How to track money you lend to friends and family
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.
You covered your brother’s share of a family present in March. A friend borrowed two hundred for a deposit in May and mentioned it once since. Somebody at work has owed you for lunch since a Thursday you can no longer date. None of these people are dishonest. All of them have forgotten, and so, roughly, have you — which is the actual mechanism by which lending between people who like each other goes wrong.
The awkwardness people feel about tracking this is really an anxiety about becoming the sort of person who keeps accounts on their friends. That anxiety is reasonable, and it is also solvable, because the discomfort comes almost entirely from what a record is used for rather than from the record itself.
A loan is not an expense, and treating it as one breaks two things
When money goes out, the reflex is to record spending. But lending is not consumption — the money has changed location, not disappeared, and there is a claim attached to it. Booking it as an expense overstates what your household spent that month, sometimes dramatically if the amount was large, and it also means that when the money comes back you have nothing to reverse, so you record it as income and overstate that too.
The effect on your own numbers is the boring half. The interesting half is that an expense entry has no memory of who owes what. A month later you have a line saying money left; you do not have a line saying somebody has it. Almost every forgotten loan between friends is forgotten at exactly this step, not because anyone decided to let it go.
The fix is to give the amount its own line rather than burying it in a category. Whether your ledger has a formal transfer type or you use a dedicated category for it, the requirement is the same: the entry has to survive being looked at three months later and still answer who, how much, and when. A name and a date in the note field does that job.
Record generously, chase rarely
The distinction that makes this comfortable is between having a record and using it. A written record does not obligate you to act on it. It simply means that if the question ever comes up — and it usually comes up sideways, in a conversation months later — you are answering from a note rather than from a feeling.
That difference is worth more than it sounds, because the alternative is not "no record" but "a vague one". Vague memory of being owed is corrosive in a way a written figure is not. It shows up as a low-grade sense that things are uneven, it cannot be checked, and it tends to grow in the telling. A specific number with a date attached is smaller and more manageable than the feeling it replaces, and it also cuts the other way: quite often the note reveals you were paid back and had forgotten.
For small amounts between close friends, the honest policy is often to record it and never mention it. The record is there so that you know, not so that anyone is pursued. This is also why the note matters more than the category: what you want later is the fact, not a running total labelled as debt.
Decide when it stops being a loan
Some of this money is not coming back, and the useful thing is to decide that on purpose rather than let it hang. A loan that has been outstanding long enough that you would never actually raise it has already become a gift; the only question is whether your ledger knows that yet.
Marking it as a gift does two concrete things. It gets the amount out of the mental column labelled "owed to me", which is where the low-grade resentment lives, and it puts the cost where it belongs in your own history, so a year of records shows what your household actually gave away rather than carrying a claim nobody intends to make. Where it lands is a judgement call — many households book it under gifts or family support — but the important part is that a decision was made and written down.
The same logic applies to lending within a household, where the situation is different again. If two people share a book and one covers something for the other, that is usually not a loan at all — it is the household spending money, and the interesting question is how the couple splits things overall rather than who fronted a particular payment. Fambook records who made each entry so the totals stay true and each person can see their own share, which is a different job from keeping a running balance between two people. If you find yourself wanting a formal IOU with someone you live with, that is usually a signal about how the household divides things, not a request for better bookkeeping.
The aim is not to run a credit department for your friends. It is to make sure that if a friendship ever hits a rough patch, it is not because of two hundred pounds that both of you half remember.
Frequently asked questions
Should I record money I lend as an expense?
No. The money has moved rather than been consumed, and there is a claim attached to it. Recording it as an expense overstates your spending for that month and leaves you nothing to reverse when the money comes back, at which point you are likely to overstate your income too.
Is it petty to write down what a friend owes me?
The discomfort is about what a record is used for, not about its existence. A note in a ledger obliges nobody. The realistic alternative is not "no record" but a vague sense of being owed, which is harder to check, less specific, and considerably more corrosive than a number with a date next to it.
What should I write down when I lend money?
The amount, the date, and the person’s name in the note. That is enough to answer the only question you will have later. Anything more elaborate is bookkeeping you will not maintain, and anything less will not survive three months.
When should I write off a loan?
When you know you would never actually raise it. At that point it has already become a gift in practice, and recording it as one gets it out of the mental column marked "owed" and puts the cost honestly into your own history.
How does this work when the two of us share a household budget?
Inside a household it is usually not a loan at all — the household spent money, and the useful question is how the two of you split things overall rather than who happened to pay. A shared book that records who made each entry answers that without anyone keeping a running balance against the other.
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.
