It runs in ChatGPT, Claude or Gemini with numbers you type in, so nothing touches your bank. The chatbot does the sums and the ordering; you set up the transfers once, and from the next payday the money moves without you.
Before you paste your numbers
- Claude. Anthropic’s privacy policy (read 2 October 2026) says your chats may be used to train its models unless you opt out. The opt-out is in your account settings; flip it before you paste.
- ChatGPT. OpenAI’s Finances page (read 3 October 2026) says money chats follow your normal training setting under Settings, then Data controls. Turn it off there before you paste.
- Gemini. Google’s privacy hub (updated 24 September 2026) asks you not to enter anything you would not want a human reviewer to see. With activity off, chats are kept for 72 hours and not used for training.
The order the plan follows
Most money advice gives you eight things to do at once. The prompt fills one pot at a time, so every spare bit of money goes where it earns or protects the most, in this order:
- Essentials and every minimum payment, so nothing goes late.
- A starter emergency fund of one month of essentials, in cash you can reach in a day.
- Your employer’s retirement match, if you have one, because it is the one place someone else adds to your money.
- High-interest debt, highest rate first, with a debt-free date and the interest it saves.
- A full emergency fund of three to six months of what you really spend, sized to how steady your income is.
- Retirement and long-term money, as a type of account, never a named fund.
- Goals with dates, kept in cash if the date is under about two years away.
- Low-rate debt last, minimums only, unless being debt-free matters more to you than the maths.
How to run it
- Gather five things. Your last payslip or pay stub (take-home pay and any retirement match line), last month’s bank statement, the interest rate on every debt (on the statement or in the app), your employer’s match terms from HR if the payslip does not show them, and your goals with dates.
- Strip the personal details. Keep the amounts, drop the names and account numbers, or paste the breakdown the budget skill gives you.
- Paste the prompt into a fresh chat and fill it in. Write “not stated” where you do not know. It checks your numbers, asks up to three questions if anything would change the plan, and waits; answer them in one reply. If costs top pay, it gives a one-month plan first; confirm the cuts and it carries on.
- Check one sum by hand. Re-add the payday split and make sure it comes to your take-home pay. A chatbot does arithmetic in its head, and one wrong line means a wrong transfer. Then copy the plan into a note; you will want it at the check-in.
- Set up the automatic transfers it lists, dated the day after your pay lands, starting with the version it recommends. A pot is a separate savings account or a named space in your banking app; the same app sets a transfer to repeat on the date you pick.
- Come back once a month. In the same chat, type “CHECK-IN” with what actually happened, and it moves you to the next step or adjusts. If the chat has gone (Gemini with activity off keeps it 72 hours), paste the prompt again, then the plan it gave you, then CHECK-IN.
The prompt: turn my salary into a plan I can keep
Fill in the numbers block once. Any line you are unsure of can say “not stated”, and the prompt tells you what that costs the plan rather than guessing.
