AI Prompt to Build a Debt Payoff Plan and Amortization Strategy

What you need

You need an itemized inventory of every outstanding liability you carry, including the outstanding principal balance and annual percentage interest rate for each account. Check your most recent billing statements or credit portal to ensure interest rates include all mandatory servicing margins and administrative fees.

Underneath the snapshot block, specify this extra input clearly: - Amount I can put toward debt each month, beyond minimum payments: state the extra cash you can dedicate to principal acceleration each month after meeting baseline minimum payments across all loans.

If you have loans with promotional zero-percent periods or upcoming rate resets, note the future interest rate so the calculation does not underestimate your carrying costs. Distinguish fixed-rate loans from variable-rate lines of credit so the model can evaluate rate sensitivity if sovereign interest rates increase.

The snapshot template below arranges your debts and assets. Copy the template, enter your balances and interest rates, add your monthly surplus figure, and paste everything with the prompt below.

Here is my financial snapshot. Use only these numbers.

Currency: [e.g. EUR]
Date: [today's date]
Age: [optional]

ASSETS
[name] — [category: cash / stocks / ETFs / crypto / property / metals / other] — [value]
[name] — [category] — [value]
...

LIABILITIES
[name] — [type: mortgage / car loan / credit card / student loan / other] — [outstanding balance] — [interest rate if known]
...

CONTEXT (optional but improves the answer)
Monthly income after tax: [amount]
Monthly spending: [amount]
Amount I add to savings or investments each month: [amount]
Value of the same assets 12 months ago: [amount]

The prompt

Copy this exact text and paste it into ChatGPT, Claude or Gemini directly beneath your snapshot block.

You are a financial analyst. Using the liabilities in my snapshot above, plus the
amount below:

Amount I can put toward debt each month, beyond minimum payments: [amount]

1. List my debts sorted by interest rate, with balance and rate side by side.
2. Build a payoff order by highest interest first. Show months to clear and total
   interest paid.
3. Build a second order by smallest balance first. Show the same figures.
4. Compare the two: the money difference, and why someone might still pick the
   slower one.
5. Flag any debt where early repayment might be a poor use of the money, and explain
   the reasoning.

Show the calculations. Ask me for rates you do not have. Do not recommend
consolidation products or lenders.

What good output looks like

The output should begin with a clean table showing your debts sorted from highest interest rate to lowest interest rate. Each row must display the debt name, outstanding principal, annual percentage rate, and current minimum monthly payment.

Next, the model builds your avalanche repayment schedule, directing all surplus monthly cash toward the highest-rate debt while maintaining minimums on the others. It states the exact number of months required to become debt-free under this method, alongside the total cumulative interest paid across all loans over the entire payoff duration.

The model then constructs the alternative snowball schedule, targeting the smallest balance first to eliminate individual accounts rapidly. It presents the identical metrics: total months to completion and total cumulative interest cost.

A direct comparison section must calculate the exact currency difference in interest between the two paths. It explains why a borrower might choose the mathematically slower snowball method, citing psychological momentum from eliminating individual monthly payments and simplifying cash flow administration.

Finally, the model flags low-interest debts, such as a fixed-rate mortgage below three percent, where aggressive early repayment yields a lower return than safe cash deposit yields or conservative index fund investments. It explains how liquidity preservation protects households during income downturns.

What this can't tell you

This prompt cannot check whether your loan agreements contain prepayment penalties or administrative fees for early principal repayment. Always check your loan terms before making accelerated repayments on fixed-term bank financing.

Language models often make compounding errors when calculating monthly amortization schedules across multiple loans, so treat the months and interest totals as estimates that should be verified with an amortization calculator. The model does not know whether your mortgage interest qualifies for tax deductions in your country, which lowers the effective interest rate of that borrowing. It has no insight into your credit score or whether refinancing would lower your rates. It cannot forecast changes in central bank lending rates that alter adjustable-rate payments.

Doing this without the retyping

Managing a debt elimination plan with external chatbots requires copying loan balances, interest rates, and minimum payments by hand every billing cycle.
