Any one of these swamps every behavioural change you could possibly have made, and most years contain at least one of them.
So a total that rose fifteen percent is not evidence that the household became careless, and a total that fell is not evidence of virtue. Before you compare anything, write down the four or five things that were structurally different about this year. If that list is not short, the comparison is not measuring behaviour, and continuing to read it as though it were is how a review becomes an argument.
What is worth comparing across years is narrower: a single category whose circumstances did not change, and the share of income going to costs you cannot alter within a month. Those two survive the noise reasonably well. Totals do not.
The four things worth looking at
A review with four questions in it finishes in an evening. A review that tries to look at everything finishes in resentment.
One: the shape of the year, not the total
Look at the monthly figures in sequence and find the peaks. Almost every household has three or four months a year that are much heavier than the rest, and they are usually predictable in advance: the month school starts, the month of the annual insurance renewal, December, the month of a family birthday cluster. Knowing which months those are is more useful for next year than any single number, because it is the only thing that lets you see a difficult month coming.
Two: the fixed obligations
Add up everything you could not change within a month if you needed to — housing, insurance, childcare, subscriptions, loan payments, the standing commitments — and look at it as a share of what came in. This one number does more work than any category breakdown, because it tells you how much room the household has. It also catches the drift that nothing else catches: fixed costs rise quietly, one small subscription and one renewal at a time, and nobody notices until the year in which everything feels tight for no obvious reason.
Three: the categories that surprised you
Not the largest ones. The largest categories in a household are housing and food, every year, in every household, and confirming it again is not information. What is worth attention is any category that is a different size from what you would have guessed. Surprise is the only real signal in a review, and it points at the places where your sense of your own life has drifted away from what is happening.
Four: the one-off purchases, gathered up
The appliance, the repair, the emergency, the replacement. Individually each felt like an exception. Collected into one line for the year, they are a normal and fairly stable feature of running a household, and the total is the best guide you will get to how much slack next year needs.
What to skip
- Averages of anything lumpy. A monthly average of a category that happens three times a year describes no month that ever existed.
- Comparisons with other households or with published averages. You do not know what is in their number, and regional variation within a single country is usually larger than the difference you are worrying about.
- Categories that are small and fixed. There is nothing to find, and going through them is what makes the evening feel like an audit.
- Any month you know is incomplete. A year with a six-week gap in the summer is still worth reviewing — just read the gap as a gap rather than as a quiet season.
- The impulse to explain every entry. You will not remember, and the ones worth remembering are the ones you wrote a note on at the time.
How to run the evening so it stays civil
The structure matters more than the analysis, particularly if two people are doing it together. Look backwards briefly and forwards mostly.
- Say the four numbers out loud with no commentary attached. Nothing derails a review faster than an explanation arriving before a figure has finished being heard.
- Each person names one thing that surprised them. Not one thing that annoyed them about the other person — one thing that surprised them.
- Write down the structural facts of the year: what changed, what was unusual, what will not repeat. This is what makes the year readable to you in three years time, and it takes five minutes now and is impossible later.
- Pick one change for the coming year. One. Reviews that produce six resolutions produce none, and the household that changed one large fixed cost has done more than the household that resolved to be careful.
- Note the known dates in the coming year — the renewals, the term payments, the trip already booked — so the heavy months are on a list rather than in somebody memory.
- Stop, on time, at a point you agreed in advance.
Ending on time is not a stylistic preference. The reason annual reviews acquire a reputation is that they run long, drift from the numbers into a general assessment of how the household is doing, and end somewhere nobody intended. A review with a stated end is one you will be willing to do again next year, and doing it again is where most of the value is: the second year of records is worth considerably more than the first, and the fifth is worth more than that.
What a year of records is actually for
Not judgement, and not a score. Its real function is to let you answer questions later that you cannot answer now, and you do not yet know which ones. Whether the arrangement you are considering is affordable. What the last move cost. Whether the thing you have started to resent paying for is actually large. How long appliances last in your house. When the fixed costs started climbing.
Those are all questions from the future, and the only thing that answers them is having written things down while they were happening, imperfectly, with gaps in the summer. The review is where you find out what you now have, and it is a reasonable evening to give it once a year.
Frequently asked questions
Is comparing this year to last year useful?
Rarely for totals, because a single life event — a child starting nursery, a job change, a move, a boiler — swamps any behavioural change. Write down what was structurally different before comparing anything. Individual categories whose circumstances did not change, and the share of income going to fixed costs, survive the comparison better.
What should I actually look at in an annual review?
Four things: the shape of the year month by month so you can see which months are heavy, the share of income going to costs you cannot change within a month, any category that surprised you, and all the one-off purchases gathered into a single line. That is an evening, and it is enough.
How long should a yearly money review take?
About an evening, with an end time agreed in advance. Reviews that run long drift from the numbers into a general assessment of how the household is doing, which is what gives them their reputation and what stops people doing one the following year.
What if my records have gaps in them?
Review it anyway and read the gaps as gaps rather than as quiet months. A year with a six-week hole in it still answers most of the questions worth asking, and reconstructing the hole from memory would make the rest less trustworthy rather than more.
How many things should we change after a review?
One. Reviews producing six resolutions produce none in practice, and one change to a large fixed cost is worth more than a year of general carefulness about small purchases. Pick the one, write it down, and leave the rest.
Try it for one month
Fambook gives a household one shared ledger: anyone can add an entry in seconds, every entry says who spent it, and the month adds up in one place instead of two. Records with no signal and syncs afterwards. Recording, categories, budgets, statistics, CSV import and export, sync and sharing for two people are free — the subscription only buys you less typing.
