Why debt payoff order matters

Three hypothetical debts, fixed minimum payments and $300 a month extra. See what happens when you pay minimums only, smallest balance first, or highest rate first.

Scene 1

Three debts

Store card: 15% APRCredit card: 24% APRCar loan: 7% APR
A store card with $1,500 at 15% APR ($50 minimum), a credit card with $8,000 at 24% APR ($200 minimum) and a car loan with $12,000 at 7% APR ($300 minimum). Taller stacks are larger balances; darker colors are higher rates.

Scene 2

Minimums only

Month 0 of 82

Interest paid: $0

Paying only the minimums, the stacks shrink slowly. It takes about 82 months to be debt-free, with about $10,350 in interest along the way.

Scene 3

Snowball: smallest balance first

Month 0 of 30

Interest paid: $0

Quick wins keep you motivated.

The extra $300 goes to the smallest balance, the store card, which is paid off in month 5. Its payment then rolls into the next smallest debt. Debt-free in 30 months, with about $3,600 in interest. Quick wins keep you motivated.

Scene 4

Avalanche: highest rate first

Month 0 of 30

Interest paid: $0

Less interest overall.

The extra $300 goes to the 24% credit card first, then rolls to the next highest rate. Debt-free in 30 months, with about $3,400 in interest, about $195 less than the snowball. Less interest overall.

Side by side

Months to debt-free

Minimums only82 months

Avalanche (highest rate first)30 months

Total interest

Minimums only$10,352
Snowball (smallest balance first)$3,601
Avalanche (highest rate first)$3,406

Both strategies beat minimums by a wide margin. The better method is the one you'll stick with.

Minimums only: about 82 months and $10,350 in interest. Snowball: 30 months and about $3,600. Avalanche: 30 months and about $3,400. Both strategies beat minimums by a wide margin, and the better method is the one you'll stick with.
