Fair expense splitting

Split shared expenses by income—not just 50/50.

Equal amounts can feel unequal when incomes are different. Couplesplit lets a household choose a transparent rule that reflects its reality while keeping every expense visible to both partners.

Choose 50/50, fixed percentages, or an income-based split

Keep one household default without locking every expense

How proportional splitting works

Add both monthly incomes and divide each income by the household total. That percentage becomes the suggested contribution to shared expenses. If one person earns 60% of the total household income, their suggested share is 60%.

Person A: $4,000 of $6,000 total → 66.7%
Person B: $2,000 of $6,000 total → 33.3%
A $1,500 expense becomes $1,000 and $500

A default should reduce work, not remove judgment

The household rule gives everyday purchases a consistent starting point. Couples can still divide one expense differently—for example, a personal upgrade, a gift, or a cost tied mainly to one partner—without rewriting the rest of the month.

Fairness is a conversation, not a formula

Income is only one factor. Debt, caregiving, savings goals, ownership, and personal commitments may matter too. Couplesplit makes the rule explicit and auditable; the couple decides what fair means.
