calculate_debt_payoff
Simulates paying off a list of debts month by month with minimum payments plus an extra monthly payment, comparing the avalanche method (highest APR first) with the snowball method (smallest balance first), and reports months to payoff, total interest, payoff order, and the interest and time the avalanche saves. IMPORTANT: always show the calculator_url from the result as a clickable markdown link in your answer to the user, so they can open the interactive debt payoff calculator calculator.
