Which Debt to Pay First — Snowball vs Avalanche
- •Avalanche = highest rate first (saves the most interest)
- •Snowball = smallest balance first (momentum keeps you going)
- •Pay every minimum, then aim all spare cash at one
The short answer
On the numbers, paying the highest-rate debt first wins — the same money kills the most interest. In practice, though, the people who actually finish are often those who clear small balances first and build momentum. Either way one rule holds: pay every minimum, then aim all the spare cash at a single target.
How the two differ
| Avalanche | Snowball | |
|---|---|---|
| Order by | Highest rate | Smallest balance |
| Strength | Least total interest | A debt disappears fast |
| Weakness | Slow to feel, easy to quit | Costs more interest |
When rates differ sharply, the avalanche's edge is clear. Mix a 20%-plus cash advance with a 3% student loan and the order alone changes the total by a meaningful sum. When rates are all similar, the difference shrinks — so pick whichever you will actually stick with.
Doing it in practice
- List every debt on one page — balance, rate, minimum payment
- Keep paying every minimum (never let one fall into arrears)
- Work out the spare cash and add it to one target only
- When that debt clears, move the whole payment to the next
- Do not create new debt — lower the freed-up card limit
Common misconceptions
The plan to clear all debt before saving anything usually collapses. With no emergency fund, an unexpected cost sends you straight back into borrowing and undoes the progress. Building even a small buffer first, then focusing on repayment, holds up better.
Frequently Asked Questions
What if I only pay the minimums?
You avoid arrears, but the principal barely moves. On card debt especially, most of the minimum goes to interest, so the balance can look unchanged after years of paying.
Invest or repay debt first?
Compare the rates. If the debt costs more than you expect to earn, repay first. Killing 15% interest is the same as earning 15% with certainty.
Is consolidating better?
It helps if the rate genuinely falls. But a longer term can raise total interest, so check both the term and the total — and the real test is not using the freed-up card limit again.
Where does money borrowed from family go?
With no interest, it sits last by the numbers. But if it is straining the relationship, moving it up is a reasonable choice. The math is not the only consideration.
Should I close a paid-off card?
Not necessarily. Closing an old card shortens your credit history, which can hurt your score. Lowering the limit and putting it away is usually the safer move.
