Your partner does not contribute to shared expenses: how to talk about it and how to work out the numbers

It is not that there is no money. It is that the groceries, the electricity and five hundred small things are paid by one person, the other never sees them, and the conversation has been waiting months for the right moment.

You do the weekly shop. The electricity and the internet come off your card, because the contracts are in your name. Cleaning products, medicines, a present for your partner's parents, a hundred small things nobody counts. Your partner pays for themselves: their coffee, their clothes, their nights out. You have lived together for a year and your partner does not contribute to shared expenses, even though there is no shortage of money for their own.

This is one of the most common arguments about money in a relationship, and one of the least often spoken out loud. The amount is rarely large over a month; what is large is what sits behind it. Saying “you do not contribute to our life together” sounds like an accusation about far more than money, so it gets said in anger, or not at all.

This piece is about organisation, not about the law, and not about whether the relationship makes sense. There is not a word here about marriage, joint assets or who is entitled to what: those are different conversations, with different people. What there is instead is what two people who will sit down to dinner together again tomorrow can actually do: how to raise it without it turning into a row, and how to replace a feeling with a number you both see the same way.

Why this is harder in a relationship than with anyone else

With a flatmate, a conversation about an unpaid bill is awkward, but it has something to stand on: there is an agreement, there are several people, there is rent with a due date. In a couple there is none of that, and that is exactly why the subject grows for months.

Expenses are invisible to the person who does not pay them. The shopping disappears into the fridge, the electricity leaves the account automatically, the toilet paper is simply there. The person who does not pay for it sees none of those transfers and may honestly have no idea what it all costs. You see every one.

There is no settling-up day. With flatmates, a bill gets settled when it arrives. In a couple there is no moment at which anyone is late, because nobody ever agreed that anything was owed. A debt with no due date is not a debt, it is simply your expense.

The conversation sounds like an accusation. In a relationship, you do not contribute means more than you do not owe me 200 €. It means you do not treat this as ours. That is why it gets avoided, and why, when it finally erupts, it is no longer about money.

Each of you remembers a different number. You remember the 380 € of groceries and the 90 € electricity bill. Your partner remembers paying for the car you both drive and for last year's holiday. You are both right, and without a shared record the conversation starts with an argument about facts, which is the worst possible place to begin.

Before you say anything: three things to check

A quarter of an hour here saves weeks of counting in silence.

Is your number solid? Not I pay for everything, but one month, written out: groceries, bills, small things. A card statement is enough. A figure given from a feeling will be challenged, and rightly so, because after six months a feeling is always bigger than the sum.

Does your partner even know? This happens more often than you would think. If one person pays for the groceries and the other for the car loan and the insurance, one head may hold a draw that the other head does not. Write out both sides, not only yours.

Is this really about money? If something else has been building up for months, the housework, the time, the attention, the amount will only be a pretext and the conversation will go there anyway. In that case it is more honest to separate the two and start with the one that matters more.

How to talk about money in a relationship without it becoming a row

Three elements, and each one does something specific.

Pick a moment when nothing is happening. Not at the till, not right after your partner has bought something, not on the day the bill arrived. An evening with no plans, with a warning: I want to talk about how we split expenses, not about any particular situation.

Talk about the arrangement, not about blame. You do not contribute has a subject and a culprit. Our shared expenses come to 640 € a month and right now I pay them, I would like us to agree how we split that has a number and a proposal. The second can be accepted without losing face; the first cannot.

Bring the figure written out, and a proposal. The total for one month, broken into a few lines, and one concrete proposal for the future: equally, in proportion, or each taking different bills. A conversation that ends with an arrangement does not come back. A conversation that ends with well, try harder comes back in three weeks.

Your partner does not contribute to the bills: when it comes back every month

A one-off expense that somebody has not paid back, and expenses that the same person pays every month, are two different things, and confusing them is the most common mistake.

A loan is closed with one conversation. A shared life has no end: there will be groceries next week and in five years. Reminding every time is unsustainable, because after the third time one person becomes the one who nags and the other the one who is nagged, and there is no way out of those roles in a relationship. With a flatmate, the same situation has a simpler way out, because there is an agreement and there is an end to living together. In a couple, the way out has to be an arrangement.

