As of 13 August 2026, AI can calculate the day rate you should charge as a UK freelancer.

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, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open a spreadsheet or notes document and record your target annual personal income, annual business costs, planned reserve for holidays and gaps, and the number of working days you expect to have available.
   2. Estimate how much of that available time will be billable after marketing, administration, sales, training and unpaid client discussions, and record the estimate separately from your total working time.
   3. Write down your service, experience, specialisms, usual client type, project length, current rate if you have one, and the lowest rate you would accept.
   4. Gather comparable UK freelance rates from recent job adverts, professional networks, published rate cards or conversations with relevant freelancers, and paste the figures and links into the chatbot.
   5. Paste the copyable prompt and your recorded information into a chatbot, then ask it to calculate a minimum sustainable rate, a target rate and the assumptions behind each.
   6. Copy the calculation into your spreadsheet and check each operation using your own figures, including the billable-day assumption and the distinction between business costs and personal income.
   7. Compare the suggested target rate with your comparable UK evidence and your actual experience, then adjust the rate for the value, urgency, complexity and risk of the specific client brief.
   8. Put the chosen rate, scope, payment terms, revision limits and any expenses into a written quote, and send that quote only after checking it against your current costs and minimum acceptable rate.

   Prompt

   Act as a practical UK freelance pricing analyst. Calculate the day rate I should consider charging from the information below, but do not present the result as a fact or as professional advice.
   
   My details:
   - Freelance service and typical deliverables: [describe]
   - Experience and specialisms: [describe]
   - Target annual personal income before personal tax: £[amount]
   - Annual business costs: £[amount]
   - Annual amount I want to reserve for holidays, sickness and gaps between contracts: £[amount]
   - Working days available in a year: [number]
   - Estimated non-billable days or time for marketing, administration and sales: [number or percentage]
   - Current day rate, if any: £[amount]
   - Minimum rate I would accept: £[amount]
   - Typical project length and client type: [describe]
   - Evidence from comparable UK freelance rates or recent job adverts: [paste links, figures or say none]
   
   Show the calculation in plain English. Separate the minimum sustainable rate from a target commercial rate and an optional premium rate. State every assumption, use only the figures I provide, and do not invent market data. Explain how the result changes if my billable days, costs or income target change. Check the arithmetic twice. Identify which parts are objective calculations and which parts require my judgement. Finish with a short list of questions I should answer before sending a quote to a client.

   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.
