Shared household expenses list: what roommates split
Everyone in a shared home asks the same thing: "Is this a shared cost or mine?" Without a clear list, tiny amounts turn into big arguments. The fix is to write down which costs are shared as soon as you move in.
Below you will find the common categories, a split suggestion for each and a short method for making your own list.
What counts as a shared expense?
A shared expense is a cost everyone in the home uses or benefits from. A personal expense is only used by one person. The line is sometimes blurry (a coffee machine, say), so it is best to make the list together up front.
The usual list
| Expense | Usually split |
|---|---|
| Rent | Equally or by room size |
| Building fees | Like rent |
| Electricity, water, gas | Equally; by days after a long absence |
| Internet | Equally |
| Cleaning supplies | Equally (shared shopping) |
| Shared groceries (toilet paper, oil, salt, detergent) | Equally or from a house fund |
| Household items (vacuum, pans, shared TV) | Equally; whoever buys |
| Small repairs | Equally, or tell the landlord |
| Trash bags, light bulbs, batteries | House fund |
For bills see our guide to splitting utility bills, and for rent options rent and bills.
The grey areas that cause arguments
- Shared food: Breakfast basics and milk may be shared, while things only one person eats stay personal. Pick one clear method (grocery guide).
- Subscriptions: A shared TV or music account. Someone who doesn't use it may not need to pay.
- Guest costs: Whose account do a guest's meals and extra power go on? Agree beforehand.
- Who owns shared things: When you move out, who keeps what you bought together? See moving out.
- Heating and air conditioning: If usage differs a lot, consider splitting by days or by device.
Make your own list in four steps
- Write everything down: every cost you can think of in a month and a year.
- Sort into three columns: shared, personal, disputed.
- Talk through the disputed ones: decide equal, by use or personal for each.
- Write it and share it: put the decision somewhere permanent, not in a chat. It can be a clause in your house rules.
A house fund for small things
Doing the maths for toilet paper, bin bags and detergent every time is tiring. The fix is a house fund: everyone puts in a small amount each month (say $20), small shared costs are paid from it and it is topped up when it runs low. See how to start a house fund.
Why keeping a record matters
If an expense is shared it needs a record. Without the date, who paid and how much you can't make a fair settlement at month end. In Ev Ortağım you can add each expense with its category, date and split, and the monthly summary shows the total and who paid what. You can also use the Excel expense tracker.
