How to start a house fund with your roommates
What runs out in a shared home always seems to land on the same person: toilet paper, bin bags, detergent, a light bulb. Working out who bought what and who owes how much for tiny amounts is tiring. The fix is a house fund.
Below you will find how a house fund works, how to set the monthly amount, the rules to agree and how to keep records.
What is a house fund?
It is a common pot into which everyone pays a small equal amount each month. Small household costs are paid from the pot, so nobody needs to calculate every bin bag; when it runs low it is topped up.
What does it cover?
| Paid from the fund | Not from the fund |
|---|---|
| Toilet paper, paper towels | Personal food and drink |
| Detergent, dish soap, sponges | Personal care products |
| Bin bags, bulbs, batteries | Big household items (decide separately) |
| Small repair supplies | Rent and bills (split separately) |
| Shared oil, salt, spices | Guest hosting costs |
For bigger costs see our shared expenses list; keeping rent and bills outside the fund keeps things simple.
How to set the monthly amount
- Add up the small shared costs for the last two months (from receipts and messages).
- Work out the monthly average.
- Divide by the number of people and round up.
For example, if small shared costs in a three-person home average $54 a month, that is $18 each; rounding up to $20 each gives a $60 fund and a little buffer. Watch it for the first three months and adjust.
Rules: short and clear
- Pay-in day: the same day each month (rent day works).
- Who holds it? One person or a separate account; what matters is that everyone can see the balance.
- Spending limit: anything above a set amount (say $30) is announced first.
- Receipt or note: every spend is recorded.
- Leaving: the leaver's share of the balance is returned.
You can add these to your house rules.
How to keep the record
The one risk of a house fund is a lack of transparency: if nobody can say how much is left, trust suffers. A simple sheet can be enough (Excel expense tracker), or in Ev Ortağım add each fund purchase as an expense split equally; the monthly summary shows the total and who paid.
If the numbers don't add up, read our guide to tracking who owes what.
When to skip the fund
- The first months, while trust is still being built.
- When people consume very differently, for example someone is rarely home.
- Short lets where there is too little time to set one up.
In these cases everyone can record what they buy and split equally at month end; the grocery guide shows how.
