Calculating How Long A Cord Of Wood Lasts
If you’re a wood-burning stove or fireplace owner, you may be wondering how long a cord of wood will last. The answer to this question depends on multiple factors, including the type of wood, how much you use, and the efficiency of your heating appliance.
Average Burn Time For Different Types Of Wood
Different types of wood have different properties, including density, moisture content, and heat value. Some types of wood burn more efficiently, producing more heat per volume, while others burn slower, lasting longer but with less heat output. Here are some average burn times for common types of wood:
- Softwoods (pine, fir, spruce): 1-3 hours per cubic foot
- Hardwoods (oak, maple, hickory): 2-4 hours per cubic foot
- Dense hardwoods (ironwood, eucalyptus, madrone): 3-5 hours per cubic foot
How To Measure Your Usage
To estimate how long a cord of wood will last specifically for your heating needs, you need to measure your wood usage. Here are the steps:
- Measure the length, width, and height of your wood storage area in feet.
- Multiply these numbers together to get the total volume in cubic feet.
- Stack the wood neatly inside the storage area.
- Measure the length, width, and height of the stacked wood in feet.
- Multiply these numbers together to get the total volume of wood in cubic feet.
- Subtract 10% from the total volume of wood to account for gaps between the logs and air movement.
- Divide the adjusted wood volume by 128 to get the total number of cords of wood.
Example Calculations
Let’s say you have a wood storage area that measures 8 feet long, 4 feet wide, and 6 feet high. You stack the wood neatly inside the storage area and measure it again, finding that it measures 7 feet long, 3 feet wide, and 5 feet high.
Here’s how to calculate the number of cords of wood you have:
- Wood storage area volume: 8 x 4 x 6 = 192 cubic feet
- Stacked wood volume: 7 x 3 x 5 = 105 cubic feet
- Adjusted wood volume: 105 – (105 x 0.1) = 94.5 cubic feet
- Number of cords of wood: 94.5 / 128 = 0.74 cords
Now, let’s say you have a wood-burning stove that burns at an average rate of 3 cubic feet per hour and you burn 8 hours per day during a typical winter month. Here’s how to calculate how long a cord of wood will last for you:
- Cord of wood volume: 8 x 4 x 4 = 128 cubic feet
- Cord of wood burn time: 128 / 3 = 42.7 hours
- Daily wood usage: 3 x 8 = 24 cubic feet
- Monthly wood usage: 24 x 30 = 720 cubic feet
- Cord of wood usage per month: 720 / 128 = 5.6 cords
- Cord of wood burn time per month: 42.7 x 5.6 = 239 hours
By following these steps and calculations, you can estimate how long a cord of wood will last for you and ensure you have enough wood to last through the winter season. Happy burning!

Other Faqs About Cordwood Usage
A cord of wood is a common measurement for firewood, but it can be tricky for homeowners to estimate just how much they need. Beyond quantity, there are several common questions about cordwood usage that any responsible firewood owner should consider.
In this guide, we’ll take a look at some common questions about cordwood usage and what you need to know to stay warm and safe during the colder months.
How Much Is A Cord Of Wood?
A cord of wood is a measurement of firewood that is equal to a stack that measures 4 feet high by 4 feet wide by 8 feet long, or 128 cubic feet. In essence, it’s a pile of wood that fits into the bed of a full-size pickup truck.
If you purchase firewood by the cord, it is essential to ensure you get what you’re paying for since a lack of proper measurement can lead to disappointment and shorted loads.
Typically, you should expect to pay a little more for delivery expenses unless you have a reliable truck and extra hands to help load and unload.
How Many Btus Are In A Cord Of Wood?
One cord of wood equals about 22 million btus of heat energy, depending on the kind of wood you choose. Some species of wood, such as oak and hickory, provide more heat per volume than others because they are denser and contain more energy per log than lighter woods like pine.
For reference, dry oak produces about 24 million btus per cord, while birch firewood produces roughly 20 million btus per cord. Calculating heating needs starts with determining the amount of heat per btu needed for your home, then dividing by the amount of heat each cord of firewood generates.
Is It Better To Buy Seasoned Or Unseasoned Wood?
When buying firewood, you have two options: seasoned or unseasoned (green). Dry, seasoned firewood is more expensive than unseasoned, but it will provide more heat per volume of wood since much of the water inside has already left, and it will ignite quickly.
Unseasoned wood, on the other hand, is cheaper, but it contains roughly 50 percent moisture, which makes it difficult to ignite and less effective at heating. As such, seasoned wood is always the better choice for burning in a wood stove or fireplace.
What Are Some Alternative Heating Options To A Wood Stove?
While owning a wood stove or fireplace is an excellent option to stay warm, it’s not the only available method of heating. Here are some alternative heating options to consider:
- Pellet stoves
- Space heaters
- Electric blankets
- Radiant heaters
- Geothermal heat pumps
Keep in mind, however, that each heating method comes with pros and cons, and if you decide to switch from a wood-burning stove, be sure to evaluate your long-term heating needs and costs.
Conclusion
Based on a number of factors, such as the type of wood, storage conditions, and climate, a cord of wood can last anywhere from a few weeks to a year. This highlights the importance of proper storage and seasoning to prevent rot and insect infestation.
While a cord of wood may be costly at first, investing in higher quality wood and ensuring it is properly stored can ultimately save you money in the long run. Additionally, choosing the right fireplace or stove and using it efficiently can also extend the life of your wood.
Ultimately, understanding how long a cord of wood can last and taking steps to maximize its longevity can help ensure a warm and cozy winter season while minimizing waste and expenses. So, whether you’re a seasoned firewood user or new to the game, following these tips and guidelines can make sure your home is comfortable and your heat lasts all winter long.
