Firewood cord and price calculator
How many cords are in my woodpile, and what should I charge per cord or per bundle?

Cords

- Face cords at this piece length

- One face cord, as a share of a cord

Measure a stack that is tight and even, with the pieces parallel and touching. A loose or thrown pile holds less wood in the same space.
This calculator counts a face cord as a stack 4 feet high and 8 feet long, one piece deep. How much wood that is depends on the piece length, so it is shown as a share of a full cord.
NIST Handbook 130, the model law many US states adopt, says firewood is sold by the cord, part of a cord or the cubic meter, and that terms such as "face cord", "rack" and "pile" are not used to sell it. Ask your state's weights and measures office what applies where you sell; in the UK, your local Trading Standards office.
Bundles per cord (or per cubic meter)
—
- Price per cord (or per cubic meter)
- —
- Bundles per cord (or per cubic meter)

The same handbook says packaged firewood under 16 cubic feet states its quantity in liters, and may add cubic feet.
Prices and charges are rounded up to the cent, so you never charge less than your rate.

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: How many cords are in my woodpile, and what should I charge per cord or per bundle?"
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
A cord is 128 cubic feet of wood ranked and well stowed: pieces parallel, touching and stacked tight (NIST Handbook 130, 2026, Method of Sale of Commodities 2.4.1.2, doi.org/10.6028/NIST.HB.130-2026). Cords are the stack's length times its height times its depth, in feet, divided by 128; in meters, the cubic meters divided by 3.624556363776, since a foot is exactly 0.3048 m. This calculator counts a face cord as a stack 4 feet high and 8 feet long, one piece deep, so it is the piece length in inches divided by 48 of a cord, and the face cords in a stack are its cords times 48 divided by the piece length. A bundle's price is the price per cord times the bundle's cubic feet divided by 128, plus any wrap, rounded up to the cent; in meters, the price per cubic meter times the bundle's liters divided by 1,000. A charge to split or stack is the cords times your hours per cord times your rate, plus fuel and wear per cord, rounded up to the cent.
A worked example
Example numbers only; use your own. A stack 8 feet long, 4 feet high and 4 feet deep is 128 cubic feet, which is 1 cord, or 3.625 cubic meters. In pieces of 16 inches, that is 3 face cords, each a third of a cord. At 300 a cord, a 0.75 cubic foot bundle comes to 1.76. A bundle sold at 7.00, less 1.00 for the wrap, comes to 1,024.00 a cord. Splitting 4 cords at 2.5 hours a cord and 30.00 an hour, with 10.00 a cord for fuel and wear, is 340.00.
