How to pay off debt faster: avalanche vs snowball explained

📅 April 2026⏱ 4 min read🏷 Debt

The fastest way to pay off debt is to pay minimums on everything except one target debt — and throw every spare dollar at that target. The two main methods differ only in which debt you target first.

The two strategies

🔺 Avalanche Method (mathematically optimal)

Pay minimums on all debts. Put all extra money toward the highest interest rate debt first. Once paid off, roll that payment into the next highest rate. Repeat.

Minimises total interest paid
Fastest total payoff in most cases
Best if you have high-rate debt (credit cards, payday loans)
Can feel slow if your highest-rate debt is also your largest balance

❄️ Snowball Method (psychologically effective)

Pay minimums on all debts. Put all extra money toward the smallest balance debt first. Once paid off, roll that payment into the next smallest. Repeat.

Provides early wins to maintain motivation
Reduces the number of open accounts quickly
May pay more total interest than avalanche
Research shows higher completion rates among people who struggle with consistency

Which is better? Mathematically, avalanche. Behaviourally, whichever one you'll actually stick to. A person who completes the snowball plan beats someone who starts the avalanche and quits in month 4.

Finding extra money to accelerate payoff

The single biggest lever is increasing the amount you throw at your target debt. Even an extra $50/month makes a significant difference on most debts. Options to find extra money:

Windfall rule: Put 50–100% of any bonus, tax refund, or unexpected income directly onto debt
Temporary cuts: Identify 1–2 subscriptions or habits to pause until the highest-rate debt is gone
Balance transfers: Moving high-rate credit card debt to a 0% introductory rate card buys 12–18 months of interest-free payoff time
Negotiate lower rates: Call your credit card issuer and ask for a lower rate — it works more often than people expect

The minimum payment trap

Paying only minimums on credit card debt is designed to maximise the bank's profit. On a $5,000 balance at 20% interest, minimum payments of ~$100/month take 8+ years to clear the debt and cost over $4,000 in interest alone — nearly doubling the original balance. Even paying $200/month instead of $100 cuts the timeline to under 3 years and saves $2,500.
