Debt Snowball vs Avalanche — Which Strategy Is Right for You?
There are two popular strategies for paying off debt, and choosing the right one depends on your mindset and goals.
Snowball Method (Best for Motivation)
Pay off your smallest balance first regardless of interest rate. Once that debt is cleared roll its payment into the next smallest. This gives you quick wins and keeps motivation high — ideal if you need momentum to stay on track.
Avalanche Method (Best for Saving Money)
Pay off your highest interest rate debt first. This minimises total interest paid and gets you debt free faster financially. It requires more discipline since high rate debts aren’t always the smallest — but it costs you less overall.
So Which Is Better?
The avalanche method saves more money. The snowball method keeps more people on track. The best strategy is the one you’ll actually stick to. Many people start with snowball to build confidence then switch to avalanche once the habit is established.
The Truth:
The best strategy is the one you’ll actually stick to.
Even if avalanche saves more money, it won’t work if you lose motivation and stop.
Pro Tip
Many people combine both:
- Start with snowball to build momentum
- Then switch to avalanche to save money
Example
If you have $10,000 in debt at 18% interest and pay $300/month, it could take several years to repay. Adding just $50 extra per month can significantly reduce both the payoff time and total interest paid.
Tips to Pay Off Debt Faster
Make extra payments — even $25-50 extra per month significantly reduces your timeline and total interest. Use the extra payment field to see the exact impact.
Use windfalls — tax refunds, bonuses and unexpected income should go straight to debt before lifestyle spending.
Cut one expense — cancelling unused subscriptions or reducing dining out by one meal per week can free up $50-100/month for debt repayment.
Avoid adding new debt — every new purchase on credit while paying off existing debt extends your timeline.
FAQs
What is the debt snowball method?
The snowball method means paying off your smallest debt first while making minimum payments on all others. When the smallest is paid off you roll that payment into the next smallest. The quick wins build momentum and motivation.
What is the debt avalanche method?
The avalanche method means targeting your highest interest rate debt first. This minimises the total interest you pay and gets you debt free faster overall — but requires more patience since high rate debts aren’t always small.
How much extra should I pay each month?
Any extra amount helps. Even $25-50 per month on a $10,000 debt can save hundreds in interest and cut months off your timeline. Use the extra payment field in the calculator to see exactly what your situation looks like.
Should I pay off debt or save money first?
For high interest debt (above 7-8%) pay it off first — the interest cost exceeds most investment returns. For low interest debt like a mortgage below 4% it can make sense to invest and pay the minimum. Always maintain a small emergency fund before aggressively paying down debt.
What if I can only make minimum payments?
Minimum payments keep you in debt much longer and cost significantly more in interest. Even a small increase above the minimum makes a big difference. Use the calculator to see exactly how much each extra dollar saves you.
