Split rent and bills with roommates
Rent, power, internet, cleaning supplies and the shared grocery run — Sumzy keeps a running balance for everyone in the house, so nobody has to keep score.
How to split house bills in Sumzy
- Create a home group and add your roommates by email.
- Add each bill with who paid it. Split it equally, or unevenly — by exact amounts, percentages or shares, for example when one room is bigger.
- Settle up when it suits the house — monthly, or when someone moves out. Sumzy shows the fewest payments that zero everyone out.
What makes it work for a shared house
One balance per person
Every expense updates who owes whom. Open the group and you see each roommate's balance, not a pile of receipts.
Fair when it isn't equal
The bigger room pays a larger share of the rent; someone who is away for a month skips the groceries. Choose the people and the split per expense.
Recurring bills with Pro
With Sumzy Pro, rent and subscriptions can repeat weekly, monthly or yearly and are added automatically, with an optional end date. On the free plan you add each bill yourself, up to 7 new expenses a day.
Moving out cleanly
A member can leave a group once their balance is zero, and everything already recorded stays in the group's history.
Example: a three-person house
Rent is R$3,000. Diego has the biggest room, so the house splits rent 40/30/30: Diego R$1,200, Elisa R$900 and Fábio R$900. Elisa pays the internet bill of R$120, split equally. Fábio buys cleaning supplies for R$60, also equal.
Each expense updates one running balance per person. At the end of the month Sumzy shows the fewest payments that settle the house — often just one or two transfers instead of one per bill.
Tips for splitting bills with roommates
- Agree on the rules once. Decide which bills are equal and which follow room size, then use the same split every month.
- Keep personal purchases out. Only shared costs go in the house group; Sumzy has a separate personal side for your own spending.
- Pick a settle-up day. Many houses settle on rent day, so balances never grow for months.
- Export when someone leaves. You can export your data from the app if anyone wants a record.
Frequently asked questions
Can Sumzy add the rent every month automatically?
Yes, with Sumzy Pro: recurring expenses repeat weekly, monthly or yearly on their own. On the free plan you add the rent each month yourself.
Can we split the rent unevenly?
Yes. Split by exact amounts, by percentage or by shares, so a bigger room can pay a bigger part.
What happens when a roommate moves out?
Settle their balance to zero and they can leave the group. The history stays for everyone else.
Do all roommates need to install the app?
No. You can add a roommate by email and their balance is tracked straight away; they see it when they sign in with that email.
