How couples split bills fairly: four ways that work

There's no single right answer — only the one you both think is fair. These are the four approaches most couples use.

1. Split everything 50/50

Simple and easy to track. Works best when incomes are close; it can pinch the partner who earns less.

2. In proportion to income

Each pays the same percentage of what they earn. If one takes home $6,000 a month and the other $4,000, shared bills split 60/40. Fair on effort, a little more arithmetic.

3. One shared pot

Both pay in (equally or by income) and every shared bill comes out of it. Less tallying, but agree on what counts as shared.

4. By category

One pays the rent, the other the utilities and groceries. Easy day to day; check every few months that it still feels even.

Whatever you choose

• Write down what's shared and what's personal.
• Keep a running tally rather than settling every bill.
• Even up once a month in as few payments as possible.

Convivo keeps that tally for you: record who paid each shared cost and how it's split, and it shows who owes whom and the fewest payments to settle. See how it works.

Questions

Should couples split bills 50/50?

50/50 is simple and works well when incomes are similar. When one partner earns much more, splitting in proportion to income often feels fairer because each pays the same share of what they earn.

How do you split bills proportionally to income?

Add both take-home incomes, work out each person's percentage, and each pays that percentage of shared bills. If one earns $6,000 and the other $4,000 a month, they pay 60% and 40%.
