Debt can feel like an invisible weight—always there, yet hard to pin down. But if you follow a clear system, you can gradually shed that burden. Two methods have proven effective: the snowball method and the avalanche method. Both aim for the same goal but take different approaches. Which one is right for you depends on more than just the numbers. Let’s take a look.
Debt in Germany – a widespread problem
Financial difficulties and debt affect a significant portion of the population in Germany. According to the Debt Atlas published by the credit reporting agency Creditreform, approximately 5.67 million individuals in Germany were over-indebted in 2025—equivalent to an over-indebtedness rate of 8.09% of all adults. Those particularly affected include young adults, single parents, and people who have experienced an unexpected drop in income.
The most common forms of personal debt are overdrafts, credit card debt, and installment loans—often several of these at the same time. It is precisely this combination that serves as the starting point for this article. The good news: Anyone who knows their debts, has a monthly repayment budget, and follows a clear strategy can resolve their debt problem within a reasonable amount of time.
The two most popular strategies for doing so are called the snowball and the avalanche.
The Snowball Method – Small Wins, Big Impact
How the method works
The snowball method was largely popularized by American financial advisor Dave Ramsey, who made it a core component of his “Baby Steps” program. While the underlying idea of paying off small debts first had existed before, Ramsey established the method as a distinct, named system and spread it to millions of people.
The principle is incredibly simple: You pay off the smallest debt first—regardless of the interest rate. Once that’s paid off, you roll the freed-up budget into the next-largest debt. Like a snowball rolling downhill and getting bigger and bigger.
Schritt-für-Schritt-Anleitung
- List all debts—including current balance, interest rate, and minimum payment.
- Sort by amount—the smallest debt goes at the top.
- Pay the minimum payments – on all debts except the smallest one.
- Allocate the entire additional budget – (after paying the minimum payments) – to the smallest debt.
- Once that debt is paid off: Apply the freed-up amount (minimum payment + additional budget) to the next debt.
- Repeat until all debts are paid off.
| Advantages | Disadvantages |
|---|---|
| Quick initial sense of achievement | Potentially higher total interest costs |
| High motivation due to visible progress | Ignores the interest rate as a factor for optimization |
| Psychologically sustainable | May be mathematically less efficient |
| Easy to understand and implement | Works less effectively when all debts are of similar size |
The Avalanche Method – Mathematically Optimized
How the method works
The snowball method follows simple interest logic: you pay off the debt with the highest interest rate first. This minimizes the total interest costs over the entire term. The image of an avalanche symbolizes the momentum you gain by eliminating the most expensive loan first.
Step-by-step instructions
- List all debts—including current balance, interest rate, and minimum payment.
- Sort by interest rate—the debt with the highest interest rate goes at the top.
- Pay the minimum amounts – on all debts except the most expensive one.
- Allocate the entire additional budget – to the debt with the highest interest rate.
- Once that is paid off: redirect the budget to the debt with the next-highest interest rate.
- Repeat until all debts are paid off.
| Advantages | Disadvantages |
|---|---|
| Minimal total interest costs | It may take a long time to see initial results |
| Mathematically optimal strategy | Requires a high tolerance for frustration |
| Shortest total duration for the same budget | May fail if motivation is lacking |
| Ideal for rational, disciplined individuals | WLess intuitive for beginners |
Snowball vs. Avalanche – A Direct Comparison with a Sample Calculation
Let’s consider a specific scenario that reflects the situation in many households:
Background
| Debt | Amount | Interest Rate (p.a.) | Minimum payment (estimated) |
|---|---|---|---|
| Credit card | 2,500 euros | 19% | approx. 50 euros |
| Overdraft | 1,200 euros | 12% | approx. 30 euros |
| Installment loan | 8,000 euros | 7% | approx. 150 euros |
| Total | 11,700 euros | – | approx. 230 euros |
Available monthly budget based on minimum payments: 400 euros
This means: 230 euros in minimum payments + 170 euros in additional budget = 400 euros in total monthly payments.
Option A: Snowball Order
Ordered by amount (ascending):
- Overdraft: 1,200 euros
- Credit card: 2,500 euros
- Installment loan: 8,000 euros
The overdraft amount of 1,200 euros is repaid with a minimum payment of 30 euros plus an additional 170 euros, totaling 200 euros per month. At 12% p.a. (1% monthly interest), it is fully paid off after exactly seven months (interest costs: 43.86 euros). During this time, the credit card (50 euros per month) and installment loan (150 euros per month) continue to be paid at the minimum amount.
Afterward, the freed-up 200 euros are allocated to the credit card, so that it receives 220 euros per month. By the end of Phase 1, the credit card balance has dropped to 2,423.53 euros and is paid off in another 13 months at 19% p.a. (interest costs for Phase 2: 260.98 euros).
Finally, the entire budget of 400 euros goes toward the installment loan, which at this point still amounts to 5,814.70 euros, and is paid off in 16 additional months.
