Snowball builds momentum with quick wins. Avalanche saves the most interest. Compare shows you the honest tradeoff.
Here's what both methods do for you
Same debts, same budget, two strategies. The 'best' one is whichever you'll actually finish.

Attack this debt first
Store card
$1,150.00 balance · 28.99% APR
Pay the minimum on everything else. Send every extra dollar here until it hits zero — then roll its full payment into the next debt in line.
What this means in plain English
At $450.00/month, you'll be debt-free in 2 yr 11 mo — around May 2029. You'll pay $3,402 in interest along the way.
Your first real win shows up in month 8, when Store card hits zero. That's the moment the plan starts to feel real.
The honest answer: the difference between snowball and avalanche is small here ($0 and 0 mo). Pick whichever you'll actually stick with. If you've stalled before, snowball's quick wins usually keep you going.
Snowball vs avalanche — the honest tradeoff
Same debts, same monthly budget. Different order. Here's what changes.
Debt snowball
Pays smallest balance first
Debt-free by
May 2029
Total interest
$3,402
Emotional payoff: A real win in the first months — one closed account, then another. People who've stalled before usually finish with this method.
Money payoff: Costs a little more interest because higher-APR debts wait.
Debt avalanche
Pays highest APR first
Debt-free by
May 2029
Total interest
$3,402
Emotional payoff: Slower first win — you might be paying on the same debt for months before it closes.
Money payoff: Usually saves the most interest because it kills your most expensive debt first.
Verdict
The difference is small ($0 and 0 mo). Pick the one you'll finish.
The math matters less than consistency. Both methods only work if you keep going.

Honest math, honest limits
How we calculate
Each month, we charge interest on your remaining balance (APR ÷ 12), then apply your budget — minimums first, then extra dollars to your priority debt. When a debt closes, its minimum rolls into the next priority.
Always pay every minimum
The plan only works if every account stays current. Late fees, penalty APRs, and credit damage can wipe out months of progress.
Snowball = smallest balance first
Quick wins keep you motivated. Costs a little more interest in exchange for momentum.
Avalanche = highest APR first
Saves the most interest. Slower first win — your priority debt may take longer to close.
This is an estimate
Real life has fees, balance changes, promo APRs ending, new charges, and creditor-specific rules. Use this to plan, then check your statements monthly.
Educational, not advice
No signup, no upsell, no consolidation pitch. Just clearer math so you can make a calm decision.
Quick answers
What is the debt snowball method?
The snowball method pays off your smallest balance first while making minimum payments on everything else. Once that debt is gone, you roll its payment into the next smallest. It's designed for momentum — you get a real win fast, and that win keeps you going.
What is the debt avalanche method?
The avalanche method targets the debt with the highest interest rate first while paying minimums on everything else. When the highest-rate debt is gone, you move to the next highest rate. It usually costs the least in total interest and finishes a bit faster.
Which method saves more money?
Avalanche almost always saves more interest because it kills your most expensive debt first. On many real plans the savings are real but smaller than people expect — sometimes a few hundred dollars, sometimes a few thousand. The calculator above shows your exact difference.
Which method helps motivation more?
Snowball wins on motivation for most people. Closing a whole account in the first few months feels real, and that feeling is what keeps people going when they're tired. If you've started and stopped a payoff plan before, snowball is usually the safer bet.
Should I pay off the smallest balance first?
If you need a quick win to stay motivated, yes — that's snowball. If you'd rather save the most money and you'll stay consistent without quick wins, target the highest APR instead — that's avalanche. Both work. The best method is the one you'll actually finish.
What happens if I can only add a little extra each month?
Even an extra $25–$100 a month can cut months or years off your payoff and save hundreds in interest. The 'What changes if…' section above lets you test small amounts and see the impact instantly.
Can I use this for credit cards, personal loans, and medical debt?
Yes. Add any fixed-rate debt with a balance, an APR, and a minimum payment — credit cards, personal loans, student loans, medical bills on a payment plan, BNPL, even a 0% promo card (use 0 for APR). The math works the same.
Why is my debt-free date longer than I expected?
Two reasons: most minimum payments barely beat the interest charge, and most plans assume no new charges. If you keep using a card while paying it down, payoff stalls. Lock the card, set a fixed monthly amount, and the date moves in fast.
