As of 13 August 2026, AI can calculate postage into your product price.

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

What the alternative costsThe available commercial alternative is Rows, a spreadsheet with built-in AI analysis and live data connections.

If this goes wrong: you undercharge for some orders and absorb the difference until you correct the price.

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 your current product-cost sheet and record the unit cost, packaging cost, current price, VAT treatment and target margin or markup for each product.
    2. Open your courier or fulfilment account and copy the current postage rates, parcel-size rules, weight bands, destination zones, surcharges and delivery services into a single document.
    3. List the destinations and order patterns that matter, including whether customers buy one item or several items per order and whether you offer free delivery above a threshold.
    4. Paste the prompt into a chatbot, replace every bracketed slot with your figures and rates, and ask it to calculate the included-postage prices and show the working.
    5. Copy the resulting formulas and table into your pricing spreadsheet, then compare every postage figure and product cost against the source rates and your current price list.
    6. Test the calculation with a single-item order, a multi-item order and the highest-cost delivery case, correcting the prompt or spreadsheet where the included price would undercharge you.
    7. Publish the approved prices and delivery wording only after you have chosen whether postage is included, shown separately or charged by destination.

    Prompt

    Calculate how to include postage in my product price for a UK business. Use only the information I provide and do not invent carrier rates, taxes, packaging costs or margins. If anything is missing, list it as an input needed rather than estimating it.

Product cost per item: [£ amount]
Packaging cost per item: [£ amount]
Postage rates by service, parcel type and destination: [paste rates]
Expected destinations and order mix: [describe]
VAT treatment: [VAT registered, not VAT registered, or unsure]
Target gross margin or markup: [rule]
Current product price: [£ amount]
Whether postage is shown separately or included in the price: [describe]
Any free-shipping threshold or delivery surcharge: [rule]

Produce:
1. A clear formula showing how the product price is calculated.
2. A table for each delivery service or destination band.
3. The resulting price before and after postage is included.
4. A sensitivity table for the postage cases I supplied, without inventing extra scenarios.
5. A list of assumptions and missing inputs.
6. A short recommendation identifying which pricing choice is simplest for customers and which creates the least risk of undercharging.

Keep product price, postage, packaging, VAT and margin separate in the calculation. Flag any decision I must make rather than making it silently. Make all monetary figures clearly identifiable as pounds and show enough working for me to check each result.

    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.

What it gets wrong

  • It cannot know whether your pasted courier rates are current or whether a surcharge applies to a particular parcel.
  • It cannot choose your commercial policy for free delivery, regional exclusions, returns or unusual orders without your decision.
  • It can apply a margin formula consistently but cannot judge whether the resulting customer price is acceptable for your market.
  • It does not replace a live ecommerce shipping calculator that applies carrier rules at checkout.
  • It cannot take responsibility for losses caused by publishing an underpriced product.

Even on a YES, the friction has a name: real time truth, context depth and judgement under ambiguity.

FAQ

Can ChatGPT add postage to my product price?
Yes. Give it the product cost, packaging cost, postage rates, VAT treatment and pricing rule, and ask it to show the calculation rather than only giving a final price. Check the output against your courier rates before publishing.
Should I include postage in my product price?
AI can compare included postage with separate delivery charges using your figures, but the choice is yours. Include the delivery rules, destinations, order sizes and free-shipping policy so it can show where each option would undercharge you.
Can AI calculate shipping costs for different products?
Yes, if you provide the weight, dimensions, packaging and delivery rates for each product or parcel type. It cannot supply reliable current rates or identify hidden carrier surcharges unless you provide a verified source or connected data.
How do I calculate a product price with postage and VAT?
Ask AI to keep product cost, packaging, postage, VAT and margin as separate lines and to show the formula for each result. Confirm the VAT treatment with your records or an accountant if the figures affect a serious pricing decision, as this is not professional advice.
