Split Bills Between 4 People
Four housemates means maximum savings and minimum excuses for not having a system. The more people under one roof, the cheaper it gets per head — but the more important it is to have the money stuff sorted from day one.

How 4-Person Splits Work
Four ways is where share house savings really start to shine. A $300 electricity bill? That's just $75 each — less than a decent night out. Dividing everything equally by four is the simplest approach and it's where most bigger share houses begin. Quick maths, everyone pays the same, sorted.
The catch with four people is that differences multiply. You might have two housemates who cook every night running up the gas bill while the other two live on Uber Eats. Someone's always got a space heater going in winter. One person's mates are over every weekend using the wifi. With four people these things can simmer quietly until someone snaps about the power bill in the group chat. Better to flag it early and work out what actually needs adjusting versus what's just normal share house life.
Four-person houses that run smoothly usually keep it dead simple: rent split by room, everything else divided four ways. Trying to track individual electricity or water usage across four people is a fool's errand. The small differences tend to even out over a lease, and the time you'd spend measuring isn't worth the five bucks you might save. Put that energy into agreeing on a cleaning roster instead — that's the real battlefield in a four-person house.
Common 4-Person Share House Expenses
| Expense | Typical Total | Per Person (4-way) |
|---|---|---|
| Rent | $900/week | $225/week |
| Electricity | $375/quarter | $94/quarter |
| Internet | $85/month | $21.25/month |
| Water | $217/quarter | $54.25/quarter |
| Groceries (shared) | $120/week | $30/week |
Tips for Splitting Bills 4 Ways
Appoint a bill wrangler
With four people, someone needs to be across the accounts. Rotate the role every few months so one person isn't stuck being the house accountant forever.
Set up a house bank account
Everyone transfers their share into one account each week. Bills get paid from there. With four people contributing, it smooths out the lumpy quarterly bills nicely.
Agree on thermostat rules
Four people means four opinions on whether it's cold enough for the heater. Set a house rule — say, heater goes on below 16 degrees — and save yourselves the daily debate.
Handle move-outs before they happen
In a four-person house, someone will move out eventually. Agree upfront on how much notice is needed and who's responsible for finding a replacement. It saves a world of stress later.

Questions About Splitting Bills 4 Ways
- Is it cheaper to split bills four ways instead of two or three?
- Absolutely. Rent drops from $450 per person in a two-person house to $225 with four. Electricity goes from $188 each down to $94. Fixed costs like internet barely register at $21.25 a head. More housemates means serious savings across the board.
- How do you manage shared groceries with four housemates?
- At $30 each per week for shared staples, it's cheap as chips. Set up a roster where a different person does the shared shop each week, or use a kitty that everyone tops up. Keep personal food separate and label it if the fridge is a war zone.
- What if one of four housemates uses way more electricity?
- If it's minor, let it go — it'll balance out. If someone's running a crypto mining rig in their room, that's a different story. Have a straight-up conversation and agree on a small surcharge rather than trying to sub-meter the whole house.
- How do four people handle it when someone moves out mid-lease?
- The remaining three cover the gap until a replacement is found. The person leaving should give proper notice and ideally help find their replacement. Sort out who gets the bond back and when — don't leave it to chance or you'll be chasing money for months.
- Do you really need an app to split bills with four people?
- You don't need one, but you'll want one. Four people buying things at different times creates a web of IOUs that gets messy fast. Something that tracks it all and tells everyone exactly what they owe takes about thirty seconds and saves hours of group chat arithmetic.
Done With the Maths?
Four housemates and a whiteboard full of IOUs? There's a better way. Split keeps track of every expense for your 4-person share house so you can get back to arguing about whose turn it is to take the bins out.
