How to manage money as a couple

In a nutshell

Money in a couple works better as an agreement than as a fight. You talk without blame, choose a way to split household bills and decide big purchases together. Each person keeps a share for personal spending. A short talk once a month keeps everything on track.

Start with the conversation

Before any math, each person shares what they earn, what they owe and what they usually spend. This is not the time to judge. An old debt or an overspend is information, not a flaw. Pick a calm moment, far from the day a bill is due.

Some questions help:

• How much does each of you actually take home, after deductions?
• What debts does each of you have today?
• What matters to each of you: travel, saving, helping your parents?

Three ways to split

• Half and half: each pays half of the household bills. It is simple, but it weighs more on whoever earns less.
• In proportion to income: each pays the same percentage of their own income. Whoever earns more pays more in reais, but the weight on each wallet is the same.
• All together: all income goes into one pot, and each person gets an agreed amount for personal spending.

There is no right model. There is the one that feels fair to both of you.

Example

Ana and Carlos live in Brazil (R$ is the Brazilian real). Ana earns R$ 3,000 a month and Carlos R$ 2,000. Together: R$ 3,000 + R$ 2,000 = R$ 5,000. Household bills (rent, electricity, groceries, internet) add up to R$ 2,500.

Half and half, each pays R$ 2,500 ÷ 2 = R$ 1,250. Ana has R$ 3,000 − R$ 1,250 = R$ 1,750 left. Carlos has R$ 2,000 − R$ 1,250 = R$ 750 left.

In proportion, Ana earns R$ 3,000 of R$ 5,000, which is 60% of household income. Carlos earns 40%. Ana pays 60% of R$ 2,500 = R$ 1,500. Carlos pays 40% of R$ 2,500 = R$ 1,000. Ana has R$ 3,000 − R$ 1,500 = R$ 1,500 left. Carlos has R$ 2,000 − R$ 1,000 = R$ 1,000 left.

In the proportional model, each one puts half of their own income into the home. The couple found it fairer and chose it.

Household bills and personal spending

Keep two groups. Household bills serve both of you: housing, groceries, electricity, children. Personal spending belongs to each person: a course, a gift for a friend, a hobby. Personal money needs no explanation. That avoids the feeling of being watched.

What about the law?

This guide is about everyday agreements. Who owns what, under Brazilian law, depends on the property regime. In a marriage without a prenuptial agreement, the general rule is partial community of property (Civil Code, art. 1,640). In a stable union (união estável) without a written contract, partial community applies where relevant (art. 1,725). For questions about property, debts or separation, talk to a lawyer or the Public Defender's Office (Defensoria Pública).

Step by step

1. Set a 30-minute talk, and each of you brings your income, debts and fixed costs.
2. List the household bills and add them up.
3. Choose a way to split and work out how much each person pays.
4. Agree on an amount above which no purchase is made without talking first, such as R$ 300.
5. In Meu Gasto, whoever manages the family goes to Settings and taps Invite family member. You both record spending and see household bills in the same place. For the other person to also edit the budget, whoever created the family can make them an admin.
6. Once a month, review the bills, goals and anything that changed together.

Common mistakes

• Talking about money only during a fight. Nobody agrees on anything while angry. Schedule the talk for a calm moment.
• Hiding debts. Debts come out sooner or later and break trust. Share everything at the start.
• Copying another couple's model. What is fair for one couple may not be for you. Do the math with your own numbers.
• Deciding big purchases alone. A big purchase affects both budgets. Respect the agreed amount.
• Never revisiting the agreement. Income changes, children arrive, new goals appear. Review the split when something changes.