Total term (compound interest): 36 months (3 years)
Total interest cost (compound interest): €1,672.40
Option B: Avalanche Order
Sorted by interest rate (descending):
- Credit card: 2,500 euros / 19%
- Overdraft: 1,200 euros / 12%
- Installment loan: 8,000 euros / 7%
The additional budget of 170 euros is immediately added to the credit card (50 euros minimum + 170 euros = 220 euros per month). The credit card with a 2,500-euro balance at 19% per annum (1.5833% monthly interest) is paid off after exactly 13 months (interest costs: 278.31 euros). At the same time, the overdraft account pays a minimum installment of 30 euros and the installment loan pays a minimum installment of 150 euros.
Afterward: The 220-euro budget goes toward the overdraft, which still amounts to 951.43 euros after Phase 1—this is paid off in five additional months. Then the entire 400-euro budget goes toward the installment loan, which at this point still amounts to 6,044.84 euros and is paid off in 16 additional months.
Total term (snowball method): 34 months (just under 3 years)
Total interest costs (snowball method): €1,494.70
What the comparison shows
In this example, the avalanche method saves exactly 177.70 euros in interest costs (1,672.40 vs. 1,494.70 euros). The total term is two months shorter with the avalanche approach (34 instead of 36 months). The real difference lies less in the math and more in the psychology: With the snowball method, you’ve completely paid off the first debt after about six months. With the avalanche method, it takes longer before you can check off the first one.
Note: The loan terms and interest costs listed are approximate figures based on a simplified calculation. For accurate planning, we recommend using a loan repayment calculator or consulting a professional.
The Psychology Behind It – Motivation vs. Rationality
People in debt aren’t just battling interest rates. They’re also battling frustration, exhaustion, and the inner urge to give up. This is precisely where the two methods diverge. Behavioral economic research shows that people remain significantly more motivated by achievable intermediate goals than by abstract overall goals. In 2011, Amar, Ariely, Ayal, Cryder, and Rick demonstrated in a series of experiments published in the Journal of Marketing Research that debtors systematically tend to pay off the smallest debt first—regardless of the interest rate. The researchers call this behavior “debt account aversion”: the psychological burden of having multiple outstanding debts is greater than the rational drive to optimize interest payments. This speaks in favor of the snowball method: Anyone who can cross a debt off the list after seven months experiences a noticeable boost in motivation.
The avalanche method, on the other hand, works well for people who think more analytically, value numbers, and can work with a clear end date in mind. Those who know that following a specific order will leave them with 300 euros more in their pocket find motivation in that figure alone. The risk with the avalanche approach: If the first debt is too large and progress remains invisible for a long time, the dropout rate increases. A theoretically superior method that isn’t stuck with is worse than a slightly less efficient one that actually works.
Which method is best suited for whom?
The following overview provides a general guide—it is not a substitute for individual consultation:
“Snowball” might be a better fit if you…
- have frequently given up on plans in the past
- need quick successes to stay on track
- have many small debts piling up
- have an emotional connection to “checked-off” to-do lists
Avalanche might be a better fit if you…
- take a disciplined and analytical approach
- want to keep total costs as low as possible
- have almost paid off your smallest debt anyway
- are comfortable with a long-term time horizon
The hybrid approach – the best of both worlds
If you don’t want to commit to one method, you can combine both. One possible approach:
- Start with the snowball method to quickly pay off the first, smallest debt and build momentum.
- Then switch to the avalanche method once you’ve achieved your first success and your motivation is solid.
The hybrid approach isn’t a compromise, but a pragmatic decision: You leverage the psychological boost of the snowball effect and the financial efficiency of the avalanche method.
5 Common Mistakes When Paying Off Debt
1. No emergency fund
If you don’t have a financial cushion, the next unexpected expense will immediately plunge you back into debt. Before you start making aggressive payments, you should have a financial cushion in place. If you’re in the process of paying off debt but haven’t reached that goal yet, you should at least ensure you have a minimum buffer of 1,000 euros before directing your entire extra budget toward debt repayment.
2. Taking on new debt at the same time
Even the best repayment strategy falls apart if you’re simultaneously accumulating new credit card debt or installment payments. Credit card reserves, setting up standing orders instead of credit card payments, and a clear monthly budget can help.
3. Ignoring or forgetting minimum payments
If you forget even a single minimum payment, you risk late fees, worse terms, and negative credit bureau entries. Set up standing orders.
4. Not putting your repayment plan in writing
A mental plan is no plan at all. A simple spreadsheet or note-taking app is sufficient.
5. Not checking interest rates regularly
Terms and conditions change. It may be worth replacing high-interest debt with more affordable loans through debt consolidation. As of March 2026, the effective interest rates for consumer loans for customers with strong credit ratings average around 6.19% p.a. – significantly lower than the 19% of a typical credit card limit or the overdraft interest rate, which is often 12 to 15%.
