Guides to household money

Straight answers about running money in a household, including where the popular advice falls apart. Written to be useful whether or not you ever install this app.

• Why budgeting apps end up unopened after three weeks

  Almost everyone who quits a budgeting app blames their own discipline. The real causes are structural, and most of them are fixable in the first ten minutes of setup.

• How to share a budget with your partner without it becoming surveillance

  Joint tracking fails for social reasons far more often than technical ones. What to agree before you start, what to keep out of the shared book, and how to run the monthly conversation so it stays about numbers.

• How to split shared household expenses when you earn different amounts

  Fifty-fifty, proportional to income, or one pot: each rule is fair by a different definition and each breaks somewhere. How the three compare, and what to do about unpaid work, debt and savings.

• Does the 50/30/20 rule actually work for a family?

  Where the rule came from, why the "50% on needs" half is the part that breaks first, and what to do when housing alone eats most of your income.

• How to set a grocery budget that survives contact with a supermarket

  Food is the category most households want to control and the one where guessed budgets fail fastest. How to derive a number from your own spending, why the first figure is usually too low, and which tactics actually move it.

• Is it safe to put your spending in a budgeting app?

  Your ledger is a detailed record of where you go and what you do. What the different kinds of budgeting app actually hold, the questions worth asking before you commit, and honest answers for this one.

• How to record cash spending without inventing the numbers

  Cash is where a household ledger quietly goes wrong: no statement, no notification, and the purchases you lose are the small frequent ones you wanted to see. Four approaches, honestly compared.

• How to budget for the expenses that only happen once a year

  The insurance premium, the school fees, the car service, the trip home. A monthly budget that ignores them is slightly wrong every month and catastrophically wrong in one, and the fix is arithmetic rather than willpower.

• How to get your data out of a budgeting app

  Export is the difference between a service and a trap. What a real export contains, what to test before you commit years of entries, and the specific ways a CSV gets corrupted on the way between two apps.

• How to handle children’s pocket money in the household ledger

  Not the parenting question — the recording one. Allowance, payment for chores and reimbursement-on-demand each do something different to your numbers, and the third one is the one that surprises people.

• Why setting a budget is much harder than tracking spending

  Recording is a description of the past; a budget is a prediction plus a commitment. Those are different jobs, and both of them fail for reasons that have nothing to do with discipline.

• How much money transparency does a household actually need?

  Total visibility of every transaction is not the maximum of trust — it is a particular arrangement with a particular failure mode. What has to be transparent regardless, and what is better left undivided.

• Does paying by card actually make you spend more?

  The honest version of a very popular claim: what the famous experiment found, why later work is much more mixed, and the one asymmetry between cash and card that holds regardless of the effect size.

• How to track spending on a trip without ruining the trip

  Multiple currencies, one person paying for everybody, cash again, and no appetite for admin. How to structure a holiday in your ledger so that one week does not destroy the readability of the month around it.

• How to categorise a shopping trip that was half food and half everything else

  One till receipt with vegetables, dish soap and a birthday card on it. Splitting it three ways is accurate and unsustainable; booking it all as groceries is fast and quietly wrong. Here is how to decide which error you can live with.

• How to record refunds, returns and money someone paid you back

  Money that comes back is the most commonly mishandled thing in a household ledger. Booked as income it distorts what you earn; ignored it distorts what you spend. Here is where each one actually belongs.

• How to restart a budget after you stopped recording for two months

  The gap is not the problem. The instinct to fill it in from memory is. What to do with the missing weeks, why starting over from zero beats reconstructing, and how to make the second attempt cheaper than the first.

• How to track money you lend to friends and family without it feeling like debt collection

  Money lent between people who like each other is rarely forgotten on purpose — it is forgotten because nobody wrote it down. A record that is precise about amounts and quiet about pressure.

• Should you record spending daily, weekly, or as it happens?

  Three cadences, and the fact that decides between them: how fast the memory of a small purchase decays. What each one costs, what each one loses, and which failures are recoverable.

