Budgeting as a couple: shared costs made simple

3 min read

Three ways to set up your accounts, and the questions to settle together.

When two people share a home or a life, money questions tend to come up: who pays for what, and how? There is no single right way. This guide uses advice from the Financial Consumer Agency of Canada, a government body, because we could not open a European page on this topic. Account rules and legal rights differ between countries, so treat the points as ideas to discuss.

Start with a conversation

The agency says to talk about money early, especially before moving in together or marrying, so that you both understand each other's finances and attitudes to spending and saving. That conversation is the first step of the budget.

Three common set-ups

1. One joint account for everything. You pool your income and pay all costs from the one account. The agency notes this makes tracking simpler, and says to understand the risks first.
2. A joint account for shared costs only. Each of you keeps a personal account for your own spending. A joint account covers shared items such as groceries, rent or mortgage, and utilities.
3. Separate accounts. You keep finances apart and split shared costs. The agency says this suits couples who value independence, but paying shared bills from separate accounts can be harder to coordinate.

Settle these details

The agency lists three things to decide for shared bills:

• How often money is transferred, based on when you are each paid.
• How much each person contributes, for example 50/50 or in proportion to income.
• What the plan is if one income stops, for example through job loss or illness.

Borrowing together

Joint borrowers share responsibility for a loan. The agency says that co-signing makes you equally responsible for repayment, so agree beforehand how credit will be used and how payments will be shared. The exact rules where you live may differ, so read the loan terms.

An example

These are made-up amounts. Sam earns 3,000 a month and Kim earns 2,000. Shared costs are 2,500 a month.

• Split 50/50: each pays 1,250. Sam has 1,750 left, and Kim has 750 left.
• Split by income: Sam earns 3,000 of the 5,000 total, which is 60 percent, so Sam pays 1,500. Kim earns 40 percent and pays 1,000. Sam has 1,500 left and Kim has 1,000 left.

Neither split is the "correct" one. The example shows that the choice changes how much each person has left, which is worth talking about openly.

Our suggestions for getting started

These are our ideas, not from the agency:

• Write down all shared costs in one list, so you both see the same figures.
• Agree on a small amount each person can spend without asking.
• Check in on the arrangement now and then. A set-up that worked last year may not suit this year. Our weekly money check-in guide can be a template.
• Agree who will keep records, but make sure both of you can see them.

Limits

This is a general overview. Rules about joint accounts, shared debts, marriage and partnership differ by country. If you want a written agreement, the agency says each partner may want their own legal advice before signing. For anything about taxes or the law, ask a qualified local professional.
