Press and data kit
Wood Heat Index estimates what a cord of firewood costs in every U.S. county, and keeps the record. There is no official U.S. firewood price series. Each month we publish a modeled price range for one full cord in every county, say what evidence each range rests on, and archive the month's numbers. Everything here is free to use under CC BY 4.0 with credit.
Numbers you can cite
As of November 2026. Each figure links to the page it comes from, and the same figures are in /api/national.json. They change every month, so please give the month with the number.
| Figure | Value | Where it lives |
|---|---|---|
| Price of one full cord in the middle U.S. county, counting each county by how many homes there heat with wood | $375 | What a cord costs |
| Likely price range in a typical county | $200–$725 | What a cord costs |
| Lowest and highest county estimates | $250–$640 | The county map |
| Counties with an estimate | 3,144 | Browse by state |
How the numbers are made
Every county starts from a model of its climate and how many homes there heat with wood. Real prices move a county's number where we have them: state price surveys, prices on firewood sellers' websites, and prices readers report. Each county shows a likely range, not just one price, and says which kind of evidence it rests on. Where a county has no local prices, its range is wide.
When quoting a figure, please give its range and month, and call it an estimate: a county's number is modeled, not a quote from any seller. Sellers are never named, and seller and reader prices are published only as counts per county. The full method, sources and limits are on the methodology page.
