Free Tree Value Calculator - Timber Stumpage Estimator
Estimate the commercial timber value (stumpage) of a standing tree from trunk diameter at breast height (DBH) and species.
Enter DBH and species to estimate the standing timber value.
A standing tree can look valuable for two very different reasons. It may have commercial timber value because a buyer can cut, haul, and mill it into lumber. It may also have landscape value because it shades a house, anchors a yard, screens a road, or contributes to the character of a property. The Tree Value Calculator focuses on the first kind: rough stumpage value, which is the value of timber while it is still standing on the stump.
That distinction matters. A mature oak beside a patio may be worth far more to the homeowner than it is to a logger. A straight black walnut in a manageable woodlot may have real timber value, while an equally large tree wedged between a garage, a fence, and utility lines may be expensive to remove and unattractive to a timber buyer. The calculator gives you a screening estimate, not a sale price, insurance appraisal, or arborist report.
Use it when you want a fast, defensible starting point from two inputs you can usually identify: trunk diameter at breast height and broad species group. Then treat the result as a prompt for better questions: Is the tree merchantable? Is access practical? Are local buyers paying well for this species? Is the tree worth keeping for shade, habitat, or landscape function instead?
The calculator estimates commercial stumpage value for one standing tree. In timber language, stumpage is the value of standing timber before it is cut and delivered. Michigan State University Extension describes stumpage as the dollar value of standing trees and notes that it is the first financial benchmark in the forest products chain standing trees.
The output is built for early screening. It helps you compare a 14-inch maple with a 24-inch oak, or a generic hardwood estimate with a black walnut estimate, before you spend time calling buyers or paying for an appraisal. It is especially useful when you are deciding whether a tree is even worth investigating as timber.
It does not estimate replacement cost, shade value, carbon value, wildlife value, stormwater value, sentimental value, or the cost of removal. Those are real values, but they belong to different appraisal methods. The International Society of Arboriculture’s Guide for Plant Appraisal emphasizes appraisal concepts for amenity plants and environmental or ecological benefits, which is a different problem from estimating what a timber buyer might pay plant appraisal.
Stumpage value asks, “What might a buyer pay for this tree as raw timber, after accounting for cutting, hauling, risk, and market demand?” Landscape value asks, “What is this living tree worth in place?” Those numbers can point in opposite directions.
For a yard tree, the timber number is often the smaller number. Urban and residential trees may contain metal, hidden decay, embedded wire, old pruning wounds, branching too low for clear logs, or access problems that make conventional logging impossible. Even if the wood is beautiful, a logger has to move equipment safely, avoid structures, protect pavement, and haul a small volume. Those costs can erase timber value.
For a woodlot tree, the timber number can be more meaningful because the tree may be part of a larger sale. Buyers prefer efficient work: enough volume, enough quality, and enough access to justify mobilizing equipment. North Carolina State Extension lists species, tree quality and size, product type, acreage, location, site conditions, markets, and contract provisions as factors that affect stumpage price stumpage prices.
The calculator uses trunk diameter at breast height, usually shortened to DBH, and a species multiplier. DBH is the standard forestry measurement because diameter near the base can be distorted by root flare and diameter higher in the trunk can miss the standard comparison point. Portland’s urban forestry guidance defines DBH as tree diameter measured 4.5 feet above the ground 4.5 feet.
Species matters because mills and buyers do not pay the same amount for every tree. Black walnut, white oak, red oak, maple, cedar, pine, and mixed hardwoods can occupy very different markets depending on region, log quality, and current demand. The calculator simplifies this into broad multipliers: black walnut at the premium end, oak and cedar in the middle, maple somewhat lower, pine lower as a general softwood estimate, and a generic option for uncertain or mixed hardwoods.
The simplified model is intentional. Most homeowners and small woodland owners do not know merchantable height, log grade, defect percentage, mill specifications, or current delivered log prices. A two-input estimate is less precise than a forester’s cruise, but it is easier to use honestly.
Measure DBH before you do anything else. Use a diameter tape if you have one. If you only have a regular tape, wrap it around the trunk at the DBH point to get circumference, then divide the circumference by 3.1416 to estimate diameter.
On level ground, measure 4.5 feet above the soil line. On a slope, measure from the uphill side unless your local forestry standard says otherwise. For a leaning tree, keep the tape perpendicular to the trunk’s lean rather than letting it slant with the ground. New York State’s DBH guidance notes that diameter is usually measured 4.5 feet above ground and that special cases such as forks, swelling, and abnormal trunks require consistent handling DBH guidance.
