Debt Payoff Strategy Planner
Anyone carrying multiple debts — credit cards, student loans, car loans — uses this prompt to cut through confusion and get a concrete, mathematically optimized payoff plan with a month-by-month schedule they can follow immediately.
Prompts
You are a personal finance advisor specializing in debt elimination. I will provide a list of debts. For each debt, I will give you: the lender or debt name, current outstanding balance, annual interest rate, and current minimum monthly payment. I will also tell you the total extra amount I can put toward debt each month beyond all minimums. My debts: [DEBT LIST — name, balance, interest rate, minimum payment] Extra monthly payment available: [EXTRA MONTHLY PAYMENT] **Your task:** 1. **Avalanche Method Analysis** Rank debts by interest rate, highest first. Apply the extra payment to the highest-rate debt while paying minimums on all others. Calculate total interest paid and the month/year of full payoff. 2. **Snowball Method Analysis** Rank debts by balance, smallest first. Apply the extra payment to the smallest balance while paying minimums on all others. Calculate total interest paid and month/year of full payoff. 3. **Comparison Table** Present a side-by-side table showing: total interest paid, total months to payoff, and number of debts eliminated in the first 12 months for each method. 4. **Recommended Approach** State which method you recommend and why, based on the specific debt profile. If the interest savings between methods exceed $500, default to avalanche. If the difference is under $500 and there are three or more debts, consider snowball for motivational value. 5. **Month-by-Month Schedule (Recommended Method)** Produce a payoff schedule for the recommended method showing: month, payment applied to each debt, remaining balance, and cumulative interest paid to date. Continue until all debts reach zero. Use a clear table format. Flag each debt-free milestone in the schedule.
Prompt Variables
Replace each placeholder with your specific information:
[DEBT LIST — name, balance, interest rate, minimum payment][EXTRA MONTHLY PAYMENT]What You'll Get
Two complete payoff analyses (avalanche and snowball), a comparison table showing total interest and timeline for each method, a clear recommendation with rationale, and a full month-by-month payoff schedule for the recommended approach.
💡 Pro Tip
After running the initial plan, re-run it every six months updating balances and interest rates. Refinancing one debt mid-plan can dramatically shorten your timeline — the AI will recalculate the entire schedule.

Claude
Best choice for complex debt scenarios with five or more debts — Claude maintains accurate running balances throughout long payoff schedules without calculation drift. Paste your debt list as a simple table.
ChatGPT
Reliable for up to five debts. Use the Code Interpreter (Data Analysis) mode so GPT runs actual calculations rather than estimating — this prevents rounding errors in long amortization schedules.
Perplexity
Less suited for calculation-heavy tasks. Better used to research refinancing or balance-transfer options after identifying your payoff strategy.
