What is the debt avalanche method?
The debt avalanche method prioritizes paying off debts with the highest interest rates first, while making minimum payments on all other debts. Once the highest-rate debt is eliminated, you roll that payment into the next highest-rate debt. This approach minimizes the total interest you pay over time and is considered the most mathematically efficient strategy. See also our Net Cash Flow — Cash Flow.
What is the debt snowball method?
The debt snowball method focuses on paying off your smallest debt balance first, regardless of interest rate. Once that debt is gone, you add its payment to the next smallest debt, creating a 'snowball' effect. While it may cost more in total interest than the avalanche method, many people find it more motivating because you see debts eliminated faster.
How long does it take to pay off debt?
The time to pay off debt depends on three key factors: your current balance, your interest rate, and your monthly payment. A $5,000 balance at 18.9% APR with a $150/month payment takes roughly 44 months and costs about $1,500 in interest. Increasing your payment — even by $50/month — can shave years off your timeline.
How do you calculate interest on a credit card?
Credit card interest is typically calculated by dividing your annual interest rate (APR) by 12 to get a monthly rate, then multiplying that by your current balance. For example, an 18% APR equals a 1.5% monthly rate. On a $5,000 balance, that's $75 in interest in the first month alone — meaning most of your minimum payment may go toward interest rather than reducing your balance.

How do you calculate a monthly debt payment?
Your required monthly payment is typically your minimum payment set by the lender, but you can choose to pay more. The formula for a fixed payoff period uses: Payment = Balance × [monthly rate / (1 − (1 + monthly rate)^−n)], where n is the number of months. This calculator handles that math for you — just enter your balance, rate, and payment amount.
How can I pay off large amounts of debt fast?
The fastest strategies include: (1) making extra payments whenever possible, (2) applying any windfalls like bonuses or tax refunds directly to your balance, (3) consolidating high-interest debt into a lower-rate loan, and (4) cutting discretionary expenses and redirecting that cash to debt. Even an extra $50–$100 per month can cut years off your payoff timeline.
Does it make sense to pay more than the minimum payment?
Yes — paying only the minimum on high-interest debt can mean you're in debt for years longer than necessary and pay thousands more in interest. For example, on a $5,000 credit card balance at 19% APR, paying only the minimum could take over 15 years to clear. Doubling your payment can cut that to under 4 years.
What's the difference between debt consolidation and debt payoff?
Debt payoff means actively paying down your existing debts according to a strategy (avalanche or snowball). Debt consolidation involves combining multiple debts into a single loan, ideally at a lower interest rate, to simplify payments and reduce costs. Consolidation can be a useful first step, but a clear payoff strategy is still essential to becoming debt-free.
