Both methods direct extra money toward one debt while you maintain required payments on the others. The best choice is the one you can sustain, so compare the tradeoff, choose a method, and model it before acting.
After required payments, target the debt with the highest interest rate first. This generally minimizes interest cost when payments and other conditions stay the same.
Often fits: people motivated by mathematical efficiency who can stay engaged before the first balance disappears.
After required payments, target the smallest balance first. Early account closures can create visible momentum, though total interest may be higher.
Often fits: people who value quick milestones and need progress they can see to sustain the plan.
| Question | Avalanche | Snowball |
|---|---|---|
| First target | Highest interest rate | Smallest balance |
| Main advantage | Usually lower interest cost | Usually faster first payoff milestone |
| Main risk | Progress may feel slow | Higher-rate debt may remain longer |
| Tie-breaker | Choose the smaller balance when rates match | Choose the higher rate when balances match |

Yes. A hybrid can clear one small balance for momentum, then switch to the highest-rate debt. Model both scenarios so the motivational benefit is visible alongside the estimated interest tradeoff.
There is no universal answer. Consider payment requirements, interest rates, employer matches, emergency liquidity, and the cost of needing to borrow again after an unexpected expense.
Update the plan. Variable rates and promotional periods can change the most efficient target, so review balances and rates regularly.
