You can split your rent with roommates using various methods, including:Even split: In this method, the total rent – including utilities and miscellaneous household expenses – is divided evenly between each roommate.Income split: If roommates have substantially different salaries, it may make sense to split the rent based on each person’s monthly income. By adding every income together and finding each person’s income percentage, roommates can determine what percent of the rent they should be responsible for.Square foot split: If bedrooms, bathrooms, closets, and common areas vary significantly in size, roommates may decide to split the rent based on the amount of space each occupies. Simply divide the square footage of a living space by the total square footage of the home, and multiply that percentage by the total rent payment.
