How to split rent fairly when incomes are different

Why an equal split is not always fair

Splitting rent 50/50 is simple, but if one person earns twice as much as the other, the same dollar amount takes a much bigger bite out of the lower earner's budget. Many couples and roommates prefer a method that accounts for that.

Method 1: Equal split

Best when incomes are similar and the rooms are comparable. It is easy to explain and easy to track. If you pay $2,000 a month, each person owes $1,000.

Method 2: Proportional to income

Add both incomes, then divide each person's income by the total. If one earns $6,000 and the other $4,000, the shares are 60% and 40%. On $2,000 rent that is $1,200 and $800.

Each person then has the same share of their income left after housing, which many people feel is the fairest result.

Method 3: By room size or quality

Roommates often price the rooms differently: the master bedroom with its own bathroom costs more than a small room. Agree on a percentage for each room that adds up to 100%, and use it for rent only.

Keep the other bills separate

Utilities, groceries and internet can follow a different rule than rent. Many households split groceries equally but rent proportionally. Tracking each type of expense with its own split mode keeps the totals clear.
