Avalanche vs Snowball Method – Which Debt Repayment Strategy Is Better?

When you are juggling multiple debts – a credit card, a cash loan, an installment plan – a critical question arises: in what order should you pay them off? The two most popular strategies are the avalanche method and the snowball method. Both have their advocates, both work, but they differ in approach, psychology, and financial efficiency.

What Is the Avalanche Method?

The debt avalanche method is a purely mathematical approach. The principle is straightforward:

  1. Pay the minimum installment on all obligations
  2. Direct every extra złoty toward the debt with the highest interest rate
  3. Once that debt is paid off, move to the next most expensive one
  4. Repeat until everything is cleared

Example

Suppose you have three debts:

Debt Balance Interest Rate Minimum Payment
Credit card 8,000 PLN 21% 200 PLN
Installment loan 15,000 PLN 12% 450 PLN
Cash loan 5,000 PLN 8% 250 PLN

With the avalanche method, your entire surplus goes to the credit card (21%), even though the cash loan (5,000 PLN) is smaller and would be quicker to eliminate.

Advantages

  • You save the most on interest – the mathematically optimal solution
  • You pay off all debt faster – less money is consumed by interest charges
  • Rational approach – driven by numbers, not emotions

Disadvantages

  • No quick wins – the first debt might be the largest, so repayment takes months
  • Requires strong motivation – results become visible only after a longer period
  • Psychologically harder – easy to get discouraged

What Is the Snowball Method?

The debt snowball method, popularized by Dave Ramsey, focuses on psychology and motivation:

  1. Pay the minimum installment on all obligations
  2. Direct every extra złoty toward the smallest debt
  3. Once that debt is paid off, roll the freed-up payment into the next smallest debt
  4. The "snowball" grows with each debt eliminated

Example (Same Debts)

With the snowball method, you first tackle the cash loan (5,000 PLN), even though it has the lowest interest rate (8%). After paying it off, you add the freed 250 PLN to the payment on the next debt.

Advantages

  • Quick wins are motivating – the first debt disappears relatively fast
  • Psychological payoff – each eliminated debt is a tangible success
  • Simpler system – sort by balance from smallest to largest; no need to compare rates
  • Fewer obligations = less stress – you reduce the number of creditors

Disadvantages

  • You pay more in total interest – interest rates are ignored
  • Longer overall repayment time – compared to the avalanche
  • Mathematically suboptimal – emotions win over calculation

Head-to-Head: Avalanche vs Snowball in Numbers

Let us take a concrete example from the Polish context. Assume you have a total of 40,000 PLN in debt and can allocate 2,000 PLN per month to repayment:

Scenario

Debt Balance RRSO Min. Payment
Payday loan (in installments) 3,000 PLN 180% 300 PLN
Credit card 12,000 PLN 22% 360 PLN
Cash loan 10,000 PLN 11% 400 PLN
Installment loan 15,000 PLN 9% 500 PLN

Surplus: 2,000 PLN – 1,560 PLN (sum of minimum payments) = 440 PLN

Avalanche Order: Payday → Credit Card → Cash Loan → Installment

In this scenario, both methods would start with the payday loan (highest rate and smallest balance). But after clearing it, the avalanche directs the surplus to the credit card (22% RRSO), maximizing interest savings.

With more varied amounts and rates, the difference can reach several thousand złotys in favor of the avalanche.

When Is the Difference Greatest?

  • The larger the spread in interest rates (e.g., payday loan at 180% vs mortgage at 5%), the more the avalanche pays off
  • The more similar the rates, the smaller the gap – and the more justified the snowball becomes

Which Method Is Right for You?

Choose the Avalanche If:

  • You are analytical and motivated by numbers
  • You have strong financial self-control
  • Your debts have very different interest rates (e.g., payday loan + mortgage)
  • You want to save as much money as possible
  • You do not need quick wins to stay motivated

Choose the Snowball If:

  • You need quick successes to maintain momentum
  • You have many small debts that feel overwhelming
  • The stress from the number of creditors is worse than the cost of interest
  • Your interest rates are similar (the difference is not dramatic)
  • You have tried paying off debt before and gave up

Or Try a Hybrid Approach

You do not have to choose rigidly. Many financial experts suggest combining both methods:

  1. Start with the snowball – pay off 1-2 smallest debts for a quick sense of achievement
  2. Switch to the avalanche – direct further payments by interest rate
  3. If motivation drops, return to the snowball temporarily

This approach combines the psychological benefits of the snowball with the mathematical efficiency of the avalanche.

Polish Context: What to Consider

RRSO – Your Best Friend

In Poland, financial institutions are required to disclose the RRSO (Rzeczywista Roczna Stopa Oprocentowania – the real annual percentage rate), which includes not only interest but also commissions and fees. Always compare RRSO, not the nominal interest rate.

Payday Loans (Chwilówki) – Always Priority

If you have a payday loan, pay it off first regardless of your chosen method. RRSO on payday loans in Poland can reach several hundred or even several thousand percent. One month of delay can cost more than a year of interest on a regular bank loan.

Credit Cards – The Hidden Predator

Credit cards in Poland typically carry 18-22% RRSO. If you are paying only minimums, you may never pay off the card – the minimum payment often covers mostly interest.

Mortgages – A Different World

A mortgage is usually not included in the avalanche/snowball strategy. It has low interest, is secured by real estate, and has a multi-year horizon. Focus on more expensive obligations.

Tools for Planning Repayment

To effectively apply either method, you need progress tracking. Freenance lets you monitor your obligations and visualize repayment progress, which is essential regardless of your chosen strategy.

What to Track

  • Current balance of each debt
  • Total interest paid
  • Projected payoff date for each obligation
  • Total debt-freedom date

Regular Updates

It is worth updating your repayment table monthly. This not only helps with planning but also provides a sense of progress – seeing declining balances is incredibly motivating.

What Does Research Say?

Studies published in the Harvard Business Review (Remi Trudel et al.) found that people using the snowball method were more likely to pay off their debts entirely than those using the avalanche. Why? Because the motivation from quick wins turned out to be more important than interest savings.

Another interesting finding is that simply starting repayment (regardless of method) matters more than choosing the "perfect" strategy. The worst strategy is the one you do not follow.

Frequently Asked Questions

Can I Switch Methods Midway?

Yes. There is nothing wrong with switching from avalanche to snowball (or vice versa) if you feel the current strategy is not working. What matters is that you keep paying down debt.

What If I Have Only One Debt?

Then the choice of method is irrelevant – direct all surpluses toward that single debt.

Should I Invest Instead of Overpaying Debt?

Rule of thumb: if your debt's interest rate is higher than the expected return on investment (historically 7-10% per year in the stock market), pay off the debt. Payday loans and credit cards – always pay off first.

What About Student Loans?

Polish student loans carry very low interest rates (often below 2%). In your repayment strategy, they should be at the very bottom of the priority list.

Summary

Criterion Avalanche Method Snowball Method
Interest savings ✅ Greater ❌ Lower
Total repayment speed ✅ Faster ❌ Slower
Motivation ❌ Requires discipline ✅ Quick wins
Simplicity ❌ Must compare RRSO ✅ Sort by amount
Effectiveness (research) ❌ More dropouts ✅ More completions

The best method is the one you will stick with. If you are disciplined and analytical – choose the avalanche. If you need motivation and quick successes – choose the snowball. And if you are unsure – start with the snowball and switch to the avalanche once you build momentum.
