Bars show total balance left. Avalanche shrinks the costliest debt first, so less interest is added each month; snowball clears whole accounts sooner.

How the two methods work

Both methods pay every minimum, put all spare money on one target debt, and roll a paid-off debt's payment into the next target. That roll-over is what makes them powerful. The only difference is the order: avalanche targets the highest rate, snowball the smallest balance.

Maths favours avalanche, because interest is charged as rate × balance and the highest rate costs most per dollar. Psychology often favours snowball: seeing an account hit zero in the first few months keeps people on the plan. Pick the one you'll actually stick to; the difference above tells you what that choice costs.

If your rates are high across the board, a consolidation loan or balance transfer can lower the rate first, then you pay it down the same way.

Questions people ask

What is the debt avalanche method?
Pay the minimum on every debt, then put every extra dollar on the debt with the highest interest rate. When it is gone, roll its payment onto the next-highest rate. It always costs the least interest.
What is the debt snowball method?
Pay minimums on everything and put extra money on the smallest balance first, regardless of rate. Each paid-off debt frees its payment for the next. It usually costs a little more interest, but early wins keep many people going. A study published in the Journal of Consumer Research found people who focused on closing out individual accounts were more likely to eliminate their debt.
Which is better, snowball or avalanche?
Avalanche saves the most money; snowball gives faster first wins. When your smallest debts also have the highest rates, they are the same plan. The calculator shows the exact difference for your debts, which is often smaller than people expect.
What monthly budget should I use?
Everything you can reliably put toward debt each month, including the minimums. Even $100 above the minimums can cut years off the payoff date because each freed-up payment rolls forward.
