Frequently Asked Questions

Q: What is the fastest way to pay off debt?

The avalanche method is mathematically fastest. Combine it with increased income (side hustle), reduced expenses (budget), and consolidating into lower-rate options like a balance transfer card or personal loan.

Q: Should I pay off debt or invest?

If debt interest is above your expected investment return, pay debt first. Credit cards at 20%+ always take priority. For lower-rate debt (5–7%), investing simultaneously makes sense — especially if your employer offers a 401(k) match, which is an instant 50–100% return.

Q: Is debt consolidation a good idea?

It can be — if you genuinely get a lower rate and stop accumulating new debt. Risks include extending your repayment period, fees, and using freed-up credit cards again. Always calculate total cost before consolidating and read the fine print.

Q: How does a debt payoff calculator help?

It removes guesswork by showing your exact debt-free date at any payment level, total interest under different strategies, and how much extra monthly payment gets you to a specific payoff date. A concrete debt-free date is one of the most powerful motivators for sticking to a plan.

Q: What debt should I pay off first?

Priority order: (1) past-due bills to avoid collections, (2) secured debts where default loses an asset, (3) highest-interest unsecured debt (usually credit cards at 18–26%), (4) remaining debts by rate or balance. Always maintain minimums on everything while attacking your priority debt.
