Debt Snowball vs Avalanche: Which Pays Off Debt Faster?
Both methods throw every spare dollar at one card while paying minimums on the rest — they only differ in which card you attack first. One saves the most money; the other keeps you motivated. Here's how to choose.
Smallest balance first
Pay the smallest balance first, regardless of APR. When it's gone, roll its payment onto the next-smallest.
- Pro: fast, visible wins keep you motivated
- Pro: frees up minimum payments quickly
- Con: usually costs a little more interest
Highest APR first
Pay the highest-APR card first, regardless of balance. When it's gone, roll its payment onto the next-highest rate.
- Pro: least total interest — always
- Pro: clears the debt soonest, mathematically
- Con: the first win can take longer
A worked example
Say you have three cards and $600/month to put toward them: $1,200 at 29%, $3,000 at 22%, and $5,000 at 27%.
| Method | First card paid | Total interest | Time to debt-free |
|---|---|---|---|
| Avalanche (29% → 27% → 22%) | $1,200 @ 29% | Lowest | Shortest |
| Snowball (smallest → largest) | $1,200 (also smallest) | A bit higher | Slightly longer |
Here the smallest balance ($1,200) also happens to carry the highest APR (29%), so the two methods start the same — a common case where the gap is tiny. When your biggest balance has the highest rate, the avalanche's advantage grows. The exact numbers depend on your cards, which is why it's worth running both.
So which should you pick?
If you're disciplined and want to save every dollar, run the avalanche — it's optimal by the math. If you've struggled to stay motivated, the snowball's quick wins are worth a few extra dollars of interest. And if the two are close (they often are), pick the one you'll actually stick with. The biggest mistake isn't choosing the "wrong" method — it's only paying minimums and never starting.

What's the difference?
Order. Snowball = smallest balance first (motivation). Avalanche = highest APR first (least interest). Both roll each paid-off payment onto the next card.
Which is better?
Avalanche saves the most on paper; snowball helps you stay motivated. If close, pick the one you'll finish.
Does the snowball really work?
Yes — the quick wins help many people stay on track, at the cost of slightly more interest than the avalanche.
How much more does it cost?
Usually tens to a few hundred dollars for typical card debt — try both with our snowball calculator.
