If you have ever googled "how to pay off debt", you have met the two celebrities of personal finance: the avalanche and the snowball. Both work. They just work on different parts of you.
The contenders
- Avalanche — pay minimums on everything, throw every spare rand at the debt with the highest interest rate. Mathematically optimal. You pay the least total interest.
- Snowball — pay minimums on everything, attack the smallest balance first. When it dies, roll its payment into the next smallest. Psychologically optimal. You feel wins early.
A real-world example
Take a fairly typical debt load for a young professional:
- Credit card: R28,000 at 21%
- Personal loan: R45,000 at 24%
- Store account: R7,000 at 23%
- Overdraft: R5,000 at 19%
With R3,500 a month beyond minimums, the avalanche (personal loan first) saves roughly R6,000 in interest versus the snowball, and finishes about two months sooner. That is real money — but it is not life-changing money.
What is life-changing is actually finishing. And here the snowball has a dirty secret advantage: killing that R5,000 overdraft in six weeks feels incredible. Momentum is a financial instrument.
Our honest recommendation
- If your rates are wildly different — say a 28% store card next to a 12% car loan — respect the maths and go avalanche.
- If your rates are within a few points of each other, go snowball and buy yourself the motivation.
- Whichever you pick, automate the attack payment the day after payday. A strategy that depends on month-end willpower is not a strategy, it is a wish.
The rule that beats both
Never, ever finance a lifestyle upgrade while you are attacking debt. The avalanche and the snowball both melt in front of a new car payment.
The best payoff method is the one still running in month nine.
