A prompt is the message you send to the AI tool. Copy the one on this page, put your own details where it asks, and read the answer before you act on it.

What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

I make $7,000 a month and my fixed expenses are $4,000, so I have $3,000 left. Create a monthly budget for that $3,000 that covers saving and investing, fun money, debt or big goals and a buffer, and tell me how much I can spend each week.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Split the money left after my fixed bills into a monthly plan I can actually live with.

Questions to ask me first:
- What's your take-home pay and total fixed bills each month?
- What are your top goals (debt, emergency fund, retirement, a big purchase)?
- What surprise costs have hit you in the past year?

Inputs (fill in or confirm):
- Monthly take-home pay: [INCOME]
- Fixed expenses: [FIXED COSTS]
- Goals and current balances: [GOALS]
- Irregular costs I know about (car repairs, gifts, medical): [IRREGULAR COSTS]

Rules:
- Show each bucket as a dollar amount and percent, plus a weekly spending number.
- Size the buffer from my real irregular costs, not a fixed 10%.
- Say which buckets I can borrow from in an emergency and in what order.
- Keep advice general; I'll check investment choices with a professional.

Checkpoint: Show the split and the buffer reasoning, then wait for me to adjust before planning transfers.

If you get stuck: If my goals don't fit the money, show the trade-offs instead of shrinking everything evenly.

Verify before you finish: Confirm that the buckets add up exactly to what's left after fixed bills.

Output: A budget table, a weekly spending number and an emergency plan for surprise costs.

Done when: I have a plan I can follow for a month and adjust from real spending.

Outcome

Laura Beck earns $7,000 a month and spends $4,000 on fixed costs, so Beck asked ChatGPT how to split the remaining $3,000. It suggested a modified 50/30/20 plan: $1,200 to investing and saving, $900 to wants and fun, $600 to debt or big goals and a $300 flex buffer, which left $225 a week to spend freely. In week two the car needed $400 of tires. The buffer covered most of it, but $100 came out of fun money, cutting that week's allowance to $125. Beck then started treating the $600 goal money as partly available for surprises, which ChatGPT hadn't recommended. Four weeks in, Beck had $1,200 in retirement accounts and $300 in emergency savings, and would follow the plan again with changes, especially a flex buffer bigger than 10%.

Evidence: Article or interviewA newsletter, journalist or interview account of what happened.

Known limitations

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: The 10% buffer was too small for one $400 repair, and Beck had to change the plan in a way ChatGPT hadn't suggested.
