Debt Snowball vs Avalanche Comparison
Compare two payoff orders with your numbers.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Compare payoff methods for my debts. For each debt: name, balance, interest rate, minimum payment, due date: [DEBT_TABLE]. Extra amount I can pay each month: [EXTRA_PAYMENT]. Currency: [CURRENCY]. Calculate and display two schedules: smallest balance first and highest interest rate first. For each show the order of payoff, the month each debt is cleared, the total interest paid, and the total months to be debt free, using month-by-month steps that I can audit (show the first six months in a table, then the summary). Explain the difference in plain words, and name the behavioural trade-off (momentum versus cost) without picking for me. State your assumptions about compounding and fees. Add a note on checking whether any debt has penalties for early payment, to be verified with the lender, and on free debt advice services in [JURISDICTION] for anyone struggling to meet minimums. Add a worked miniature comparison with three invented debts so I can check the method by hand: balances of 500, 2,000 and 4,000, rates of 8, 15 and 22 percent, minimum payments of 25, 60 and 100, and an extra 150 per month. Show the first three months of each method in a table, state the payoff order for each, and explain in a sentence why the totals differ. Label it as an illustration. Then add a section that tests the sensitivity of the result: what changes if the extra payment is 50 higher or lower, and if the highest rate is a promotional rate that expires. Include a plain-language list of non-numeric factors (motivation, a debt with a guarantor, a debt that blocks a credit decision) that a spreadsheet cannot weigh, without telling me which to choose. Please keep the answer educational and avoid personal investment recommendations. If a rule differs by place, say so and tell me to confirm it with a professional in [JURISDICTION].

Debts: Card X 500 at 8% (min 25); Card Z 2,000 at 15% (min 50); Loan Y 4,000 at 22% (min 80). Extra 150 a month. Snowball (smallest balance first): X cleared in month 3, Z in month 14, Y in month 34. Total interest about 1,970. Avalanche (highest rate first): Y and X both cleared by month 22, Z in month 29. Total interest about 1,420; debt free five months earlier. Difference: about 550 in interest here, because the large balance carries the highest rate. The snowball gives an early win in month 3; the avalanche costs less. Check early repayment penalties with each lender. Free debt advice exists in [JURISDICTION] for anyone struggling to meet minimums.
