How the deposit split works
Each roommate gets back what they paid in, minus their part of the shared deductions, minus any damage they caused themselves. Shared deductions are usually things like general cleaning or common-area wear. They're split either in proportion to what each person paid in or equally.
See the guide to splitting a security deposit and the roommate move-out money checklist. Final bills? Use the prorated utilities calculator.

Frequently asked questions
How do roommates split a security deposit refund?
Each person usually gets back what they paid in. Shared deductions come out in proportion to what each person paid in, and damage caused by one roommate comes out of that roommate's share only.
What if a new roommate replaced someone mid-lease?
Usually the incoming roommate pays the outgoing one directly for their share of the deposit. Enter the current roommates with what they effectively paid in.
What if deductions are larger than the deposit?
Billsplitly shows a negative refund. That roommate owes the difference, which is often charged by the landlord separately.
Who gets the refund check?
Landlords often send one check to the person named on the lease. That person then pays everyone else the amounts shown here.
