The debt avalanche method is a highly efficient debt repayment strategy that prioritises debts with the highest interest rates, helping you save money and become debt-free more quickly. By focusing on interest rather than balance size, this method directly targets the most costly debts first—making it a smart move for those aiming to minimise interest and accelerate payoff.
Why Choose the Debt Avalanche Method?
1. Maximum Interest Savings
By attacking high-interest debts first, you significantly reduce the amount of interest paid over time. This mathematical efficiency is a core advantage of the avalanche method.
2. Faster Debt Resolution
Paying down the costliest debt releases more funds to address subsequent debts, potentially shortening your overall debt-free timeline.
3. Structured and Strategic
The method’s systematic framework—list, prioritise, execute—provides a clear roadmap to financial control.
Step‑by‑Step: How to Use the Debt Avalanche Method
Step 1: List All Debts by Interest Rate
Create a list of all your debts—credit cards, loans, medical bills—ranked from highest to lowest interest rate.
Step 2: Make Minimum Payments Across All Debts
Ensure all debts receive at least their minimum payments to avoid penalties or late fees.
Step 3: Allocate Extra Funds to Highest-Interest Debt
Any surplus—income increases, budget savings, bonuses—should go entirely toward the debt with the highest interest rate until it’s fully paid.
Step 4: Roll Over Payments
After the highest-interest debt is eliminated, combine its payment (minimum + extra) with the minimum of the next-HIGH-APR debt. Continue this “avalanche” until debts are gone.
Step 5: Track Progress and Adjust
Monitor your repayment progress. If interest rates change or promotional periods end, reorder your list to stay optimised.
Real‑World Example
Let’s say you have:
- Debt A: £4,000 at 20% APR — Minimum £100
- Debt B: £6,000 at 15% APR — Minimum £150
- Debt C: £2,000 at 8% APR — Minimum £50
- Extra to allocate: £200/month
Payment Flow:
- Pay minimums on all (total £300).
- Add £200 extra to Debt A (highest APR): total payment £300/month → Debt A cleared first.
- Roll over funds to Debt B: £150 + £300 = £450/month.
- After Debt B clears, move £450 toward Debt C’s payments.
This yields faster payoff and significant interest savings.

What Users Say
Reddit users offer simpler analogies and comparisons:
“It’s just a fancy term for general commonsense… paying the minimums on all of your debts and using anything extra to pay down the debt with the highest interest rate.”
“Avalanche is mathematically better… but more people are successful using snowball. Some things are more than math.”

- Celebrate milestones, even small ones, to stay motivated.
- Adjust approach if needed—for those who need quick wins, consider mixing with snowball or using motivational triggers.
- Use tools and apps like budget planners or payoff calculators to visualise progress.
