Can AI make me a debt payoff plan?

Half. AI explains the snowball and avalanche methods and lays out an order to pay your debts. Month-by-month interest math is where it slips, so check the numbers in a calculator.

01Why half-bot

  • Choosing an order to pay debts is simple logic AI handles well.
  • Interest compounding over many months is easy for a chat app to get wrong.
  • A spreadsheet or payoff calculator checks the math for free.

Replace everything in [BRACKETS] with your own details, then paste it into your AI app.

prompt.txt
Help me plan how to pay off my debts. You are a coach, not a financial advisor.

My debts (name, balance, interest rate, minimum payment): [LIST]
Total I can pay each month: [AMOUNT]

Give me:
1. The payoff order using the avalanche method (highest rate first) and the snowball method (smallest balance first), side by side.
2. How much extra goes to the first debt each month after all minimums are paid.
3. Which method saves more interest, and which gives faster early wins.
Rules: do NOT give exact payoff dates or total interest unless you show the full month-by-month math. Tell me to confirm numbers in a payoff calculator.

03Steps

  1. List every debt with its rate and minimum.
  2. Pick a method.
  3. Check the timeline in a free payoff calculator or spreadsheet before you commit.

04What can go wrong

  • Wrong interest math can make a plan look faster than it is.
  • If debt feels unmanageable, a nonprofit credit counselor can help.

05What to use

An AI chat app for the plan, plus a spreadsheet or payoff calculator for the math.

06Our test run

ClaudeSep 28, 2026Passed with a catch

Sample input we used: Card A $2,400 at 24%, Card B $900 at 18%, car loan $6,000 at 6%; $500 a month.

  • Both payoff orders correct
  • Extra-payment math correct ($235)
  • Still gave a rough timeline (“about 4 months”) the prompt said to verify

What came back (excerpt):

Minimums: $60 + $25 + $180 = $265. Extra each month: $500 − $265 = $235.

Confirm any timeline in a payoff calculator.

One run with an invented sample, checked against the prompt's own rules. Your results can differ; how we test.
