See which products lost margin after your supplier raised prices
Two pasted price lists turn into a ranked list of the items quietly eating your profit.
Published . Steps as of October 2026.
How can AI show me which products lost profit after a price rise?
Paste your supplier's new price list and your own product list into one chat and ask for a margin table sorted by the biggest drop. ChatGPT, Claude and Gemini all handle this as a single paste. If you only know rough amounts per item, say so, and ask it to flag anything it had to estimate. Check the flagged items against your latest invoice before you change any price on the shelf.

Your prompt
Fill in your details. Skip any you like.
ChatGPT and Claude open with your prompt already typed in. Gemini can't be filled in from a link, so its button copies your prompt: paste it into the new chat.
The prompt that gets copied
I run [YOUR BUSINESS, e.g. a small bakery]. My supplier just sent new prices. Below are two lists. List 1, my supplier's new prices (and old prices if I have them): [SUPPLIER PRICE LIST] List 2, what I sell, my selling price, and roughly what goes into each item: [MY PRODUCTS AND PRICES] Please: 1. Work out what each of my items now costs me to make, using the new supplier prices. 2. Give me a table: item, old cost (if known), new cost, selling price, margin percent, change. 3. Sort it so the items that lost the most margin come first. 4. For each item below [TARGET MARGIN, e.g. 60%], suggest a new price that gets it back to target, rounded to a price customers are used to seeing. 5. Point out any item where a cheaper swap or smaller portion might work better than a price rise. If an amount is missing or unclear, ask me instead of guessing.
Paste your supplier's new price list next to your own prices. You get a table of what each item now costs you to make, your new margin, and a fair new price for the ones that slipped.
Step by step
- Copy your supplier's latest price list from their email or portal
- Copy your own product or menu list with prices and rough ingredient amounts
- Paste both into a new chat with the prompt and fill in your details
- Check the flagged items against your last invoice before you change a price
What you'll get
A sorted margin table showing each item's new cost and margin, plus suggested new prices for the ones that dropped below your target.
