How do I even pick avalanche vs snowball?

Highest rate first, or smallest balance first. Pick the one you’ll still be doing in three months.
Avalanche and snowball are two ways to send extra money at debts you already have. Avalanche puts the extra on the highest interest rate first. Snowball puts the extra on the smallest balance first. You still pay at least the minimum on everything else.
Neither one is a personality test. The useful one is the one you’ll still be doing when the novelty wears off. A card balance, if that’s the loud debt: How do I even pay off a credit card?.
Avalanche means highest interest rate first
List the rates. The expensive one gets the extra dollars. Over time this usually means less interest paid, because the costly debt shrinks sooner. It can feel slow if that expensive debt is also the big one. Maths-friendly. Patience required.
Snowball means smallest balance first
You clear a small balance, then roll that payment onto the next smallest. You might pay a bit more interest than avalanche. The early win helps some people stay in the game. If that’s what keeps you paying, it’s a solid pick, not a lesser one.
Minimums still matter
Whichever style you choose, minimums (or the repayment in the contract) keep every account current. Skipping one to “focus” on another can mean fees and a messier month. Autopay the minimums, then aim any extra on purpose at the debt you picked.
The same two paths show up on personal loans. Good enough is a plan you keep: Personal loans: what “good enough” payoff looks like.
No shame, and still a life
A balance isn’t a vibe fail. Name the debts, pick a method, and leave room for Friday if you can. A plan that cancels your whole life usually snaps. A plan you can live with lasts. The week map: What even is a budget?. The no-lecture version of owing: Owing money isn’t a vibe fail.
What this pick is not
It isn’t a reason to open a new loan. It isn’t a ranking of banks or cards. And HELP/HECS isn’t a card. Don’t run a study loan through avalanche or snowball like a store account. That system has its own income line: What even is the HECS repayment threshold?.
Several high-interest balances and one repayment sounds tempting? That’s a different decision, with fees and traps of its own: What even is debt consolidation?.
