Short answer: pay the minimum on every debt, then send every extra dollar to one target. Target the highest interest rate (avalanche) to pay the least interest, or the smallest balance (snowball) to clear accounts sooner. If anything is past due, or secured by something you could lose like a car, catch that up first.
Debt advice online turns into a personality quiz. Avalanche people. Snowball people. You just want the balances gone. Below is a simple decision rule and a way to see how that choice plays out over time. Want your own numbers first? Try the free debt payoff calculator.
Avalanche means highest interest rate first. Math likes this one. Snowball means smallest balance first. Motivation likes this one. Both work if you stick with them. Neither works if you keep switching every month because a podcast said something new.
Pick one. Write it down. Run it until something meaningful is paid off. Then reassess.
Say you have an $8,000 card at 22%, a $2,400 store card at 19%, and a $14,000 student loan at 5%. Avalanche points you at the 22% card first, even though the store card looks smaller and more “winnable.” Snowball points you at the $2,400 balance so you get a clean win sooner. Either path can finish the stack. Switching midstream usually means you never finish either one.
If interest is bleeding you and you can stay motivated without quick wins, avalanche is the cleaner money choice. If you have abandoned plans before, snowball's early payoff can keep you in the game. Honesty about your own follow-through beats a pure spreadsheet flex.
Write the rule somewhere you will see it: “Minimums everywhere. Extra to the 22% card.” Or “Extra to the smallest balance until it is gone.” When a bonus or tax refund shows up, send it to the same target instead of inventing a third method on the spot. The method only works if the extras keep landing in one place.
Ignore the voice that says you are failing if you still have debt. Ignore the idea that every extra dollar must do only one thing forever. Life still needs a buffer. An empty checking account while you crush a card can create new debt. That is not progress. That is a loop.
Also ignore the urge to compare your payoff speed to strangers on the internet. Someone with no rent and a $1,200 card is not living your month. Your plan only has to survive rent on the 1st, groceries mid-month, and the minimums that keep accounts current.
A workable order often looks like this. Minimums everywhere. A small cash cushion so a flat tire does not become another 22% balance. Then every leftover dollar on one target. When that target hits zero, roll the payment to the next one. The roll-up is where the plan gets teeth.
A few debts can jump the line. A 0% promo rate that ends soon, since whatever balance is left starts charging the regular rate once it expires, and some store cards add back the deferred interest too. Anything in collections or owed in taxes, which carries bigger consequences than a card. Get a collections balance confirmed in writing before you pay it.
How much extra? Start with a number you can repeat after rent and groceries, even on a tight month. An extra $150 every payday beats a heroic $800 that lasts three weeks. Consistency is what turns 22% into a closed account instead of a recurring argument.
Calm order of operations
Catch up, then cover minimums
Past-due first. Then every account gets its minimum so nothing goes delinquent.
Keep a small cash buffer
So a flat tire does not become a new card balance at 22%.
Send every extra dollar to one target
Usually the highest APR. When it is gone, roll the payment to the next.
In Flan you can enter debts with balances and rates, then watch payoff paths on a projection. Switch the payoff method and see how the timeline changes. You are comparing paths, not mottos. You are comparing futures.
The best debt plan is the one you finish. Choose avalanche or snowball on purpose, protect a little cash, and put the extras on one balance at a time.
When you can see the payoff date on a timeline, the argument gets quieter. That is usually when the work starts sticking. Carrying student loans too? See Student loans on the timeline.
