Paying $1,175 a month, you’ll pay $7,146 in interest. That’s 6 years 1 month sooner and $7,671 less interest than paying only the minimums.
| Payoff order | Paid off | Interest |
|---|---|---|
| Credit card | Apr 2028 | $1,583 |
| Store card | Jun 2028 | $392 |
| Car loan | May 2029 | $1,753 |
| Student loan | Aug 2030 | $3,419 |
| Total | Aug 2030 | $7,146 |
| Compared | Debt-free | Interest |
|---|---|---|
| Avalanche (yours) | 3 years 10 months | $7,146 |
| Snowball | 3 years 10 months | $7,263 |
| Minimums onlyNo extra, and paid-off minimums stop | 9 years 11 months | $14,818 |
The snowball order would cost $117 more in interest.
Assumptions and limitsChecked Oct 24, 2026
Assumed
- Rates and minimum payments stay the same until each debt is paid off.
- No new charges are added.
- Payments are made on time each month.
Not modeled
- Minimum payments that shrink with the balance, as card minimums often do.
- Promotional rates, fees and balance transfers.
- Student loan income-driven plans and forgiveness.

How it works
Minimums, then one target
Every month each debt gets its minimum. Whatever is left of your budget goes to one target debt until it’s gone, then to the next.
Payments roll over
When a debt is paid off, its minimum keeps going toward the rest, so your monthly payment stays the same and each debt goes faster than the last.
Avalanche or snowball
Avalanche targets the highest rate and always pays the least interest. Snowball targets the smallest balance, so the first debt disappears sooner, which helps some people keep going.
