Where your pay goes: impulse spending and how to see it

You can remember paying rent and buying groceries, but the rest of your pay is harder to explain. There wasn't one enormous purchase. There was a delivery order, a sale you didn't want to miss and a few things that felt small at the time.

I'd start by finding those purchases before trying to cut anything. You might find a habit worth changing, or that the ordinary cost of getting through the fortnight leaves less room than you thought. Both are useful things to know.

What counts as an impulse spend?

An impulse spend is a purchase you decide on the spot, before giving yourself time to check whether you want it and can afford it. It might be a jacket you found while scrolling, or an extra item added to reach free delivery. Moneysmart's guidance on sales pressure describes how discounts and easy checkouts can prompt exactly these quick decisions.

What matters is how the decision happened, not what you bought. Dinner with friends that you planned and put money aside for is a want, but it isn't an impulse buy. Replacing broken work shoes may be necessary even when you weren't expecting the cost. Calling every purchase outside rent and groceries an impulse spend would make this exercise pretty miserable.

A subscription you forgot about belongs on a different list. If renewals are taking money you'd rather keep, review and cancel those subscriptions separately.

Find the moments that catch you

Most impulse spending has a moment behind it. A sale gives you a deadline. Late-night scrolling puts a shop in front of you when you weren't looking for anything, and a saved card or one-click button lets you finish before you've checked your balance. With friends, the pressure is quieter: someone suggests another round or a pricier venue, and saying yes feels easier than explaining your budget.

So look at the moment just before each purchase. Were you buying something you'd already chosen, or did a notification, a friend's suggestion or a countdown choose the moment for you? Black Friday and Christmas are worth watching, because a planned gift shop can easily turn into buying extras for yourself.

Look through one pay cycle

One pay cycle, from the day your last pay arrived to the day before the next, is long enough to show a pattern and short enough to finish in one sitting. Gather the transactions from every account and card you spent from, plus any buy now pay later purchases. If you'd rather not sort them by hand, Clova (the budgeting app we're building) puts each purchase in a category for you so you only need to spot the ones you hadn't planned.

1. Make one purchase list. Leave out transfers between your own accounts, and if you've listed a card purchase, don't count the card repayment again. Add cash purchases you remember and mark any cash you can't account for as unknown.
2. Mark the impulse purchases. Look for things you bought on the spot without checking whether you wanted them or whether they fitted your plan, and jot down what prompted each one. Keep unexpected necessities, like those work shoes, and anything you're unsure about separate rather than guessing.
3. Add up the marked purchases. Look for a repeated situation as well as the total. Several delivery orders after late shifts point to a different next step than one sale purchase you regret.

Buy now pay later needs one extra step. Put the full price on your purchase list on the day you bought it, then keep each remaining instalment and its due date in your cash plan for the pays ahead; Moneysmart recommends budgeting for them alongside your bills. Repayments for things you bought before this pay cycle stay off the purchase list, but they still belong with the payments this pay has to cover. Our guide to how buy now pay later fits your budget shows how those instalments line up with paydays, and the guide to reviewing spending across accounts walks through matching everything up.

A fortnight where the small purchases add up

Here's a made-up fortnight in Australian dollars, with $1,600 of take-home pay and no starting balance. The amounts are an example, not typical costs for young Australians, and everything is paid from this pay, with no credit, refunds or money owed back by friends.

Each square is $20

• Essentials$1,080
• Savings$160
• Planned fun$120
• Unplanned$180
• Left$60

The unplanned purchases are where the review gets useful, because each one has a reason you can do something about.

The $120 of planned fun stays in the plan. For next fortnight, you might mute the shop's notifications and keep an easy dinner at home for after late shifts. That targets $133 of these purchases. It won't catch every one, but it's a specific place to start without giving up every night out.

The $60 left also needs a second look. In this example everything due is covered, but in your own account that balance might have a bill waiting behind it, so check what's left before payday before treating it as spending money.

Put a pause before the checkout

If online shopping is the pattern, remove your saved card from that shop and your browser, log out of the shopping app and mute its sale notifications, so finding the card gives you a moment to reconsider. If the extra spending happens with friends, decide what you can spend before you go; suggesting somewhere cheaper is much easier before everyone has ordered.

For unplanned shopping, a wish list with the item, its full delivered price and the date works well. Moneysmart suggests waiting at least 24 hours. That's a useful pause rather than a cure, and if a purchase would use money set aside for a bill, I'd leave it until you've worked out how to cover both.

You can also give fun money its own line in your budget: money for things you enjoy once essentials and commitments are covered. In the example, the planned $120 already has that job and the unplanned $180 sits on top of it. A fun-money amount lets you choose the purchases you care about, instead of finding out afterwards what they cost together. If you'd like a starting structure, the 50/30/20 rule explains how needs, wants and savings fit together, though you don't need to force its percentages onto a pay that can't cover them.

Give the next pay a plan

Try the budget planner with your own take-home pay, bills and a fun-money line, including costs that haven't left your account yet. Then you can check a purchase against money that's actually available, rather than the balance on the checkout screen.

Keeping that picture up to date each fortnight is the fiddly part. Clova shows what's available after bills and budgets each pay cycle and how each category moved since the last one, so you know where to look first. Join the waitlist.

Before Black Friday and Christmas shopping

For Christmas, set a total for the whole list first, then a maximum delivered price for each item before you open the sales. Include something for yourself if it fits. That gives a discount a useful job: making something you'd already chosen cost less.

The ACCC's Black Friday warning to retailers flagged misleading limited-time offers and broad discount claims, and encouraged shoppers to check prices before sales start. Comparing the exact item across shops, delivery included, tells you more than the crossed-out price does.

If something extra turns up, it gets the same pause as any other unplanned purchase. A sale ending doesn't make the next pay arrive any sooner.

If you only change one thing this fortnight

Pick the repeated purchase you'd most like to make less often, and change what happens just before it. At the next payday, look for that pattern again. You don't have to solve every spending habit at once to make the next fortnight easier to understand.

A note from us

We believe a budget should leave room for enjoying money. Understanding an unplanned purchase can make the next decision clearer without turning every small pleasure into something to defend.
