Frequently asked questions

Common questions about debt payoff strategies.

The avalanche method prioritizes paying off debts with the highest interest rate first while making minimum payments on all others. Once the highest-rate debt is eliminated, you redirect that payment to the next highest-rate debt, creating a cascading payoff effect. This method minimizes total interest paid over time and is the mathematically optimal strategy for reducing the overall cost of your debt. The trade-off is psychological: if your highest-rate debt also has a large balance, it may take a long time before you see your first debt fully paid off, which some people find discouraging.
The snowball method prioritizes paying off the smallest balance first, regardless of the interest rate, while making minimums on all others. Once the smallest debt is paid off, you roll that payment toward the next smallest balance, building momentum. While it typically costs more in total interest than the avalanche method, research from the Harvard Business Review and consumer behavior studies consistently shows that the quick wins of eliminating individual debts improve motivation and completion rates -- making snowball users more likely to actually finish their debt payoff.
Consolidation makes sense when three conditions are met: you can qualify for a meaningfully lower interest rate than your current debts average, you have multiple payments that are difficult to track, and you are disciplined enough not to run up new balances on the accounts you pay off. It is generally most effective for high-rate credit card debt. Calculate your weighted average current rate first -- if your consolidation loan rate is higher, consolidation will cost more total interest regardless of the lower monthly payment. Use this calculator to compare both strategies side by side with your actual numbers.
Applying for a consolidation loan causes a hard inquiry that typically drops your score by a few points temporarily. Long term, consolidation can improve your credit profile in two ways: paying off revolving credit card balances reduces your credit utilization ratio -- one of the most heavily weighted factors in your score -- and having a single installment loan to manage reduces the risk of missed payments. Most borrowers who maintain on-time payments on their consolidation loan see their scores recover and improve within 6 to 12 months of consolidating.
Credit cards, personal loans, medical bills, and other unsecured debts are the most common and appropriate consolidation candidates. Federal student loans can be consolidated through the federal Direct Consolidation program (preserving federal protections) or refinanced privately (losing those protections). Secured debts like mortgages and auto loans are not typically included in personal consolidation loans. Mixing debt types can have unintended consequences -- for example, consolidating federal student debt into a private loan permanently removes access to income-driven repayment and forgiveness programs. Always confirm the loan type before including it in a consolidation plan.

About this calculator

The avalanche payoff simulation applies your total monthly budget (minimums plus extra payment) to debts in descending interest rate order each month, recalculating balances with daily-equivalent monthly interest accrual. The consolidation scenario uses the standard amortization formula on the combined balance. Results are estimates and assume consistent payments with no new debt added.

Debt payoff methodology follows guidance published by the Consumer Financial Protection Bureau (CFPB). Consolidation loan rate benchmarks reference Federal Reserve G.19 Consumer Credit data for personal loan rates.
