The store's cut is rounded to the cent and the maker gets the rest, so the two always add up to the shelf price.
Use the percent and fee in your written agreement. This calculator does not say what split is fair or usual, and leaves out charges that do not depend on sales, such as a monthly rent.
Shelf price

- Maker's payout at that price

Use this calculator in an AI chat
You can ask Claude, ChatGPT or another AI app to work this out for you, and this calculator opens right inside the chat. You connect TallyTill to your AI app once. It is free, and there is no account and no sign-in.
AI apps call add-ons like this connectors, apps or MCP servers. They all mean the same thing: a way for the AI to use a tool someone else made.
1. Copy this address
2. Add it to your AI app
Claude (claude.ai and the Claude desktop app)
- Open Customize, then Connectors.
- Press + Add, then Add custom connector.
- Name it TallyTill calculators, paste the address and press Continue.
- Under Authentication choose No sign in, then press Add.
- In a new chat, press + at the bottom left, choose Connectors and switch TallyTill calculators on.
On Claude's free plan you can add one custom connector.
ChatGPT
- In Settings, turn on Developer mode. OpenAI moves this switch from time to time; it is usually with the settings for apps and connectors.
- Add a new connector (ChatGPT may call it an app), paste the address and choose No authentication.
- In a new chat, choose TallyTill from the tools menu, or type @ and pick it.
Not every ChatGPT plan lets you add your own connector. If you cannot find the option, your plan may not include it.
Using another AI app? Look in its settings for MCP, add the address as a remote server, and choose no sign-in.
3. Ask your question
Say "use TallyTill", so the AI uses the calculator instead of doing the sum itself. For example:
"Use TallyTill: What does the maker get from a consignment sale, and what shelf price pays them what they want?"
What you will see
- The calculator opens in the chat with the numbers you gave already filled in. Change any number and the answer updates.
- If a number is missing, the box is highlighted, or the AI asks you for it in plain words.
- The answer links back to this page, so you can check the working.
- The first time, your AI app asks if it may use TallyTill. Choose Allow.
The calculators take numbers only. They never ask for your name, your email or a password.
How this is worked out
The store's cut is the shelf price times its percent, divided by 100, rounded to the cent. The maker gets the shelf price less the store's cut and any fee per item, and the store keeps the rest. For the items sold, the maker's total is their payout per item times the items, and the store keeps the shelf price times the items less that. The shelf price for a payout is the payout plus the fee per item, divided by 1 less the store's percent over 100, rounded up to the cent.
A worked example
Example numbers only; use your own. A jar of honey sells at 8.00, and the farm stop keeps 30 percent plus 0.25 a jar. The store's cut is 2.40, so the maker gets 5.35 and the store keeps 2.65, which is 66.88 percent of the price to the maker. For 24 jars the maker is paid 128.40 and the store keeps 63.60. A maker who wants 6.00 a jar on the same terms needs a shelf price of 8.93.