• How to budget when your income is different every month

  Advice built for a fixed salary breaks immediately on freelance, commission or shift work. Budget against your outgoings and your worst months rather than against an average you will not receive.

• Tracking, budgeting and reconciling are three different jobs

  Most households try to do all three in the same sitting and end up doing none of them properly. What each job actually answers, why they interfere with each other, and an order that survives a busy month.

• Who should actually do the recording in a household

  One person doing all the entries is the most common arrangement and the one that quietly turns a ledger into an audit. The four arrangements that exist, what each requires, and the role trap that ends most of them.

• Joint account or separate accounts: which is less work to keep track of

  The choice is usually discussed as a question about trust. Treated instead as a question about plumbing, it has clearer answers: each structure loses different transactions, and one of them loses almost none.

• How to merge two separate ledgers into one without double counting

  Two people have been keeping their own records for months and now want a single household book. What to do about the overlap, how to remove the transactions that exist twice, and whether to bring the history across at all.

• Should you go back and fill in the expenses you forgot to record

  A fortnight of missing entries is uncomfortable to look at. Reconstructed data is not neutral, though — it is wrong in a predictable direction, and knowing which direction tells you when backfilling is worth doing.

• How to record one payment that was split across several methods

  Part on a gift card, part contactless, a voucher on top and the rest in cash. How many entries that actually is depends on which question you want the record to answer, and one of the two answers is much less work.

• How to record money spent supporting elderly parents

  Regular transfers, things you pay for directly, costs shared with siblings, and the question of whether any of it is really an expense. A structure that answers the practical questions without turning care into an audit.

• How to hold a monthly money conversation that does not turn into a trial

  Most households either never talk about money or talk about it only when something has gone wrong. A short, scheduled, deliberately narrow conversation avoids both, and the structure matters more than the goodwill.

• Why your ledger never matches your bank balance, and when to care

  A household record and a bank balance answer different questions, so a gap between them is normal rather than a mistake. The four kinds of difference, which two are worth investigating, and a ten-minute monthly check.

• How to record shared subscriptions and family plans

  One card pays, several people use, some of them do not live with you, and half of it renews annually. How to record subscriptions so that the yearly total is real and the forgotten ones become visible.

• Budgeting for the first year with a baby, when nothing arrives on a monthly rhythm

  The first year does not cost a smooth amount every month. It has a shape: a front-loaded burst of purchases, a low steady drip of consumables, unpredictable medical costs, and an income that usually steps down partway through.

• Should you record every small expense, or is that a waste of your evening?

  Small purchases are where most people either give up or find the thing they were looking for. A way of deciding which of the two you are in, without a rule that applies to every household.

• Splitting expenses when one of you has no income coming in

  Parental leave, redundancy, caring for a relative, a career break. What changes when the household has one income, and how to arrange the money so that nobody ends up feeling they are spending someone else’s.

• How to record family medical costs so the year makes sense afterwards

  Medical spending is the category most worth annotating: money goes out, some of it comes back months later, and the entry that means nothing today decides whether a claim is provable in March.

• How to record what school and lessons actually cost across a year

  Education money arrives in three shapes at once: large payments a few times a year, small constant ones, and the driving. Recorded badly, the yearly total is invisible until you go looking for it.

• Keeping one household ledger when you are living in two places

  Long-distance commuting, a job in another city, a child at university abroad. One household paying rent and bills in two places needs a book that shows both, and a rule for what counts as household spending.

• A boiler, a washing machine, a new phone: where does a large one-off purchase go?

  Record it in the month you bought it and that month looks catastrophic. Spread it across a year and your ledger stops matching your bank. Both are defensible; each misleads you about something different.

• How to work out what moving house actually cost you

  Moving is a short, expensive project spread across two or three months and a dozen categories. Framed as ordinary monthly spending it is unreadable; framed as a project it produces a number worth having.

• When you and your partner disagree about spending, the ledger is not a referee

  Most money arguments are not about the numbers, and producing the numbers rarely settles them. What a shared record can genuinely do, what it cannot, and how to stop it being used as evidence.

• 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.
