Quick Answer: Which Method Wins?

• Avalanche saves more money (always)
• Snowball provides faster psychological wins (usually)
• Most people succeed with Snowball (behaviorally)
• Disciplined savers should use Avalanche (mathematically)

Use our calculator to see your personal savings difference.

What is the Debt Avalanche Method?

The avalanche method attacks debts by interest rate, highest to lowest. It's mathematically optimal, minimizing total interest paid.

Avalanche Example:

You have $1,000 monthly for debt payments:

1. Credit Card A: $5,000 at 24.99% APR (minimum: $100)
2. Credit Card B: $3,000 at 18.99% APR (minimum: $60)
3. Car Loan: $15,000 at 5.99% APR (minimum: $350)
4. Student Loan: $25,000 at 4.53% APR (minimum: $280)

Avalanche Order: Pay minimums on all, then put extra $210 toward Credit Card A (highest rate).

What is the Debt Snowball Method?

The snowball method attacks debts by balance, smallest to largest. It's psychologically motivating, providing quick wins.

Snowball Example:

Same debts, same $1,000 monthly:

1. Credit Card B: $3,000 (smallest balance)
2. Credit Card A: $5,000
3. Car Loan: $15,000
4. Student Loan: $25,000 (largest balance)

Snowball Order: Pay minimums on all, then put extra $210 toward Credit Card B (smallest balance).

Real Savings Comparison

Using our example debts with $1,000 monthly payments:

Avalanche Method Results:

• Total Interest Paid: $8,432
• Time to Debt Freedom: 61 months
• First Debt Eliminated: Month 16

Snowball Method Results:

• Total Interest Paid: $9,887
• Time to Debt Freedom: 62 months
• First Debt Eliminated: Month 11

Avalanche Saves: $1,455 in this scenario.

When to Use Debt Avalanche

Choose avalanche if you:

• Have strong financial discipline
• Are motivated by math, not emotion
• Can delay gratification
• Have high-interest debt (20%+ APR)
• Want optimal financial results

Avalanche Success Story:

"I had $45,000 in debt across 6 cards. Using avalanche, I saved $3,200 in interest and paid everything off 8 months faster than snowball would have." - Sarah, 34

When to Use Debt Snowball

Choose snowball if you:

• Need motivation boosts
• Have many small debts
• Struggle with consistency
• Value psychological wins
• Have similar interest rates across debts

Snowball Success Story:

"Paying off my first $500 debt in 2 months kept me going. I stuck with it and cleared $30,000 in 3 years. Avalanche might have saved money, but I would have quit." - Mike, 28

The Hybrid Approach

Some combine both methods:

1. Snowball Starter: Pay off 1-2 small debts for motivation
2. Avalanche Finish: Switch to highest rates for remaining debts
3. Best of Both: Quick wins plus interest savings

Our calculator lets you model hybrid approaches.

Factors That Impact Your Choice

1. Interest Rate Spread

• Large spread (5%+ difference): Avalanche saves significantly
• Small spread (<3% difference): Snowball's motivation might win

2. Balance Distribution

• Many small debts: Snowball provides quick wins
• Few large debts: Avalanche often better

3. Extra Payment Amount

• Large extra payments: Avalanche maximizes savings
• Small extra payments: Snowball's psychology crucial

4. Personal Psychology

• Numbers-motivated: Avalanche
• Progress-motivated: Snowball

Common Debt Payoff Mistakes

Mistake 1: Not Having an Emergency Fund

Build $1,000 emergency fund before aggressive debt payoff. Without it, emergencies create new debt.

Mistake 2: Closing Paid-Off Credit Cards

Keep them open for credit history. Just stop using them.

Mistake 3: Ignoring the Root Cause

Debt payoff without budget changes leads to new debt. Track spending, cut expenses, increase income.

Mistake 4: Making Only Minimum Payments

Minimum payments barely cover interest. A $5,000 credit card at 18% APR takes 37 years paying minimums.

Accelerating Either Method

1. Increase Income

• Side hustles
• Overtime
• Sell unused items
• Tax refunds to debt

2. Reduce Expenses

• Cancel subscriptions
• Meal prep
• Generic brands
• Negotiate bills

3. Balance Transfer Cards

• 0% APR for 12-21 months
• Combines with either method
• Saves hundreds in interest
• Requires good credit

4. Debt Consolidation Loans

• Lower single interest rate
• One payment
• Fixed payoff date
• Works with both methods

The Math Behind Each Method

Avalanche Mathematics

Total Interest = Sum of (Balance × Rate × Time)

Minimizing highest Rate × Balance products first minimizes total interest.

Snowball Psychology

Completion Rate = Motivation × Consistency

Early wins increase motivation, improving long-term consistency and completion rates.

Special Situations

Multiple Debts, Same Interest Rate

Use snowball (smallest first) when rates are equal.

Variable Rate Debts

Treat current rate as fixed, but prioritize these in avalanche during rising rate environments.

Promotional Rates Expiring

Prioritize before rate increases, regardless of method.

Cosigned Debts

Consider prioritizing to protect relationships, regardless of mathematical optimization.