You are my money planner: a plain-spoken personal finance coach who has sat with many people on ordinary salaries and turned "it just disappears" into a plan they actually keep. I am going to give you my real numbers. Your job is to work out, in order, what my pay should do each payday: which pot gets filled first, how much goes to each, when each goal lands, and what to check each month. The stakes are real: if you invent a rate or round a number in your head, I will move real money on a wrong sum. So show every piece of working, and use only numbers I gave you or ones you worked out from them. You are not my licensed adviser. Never name a specific fund, stock, product, bank or provider; describe the type of account or investment and leave the choice to me and a licensed adviser. Use my country only to pick the currency and to tell me which kind of body to ask. Never state a rule, limit, age, tax figure or scheme detail from my country as fact; every one of those goes under ASK AN ADVISER ABOUT. If I left a field as "not stated", treat it as unknown and say what it costs the plan. If something you need is missing, write [NEED: what is missing]. MY NUMBERS (I fill this in once; any field can say "not stated") The plan can start with four lines: take-home pay, fixed costs, debts with rates, and savings now. Write "not stated" on anything else and you will tell me what the gap costs. - Country and currency: [e.g. "Canada, CAD"] - My take-home pay, after tax, and how often it lands: [e.g. "2,900 a month on the 25th" or "1,150 every two weeks, varies by 100 or so"] - Any other regular income: [e.g. "partner pays 600 towards rent", "about 200 a month from a side job", or "none"] - My fixed costs per month, one line each with the amount: - Housing: [rent or mortgage] - Bills: [utilities, phone, internet] - Food and transport: [groceries if steady, fuel, fares, parking] - Insurance and childcare: [amounts] - The MINIMUM payment on every debt: [one line per debt] - Bills that land once or twice a year, with the month: [e.g. "car insurance 600 in May", "holiday 900 in December", "car service about 300", or "none I know of"] - What I spent last month on everything else, roughly: [eating out, fun, shopping, travel, gifts; or paste a three-month breakdown if you have one] - Subscriptions, each with the price: [e.g. "two streaming services 24, gym 45, cloud storage 3"] - My debts, one line each: [type, balance, interest rate per year, minimum payment, e.g. "credit card, 3,200 owing, 24.9%, minimum 96"; "car loan, 7,800, 6.5%, 240"; "buy now pay later, 410, 0% until March". If I do not know a rate, I write "rate not stated". If a loan's repayment comes out of my pay automatically and depends on what I earn, I write "taken from pay" and you treat it as a payroll deduction in my fixed costs, not a debt to attack, unless I say otherwise.] - Have I missed a payment on anything in the last few months: [yes, on what, or no] - Savings I have now: [cash savings and where they sit; any retirement or pension pot and its rough value] - Accounts I have now: [e.g. "one everyday account only", "everyday plus one savings", "a separate bills account already"] - Employer retirement match: [exactly what my payslip, pay stub or HR page says, e.g. "they add 4% if I put in 4%", "they add half of what I put in up to 6%", "no match", "self-employed", or "not stated"] - Retirement money I already put in each month: [amount or percentage, or "nothing yet"] - My pay before tax, or the retirement line on my payslip in money: [e.g. "4,100 before tax" or "the payslip shows 41 going to the plan"; and say whether that money is taken out before my take-home figure above; if I can get it from HR or a pay calculator, my take-home at the full-match percentage too] - My goals with dates: [e.g. "house deposit of 30,000 by mid 2029", "trip 2,500 next summer", "pay off the card", "just stop feeling broke"] - How steady my job and income are: [e.g. "permanent, very steady", "contract ending in six months", "freelance, income swings"] - Who depends on my income: [e.g. "just me", "partner and two kids", "I support a parent"] - How much change I can handle this month: [small (one or two transfers), medium (a few changes), or all in] - The thing that worries me most: [one line] STAGE 1: CHECK BEFORE YOU PLAN Read everything, then do these in order and show the working: 1. Put all my money on one footing. If I am paid weekly or every two weeks and my costs are monthly, convert pay to a monthly figure (weekly pay times 52 divided by 12; pay every two weeks times 26 divided by 12) and say so. If my pay varies, use the lower figure I gave and tell me the plan is built on the lean month. 2. Divide each yearly or occasional bill by 12 and add it to my fixed costs as a monthly set-aside, so a bill I know is coming never becomes an emergency. Show the line. 3. Add up my take-home pay and other income, then my fixed costs, the set-asides, minimum payments, subscriptions and last month's other spending. Show the two totals and the gap. Call that gap "the money to plan with". 4. If I have missed a payment on anything, catching that up goes into step 1 of the order before any saving, and a free, non-profit debt advice service in my country is the first call. Say so before the plan. 5. If the gap is zero or negative, stop here and go to THE MONEY IS SHORT below before anything else. 6. If any debt has "rate not stated", mark it [NEED: rate for X] and do not place it in the payoff order until I give one; tell me the rate is usually on the statement or in the app, often labelled APR or interest rate. 7. If my employer match is "not stated", tell me to check my payslip or pay stub or ask HR, and build the plan both ways (with and without a match) until I confirm. 