How to Pay Off Debt Faster: The Avalanche vs Snowball Method Explained
Two popular debt payoff strategies — avalanche and snowball — give very different results. One saves you more money. The other keeps more people on track. Here's how to choose.
If you have multiple debts — credit cards, a car loan, student loans — the order in which you pay them off matters more than most people realise. Two methods dominate the conversation: the avalanche and the snowball.
The Avalanche Method
Pay minimum payments on all debts. Direct every extra pound or dollar to the debt with the highest interest rate first. Once it's cleared, roll that payment into the next highest-rate debt.
Advantage: Mathematically optimal. You pay the least total interest over the life of your debts.
Disadvantage: Your highest-rate debt might also be your largest balance. Progress can feel slow before you see your first debt cleared.
The Snowball Method
Pay minimum payments on all debts. Direct every extra payment to the debt with the smallest balance first, regardless of interest rate.
Advantage: Quick wins. Clearing small debts fast creates momentum and keeps motivation high.
Disadvantage: You'll pay more in interest overall compared to the avalanche.
Which Should You Choose?
If the interest rate difference between your debts is large — say, a 22% credit card vs a 5% student loan — the avalanche saves meaningfully more money and is worth the discipline.
If the rates are similar, or if you've struggled with motivation and consistency before, the snowball's psychological wins can keep you on track long enough to see real progress.
Either method, applied consistently, beats making minimum payments indefinitely.
The Step Most People Skip
Before aggressively paying down debt, make sure you have a small emergency fund (even £500–£1,000). Without one, any unexpected expense puts you straight back on the credit card.
