Chloe and the stack

Chloe is 20, studying two days a week and working at a supermarket for about $610 a fortnight after tax. In March she wants a $340 pair of sneakers she has been circling for a month. At the checkout there is a button: four payments of $85, first one today, no interest. She taps it. The instalments come out on schedule, she barely notices them, and six weeks later the sneakers are hers, fully paid. It could not have gone better, and that is precisely the problem.

Over the next three months the button gets easier. On her first service she adds a $180 dress for a wedding, $120 of gig tickets and $260 headphones. When that app starts feeling watched, a second service gets a $150 birthday present for her mum and a $220 clothes order. None of these felt big. A dress was $45 a fortnight. Headphones were $65. In May she also gets her first credit card, a $1,500 limit at 20.99%, and a festival weekend swallows the whole limit in four days: ticket, camping gear, fuel and the blur in between. When the statement arrives she pays the minimum, $30, and tells herself she will sort it out next month.

By June her fortnight looks like this. Because every pay later purchase starts its own schedule from its own date, the instalments land scattered across the fortnight rather than on one day: $45 for the dress on a Monday, $30 for the tickets that Wednesday, $65 for the headphones the following Tuesday, $37.50 for the present and $55 for the clothes order on two different Fridays. That is $232.50 a fortnight in instalments out of $610 in pay, before rent share, food, fuel or the card. No single payment is frightening. The pattern is.

Twice in June her account runs dry on the wrong day. The headphones instalment bounces on a Tuesday when payday is still two days away, and a fortnight later the clothes instalment does the same. Each miss costs a $10 late fee. Twenty dollars for the crime of being paid on Thursdays.

The card is quieter and worse. At 20.99%, the interest on her $1,500 balance runs to roughly $26 a month. Her $30 minimum payment covers the interest and about $4 of actual debt. After two months of paying the minimum she has handed over $60 and owes $1,492, eight dollars less than where she started. Out of curiosity she checks what the statement fine print means: paying only the minimum, a balance like hers would take roughly a decade to clear and cost well over $1,000 in interest along the way, approximately. She reads that number three times.

On the last Sunday in June, Chloe sits down and does the thing she has been avoiding: she writes every debt on one page, smallest first.

• Gig tickets: $60 remaining, $30 a fortnight
• Birthday present: $75 remaining, $37.50 a fortnight
• Wedding dress: $90 remaining, $45 a fortnight
• Clothes order: $110 remaining, $55 a fortnight
• Headphones: $195 remaining, $65 a fortnight
• Credit card: $1,492 at 20.99%

Total: $2,022. Scary, but smaller than the shapeless dread it replaces. Then she moves. Both pay later apps are deleted and the accounts closed to new purchases. The card comes out of her phone wallet and lives in a drawer. She picks up one extra shift a fortnight, worth about $170, and cancels two subscriptions she had stopped noticing. The instalments stay on autopay, but now she keeps a buffer in the account so nothing bounces again: the pay later debts are interest free, so the only way they can hurt her from here is another late fee.

July is the grind month: the instalment schedule runs itself down, and the smallest debts fall off the page one by one, each cleared plan freeing up its fortnightly payment for the next. By the second week of August the last instalment is paid and every spare dollar turns on the card. She puts about $700 a month at it through August and September, and in the last week of September the balance reads zero. Total time from the list to clean: three months. Total cost of the detour, beyond the things themselves: $20 in late fees and roughly $110 in card interest, approximately. Cheap, she decides, for what it taught her, and she keeps the one page list as a souvenir.

What she does differently now is small and boring, which is the point. The credit card stays, because closing it would not help and a card paid in full quietly builds the repayment history the credit scores lesson describes, but the full closing balance comes out by direct debit on the due date, so the interest free period is permanent and a month like May cannot happen again. Both pay later apps stay deleted. When she wants something she cannot pay for today from her own account, she has a rule she wrote herself, and the rule is that it waits until she can, because splitting a price into four never made it affordable. It only made it four.
