  • This money diary follows an 18-year-old Sydney student juggling two part-time jobs while attempting to save $10,000 for a dream gap year.
  • A financial health check from a money coach proves that small luxuries like iced matchas and bubble tea are often a young saver's biggest budget leak.
  • Transitioning from parent-enforced boundaries to automated independent savings is an important step for beginners learning how to better spend money long-term.

Building a student budget

Juggling two part-time jobs – looking after kids at an after-school care facility and running her own cat-sitting business – this 18-year-old student based in the inner city of Sydney is no stranger to the hustle. She’s banking her earnings with two major milestones in sight: funding a dream gap year and covering her ongoing university tuition. But while living at home provides a near cost-free safety net, she worries her savings rate is falling short. The main culprit? Sydney's vibrant cafe culture right on her doorstep. 

My money story  

“I pride myself on the fact that I’ve never been a mindless consumer. I’m not interested in fast fashion or stuff, but I’ll blow my money at cafes and restaurants. I know my sweet treat obsession concerns my parents. My mum’s so worried I’ll spend whatever I earn that she supports me by putting half of everything I make into a term deposit.  

"I would like to have at least $10,000 saved towards a gap year – I’ll work between trips to earn more money – plus anything else I can get together to put towards my uni fees. I’ve got $7,000 saved so far. I’m worried about two things: having to stay in the worst hostels you can imagine and starting my career with a huge debt.” 

My weekly spending

Living at home keeps this Sydney-based student’s living overheads low. Here is a snapshot of her day-to-day spending over the course of a typical week.

Monday: $0 

I like to start my week by treating myself to an iced matcha at my local cafe. It’s normally $6.50 but I was up to my freebie on my loyalty card, so I didn’t pay a cent. I still live at home so my parents usually cook dinner. Tonight was vegetable lasagne and salad which was super tasty - and free!

Tuesday: $9.80

I’m trying to get into the habit of making my own coffee at home, but I bought sushi for lunch on the way to the library - I’m studying for a Bachelor of Arts degree. 

Wednesday: $41

I order another iced matcha ($6.50) and a cheese toastie ($4.50) as a snack before hitting up Brandy Melville to buy a $30 shirt for my friend’s birthday.

Thursday: $33

My afternoon Westfield mission for (parent-funded) art supplies goes off-track when I buy myself a cute pair of gold earrings for $25 (they were on sale). I grab a bubble tea ($8) from Chatime on the way home.

Friday: $58

My friends and I usually hang out at the local pool hall on a Friday night where we take turns paying the hourly fee. This week it’s my turn, and after I pay $40 for a two-hour slot, my Betty’s Burgers meal ($18) wipes me out. 

Saturday: $0

I’m working on an art project at home so it’s a pretty low-key day. I don’t spend anything, which feels like a relief. 

Sunday: $20

It’s my friend’s birthday picnic and we’ve all been assigned with contributing to food. I do a supermarket run on the way and pick up a couple of dips, crackers and a packet of Tim Tams for about $20. I probably should have spent a little less.  

Total spend: $161.80 

The expert view: Set limits and build a buffer

Fortunately, Karen Eley, certified money coach at Women Talking Finance, has a roadmap to turn this student’s gap-year dreams into reality without sacrificing her daily cafe joys. To start, Eley says she should recognise that banking 50 per cent of her earnings via her parents is a great safety net. 

The next step from here would be to begin taking the savings guidance from her parents and running with it. “It would be beneficial to start your own saving discipline rather than relying on your parents,” says Eley.

To build that independence, Eley recommends opening a separate account and automating a $20 weekly transfer, effortlessly banking $1,000 over the year. “Creating the habit of saving early sets you up for financial success,” Eley says. “And it gives you a vital buffer for gap-year emergencies.”

Next, it's worth setting a budget to cap her spending on luxuries like jewellery and clothes. “Setting a guilt-free spending amount may be useful,” Eley advises. But the rule for that spending bucket is absolute: “When it’s gone, it’s gone.”
