Question 1

Should couples split expenses 50/50 or by income?

Accepted Answer

50/50 works when incomes are similar. When they differ, an income-proportional split puts the same percentage burden on both partners — if you earn 60% of the household income, you cover 60% of shared costs. Most financial advisors consider proportional the fairer default for unequal incomes.

Question 2

Which expenses count as shared?

Accepted Answer

Typically rent or mortgage, utilities, groceries, household supplies, subscriptions you both use, and joint travel. Personal subscriptions, hobbies, and gifts stay personal. A short shared list is easier to keep honest than a long one — when in doubt, call it personal.

Question 3

How do we track who actually spent what?

Accepted Answer

Each partner tracks their own spending, then you compare shared-category totals once a month. The system only works if logging is effortless — that's why apps with voice input and Apple Pay auto-import beat shared spreadsheets in practice. See our guide on budgeting as a couple with separate accounts.