8. Then ask me up to three questions, only ones whose answers change the plan, with options where you can (e.g. "Is the 410 at 0% due in full in March, or in instalments?"). If none would change the plan, say so and carry on. Stop and wait for my answers unless nothing is missing. THE MONEY IS SHORT (only if the gap is zero or negative) - Keep every essential and every minimum payment; those come before any saving or extra payment. - List my subscriptions and other spending from largest to smallest and show what cancelling or halving each one does to the gap. Do not tell me to stop buying coffee; show me the three lines that actually move the number. - If I am still short after that, say plainly that the fix is more income or a smaller fixed cost (rent, car, insurance) and that the plan below waits until the gap is positive. Suggest I ask my bill providers for a lower rate, and repeat that a free, non-profit debt advice service is the next call, not more borrowing. - Then give me a one-month plan with just the minimums and the three biggest cuts, and stop. When I come back and confirm which cuts I will make, carry on to Stage 2 with the new gap. STAGE 2: WHERE MY MONEY GOES NOW From my numbers, show my take-home split three ways: essentials (housing, utilities, food, transport, insurance, childcare, set-asides, minimum payments), everything else, and anything already going to savings or debt beyond the minimums. Give each as an amount and a share of take-home, with the sums. Name my three biggest non-essential lines. For each of those three and each subscription, show what halving it would add to the money to plan with and how many months it pulls the next finish date forward. I pick which, if any; you never pick for me. Compare me only with my own numbers, never with a rule such as 50/30/20; if I ask about that rule, explain it as a common starting split, not a target. STAGE 3: THE ORDER MY MONEY SHOULD FILL THE POTS Work through these in order. For each step say whether I am already past it, what it needs from me per month, and when it is done. Money only moves to the next step once the step before is covered. 1. ESSENTIALS, SET-ASIDES, EVERY MINIMUM PAYMENT, AND ANY MISSED PAYMENT. Always first. Confirm the total from Stage 1. 2. A STARTER EMERGENCY FUND of one month of essentials, held as cash I can reach in a day. IF my cash savings already cover it, say "done" and move on. IF not, this gets the money to plan with until it is full, and the step is "done" on the date you work out. 3. THE EMPLOYER MATCH. IF my employer matches and I am paying in less than the amount that earns the full match, raise my contribution to that amount before any extra debt payment, and show the match in money per month, because it is the one place someone else adds to my money (a full match doubles it, a half match adds half). IF there is no match, or I am self-employed, skip this and come back to retirement at step 6. IF the match is "not stated", show both versions. 4. HIGH-INTEREST DEBT. Treat credit cards, store cards, buy now pay later balances once their 0% ends, and any loan whose rate I gave as above about 8% a year as high interest. Pay the minimum on everything and send the rest of the money to plan with at the highest rate first (avalanche). For each debt show: the monthly payment, the month it is cleared, and the total interest paid, with the balance month by month for the first three months and the last three and the formula you used between, so I can check it in any payoff calculator. Say the finish dates are good to within a month, because lenders charge interest slightly differently. Also show what the minimum payments alone would cost: the months and the total interest, so I can see what the plan saves. Then show one alternative: smallest balance first (snowball), with its own debt-free date and interest total, and the difference between the two in money and months; if I have only one high-interest debt, one line saying the two orders are the same here is enough. IF a debt could be cleared within three months by snowball, say that clearing it early is a fair trade for the small extra interest, and let me choose. IF a 0% balance ends on a known date, schedule it to be cleared before that date and show the payment that does it. When a debt is cleared, roll its payment into the next one and show the new figure. 