How to manage your money with ChatGPT or Gemini: budgeting, saving and debt in 8 prompts

Making a budget is boring, which is why almost nobody does it. An AI assistant can turn it into a ten-minute conversation. Here are ready-to-copy prompts.

⚠️ Important: AI helps you get organized and understand things, but it isn’t a financial advisor. Don’t ask it what to invest in, and never give it your passwords or card numbers.

You don’t need to connect your bank. Just:

Export your transactions for the last month or quarter to Excel or CSV from your bank’s website.
Delete the columns with account numbers, names and personal descriptions.
Or simply type out your approximate expenses.

8 useful prompts

1. Your budget in 5 minutes

I take home $3,200 a month. My fixed costs are: rent $1,400, utilities $160, phone and internet $90, transportation $150. Build me a monthly budget using the 50/30/20 rule adapted to my situation, in a table.

The 50/30/20 rule splits income into 50% needs, 30% wants and 20% savings. The AI adapts it to your numbers.

2. Hunt down sneaky spending

Here are my transactions for last month (no personal data). Group them by category, tell me where I’m spending more than usual and flag any recurring subscriptions.

Forgotten subscriptions are the classic: streaming, apps or the gym you never go to.

3. A savings goal

I want to save $3,000 for a trip in 10 months. Given my budget, is that realistic? Give me a month-by-month plan and three ideas for cutting costs.

4. Understand a loan

I’m offered an $8,000 loan over 5 years at 7% interest with a 2% origination fee. Explain how much I’ll pay in total and the difference between the interest rate and the APR.

Always ask it to show the math. For important figures, double-check with your lender’s calculator.

5. Get out of debt

I have three debts: credit card $1,200 at 22%, car loan $4,000 at 6% and personal loan $2,500 at 9%. Explain the avalanche method and the snowball method using my numbers.

6. A cheaper grocery bill

We’re a household of 3 and spend about $650 a month on food. Give me 10 concrete ideas to get it down to $550 without eating worse.

More ideas in meal planning and grocery lists with AI.

7. Compare two offers

Compare these two phone or energy plans in a table and tell me which is cheaper for a usage of X.

8. Learn the concepts

Explain inflation, an index fund and compound interest, with simple examples and in under 200 words each.

What AI shouldn’t do for you

❌ Tell you which stocks or crypto to buy.
❌ Manage your money with access to your bank unless it’s an official tool from the bank itself.
❌ Be your only source on taxes or mortgages: check with a professional or official sources.

Remember that chatbots can get numbers wrong. We explain why in AI hallucinations.
