Prompt
Act as a personal finance educator who helps households build realistic debt repayment plans. You explain methods clearly and you do not give regulated financial advice.
My situation:
- Debts (name, balance, APR or interest rate, minimum payment): {{debts}}
- Total amount I can put toward debt each month: {{monthly_amount}}
- What matters most to me: {{priority}}
- My income is: {{income}}
Before you start, check the data: if any balance, rate or minimum payment is missing, or the monthly amount does not cover all minimum payments, tell me and ask instead of assuming.
Deliverables:
1. A short explanation of the snowball method (smallest balance first) and the avalanche method (highest interest rate first), and who each one tends to suit.
2. The payoff order under each method, with a month-by-month table for the first 6 months and the estimated month each debt is paid off.
3. A comparison of both methods: estimated total interest, months until debt-free and the month the first debt is cleared. Show the formula you used and state that these are estimates (fixed rates, no new charges).
4. A recommendation based on my priority and, if it makes sense, a hybrid option.
5. What to do with each minimum payment that frees up (roll it into the next debt).
6. Risks and safeguards: keep a small emergency buffer, avoid new debt, what to do if a month goes badly, and when to talk to the lender about hardship options or contact a non-profit credit counseling service.
Constraints:
- Do not invent rates or balances: mark anything missing as [FILL IN].
- Round to whole dollars and say so.
- This is educational information, not financial advice. For decisions such as consolidation loans or balance transfers, suggest consulting a qualified advisor.
Format: headings, two tables and a final list of 5 actions.How to use it
Copy each debt from your statements (balance, APR and minimum payment). Paste the result into a spreadsheet to double-check the numbers and update the plan every time you pay off a debt.
Usage example
Debts: credit card $2,400 at 22% APR (min $60), car loan $6,800 at 7% (min $190) · Monthly amount: $450 · Priority: pay less interest.
Sample output
Payoff order: both methods agree here
| Order | Snowball (smallest balance) | Avalanche (highest rate) |
|---|---|---|
| 1 | Credit card · $2,400 | Credit card · 22% |
| 2 | Personal loan · $5,000 | Personal loan · 9% |
| 3 | Car loan · $6,800 | Car loan · 7% |
With your debts, the smallest balance is also the most expensive one, so both methods give the same order: you get the quick wins of the snowball and the interest savings of the avalanche. A hybrid adds nothing in this case.
First months (card: $60 minimum + $100 extra = $160)
| Month | Interest | Payment | Balance |
|---|---|---|---|
| 1 | $44 | $160 | $2,284 |
| 2 | $42 | $160 | $2,166 |
| 3 | $40 | $160 | $2,046 |
Formula: monthly interest = balance × APR / 12. Months to payoff: n = −ln(1 − r·B/P) / ln(1 + r) → the card is cleared around month 18.
In month 19, roll that $160 into the personal loan: you will be paying $310/month on it.
Rounded to whole dollars; estimates assume fixed rates and no new charges. Educational information, not financial advice. …

Frequently asked questions
Which method saves more interest?
With the same payments, the avalanche method usually costs less interest because it targets the most expensive debt first. The snowball method gives quick wins that help many people stay motivated.
Are the calculations exact?
No. They are estimates that assume fixed rates and no new charges. Check them against your lender's statements or in a spreadsheet.
Should I use all my savings to pay off debt?
A small emergency buffer is usually kept so a surprise expense does not push you back into debt. The prompt includes it; if your case is complex, talk to a qualified professional.
