Frequently Asked Questions
What is the avalanche vs. snowball method?
The avalanche method pays off the highest-interest debt first, saving the most money. The snowball method pays off the smallest balance first, building momentum. Mathematically, avalanche wins — but snowball can be more motivating.
How much does an extra $100/month matter?
On a $10,000 credit card at 20% APR with a $250 minimum payment, adding $100/month cuts payoff time from ~62 months to ~38 months and saves over $2,400 in interest.
Should I pay off debt or invest?
If your debt interest rate is higher than your expected investment return (typically 7%), pay off debt first. Always capture your full 401(k) employer match first — that's a guaranteed 50–100% return.
What is a minimum payment trap?
Credit card minimum payments are designed to keep you in debt as long as possible. On a $5,000 balance at 20% APR, paying only the minimum (~$100) could take over 30 years and cost more than $9,000 in interest.
