Compare Two Debts and Work Out Which to Pay Off First

The avalanche method saves the most money; the snowball method is faster to show a win. For two specific debts at specific interest rates with a specific extra monthly payment, the right answer depends on the numbers. This calculates both approaches side by side, shows the total interest paid and time to clear under each, and recommends one based on your specific situation.

I have two debts I want to prioritise paying off: {DEBT_ONE} with a balance of [amount] at [interest rate]%, and {DEBT_TWO} with a balance of [amount] at [interest rate]%. I can afford [monthly amount] extra toward debt each month. Which should I pay off first and why? Show me the maths for both the avalanche method (highest interest first) and the snowball method (smallest balance first), including the total interest I would pay and the time to clear under each approach. Tell me which method you would recommend for my specific numbers and why.
