AI can turn a messy list of bills and spending into a simple monthly budget, show where money slips away, and even build the spreadsheet for you. You never need to share an account number.
Round everything to the nearest 10 or 50. A budget doesn’t need exact numbers, and rounding keeps your details private.
Write them down roughly, in any order. No account numbers, no bank names needed.
Paste your list into the first prompt below. The AI sorts it into categories and shows what’s left over.
Use the spreadsheet prompt to get a ready-made sheet for Google Sheets or Excel, with formulas.
Ask where money is slipping away, and which subscriptions you could pause.
Once a month, paste in what you actually spent and ask what changed.
Start here:
Help me make a simple monthly budget. My take-home pay is about [amount] a month. My regular bills are: [housing, utilities, phone, insurance, loans, subscriptions, with rough amounts]. I usually spend about [amount] on groceries, [amount] on eating out, [amount] on gas or transit and [amount] on everything else. Put this in a table with categories, show what’s left over each month, and point out the 3 categories where I could most easily save. Be practical, not judgmental.
AI is good at building spreadsheets and explaining formulas step by step:
Create a monthly budget spreadsheet for [Google Sheets / Excel]. Columns: Category, Planned, Actual, Difference. Rows for: [your categories]. Give me the exact formulas for the Difference column and a Total row, and tell me which cell to paste each one into.
Here are my spending categories from last month, rounded: [list]. Group them into needs, wants and savings, and show the percentage of my take-home pay for each. Compare it with the common 50/30/20 rule of thumb, then suggest two small, realistic changes.
Here’s a list of my subscriptions and memberships with what each costs a month: [list]. Help me decide which to keep, pause or cancel by asking me one quick question about each.
Many budgets break on costs that don’t come every month. Turn them into a small monthly amount:
List expenses people often forget to budget for, like car repairs, gifts, school costs and yearly fees. Then help me work out a monthly amount to set aside, based on these yearly costs: [list with rough amounts].

Yes. Give it your rough income, bills and spending, and it can sort them into a budget table, suggest savings and build a spreadsheet. You still decide what goes in the plan.
Share rounded totals by category, not account numbers, card numbers, passwords or full statements. That gives the AI everything it needs for a budget without exposing your accounts.
Some budgeting apps can, with your permission. For a simple start, you don’t need that: type in rounded numbers yourself and keep your accounts separate from the chat.
A common rule of thumb that puts about half of take-home pay toward needs, 30% toward wants and 20% toward savings or paying down debt. It’s a guide, not a requirement; many households adjust it.
ChatGPT, Gemini, Claude and Copilot all handle the prompts on this page well. If you use Google Sheets or Excel, the AI built into those apps can also help with formulas.