Do not measure at the root flare, at the narrowest point you can find, or at a convenient height near your shoulder if that height is not 4.5 feet. A few inches of diameter error can move the estimate sharply because the calculator squares DBH.
The calculator uses this simple structure:
Estimated stumpage value = DBH in inches x DBH in inches x species multiplier x base rate
The base rate is calibrated so that a 24-inch black walnut returns a rough premium-hardwood screening estimate rather than a generic firewood number. The species multiplier then scales other species groups down from that reference point. Results are rounded to the nearest $10 because a clean dollar amount would imply more accuracy than the model has.
This is not how a forester writes a formal timber appraisal. A formal estimate starts with tree measurements, merchantable height, product class, log grade, and local prices. The U.S. Forest Service describes standing-tree volume estimation in terms of merchantable cubic volume and board-foot volume, including International 1/4-inch board-foot volume volume estimation. The calculator skips that full volume workflow so you can get a first-pass number from a tape measurement and species.
DBH has an outsized effect because trunk cross-sectional area grows with the square of diameter. A 24-inch tree is not merely twice a 12-inch tree in potential volume. It has roughly four times the cross-sectional area before height, taper, defect, and merchantable log length are considered.
That is why small diameter mistakes matter. If you enter 22 inches instead of 24 inches, the diameter-squared term changes from 484 to 576. Before species and base-rate assumptions, that is already about a 19 percent difference. If you enter 30 inches instead of 24 inches, the squared term jumps from 576 to 900.
The calculator uses DBH squared as a practical shortcut for the size effect, not as a true board-foot volume model. Real board-foot estimates also depend on merchantable height, taper, bark thickness, usable log length, and scaling rule.
The species multiplier is a market proxy. It does not mean every black walnut is excellent or every pine is low value. It means that, all else equal, some species groups commonly have higher stumpage potential than others.
Black walnut receives the highest multiplier because high-quality walnut can be sought after for furniture, veneer, and specialty lumber. Oak receives a strong but lower multiplier because oak markets can be good, especially for high-quality white oak and red oak, but price still depends on local demand and log grade. Maple is useful hardwood, but many maple logs do not command the same premium as top walnut or oak. Cedar can be valuable in the right market but is often local and product-specific. Pine is treated as lower in this broad hardwood-oriented calculator, even though pine markets can be strong in regions where pine sawtimber and pulpwood are the dominant products.
Current market reports show why this has to stay flexible. The Missouri Department of Conservation’s timber price reporting project publishes quarterly stumpage trends and states that market value is affected by local considerations such as accessibility, terrain, sale size, and tree size and quality quarterly stumpage trends. A species multiplier cannot see those details.
Suppose you measure an oak at 18 inches DBH. The calculator squares the diameter:
18 x 18 = 324
Oak uses a 0.40 multiplier:
324 x 0.40 = 129.6
After the base rate and rounding, the calculator returns a rough stumpage estimate. The useful part is not the exact rounded number. The useful part is that you can now compare it with a similar-sized maple, a larger pine, or a smaller black walnut using the same model.
If the oak is straight, healthy, accessible, and part of a larger sale, the true value may be higher than a single-tree screening estimate suggests. If it is a yard tree with low limbs, decay, metal risk, or no equipment access, the true timber value may be lower or even zero after removal costs.
Now suppose you measure a black walnut at 24 inches DBH. The squared size term is:
24 x 24 = 576
Black walnut uses the 1.00 multiplier:
576 x 1.00 = 576
With the calculator’s base-rate calibration and rounding, the output lands in a range that signals “worth investigating” rather than “definitely sell.” That is the right interpretation. A 24-inch walnut may be ordinary sawlog material, high-value veneer material, or disappointing material if it has sweep, low branching, rot, metal, storm cracks, or poor access.
This is also where professional review starts to matter. A single premium-looking tree can attract attention, but a timber buyer still has to decide whether the usable logs justify the work and risk. For valuable hardwoods, a consulting forester or qualified timber professional can inspect the tree, identify likely products, and expose the sale to more than one buyer.
If you are unsure whether the tree is maple, hickory, ash, elm, oak, or a mixed hardwood, choose the generic option rather than guessing premium. The generic multiplier intentionally reduces confidence. It is better to start with a conservative estimate and improve it after species identification than to enter black walnut for a tree that only has dark bark from age or wet weather.
