DESTROY YOUR DEBT.
Compare avalanche vs snowball on the extra cash left after Reality Standard net—not on the offer letter.
The short version
Extra payoff dollars only exist after Reality Standard net. Avalanche hits the highest APR first; snowball clears the smallest balance for a faster first win.

Avalanche AdvantageOPTIMAL
By targeting the highest APR first, you pay the absolute minimum in total interest. This is the mathematically superior choice for wealth building.
Avalanche vs snowball (same extra $120)
Illustration from the tool notes: $2,100 card at 24% APR and $6,800 loan at 11% APR, with $120 extra after minimums. Not a payoff guarantee.
| Method | Extra cash hits | Why people pick it |
|---|---|---|
| Avalanche | Highest APR first (the 24% card) | Usually less total interest |
| Snowball | Smallest balance first ($2,100 card) | Faster first $0 for momentum |

Why extra dollars only work on net
Minimum payments are designed to cover most of the interest plus a sliver of principal. An extra $50 only exists if it survived FICA and withholding. Plan that surplus from the salary leftover—not from gross.

- Enter any extra monthly amount you can put toward payoff.
- Compare snowball vs avalanche timelines and total interest paid.
- Use the faster plan that matches your motivation and cash flow.
$8,400 credit card at 22% APR
A $8,400 balance at 22% APR with a $168 minimum (~2%) takes about 7 years and $3,600+ in interest if you pay only the minimum. Adding $150/month extra clears the debt in roughly 2.5 years and saves over $2,500 in interest—exact months depend on how your issuer applies payments.
Two debts: $2,100 card + $6,800 personal loan
Suppose a $2,100 card at 24% APR ($42 minimum) and a $6,800 personal loan at 11% APR ($145 minimum), with $120/month extra available. Avalanche sends the extra to the 24% card first—roughly 18 months to clear both and about $1,450 total interest in this illustration. Snowball clears the smaller card in ~8 months for a quicker win but may add a bit more interest overall.
Limitations
- Assumes fixed APR and on-time payments—penalty rates and fees are not modeled.
- Minimum payment rules vary by lender; real statements may differ from estimates.
- Not credit counseling or financial advice—talk to your issuer or a nonprofit counselor for a personalized plan.
Frequently Asked Questions
- What is the debt snowball method?
- Pay off the smallest balance first for quick wins and momentum, even if another debt charges more interest.
- What is the debt avalanche method?
- Send every extra dollar to the highest-interest debt first—that is how you pay the least interest over time.
- Why are minimum payments dangerous?
- Minimums mostly cover interest, so your balance barely shrinks and you stay in debt far longer than you expected.
