Short answer: Stop negotiating who pays what every single time. Instead, track everything automatically and settle once a month. The app shows who owes whom — no awkward conversations, no "you owe me €23" texts.

Money is the #1 cause of conflict in couples. Not because you're incompatible, but because nobody ever taught you a system. This guide skips the generic advice and goes straight to what actually works.

Why couples fight about money (the real reasons)

It's rarely about the money itself. Couples fight because of:

Ambiguity: "I thought you were paying for that"
Lack of visibility: one person feels they pay more but has no data to prove it
Recurring conversations: "Can you transfer me the grocery money?"
Different money values: one saves, one spends — with no explicit shared system
Imbalance that builds up: small differences that compound into resentment

The solution isn't a difficult money conversation. It's a system that makes that conversation unnecessary.

5 methods to split expenses without arguing

1. 50/50 — Split everything down the middle

All shared expenses are divided equally. One person pays today, the other tomorrow, or you settle at the end of the month.

✅ Works when: similar incomes, both working, want simplicity

❌ Fails when: very different salaries, one is a student or part-time

2. Proportional to income

Each pays according to what they earn. If one earns twice as much, they pay twice as much of shared costs. Requires transparency about salaries.

✅ Works when: significant income gap, long-term relationships, good communication

❌ Fails when: reluctance to discuss salaries, income changes frequently

3. Joint account for shared expenses only

Each contributes a fixed monthly amount to a shared account. All household expenses come from that. Personal money stays separate.

✅ Works when: predictable fixed costs, want clear separation of personal and shared

❌ Fails when: high variable costs, forget to top up the account

4. One pays, both track — settle monthly ⭐ Most effective

It doesn't matter who pays at any given moment. Every expense is logged with who paid and what it was for. An app calculates the running balance. At the end of the month, whoever owes pays in one transfer.

✅ Works for: virtually any couple. Most flexible, eliminates daily negotiation

❌ Fails when: not tracking consistently (takes 5 seconds in Splitt)

5. Category split

One person handles certain categories (e.g. rent and utilities), the other handles others (groceries and transport). Simple for fixed costs, messy for variable ones.

✅ Works when: very regular expenses, neither wants to track anything

❌ Fails when: one category grows faster than the other and nobody rebalances

Our recommendation: Method 4 — track everything in Splitt, settle once a month. No daily negotiation, no "who paid for the Uber last week?". Just data.

The one conversation you need to have

You don't need to talk about money every week. You need one 30-minute conversation to agree on a system:

What counts as a "shared expense"? (rent, groceries, utilities, joint outings)
50/50 or proportional to income?
How often do you settle? (monthly is easiest)
Which app for tracking?

Once you've had that conversation, the system runs itself.
