How to budget with your partner
Decide what counts as a shared expense, pick a split rule, put the numbers somewhere you can both reach, and review them once a week. The mechanics are simple. What makes couple budgets fail is not arithmetic, it is that one person ends up being the accountant and quietly resents it.
Start with what is actually shared
Before any app, write two lists. Shared: rent or mortgage, utilities, groceries, transport you both use, anything for children or pets. Personal: clothes, hobbies, lunches at work, gifts for each other.
Most arguments about money are really arguments about which list something belongs on. Settling that once, in a calm moment, removes the recurring version of the argument.
Pick a split rule and write it down
Two rules work. Equal halves is simplest and fair when incomes are close. Proportional splitting means each person covers the share of the joint costs that matches their share of the joint income: if you earn 60% of the household total, you cover 60% of the rent.
Either is defensible. What is not defensible is an unwritten rule, because unwritten rules get re-argued in a supermarket queue.
You do not need a joint account
A joint account is one way to pool money. It is not required, and for a lot of couples it is a bigger step than the budget needs. What you actually need is a shared view: one place where both people can add an expense and both people see the same total.
Keeping separate accounts and a shared budget is a perfectly ordinary arrangement. It also avoids the awkward conversation about closing accounts if things change.

Enter as you go, not once a month
Batch entry at the end of the month is how budgets die. You forget the small ones, the total looks wrong, you stop trusting it, and then you stop opening it.
Entering an expense takes a few seconds at the till. Because it is manual, it is also the moment you notice the fourth coffee of the week, which no automatic import will ever make you feel.
The weekly check-in
Fifteen minutes, same time each week. Read the category totals out loud, notice anything surprising, adjust one limit if it was wrong, and stop. Longer sessions do not produce better budgets, they produce fewer sessions.
The point of the ritual is that neither person is the accountant. You are both looking at the same screen at the same time.
Questions people actually ask
Should we combine all our money?
You do not have to. A shared budget only needs a shared view of the joint spending. Plenty of couples keep separate accounts and share the budget, not the balance.
What if one of us earns much more?
Split the joint costs in proportion to income rather than in half. Each person then gives up the same share of what they earn, which usually feels fairer than an equal amount.
