Frequently Asked Questions
How long does it take to pay off $10,000 in credit card debt?▼
At 18.99% APR with a $300/month payment, it takes approximately 44 months (3.7 years) to pay off $10,000, with $3,108 in total interest. Increasing the payment to $400/month cuts it to 29 months and saves over $1,200 in interest. Minimum payments (typically $25–$35/month) could take 10+ years.
What is the fastest way to pay off debt?▼
The fastest strategies are: (1) Debt Avalanche — pay minimums on all debts, then put all extra money toward the highest interest rate debt first. This minimizes total interest paid. (2) Debt Snowball — pay smallest balances first for psychological wins that keep you motivated. Avalanche saves more money; snowball has a higher completion rate for many people.
Does paying extra every month really make a big difference?▼
Yes — dramatically. On a $10,000 credit card balance at 19% APR, adding just $100/month extra reduces payoff time from 44 months to 30 months and saves over $800 in interest. Extra payments go directly to principal, which reduces the balance on which future interest is calculated, creating a compounding benefit.
What is an amortization schedule?▼
An amortization schedule shows how each monthly payment is split between interest and principal. Early in the loan, most of your payment covers interest. Over time, as the balance decreases, less goes to interest and more reduces principal. This is why extra early payments are so powerful — they shift the entire schedule forward.
What is the minimum payment trap with credit cards?▼
Credit card minimum payments are typically 1–3% of the balance, which barely covers the interest. At 20% APR on a $5,000 balance with a 2% minimum payment ($100 starting), it takes over 10 years to pay off and costs $3,000+ in interest. This is by design — card issuers profit from extended payoff timelines.
Should I pay off debt or invest?▼
A general rule: if your debt interest rate is higher than your expected investment return (typically 7–10% for index funds), pay off the debt first. Credit card debt at 18–25% APR should almost always be prioritized over investing. Student loan or mortgage debt at 4–6% is a closer call — many financial advisors suggest doing both in parallel.
