What debts should I pay off first?

Focus on high-interest debt first, typically credit cards, since interest compounds quickly and costs you the most money over time. Pay minimums on everything else and throw any extra money at the highest-rate balance until it's gone, then move to the next one. This is called the avalanche method and saves the most money mathematically. If you need psychological motivation to stay on track, the snowball method works well too — pay off the smallest balance first regardless of interest rate, which gives you quick wins and momentum. Either way, prioritize consumer debt over low-interest debt like mortgages or federal student loans, which are generally less urgent and may have tax advantages or forgiveness options.
