Which Debt Should You Pay Off First? A Simple Decision Guide

The Order You Pay Matters More Than You Think

You've got a credit card, a car loan, maybe a personal loan or some student debt — and one question: when there's extra money this month, where should it go? It feels like a small decision. It isn't. On the same debts, with the same budget, the payoff order alone can swing what you pay in interest by hundreds or thousands of dollars.

The good news: the decision is simpler than the internet makes it look. There are two default rules, a handful of exceptions that override them, and that's it.

The Two Default Rules

Rule one: highest interest rate first — the avalanche method. Your highest-APR debt is the most expensive dollar you owe, so every extra payment there saves the most money. If you're optimizing for total cost, this is the answer.

Rule two: smallest balance first — the snowball method. You knock out entire accounts quickly, free up their minimum payments, and build the kind of momentum that keeps a plan alive. If you've started and abandoned payoff plans before, this is probably your answer. Our snowball vs. avalanche breakdown goes deeper on choosing between them.

The Exceptions That Override Everything

Before applying either rule, check for these — they jump the queue no matter what:

• Payday and title loans first. Always.

  With effective rates that can run 300%+ APR, these aren't debts, they're emergencies. Clear them before anything else.



• Anything past due gets current first.

  Late fees, penalty APRs, and credit damage compound faster than interest. Stabilize every account before optimizing any of them.



• A 0% promo that's about to expire.

  If a balance transfer or store-card promotion ends soon and the balance will survive it, that debt is about to become your most expensive. Get ahead of the cliff.



• Low-rate secured debt goes last.

  A 6% car loan or a mortgage almost never deserves extra payments while a 24% credit card exists. Pay the minimums and aim your firepower at the expensive stuff.

What the Difference Looks Like in Real Numbers

Take three debts totaling $18,000: a $6,000 credit card at 24% APR, a $3,000 personal loan at 12%, and a $9,000 car loan at 7%. Paying $100 above the minimums each month, the avalanche order (card, loan, car) gets you debt-free in 38 months with about $4,023 in interest. The snowball order (loan, card, car) takes 40 months and about $5,021.

That's roughly a $1,000 spread from ordering alone — same debts, same budget. But notice the snowball still beats minimum-only payments by ten months and $1,457. The worst choice isn't picking the "wrong" method. It's not picking one.

Your 60-Second Decision

Here's the whole guide in one pass: clear any payday loans and past-due accounts, defuse any expiring 0% promos, then choose your rule — avalanche if the interest savings motivate you, snowball if finished accounts do. Point every spare dollar at one target debt while paying minimums on the rest, and roll each freed-up payment into the next target.

Then make it concrete: run your actual debts through the free avalanche calculator or snowball calculator and compare your debt-free dates side by side. Seeing your own numbers ends the debate faster than any article can.
