As of 13 August 2026, AI can plan your monthly savings contributions.

What to actually do

1. Use a tool built for this

   The route this page recommends

2. Do it yourself

   Second choice

   A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open your current-account statements, payslips, bills and debt statements, and record your after-tax income, pay frequency, regular costs, variable spending and repayments.
   2. List each irregular cost, such as insurance or annual maintenance, with its full amount and how often it occurs, rather than leaving it out of the monthly budget.
   3. Write down your current cash savings, the amount you need to keep available, and each savings goal with its target amount and target date.
   4. Paste the collected figures into the prompt and ask the chatbot to calculate the cautious, balanced and ambitious monthly contributions.
   5. Compare every input and calculation with your statements and bills, then correct the prompt and regenerate the plan for any missing or inaccurate figure.
   6. Choose a contribution that still covers your lowest expected income and irregular costs, set up a standing order after payday, and check the plan against your actual spending after the first full month.

   Prompt

   Act as a cautious budgeting assistant for a UK household. Based only on the information I provide, calculate how much I could save each month and suggest a sustainable contribution rather than the largest possible one. Show the arithmetic clearly and separate fixed costs, variable spending, irregular annual costs, debt repayments, existing savings and discretionary spending. Convert irregular costs into a monthly amount only when I give you the relevant figures. Ask concise follow-up questions before calculating if any essential figure is missing. Produce three options: cautious, balanced and ambitious, explaining the trade-off for each. Keep enough money available for ordinary bills and irregular costs, and flag any month in which my income is lower than my planned outgoings. Do not invent figures, assume missing costs are zero, recommend investments or savings products, or give tax advice. State which figures I must check against my bank statements and bills. Use pounds and UK terminology. Here is my information:
   
   Income after tax and pay frequency: [insert]
   Essential monthly costs: [insert]
   Variable monthly spending: [insert]
   Irregular costs, amount and frequency: [insert]
   Debt repayments and interest details if known: [insert]
   Current cash savings and any emergency reserve: [insert]
   Savings goals, target amounts and target dates: [insert]
   Expected changes to income or spending: [insert]
   Any amount I must keep available each month: [insert]

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
