Snowball vs. Avalanche
We recommend the Debt Snowball for most people.
Debt Avalanche usually wins the spreadsheet: with the same monthly payment budget, attacking the highest APR first generally minimizes interest. Debt Snowball optimizes for something the spreadsheet does not capture directly—visible progress. You close smaller accounts sooner, reduce the number of debts competing for your attention, and roll each freed payment into the next target.

A plan you follow can be better than a mathematically optimal plan you abandon.
That is why Snowball is our default recommendation. It deliberately prioritizes discrete wins rather than minimizing every dollar of interest. We still calculate Avalanche beside it so you can see exactly what that choice costs for your own debts.
This is a behavioral recommendation, not a guarantee. If one debt has a dramatically higher APR, or you know interest minimization is what keeps you motivated, Avalanche can be the better fit.
Debt Snowball
RecommendedPay required minimums on every debt, then direct the rest of your fixed monthly debt budget to the smallest remaining balance.
- Optimizes for: account closures and visible progress.
- First target: smallest balance.
- Primary tradeoff: may cost more interest than Avalanche.
- Best fit: people who benefit from shorter milestones or have struggled to sustain a payoff plan.
Debt Avalanche
Pay required minimums on every debt, then direct the rest of the same monthly budget to the highest-APR remaining debt.
- Optimizes for: lowest interest cost under consistent assumptions.
- First target: highest APR.
- Primary tradeoff: the first visible payoff can take longer.
- Best fit: people whose strongest motivator is minimizing interest, especially when APR differences are large.
Why we take the behavioral side seriously
Research on consumer debt management has found that the fraction of accounts closed was predictive of successfully eliminating debt, even after accounting for the amount of debt paid down. The researchers argued that completing discrete subtasks can help people persist toward a larger goal.
Separate experimental research on “small victories” found that people completed an unpleasant multi-part task faster when the parts were ordered from smallest to largest. These studies do not prove that Snowball will outperform Avalanche for every borrower, but they do support the idea that progress markers and task structure can affect persistence.
The fair comparison uses the same monthly budget
Our calculator holds the Snowball and Avalanche monthly debt budget constant. The only thing that changes is which active debt receives the extra payment. That isolates the effect of payoff order instead of giving one strategy more money than the other.
The result gives you two useful numbers at once: how much Avalanche would save in interest, and what Snowball's earlier balance-first milestones cost. You can then decide whether that interest difference is worth paying for a plan structured around visible wins.
When we would choose Avalanche instead
- One debt has an APR far above the others, making the interest penalty for delaying it unusually large.
- You have a strong history of following long financial plans without needing early milestones.
- Seeing the interest total fall is more motivating to you than closing individual accounts.
- Your calculator result shows a Snowball interest premium that you are not comfortable paying.
