Here's the uncomfortable math: a $6,000 credit card balance at a 24% APR — territory a lot of cards sit in these days — costs you about $120 in interest in the first month alone. Pay only $150 a month and you'll be paying for 81 months and hand the card company roughly $6,191 in interest. More than the debt itself.
Bump that payment to $400 and the same debt is gone in 18 months with about $1,205 in interest. Same balance, same APR — the only variable that matters is how hard you hit it. Here's the fastest route.
Step 1: Get every debt on one page
You can't attack what you can't see. List every card and loan with four numbers: balance, APR, minimum payment, and due date. Most people have never seen their total debt as one number — it stings for about five minutes, and then it becomes a target.
Step 2: Pay minimums on everything, then attack one card
Splitting your extra money evenly across three cards feels fair but wastes interest. The faster method: pay the minimum on everything, then throw every spare dollar at one card until it's dead.
Which one? Mathematically, the highest APR first (the avalanche method) always wins. If you need early wins to stay motivated, the smallest balance first (snowball) costs a bit more but is easier to stick with. We ran the actual numbers on both in debt snowball vs avalanche — for most credit card situations, the difference is smaller than people expect, so pick the one you'll actually follow.
Step 3: Fix your payment — never pay the "minimum due"
The minimum payment shrinks as your balance drops, which quietly stretches your payoff by years. Instead, pick a fixed number — say $400 — and pay it every month no matter what the statement asks for. When one card is paid off, roll its entire payment into the next card. That's how an 81-month slog becomes an 18-month project.
Step 4: Find the extra $100–$250
The gap between $150 and $400 a month usually isn't hiding in one big expense — it's spread across subscriptions, food delivery, and untracked spending. A basic budget finds it fast. If you don't have one, our free One-Page Budget Starter takes about five minutes: enter income and planned spending, and it shows exactly what's left over to send at your debt.
Step 5: Watch your debt-free date get closer
The single most motivating number in debt payoff is the month you'll be done. Our Debt Payoff Planner ($8.99, Excel & Google Sheets) runs both snowball and avalanche on your actual debts, shows the payoff month for every card, and recalculates instantly when you add an extra payment. Code LAUNCH20 takes 20% off through August 15.
The short version
List every debt. Pay minimums on all but one. Fix your payment amount and never let it shrink. Roll finished payments into the next card. On a $6,000 balance at 24% APR, going from $150 to $400 a month saves you about $4,986 in interest and 63 months of payments. That's the whole trick — there's no secret beyond concentration and consistency.