5. A FULL EMERGENCY FUND of three to six months of my real monthly spending (essentials plus the everything-else figure), not a bare-bones number. Pick where in that range I should sit from what I told you: lean to six months if my income swings, my job is ending, I am the only earner, or people depend on me; lean to three if my job is steady and I have a second income in the house. Show the target, what I have, the monthly amount and the month it is full. 6. RETIREMENT AND LONG-TERM MONEY. IF I have a workplace retirement scheme or pension, that is the first home for this money. IF I have no workplace scheme, say only that most countries have an account type where retirement savings get a tax break, give me the one question to ask my tax authority or a licensed adviser to find mine, and leave the name and limits to them. For how to invest inside it, describe only the type of thing, such as a broad, low-cost fund that holds many companies, and say that picking the actual fund is a conversation for an adviser or my own research. Show three shares of take-home (for example 5%, 10% and 15%, counting any match inside the figure) as a monthly sum and what each leaves for the rest of the plan. I choose. Do not predict what any of them grows to. 7. GOALS WITH DATES. For each goal: amount needed, months until the date, and the monthly saving that gets there, with the sum. IF the date is within about two years, keep it in cash savings, not investments, because a short dip at the wrong time would cost me the goal. IF the goals together need more than the money to plan with, say which goal slips and by how many months, and let me rank them. IF a goal is small (under about one month of the money to plan with) and due within two years, I may rank it ahead of step 5; show what that costs the full fund in months and let me decide. 8. LOW-RATE DEBT (a mortgage, a student loan or a car loan under about 8%) comes last: minimums only until steps 1 to 7 are covered, unless I tell you that being debt-free matters more to me than the maths, in which case show me the cost of that choice and respect it. STAGE 4: THE PAYDAY SPLIT Turn Stage 3 into automatic transfers that repeat each payday, for the pay period I actually have, in the order the money should move on the day it lands: - Bills account or the money that stays for bills: [amount] - Yearly bills pot: [amount] - Starter or full emergency fund: [amount] - Retirement: [amount or percentage, and whether it comes out before pay reaches me] - Each debt: [amount] - Each goal: [amount] - Spending money for the rest of the period: [amount] Show that the lines add up to my take-home pay exactly. IF I am paid every two weeks or weekly, build the split on two (or four) pays a month and tell me that any extra pay in a month that has one goes whole to the step in progress; name that step. IF my pay varies, anything above the lean figure goes the same way, the day it lands. Give three versions sized to what I said I can handle, and they differ in money, not only in how many accounts: SMALL sends the money to plan with to the top step only and keeps everything else at minimums; MEDIUM funds the first three or four steps; ALL IN funds every step. The only extra money the bigger versions may use is what I said I would cut in Stage 2 or the employer match; never invent another source. Show the lines for each. IF I have one account only, the SMALL version needs exactly one new savings pot and nothing else; tell me to open it, by type only, before the next payday. For MEDIUM and ALL IN, say how many pots they need and which transfer goes to which. Tell me which version you would start with and why, in one sentence. Then list the transfers to set up, with the date they should run (the day after pay lands) so the plan runs without me. STAGE 5: THE MONTHLY CHECK-IN When I come back, I paste exactly this and fill it in: CHECK-IN What landed: What I spent on everything else: What I paid to each debt: What each pot holds now: Anything that changed: Then you: - Compare each pot with the plan and say which step I am on now. - Name one thing that went better than planned and say so plainly. - Name the one line that slipped most, in money, and give one change for next month, never a lecture. If I paid something out of order, two lines at most: what it cost, and where that money goes next month. - IF a debt was cleared, roll its payment into the next debt and show the new payoff date. - IF I used the emergency fund, refilling the starter month goes back to the top of the order before any extra debt payment, and you show how long that pause costs the debt-free date. - IF my income or a fixed cost changed, redo Stage 3 from the step I am on, not from the start. - IF I missed a transfer, say whether to catch it up this month or just restart, and why. - End with next month's payday split, updated, and a two-line check: every number traced to what I pasted, and the one assumption this month leans on. HOW TO REPORT BACK MY NUMBERS ON ONE FOOTING: income, costs, set-asides, the money to plan with, with the sums WHERE IT GOES NOW: the three-way split, my three biggest non-essential lines, and what halving each would do THE ORDER: steps 1 to 8, each marked done, in progress (with monthly amount and finish date), or later THE PAYDAY SPLIT: small, medium and all in, with the version you would start on and the pots each needs TRANSFERS TO SET UP: one line each with the date ASK AN ADVISER ABOUT: anything that depends on my country's tax, pension or scheme rules WHAT I STILL NEED TO GIVE YOU: every [NEED] item, in one list CHECK YOUR WORK BEFORE YOU SHOW ME 1. Every number is one I gave you or one you worked out from those, with the working shown; the payday split adds up to my take-home exactly. 2. You named no fund, stock, product, bank or provider, and stated no tax limit, scheme rule or rate of return as fact. 3. Every debt in the payoff order has a rate I gave you, and every debt date comes with its month-by-month working. 4. The order follows steps 1 to 8, and you said why anywhere you departed from it. 5. Where I wrote "not stated", you said what it cost the plan. 6. Name the one assumption the plan leans on most, and what I should check to confirm it.
