How to Pay Off Debt
The two proven strategies for eliminating debt, how to choose between them, and a worked example showing exactly how much interest each method saves.
The core problem with minimum payments
Minimum payments are designed to keep you in debt as long as possible. On a $5,000 credit card balance at 20% APR, paying only the minimum (typically 2% of the balance) will take over 30 years to pay off and cost more than $9,000 in interest — nearly double the original balance.
The solution is to pick a debt payoff strategy and make consistent extra payments above the minimum. Even an extra $50–$100 per month can cut years off your payoff timeline.
Debt avalanche vs. debt snowball
Both strategies work the same way: pay minimums on all debts, then put every extra dollar toward one target debt. The difference is which debt you target first.
Target the debt with the highest APR first, regardless of balance. Once it's gone, roll that payment into the next-highest-rate debt.
Best for: minimizing total interest paid. Mathematically optimal — you will pay less overall and get out of debt faster than any other approach.
Target the debt with the smallest balance first, regardless of interest rate. Get quick wins by eliminating accounts, then roll the freed-up payments toward the next smallest.
Best for: motivation and behavior change. Research shows people are more likely to stick with a plan that gives them early wins, even if it costs a bit more in interest.
Both are far better than paying minimums. Choose whichever you'll actually stick to — the best strategy is the one you follow.
Worked example
Three debts, $300/month available for payoff (minimums + $100 extra):
Debt A — Credit card $2,000 @ 22% APR ($50/mo min)
Debt B — Personal loan $5,000 @ 12% APR ($120/mo min)
Debt C — Car loan $8,000 @ 6% APR ($130/mo min)
────────────
Total min $300/mo
Extra $100/mo
────────────────────
Available $400/moPut the extra $100 toward Debt A (22% APR). Pay it off in ~17 months. Roll $150 total toward Debt B. Pay it off in ~26 more months. Then clear Debt C. Total interest: ~$2,100.
Same order here by coincidence (Debt A has both the highest rate and lowest balance). In scenarios where these differ, the snowball pays slightly more in total interest but eliminates accounts faster. Total interest: ~$2,300–$2,600 depending on scenario.
Step-by-step: starting your payoff plan
- 1
List every debt
Write down each debt with its current balance, interest rate, and minimum payment. Include credit cards, personal loans, car loans, student loans, and any medical debt. Knowing the full picture is step one.
- 2
Find your extra payment amount
Calculate your monthly take-home income minus all expenses. Even $50 extra per month makes a significant difference. If there's no room, look for one expense to cut temporarily — the payoff period will shrink fast.
- 3
Choose your strategy
Pick avalanche for maximum interest savings. Pick snowball if you need early wins to stay motivated. Either way, commit to it — switching strategies mid-plan erases the benefit of both.
- 4
Automate minimum payments
Set up autopay for every debt's minimum payment. Missing a payment resets progress and triggers penalty APR on credit cards. The extra payment is the only thing that should require active attention.
- 5
Roll payments forward
When a debt is paid off, don't reduce your monthly payment amount. Redirect the freed-up cash to the next target. This acceleration is what makes both strategies work.
Frequently asked questions
- Should I pay off debt or invest?
- It depends on interest rates. High-interest debt (credit cards at 18–25% APR) should almost always be paid off before investing — no investment reliably returns 20%+ annually. Low-interest debt (car loans at 4–6%, student loans at 5–7%) is more nuanced: if your employer matches 401(k) contributions, capture that match first (it's an instant 50–100% return), then apply extra money to debt.
- Does paying off debt hurt my credit score?
- Closing a credit card account can temporarily lower your score by reducing available credit and average account age. But the score impact of carrying high balances (credit utilization above 30%) is usually far larger. Paying down balances improves your score; closing the account afterward is optional.
- What about balance transfers or debt consolidation?
- A 0% APR balance transfer can save significant interest if you can pay off the balance before the promotional period ends (usually 12–18 months). Debt consolidation loans work similarly — a lower-rate loan replaces multiple higher-rate debts. Both strategies work best combined with a payoff plan; without one, they often lead to running up the original accounts again.
- How much does the order actually matter?
- For most realistic debt situations, the avalanche method saves $200–$1,500 in total interest compared to the snowball. The gap is larger when interest rate differences are big. If staying motivated is a real concern for you, the snowball's slightly higher cost is worth it — a plan you follow beats an optimal plan you abandon.
