As of 13 August 2026, AI can calculate the profit margin on your quote.

Most people should hand this to a purpose-built tool.

What the alternative costsNo comparable alternative price is provided in the available tool data.

If this goes wrong: you send a quote that appears profitable but omits a material cost, reducing or eliminating your actual profit.

One pick for this task
Copy.ai
Copy.ai supports go-to-market workflows and can help organise quote inputs, but it is not a specialist profit-margin calculator, so a free chat interface remains the more direct option.

Do it yourself

Second choice

A chat interface, chat-fluent skill, and roughly 15 minutes until you can act on the result.

How to actually do it

Open the quote, current price list and supplier or subcontractor cost records for the work being quoted.
Gather the quote price, quantities, discounts, delivery charges, VAT treatment, materials, labour, subcontractor costs, commissions, payment fees and any overhead allocation that your business normally includes.
Paste the figures into the prompt, label every amount as including or excluding VAT, and leave any unknown item blank rather than estimating it.
Ask the model to calculate gross profit and profit margin, and to show markup separately if you use both measures in your business.
Recalculate the displayed formula with a calculator and compare every input against the quote and cost records before sending the quote.
Test the result with realistic changes to the price, quantity and major costs, then save the checked calculation with the quote.

Prompt

Calculate the profit margin on this quote using only the figures I provide. Do not invent, estimate or fill in missing figures. First confirm whether the quote and costs are stated including or excluding VAT, and use the correct basis consistently. Unless I specify another definition, calculate: gross profit = sales price excluding VAT minus total relevant costs excluding VAT; profit margin = gross profit divided by sales price excluding VAT, multiplied by 100. Also calculate markup on cost separately if the figures support it: markup = gross profit divided by total cost, multiplied by 100. Show every input, identify missing costs, show the arithmetic, and state whether any discount, delivery charge, payment fee, commission, subcontractor cost, materials cost, labour cost or allocated overhead has been excluded. Give the result for the base quote and any alternatives I provide. Do not give a confident result where the VAT treatment, units, quantities or cost basis is unclear. Here are the details: [quote price and currency]; [VAT treatment]; [discounts and delivery charges]; [materials and supplier costs]; [labour or subcontractor costs]; [sales commission and payment fees]; [allocated overheads, if applicable]; [quantity and number of units]; [alternative quote prices or scenarios]; [definition of margin required by my business, if different].

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

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

What it gets wrong

It cannot know which overheads, internal labour costs or future costs your business should allocate unless you provide a defined method.
It cannot resolve an unclear difference between margin, gross margin, net margin and markup without your business definition.
It cannot detect a supplier price, tax treatment or quantity that is missing from the information you paste.
It cannot accept responsibility for a quote that is underpriced or commercially unsuitable.

Even on a YES, the friction has a name: judgement under ambiguity and stakes of error.

How we scored this

FAQ

Can ChatGPT calculate the profit margin on a quote?: Yes. Give it the quote price and all relevant costs, state whether each figure includes VAT, and ask it to show the formula and workings. Check the inputs and arithmetic before using the result.
What information does AI need to calculate a profit margin?: It needs the selling price, quantity, discounts and the costs that belong in your definition of profit. Include materials, labour, subcontractors, delivery, commissions, payment fees and any overhead allocation, with the VAT treatment for each.
What is the difference between profit margin and markup?: Profit margin divides profit by the selling price. Markup divides profit by the cost, so ask the model to calculate both if your quote or business uses the terms inconsistently.
Can AI tell me whether my quote is profitable?: It can calculate the result from the figures you provide, but it cannot know whether your cost list is complete or whether your overhead allocation is suitable. You carry the commercial decision and should check the calculation against your records.
