Snowball vs. Avalanche Calculator
Compare two proven payoff orders across up to three balances using the same monthly budget.
01
What both strategies share
List each balance, APR, and minimum payment. Continue every required minimum, then direct the same extra monthly amount to one target. When that debt is paid, roll its former payment into the next target. The strategy changes the order—not the total amount available each month.
Before accelerating unsecured debt, make sure essential bills and minimums remain current. A small cash buffer may prevent the next unexpected expense from returning to a credit card.
02
Avalanche: highest rate first
The avalanche targets the active debt with the highest APR. Because expensive balances are reduced sooner, this order is mathematically designed to reduce total interest when the monthly budget and payment behavior are otherwise identical.
Its disadvantage is emotional rather than mathematical. If the highest-rate balance is large, the first account may remain open for a long time, making progress less visible.
03
Snowball: smallest balance first
The snowball targets the smallest current balance regardless of APR. Closing a small account can create a quick milestone and release its minimum payment into the next target.
The possible cost is additional interest when a larger high-rate balance waits. The right question is not whether motivation matters—it does—but how much the motivational preference costs in the specific debt list. A comparator makes that tradeoff visible.
WORKED EXAMPLE
Put it into practice
If avalanche saves $202 but both methods finish in nearly the same month, someone may reasonably choose either. If the interest difference is several thousand dollars, the cost of choosing snowball deserves more weight.
ACTION PLAN
What to do next
- Stop adding new charges where possible.
- Record balances, APRs, and minimums from statements.
- Choose an extra amount that can be sustained.
- Automate minimums and send extra to the current target.
FAQ
Common questions
Can I switch methods?
Yes. Recalculate after a balance, rate, or available payment changes.
What about a 0% promotional balance?
Include the expiration date in your decision. A future rate change is not captured by a fixed-APR model.
