Tiller is an extraordinary financial tool — but most people are barely scratching the surface of what it can do. The difference between mediocre results and remarkable results often comes down to one thing: the quality of your prompts.
A vague prompt like “help me with my budget” will give you generic advice. A specific, context-rich prompt will give you a personalized, actionable plan. This guide gives you 50+ proven prompts organized by financial topic, ready to copy and use immediately.
How to Write Better ChatGPT Finance Prompts
Before the prompts themselves, a few principles that make all the difference:
- Include your numbers: “I earn $3,800/month” is infinitely more useful than “I earn a decent income”
- Provide context: Your situation (single/family, debt/no debt, renter/homeowner) changes the advice significantly
- State your goal: What do you want to achieve? Be specific — “save $500/month” vs. “save more”
- Ask for specific output: “Create a table,” “Give me a step-by-step plan,” “Write a script I can use”
- Follow up: ChatGPT improves with iterations — ask it to refine, adjust, or go deeper
Budgeting Prompts
1. Create a complete monthly budget
“I take home $[X]/month. My fixed expenses are: rent $[X], car payment $[X], insurance $[X], subscriptions $[X]. Please create a complete zero-based budget that allocates every dollar and includes savings, dining, groceries, entertainment, and any other relevant categories.”
2. Analyze my current spending
“Here are my transactions from the past month: [paste transactions]. Categorize each one, calculate total spending by category, and identify which areas I’m overspending compared to typical recommendations for someone earning $[X]/month.”
3. Find money I’m wasting
“Review these expenses and identify: (1) any subscriptions I might have forgotten about, (2) categories that seem high compared to national averages, (3) the top 3 areas where small cuts could make a big difference.”
4. Create a budget by percentage
“I’m a freelancer with variable income. Create a percentage-based budget template I can apply to any monthly income level. Organize it so that the first 25% always goes to taxes, then prioritize needs, then savings, then wants.”
5. Compare budget scenarios
“Show me three different budget scenarios for someone earning $[X]/month: (1) aggressive savings mode — maximizing savings/investment, (2) balanced mode — comfortable living with solid savings, (3) debt payoff mode — eliminating $[Y] of debt as fast as possible.”
Savings Prompts

7. Emergency fund calculator
“My monthly essential expenses are: rent $[X], food $[X], utilities $[X], transportation $[X], insurance $[X]. Calculate my 3-month and 6-month emergency fund targets. Then create a 90-day plan to reach the 3-month target from zero.”

Debt Payoff Prompts
11. Create a debt payoff plan
“I have these debts: Credit Card A ($[balance], [APR]% APR, minimum payment $[X]); Student Loan ($[balance], [APR]% APR, minimum $[X]); Car Loan ($[balance], [APR]% APR, minimum $[X]). I can put an extra $[Y]/month toward debt. Show me both the Avalanche and Snowball payoff schedules, total interest for each, and months until debt-free.”
12. Credit card payoff timeline
“I have a credit card balance of $[X] at [APR]% APR. Show me: how long it takes to pay off at minimum payments only, how much I’d pay in total interest, and how those numbers change if I pay $[Y] extra per month.”
13. Balance transfer evaluation
“I have $[X] in credit card debt at 24% APR. There’s a balance transfer offer at 0% APR for 18 months with a 3% transfer fee.
