Can ChatGPT calculate a break-even price?

Yes. Give it fixed costs, variable cost per sale, expected sales volume, selling fees and VAT treatment, and ask it to show the formula rather than only the answer. Check every input against your accounts because the result is only as sound as the costs and assumptions supplied.

What information do I need to calculate a break-even price?

You need the fixed costs for the relevant period, the variable cost of each sale and the number of units you expect to sell. Include payment fees, commissions, discounts, refunds, returns and whether the price is shown including or excluding VAT.

Is an AI break-even calculation accurate?

The arithmetic can be accurate when the inputs and formula are correct. It cannot confirm that you included every relevant cost or that your expected sales volume is realistic, so reproduce the calculation in a spreadsheet and compare the inputs with your records.

Should I ask an accountant to check my break-even price?

Ask an accountant or management accountant to check it when the price affects a serious business decision, involves complex cost allocation or depends on uncertain VAT treatment. AI can prepare the calculation, but it is not professional advice and you retain responsibility for the pricing decision.

YES

As of 13 August 2026, AI can calculate a break-even price.

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

If this goes wrong, you can set a price below your true cost and lose money until the error is found.

Rows combines a spreadsheet with built-in AI analysis, so you can calculate the break-even price and keep the inputs and formulas visible for checking.

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 your accounts, supplier quotes, payment-provider statements, current price list and sales forecast for the product or service.
List the relevant fixed costs for the period and the variable cost of one sale, separating costs that change with volume from costs that do not.
Record expected units sold, VAT treatment, payment fees, marketplace commissions, discounts, refunds and returns, and mark any figure you do not know rather than guessing.
Paste the figures into the prompt and ask the chatbot to calculate the break-even price and show every formula and assumption.
Copy the stated formula into a spreadsheet, enter the same inputs, and compare the result with the chatbot's calculation.
Compare every input against the source documents, correct any missing cost or VAT treatment, then send the final calculation to a colleague or accountant if the price affects a material business decision.

Prompt

Calculate the break-even price for this product or service using the information below.

Business context: [describe the product, service and sales channel]
Currency: GBP
Fixed costs for the relevant period: [list each cost and amount]
Variable cost per unit or sale: [list each cost and amount]
Expected units sold in the relevant period: [number]
Selling fees, commissions, payment fees, discounts, refunds and returns: [list each item and how it applies]
VAT treatment: [state whether the price should be shown including or excluding VAT, and the VAT assumption if known]
Target profit, if I want a price above break-even: [amount or leave blank]

Do not invent or silently estimate any figure. First list the inputs you used and identify missing or ambiguous information. Then calculate:
1. the break-even sales volume at the proposed price, if a proposed price is provided;
2. the break-even price at the expected sales volume;
3. the price needed to achieve the target profit, if supplied.

Show the formula and each calculation in a table. Separate fixed costs, variable costs and selling fees. State whether each result is per unit and whether it includes VAT. Run clearly labelled scenarios for any assumptions I provide, but do not choose an assumption on my behalf. End with a short list of checks I must make against my accounts and current price list. This is a commercial calculation, not professional advice.

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

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.

What it gets wrong

AI cannot decide which indirect costs should be allocated to this product or service without your business context.
AI cannot know whether your sales forecast, return rate or discount assumption is realistic.
AI cannot detect a missing cost unless you provide enough information for it to question the omission.
AI calculates the break-even point but does not decide whether customers will accept the resulting price.
The commercial consequence remains yours if the calculation is wrong. This is not professional advice.

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