Income Based Rent Split Calculator

Split a shared bill in proportion to each person's income, not evenly.

A fairer way to split

Splitting a shared cost evenly is simple but not always fair — when housemates or partners earn very different amounts, an equal split takes a much bigger bite out of the lower earner. This splits a bill in proportion to income instead, so each person pays a share that reflects what they can afford.

Enter the total and each person's income to see the proportional shares.

When proportional beats equal

Proportional splitting is increasingly used by couples and households for rent and shared expenses, precisely because an equal split can feel unequal when incomes are far apart — the same rent is a small fraction of one salary and a huge chunk of another. It is not the only fair approach, and what feels right is a conversation for the people involved, but having the proportional figures on the table gives a concrete, transparent starting point.
