Frequently Asked Questions
How do you fairly split utilities between roommates?
The most common approach is an equal split -- divide each bill by the number of roommates. If fairness is a concern, you can split by room size or by usage. This calculator supports both equal splits and custom percentages.
Who is typically responsible for paying utility bills?
Usually one person puts each utility in their name and collects from the others. ExpenDiv is built for exactly this situation -- the bill owner tracks what everyone owes and sends automated payment reminders so they do not have to chase people manually.
What utilities do most roommates split?
The most common shared utilities are electricity, internet, water, and gas. Some households also split trash collection, streaming subscriptions (Netflix, Spotify), and renter's insurance.
Should you split utilities equally or by usage?
Equal splits are simpler and work well when usage is similar. Splitting by usage is fairer when there is a meaningful difference -- for example, if one roommate works from home and uses significantly more electricity.
How do you track who has paid their share of utilities?
After you calculate the split here, add each bill to ExpenDiv to track paid and unpaid status and send automatic payment reminders. Your roommates receive an email with a payment link -- no account required on their end.
