How to budget as a couple

Start with the numbers, not the opinions

Money arguments are often really arguments about guesses: one person thinks the groceries are too high, the other thinks they’re fine, and neither has looked. Start by putting both incomes and all the household costs in one place where you can both see them. Most of the heat goes out of the conversation once you’re both looking at the same figures.

Our weekly budget guide walks through listing the costs and converting them to a weekly amount. Do that part together.

Three ways to share money

There’s no right answer. Pick the one that feels fair to both of you, and change it if your situation changes.

1. All in together

Both incomes go into joint accounts and everything is paid from there. Simple, and it treats the household as one team. It works best when you have similar views on spending — so pair it with personal money for each of you (below).

2. Yours, mine and ours

Each of you pays an agreed amount into a joint account for shared costs (rent or mortgage, power, groceries, the bills) and keeps the rest in your own account. This is the most common middle ground.

3. Split the bills

You keep your money separate and split each shared bill. It’s easy to start with but takes more admin, and it can feel transactional over time.

Equal or in proportion?

If you earn quite different amounts, splitting 50/50 can leave one person with much less left over. Many couples contribute in proportion to income instead. For example, if one of you takes home $1,200 a week and the other $800, that’s 60/40: on $1,000 a week of shared costs, $600 and $400. Neither is “right” — just agree it out loud.

Keep some personal money each

Give each person the same amount of personal spending money a week that the other doesn’t question: a coffee, a hobby, a present for your partner. It removes most of the small, irritating money conversations, and it means nobody needs to ask permission for every purchase.

The weekly money check-in

Pick a time each week — 15 minutes is plenty — and keep it routine rather than a crisis meeting:

1. What came in, what went out, and what’s left this week?
2. Any bills coming up in the next few weeks?
3. Is anything over budget, and is it a one-off or a pattern?
4. How are the shared goals going (holiday, house deposit, paying down debt)?

Keep it about the plan, not about blame. If a line keeps going over, the budget for it is probably unrealistic — change the number rather than arguing about it every week.

How Jarful helps

Jarful is one plan for the household, and it includes your partner: you both see the same budget, the same transactions and the same “what’s left this week”, on your own phones or computers. Weekly and monthly budgets, one-offs and the 12-month forecast work the same for both of you. See pricing — there’s a 14-day free trial, no card required.