Three things that actually close the subject, and none of them relies on reminders.

A split agreed once. Equally, in proportion to income, or a joint account that everything shared comes out of. Which split to choose and what each one means when one of you earns more, we covered in our piece on how to split expenses as a couple. What matters here is one thing: a split agreed calmly is an arrangement, the same split produced in an argument sounds like a reproach.

Split at source. One person takes the electricity and the internet, the other the groceries, or each of you pays your share into a joint account on the first of the month. An expense that is split at the moment of paying does not have to be settled later, and nobody has to bring it up.

A fixed day when you both look at the number. Once a month, five minutes, the shared balance on the table. Not so that anyone has to explain themselves, but so that a debt cannot grow to the size at which the conversation stops being possible.

What not to do

Four reflexes that seem sensible and all cost more than they give.

Counting in silence. Keeping a tally in your head for six months and presenting it in full on the day you have had enough. The amount is enormous by then, so is the anger, and the other person hears about the problem for the first time and hears it as a verdict.

Punishing with the wallet. Stopping the shopping so the other person feels the difference. Empty shelves teach nothing except that the home has become a battlefield, and that costs more than all the groceries put together.

Comparing yourselves with other couples. At Kate and Mark's, he pays for everything. Other couples have different incomes, different arrangements and different troubles you cannot see. The only split that counts is the one the two of you agreed to.

Piling on other issues. If the unhoovered flat and the in-laws turn up in the same conversation, the money stops existing as a subject. One conversation, one issue, one number.

One number instead of a feeling

Every sentence in this piece repairs a gap that opened much earlier: nobody was keeping a shared record, you included. The feeling that I pay for everything is either true or not, but as long as it is a feeling, it can neither be proved, nor challenged, nor put right.

When the record is kept as you go and you both see it the same way, what made the situation unpleasant disappears. There is no person doing the reproaching and no person being reproached. There is a number that belongs to nobody and that nobody has to defend.

That is exactly what Kotisso is for. An expense is recorded in ten seconds, in the shop, one-handed, and the other person sees it straight away. Each of you has the same balance in front of you without having to ask, and the balances always add up to zero: there are not two versions of events to reconcile. The split is set once, equally or in percentages if you earn different amounts, and from then on every expense divides itself according to your arrangement. You can attach a photo of the receipt to an expense, so no amount is from memory. And the question of who owes whom how much has a single answer, with no counting.

If the conversation is difficult, the whole record can be exported to a spreadsheet or a PDF and simply put on the table. A document with every line written out can be discussed calmly; a feeling has to be defended.

Frequently asked questions

My partner earns much less than I do. Should they contribute the same amount? They do not have to, and in many couples they should not. A split in proportion to income, say 40% and 60%, is exactly as fair as an equal one, provided it is agreed rather than assumed. The problem this piece is about is not that a partner pays less, it is that nobody agreed how much.

My partner says they pay for the car and the holidays. How do I count that? The same way as the groceries: enter it on their side. The loan payment, the insurance, the fuel, the hotel in summer, everything that is shared goes into one record, on both sides. Only then can you see whether it is a draw, and the result usually surprises both of you, though not in the same direction.

Should I count the small things? Toilet paper, coffee, light bulbs. Yes, and they are usually what makes the difference. Everyone remembers the big expenses. A hundred small ones at 5 € each are remembered only by the person who pays them, and they are where the feeling of paying for everything comes from. Recorded as you go, they cost ten seconds each; counted up after a year, they cannot be reconstructed.

How often should we come back to this? Once a month, for five minutes, on a fixed day. If the balance is fine, the conversation takes a minute. If it is not, it is about one line, not about six months. Settling up daily wears you both out, settling up yearly ends in a row.

How do I work out who owes whom how much when expenses go both ways? Not in your head: with two people and transfers in both directions, memory fails after a month. We set out how to do it in a separate piece on who owes whom.
