As of 13 August 2026, AI can calculate your product profit margin.
This still needs a person who signs their name to it.

What the alternative costsA comparable alternative price is not provided in the supplied tool data.
If this goes wrong, you price a product or forecast its profitability using omitted costs or inconsistent VAT treatment.

How to actually do it
- Open your current price list, sales reports, supplier invoices and fulfilment or payment-fee records for the product.
- Gather the selling price and decide whether every figure will be shown inclusive or exclusive of VAT, then record that choice.
- List the per-unit costs for materials, production, packaging, delivery, fulfilment, payment fees, marketplace fees, refunds, discounts, direct labour and any documented overhead allocation.
- Paste the figures into the prompt, including the product name, currency, sales channel and the margin definition or scenarios you want compared.
- Ask the model to calculate gross, contribution and profit margin separately, and to flag every missing or ambiguous input instead of estimating it.
- Compare each drafted input with the source invoices, reports and price list, then recalculate one example manually using the displayed formula.
- Give the result to your accountant for review if the margin will support statutory accounts, investor reporting, tax work or a major pricing decision.
Prompt
Calculate the profit margin for the product data below. Do not invent, estimate or fill in missing figures. First list every input you received and flag missing or ambiguous costs. Keep VAT treatment consistent and state whether the figures are inclusive or exclusive of VAT. Calculate separately where the data allows: gross margin, contribution margin and profit margin. Use these formulas and show the working: margin percentage = (selling price minus relevant cost) divided by selling price multiplied by 100; profit per unit = selling price minus relevant cost. Include the costs only when they are supported by the data, such as materials, manufacturing, packaging, fulfilment, delivery, payment fees, marketplace fees, refunds, discounts, direct labour and an explicitly supplied overhead allocation. Do not treat revenue as profit. Present a table with selling price, each cost, total relevant cost, profit per unit and margin percentage. Then provide a short sensitivity table for the scenarios I specify. End with a list of checks I must make against my accounts, invoices and current price list. Product and pricing data: [paste data here]. Margin definition or scenarios required: [paste here].

What it gets wrong
- AI cannot decide whether an unusual cost belongs in gross margin, contribution margin or profit without your accounting policy.
- AI cannot recover costs that are absent from your records, such as overlooked returns, discounts, wasted stock or shared overheads.
- AI cannot confirm that your VAT treatment, sales-channel deductions and unit conversions match your bookkeeping.
- AI cannot carry responsibility for a price, forecast or financial report based on the calculation.
Even on a YES, the friction has a name: judgement under ambiguity, verification cost and stakes of error.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.
| Axis | Score (0–2) |
|---|---|
| Output | 2 |
| Inputs | 2 |
| Verification | 1 |
| Liability | 1 |
| Effort delta | 2 |

FAQ
- Can ChatGPT calculate my product profit margin?
- Yes, if you provide the selling price and complete, consistently treated cost figures. Ask it to show the working and to flag missing costs rather than estimate them.
- What costs should I include in my product profit margin?
- Start with the costs directly linked to the product and sale, including production, packaging, delivery, fulfilment, payment or marketplace fees, refunds, discounts and direct labour. Add overheads only when you have a defensible allocation method, and keep VAT treatment consistent.
- Is profit margin the same as markup?
- No. Profit margin divides profit by the selling price, while markup divides profit by the cost. Give the model the definition you need and ask it to show both figures if you are comparing pricing documents.
- Can AI set my product price from the profit margin?
- It can calculate prices for a target margin from figures you supply, but it cannot decide whether customers will accept that price or whether your cost assumptions are complete. This is not professional advice, and an accountant should review a serious financial or reporting decision.
