Interview with a graduate: budgeting together in shared living

How do you and your housemates organise your shared budget?

I live in Melbourne with two flatmates, and we decided early to set up a simple budgeting system for the household. Every month, we meet to talk about upcoming expenses, whether it’s bills, groceries, or shared supplies. We use a spreadsheet that everyone can access, and each person is responsible for adding their own purchases. This routine means nothing gets missed, and everyone has a say in what’s bought and how much we’re spending.

What has worked best and what’s been most challenging?

The best thing about our system is how transparent it is. No one feels like they’re paying more or less than their fair share, because everything is out in the open. The biggest challenge is agreeing on priorities — sometimes, we have different opinions about what’s essential. We’ve learned to talk it out and compromise, which makes budgeting less stressful for everyone.

Were there any mistakes early on, and how did you address them?

At first, we didn’t have a clear process for tracking group spending, so it was easy for things to get missed or duplicated. After a few mix-ups, we made a habit of logging expenses as soon as they happen and reviewing the spreadsheet together. Now, we’re more organised and there’s less confusion.

Do you have any advice for people new to budgeting with roommates?

If you’re just starting out, set up a shared tracker as soon as possible and talk about expectations openly. Decide together how you’ll split costs and what happens if something unexpected comes up. Don’t be afraid to revisit your process if it isn’t working — adjustments are part of the process. Most importantly, be patient and keep the conversation going, even when it feels awkward.

Has this experience changed how you approach money in other areas of your life?

Collaborative budgeting has taught me that being organised is only half the story. The real value is in building trust and keeping everyone involved. I’ve carried those lessons into my work and friendships — it’s about listening, adapting, and making space for everyone’s voice.