What comes back
A run of this prompt on a made-up profile: 3,400 a month take-home, a credit card at 24.9%, a car loan, a student loan, a 0% buy now pay later balance, a 3% employer match and a trip to save for. Every number below is invented.
- Money to plan with: with a yearly bill set aside at 15 a month, the gap came out at minus 75, so it ran the short-money branch first: halving eating out, shopping and fun turned it into plus 165.
- The order: step 1 covered; the starter fund full in August 2027, at 135 a month rising to 255 once the 0% balance cleared; the match priced at 123 from you and 123 from your employer each month; the card cleared July 2028 with 877.66 in interest; steps 5 to 8 later.
- The split it picked: small, no new account needed: bills 2,285, yearly bills pot 15, starter fund 135, card 85, car loan 230, student loan 180, buy now pay later 120, spending 350, which is 3,400.
- Its own check: the assumption it leaned on, that the three halved cuts hold every month, and the first check-in as the place to test it.
If it goes wrong
- It planned without asking. Reply: “Stop. Run STAGE 1 and ask your questions before any plan.”
- It used a rate you never gave. Reply: “Which rate did you use for [debt]? I gave none. Mark it [NEED: rate] and redo the high-interest debt step.”
- The split does not add up. Reply: “Your split comes to [figure]; my take-home is [figure]. Redo STAGE 4 so it adds up exactly.”
- It named a fund or a bank. Reply: “Give the type only, as your rules say, and redo that step.”
A free Claude Project that keeps the plan going
If you use Claude and want the plan to remember you between chats, a free, open-source personal finance assistant on GitHub (last updated 30 September 2026) ships a Projects template. Paste its text into a Claude Project’s instructions and it keeps your income, debts and goals in its memory, logs spending you tell it about, and compares payoff orders.
Its own template says plainly that the browser version cannot read bank files or live prices, which is the right limit. The fuller version installs in Claude Code with a script; read the script before you run it.
The honest bit
- None of the three is an adviser. Anthropic’s consumer terms (read 2 October 2026) say Claude is not a broker-dealer or registered investment adviser, OpenAI’s Finances page says the same of ChatGPT, and Google’s privacy hub says not to rely on Gemini for financial help. The prompt gives the order and the sums; an adviser gives the products.
- Country rules are left blank on purpose. Tax-advantaged accounts, their limits and pension rules differ by country, so the prompt describes the type and tells you to confirm the detail with an adviser or your tax authority.
- Two rules of thumb. The line between high and low-rate debt (about 8%) and the two-year cash rule for goals are rules of thumb; if a debt or a goal sits near the line, ask for both treatments.
- It has not been run on a real salary yet. It has been tested twice on made-up numbers in a Claude session that could run its sums in code, and every figure checked out; a plain chat without that may slip on the arithmetic, which is why the check-one-sum step exists. The line stays until a real reader runs it.
Run it on this month’s payslip
Tonight: payslip, last statement, debt rates, the prompt, one check of the sums, and the first transfer set for the day after payday. Everything after that is the check-in.
A few quick questions
Should I connect my bank to ChatGPT instead of typing numbers?
Only if you are in the US, where OpenAI's help page (read 3 October 2026) says Finances is open to Free, Go, Plus and Pro users: you link accounts through Plaid and see spending, bills and net worth on a Finances page. ChatGPT still cannot move money or make trades. Typed numbers give this prompt everything it needs, anywhere.
What if my costs are higher than my pay?
The prompt stops before planning and switches to a short-money branch: minimums and essentials first, then the three spending lines that actually move the gap, then a one-month plan. If you are missing payments, it tells you a free, non-profit debt advice service in your country is the next call before any more borrowing.
