Paying Off Debt Faster: Avalanche vs Snowball
With several balances and a fixed amount of spare cash each month, the only real decision is which balance gets the extra money. Two orderings dominate the discussion.
Avalanche: highest rate first
Pay minimums everywhere and send every spare dollar to the highest interest rate. This is mathematically optimal — it always produces the lowest total interest and the earliest debt-free date.
Snowball: smallest balance first
Target the smallest balance instead, so accounts close sooner. It costs slightly more interest, but the visible wins keep many people on the plan. A plan you finish beats an optimal plan you abandon.
Quantify the difference before choosing
Use the credit card payoff calculator on each balance to see the interest cost of each order. When the gap is small, choose the order you will stick to. When the gap is large, avalanche is worth the patience.
If a balance transfer or consolidation offer is on the table, compare the fee against the interest saved over the promotional window rather than the headline rate alone.
