You can't build a payoff plan on a number you're guessing. Pull every balance, interest rate, and minimum payment into one place. Most people underestimate their total debt by 15–20% because they avoid looking at the full picture. That avoidance is the first thing to kill.
Pull out your credit card statements, loan documents, medical bills, and any buy-now-pay-later balances. For each debt, write down four numbers: the creditor name, current balance, APR (interest rate), and minimum monthly payment.
