The short answer

Couples usually share costs in one of two ways: 50/50, or in proportion to their incomes. 50/50 is simple when you earn about the same; a proportional split is often fairer when one of you earns noticeably more. Whichever you pick, agree on which costs are shared and check the balance once a month.

Fair does not always mean half

Use an equal split for day-to-day costs, or percentages when one of you earns more: for example 60/40 on rent and groceries. Each expense can have its own split, so a birthday present for your partner’s family can be paid differently from the weekly shop.

Example: 50/50 or in proportion to income

Mia takes home €3,000 a month and Noah €2,000, so a split by income is 60/40. Their shared costs are €1,850 a month. This is what each of them has left for themselves:

Shared costs of €1,850 a month
PartnerIncomeShare at 50/50Left at 50/50Share at 60/40Left at 60/40
Mia€3,000€925€2,075€1,110€1,890
Noah€2,000€925€1,075€740€1,260

How the month settles

Mia pays the rent (€1,200); Noah pays groceries (€500) and energy (€150). With a 60/40 split Mia’s share is €1,110 and she paid €1,200, so Noah transfers €90 to even out. One payment a month, no joint account needed.

Three common ways couples organise money

Fully joint: everything goes into one pot. Simple, but it needs a joint account and full agreement on spending.

Shared costs only: each keeps their own money and splits shared costs, 50/50 or by income. This is what MySharedXP is built for.

Yours, mine and ours: personal money stays personal, and a shared group covers the household, holidays or a wedding. You can keep a separate group for each.

Which costs count as shared

Agreeing on what is shared matters more than the percentage. This is how most couples sort their costs:

  • Usually shared: rent or mortgage, energy, water, internet, groceries, household items, holidays together
  • Often shared: eating out together, a car you both use, pets, gifts for family
  • Usually personal: clothes, hobbies, gym, personal subscriptions, gifts for each other

A short monthly money check-in

Look at the balance together once a month: settle it, check whether the split still feels fair, and adjust the percentages if an income has changed. With Pro, spending insights show where the shared money went by category, which makes the conversation about facts rather than feelings.

Everything in one place

Useful for couples:

  • Percentage and share splits for income-based sharing
  • Separate groups for home, holidays or a wedding
  • Spending insights by category (Pro)
  • Budgets and recurring expenses (Pro)
  • Private: only the two of you see your groups

Questions and answers

How do couples split expenses fairly?
The two common ways are 50/50 or proportional to income. With MySharedXP you can use percentages for proportional sharing and change the split per expense.
How do you split costs in proportion to income?
Add up both take-home incomes and work out each person’s percentage: €3,000 and €2,000 make 60% and 40%. Use those percentages as the split for shared costs, and update them when an income changes.
Is a shared budget better than separate budgets?
Neither is better for everyone. Many couples keep their own money and share only the household costs, which keeps independence and fairness. A budget for shared categories, such as groceries, helps you both see where the money goes.
Do we need a joint bank account?
No. MySharedXP tracks who paid what and tells you how much to transfer to even out, so you can keep separate accounts.
How often should couples settle up?
Once a month is common, or whenever the balance gets large. Some couples never settle in full and simply let the person who owes pay the next big bill.
What if one partner earns much more than the other?
Then a split in proportion to income is often fairer than 50/50, because both of you keep a similar part of your income for yourselves. Some couples go further and let the higher earner cover certain costs, such as holidays, in full.
Should we split dates and gifts?
That is up to you. Many couples take turns paying for dates and keep gifts for each other personal, and split only gifts they give together. In MySharedXP you simply leave out what you do not want to share.
Can anyone else see our expenses?
No. A group is visible only to its members, and your data is encrypted and never sold.
