Method

Snowball vs Avalanche

Two proven ways to attack debt. One saves the most money, one keeps the most people going. Here is how to choose — and how to combine them.

Same Money, Very Different Feeling

Both methods start identically: pay the minimum on every debt, then throw every spare dollar at ONE target debt. They only differ on which debt you target first.

The Snowball Method

Target the smallest balance first, regardless of interest rate. When it clears, roll its whole payment into the next-smallest. Accounts disappear quickly, which produces visible wins early — and behavioural studies consistently find that more people finish with snowball than with any other method.

Choose snowball if you have tried before and stalled, if you have several small debts, or if you need to feel progress to stay in the fight.

The Avalanche Method

Target the highest interest rate first, regardless of balance. It is mathematically optimal — it always costs the least total interest and always finishes at least as fast. The catch is that the first target may be a large balance, so the first win can be months away.

Choose avalanche if you are numbers-driven, your rates vary widely (say 6% versus 24%), or the balances are similar in size.

A Worked Example

  • Card A: $900 at 19%
  • Card B: $4,500 at 24%
  • Car loan: $8,000 at 7%

With $600 a month above minimums, avalanche kills Card B first and saves a few hundred dollars in interest overall. Snowball kills Card A in about six weeks, which for many people is the difference between continuing and quitting. A finished snowball beats an abandoned avalanche every time.

The Hybrid Most People Should Use

Clear any debt under about $1,000 first for the quick win, then switch to strict highest-interest-first for everything else. You get the psychological kickstart and keep almost all of the mathematical advantage.

Rules That Apply To Both

  • Never miss a minimum payment — fees and rate hikes undo your progress instantly.
  • Roll every cleared payment forward. That rolling snowball is where the speed comes from.
  • Cut the interest rate first where you can — see consolidation.
  • Track the total owing monthly, not the individual balances.
  • Add every windfall — tax refund, bonus, gift — straight onto the target debt.

Once the method is chosen, the fuel matters more than the formula. Free up cash on cut your debts and add income on grow income.
