A budget prompt that starts from what you actually spend

Ask your AI to build the budget from three months of real spending, not from a template. A good prompt has it separate fixed bills, flexible spending, and once-a-year costs, ask what you want to protect, and show the tradeoffs in dollars. Copy the prompt below into ChatGPT, Claude, or the agent you use.

The prompt: What budget could I actually live with?

Copy the prompt into the AI agent you use with Candor. It works from your Candor records and asks for anything it's missing. New to Candor? Connect your agent first.

Your prompt

Build me a monthly budget from what I actually spend in Candor. Separate recurring obligations, flexible spending, and irregular expenses. Ask what matters to me and what I want to change. Save it in Candor and tell me the amounts, assumptions, and tradeoffs.

Nothing runs until you send the prompt to your agent.

New to Candor? Set up and start in one message

Paste this into Claude, ChatGPT, or the agent you use. It sets up Candor and walks you through approving its access and connecting your accounts, then runs the prompt from your records.

Set up Candor from https://candor.money/START.md and walk me through connecting it here. Build me a monthly budget from what I actually spend in Candor.

Not on Candor yet? Versions for ChatGPT and Claude.

Both versions work from what you attach, and the budget lives in that chat. With Candor, your agent reads every connected account, saves the budget where you can see and change it, and each week Candor's review raises a category running hot or a yearly bill coming up. The next conversation starts from the plan, not from scratch.

For ChatGPT

Build me a realistic monthly budget from my actual spending. Use the accounts I've connected in ChatGPT if there are any; otherwise use the CSV of my last three months of transactions that I've attached. Separate fixed bills, flexible spending, and costs that come once or twice a year. Leave out transfers between my own accounts and credit card payments so nothing is counted twice. Before you suggest cuts, ask me what I want to protect and what I'd like to spend less on. Then show each category with its recent average and your proposed amount, and tell me what I'd be giving up.

For Claude

I've attached three months of transactions as a CSV. Build me a realistic monthly budget from what I actually spend. First check which months the file covers and flag any month that looks unusual. Separate fixed bills, flexible spending, and once-a-year costs, and leave out transfers and card payments. Ask me up to three questions about what matters to me before proposing amounts. Give me a table with each category's recent average and the proposed amount, the total against my take-home pay, and the tradeoffs in plain words.

What will the agent ask you?

A good agent asks before it answers. Expect questions like these, and answer the ones that matter to you.

  • What's your take-home pay each month, and is it steady?
  • What do you want to protect, even if something else has to give?
  • Is there anything you'd like to spend less on?
  • Were any of the last three months unusual, like a trip, a move, or a medical bill?
  • What comes once or twice a year: insurance, gifts, registration, annual subscriptions?
  • Are you saving toward something the budget should make room for?

What does a good answer look like?

A worked example on sample data: two adults with $6,400 a month in take-home pay, $5,000 in savings, three months of connected history, and car insurance that renews every November.

You

Can you make me a budget I'll actually stick to? Last time I gave up after a month.

Your agent

I looked at July through September. You spend about $6,250 a month, and $3,100 of it is fixed: rent, utilities, phone, and the car payment. September had $610 of dining out against about $380 the two months before, so I didn't treat it as normal.

Your agent

You said groceries and the gym stay, and takeout is where you'd rather cut. This version keeps both and leaves $400 a month to save. The $1,140 car insurance renewal comes in November, too soon for a monthly set-aside to cover it, so I'd pay this one from savings. After that, $95 a month covers next year's bill before it renews.

Your agent

It only works if dining out comes down to about $350. If that feels too tight, we can take $50 from shopping instead. I saved this budget in Candor; tell me what to change.

What Candor's weekly review raises for this household

Once a week, Candor reads the records and notes and raises what's worth talking through, with why it matters and the records behind it. These are the areas it would raise from the sample records. Your agent brings each one up with you and works out the figures.

  • Groceries are running ahead

    Two weeks into October, Groceries is on pace to pass its budget well before the month ends.

    Two weeks in, groceries are running well ahead of the budget. Your agent asks whether it's a one-off, like hosting family, or whether the number was too low, while there's still time to adjust this month.

  • Car insurance renews soon

    The yearly car insurance charge last came on Nov 8, so the next one is due in a few weeks.

    Once-a-year bills are what usually break a budget. Candor brings this one up before it renews, so your agent can check the money for it is ready.

The review also names what would change the picture. Your agent may ask about: what the savings is set aside for; whether either of you has income that isn't connected.

What does a weak answer look like?

Here's a budget using the 50/30/20 rule: 50% of your income for needs, 30% for wants, and 20% for savings. On $6,400 a month, that's $3,200 for needs, $1,920 for wants, and $1,280 for savings.
  • It never looked at what you spend, so it can't say which numbers will hold.
  • It asked nothing about what matters to you, so any cut is arbitrary.
  • Once-a-year bills are missing, and they're what usually breaks a budget.
  • Nothing is saved, so next month starts from zero.

Build from a representative stretch of spending

A budget is easier to assess when the starting point resembles your actual life. Have your agent check the period covered in Candor, separate regular obligations from flexible spending, and flag unusual months. Then tell it what you want to protect or change. The proposal should make those choices visible in exact amounts.

Check the answer

  • Include irregular expenses that may be missing from a single month. Check transfers and card payments so the same spending is not counted twice.
  • Review each proposed category and the total against income and commitments. Ask how an unusual month or missing account affects the draft.

Choose a next step

Your agent saves the version you settle on in Candor and tells you what it saved. Candor's weekly review compares new activity with that plan and raises it when the amounts stop fitting.

Where Candor fits

Your agent works through the question with you, builds the plan, and keeps you on it. Candor gives it your real accounts, exact figures, and the goals, budget, notes, and decisions from earlier sessions, in whichever agent you use. Every week its review raises what's worth talking through and tells your agent why. Candor is not a licensed advisor and gives no advice; your agent does the advising, and the decisions are yours.

  • Read-only: Candor cannot move money.
  • Candor never sells your financial data or trains models on it, and you can export or delete it.
  • Every agent read and change is recorded with its reason.

Common questions

What's the best ChatGPT prompt for budgeting?
One that gives it your real numbers and tells it to ask you questions. Name the months to use, have it separate fixed, flexible, and once-a-year costs, leave out transfers, and show the tradeoffs. A prompt with no data gets a template back.
Can ChatGPT or Claude build a budget from my bank statements?
Yes, if you export your transactions as a CSV or paste them in. Check that the file covers full months and that card payments and transfers aren't counted as spending. Without somewhere to save it, the budget stays in that conversation.
How many months of spending should a budget use?
Three is a reasonable start: enough to smooth out one odd month, recent enough to match your life now. Add once-a-year bills separately, since three months can miss them.
Does Candor make the budget?
Your agent makes it with you. Candor gives it your records and exact totals, saves the budget you settle on, and tells your agent when a category runs hot. Candor is read-only and never moves money.

Ask it with your own numbers.

Connect your accounts to Candor, then send this to the agent you already use. It answers from your real records and keeps the plan for next time.
