• Delivered pile

  Firewood Cord Calculator

  Whether a delivery is really a cord, what it cost per cord, and how much heat is in it. Uses the legal 128-cubic-foot definition, flags terms a seller may not use, and shows the solid-wood assumption every published table hides.

  Check a delivery
• Season ahead

  Firewood Consumption Calculator

  How many cords a winter takes, read off your propane, oil, gas or electricity bill — or estimated from your floor area and your state’s real heating degree days. Compares species, and shows what the wood saves against the fuel it replaces.

  Cord of Wood Weight Calculator

  How much a cord or face cord weighs for 146 species, green or seasoned, how much of a green load is water, and how many trips your truck needs at the capacity on its door-pillar label.

  Weigh a cord
• Before you buy

  Face Cord Calculator

  How much of a real cord a face cord is for your piece length, what its price comes to per full cord, and which of two offers gives more heat per dollar once species is counted.

• Before you burn

  Firewood BTU Chart

  Heat per cord for 146 species, softwoods included: the heat in the wood and the heat your stove delivers, why BTU charts disagree by half, and the minimum heat lost burning green wood.

  Compare species
• Before you buy

  Cord of Wood Price Calculator

  What a cord costs in the one official price survey we found, how that price has moved since 2022, and whether a quote beats oil, propane or a heat pump once your stove is counted.

What do they have in common?

• Each one names the definition or published rule it applies, and cites where that definition comes from.
• Eight tools accept US and metric measurements. Firewood Consumption is US-only because its climate inputs are per US state.
• If a required entry is invalid, the new layout tools show a dash instead of a plausible result and disable export.
• Each tool can print or export a CSV result.
• All the arithmetic runs in your browser. Nothing you type is sent anywhere.
