Steps

Find payoff amount, APR, months left on your loan statement.
Prequalify with 2-3 credit unions using soft pulls; rate-shopping within ~14-45 days counts as one inquiry for scoring.
Ask AI to compare total cost including any fees and term change.
Don't extend the term so far that you pay more overall.