For uncertain species, take clear photos of leaves, bark, twigs, buds, fruit, nuts, and the whole tree form. If the tree is leafless, twig and bud features can still help, but identification becomes harder. Local extension offices, state forestry agencies, consulting foresters, and certified arborists can usually narrow the species more reliably than a casual phone photo of bark alone.
Once you know the species, rerun the calculator. The difference between generic and species-specific results shows how much the estimate depended on identification.
Log rules estimate board-foot volume from log dimensions. Doyle, Scribner, and International 1/4-inch rules can return different volumes for the same log because each rule handles taper, saw kerf, slabs, and assumptions differently. The Forest Service notes that log scale volume may be expressed in cubic feet, board feet, cords, tons, linear feet, or number of pieces depending on the product and scaling method log scaling.
The Tree Value Calculator does not ask for small-end diameter inside bark, log length, number of logs, or merchantable height. That keeps it fast, but it also means it cannot distinguish between a 24-inch tree with one short, knotty log and a 24-inch tree with multiple straight, clear logs.
If you already have felled logs with measured small-end diameter and length, use a log scale or board-foot calculator instead of this standing-tree shortcut. If the tree is still standing and potentially valuable, use this calculator only to decide whether a more careful estimate is worth the next step.
Timber is local. A tree’s value depends on nearby mills, active buyers, road access, terrain, harvesting conditions, product demand, fuel costs, tract size, and the number of buyers willing to compete. A strong market in one state does not guarantee a strong market in another.
Penn State Extension’s timber market report is built around quarterly stumpage and mill prices and is intended to describe general market trends timber market report. New York’s Department of Environmental Conservation publishes semiannual stumpage reports with prices split across regions because prices vary within the state stumpage reports. Those examples show why a national calculator can only offer a starting estimate.
If you are preparing for an actual timber sale, find your state forestry agency, extension forestry program, or regional timber price report. Use the calculator’s output as a first filter, then compare it with current local stumpage data.
Diameter and species are only the visible beginning. Log quality often decides whether a tree is premium timber, ordinary sawlog material, pulpwood, firewood, or not commercially useful. Straightness, clear length, knots, sweep, rot, hollows, cracks, metal, insect damage, storm damage, and branching height all matter.
Access can matter just as much. A high-quality tree in a remote ravine, wet site, steep slope, fenced yard, or tight urban lot may be less attractive than a lower-quality tree in an accessible managed stand. Mississippi State University Extension notes that timber quality, tract size, product type, access, distance from the mill, and other factors can raise or lower timber values timber values.
This is why the calculator should not be used as a negotiation anchor by itself. If the estimate is high enough to care about, the next step is better measurement and local market exposure.
Many timber price discussions assume a tract, stand, or sale area, not one yard tree. A buyer can justify time and equipment when there is enough volume to harvest efficiently. One tree has to be unusually valuable, unusually accessible, or part of another job to attract serious timber interest.
Woodlot sales also allow buyers to spread fixed costs across more volume. Marking, cruising, road access, insurance, equipment movement, contracts, and hauling all become more practical when the sale includes multiple merchantable trees. Single-tree situations are often better handled as arborist removal, portable sawmill work, or personal lumber salvage than as a conventional timber sale.
If your tree is on residential property, ask two separate questions: What would it cost to remove safely, and does the wood have any salvage value after removal? Those are not the same question. A removal company may charge for risk and labor even if the log has some marketable wood.
Involve a consulting forester when the tree is part of a woodlot, when multiple trees may be sold, when the calculator suggests meaningful stumpage value, or when you need help marking trees, estimating volume, preparing a sale notice, and comparing bids. Penn State Extension says timber should not be sold unless the seller has an independent appraisal of its stumpage value independent appraisal.
Involve a certified arborist when the tree is in a landscape, near buildings, near utilities, structurally questionable, storm damaged, or important to property value. The arborist’s job is not just to price wood. It is to evaluate health, risk, preservation options, removal complexity, and landscape consequences.
For high-value timber sales, sealed bids can help expose the sale to more buyers. Clemson Extension notes that a consulting forester can help calculate a reasonable minimum bid and that current timber price information can support the process sealed timber bids.
Use the Tree Value Calculator with other measurements instead of treating it as a standalone verdict. If you only know circumference, use the /tools/tree-diameter-calculator/ to convert it to diameter before entering DBH. If you are estimating stand-level stocking rather than a single tree, /tools/dbh-basal-area-calculator/ gives a better forestry lens because basal area describes how much trunk cross-section occupies an acre.
If your question is not timber value, choose a tool that matches the decision. /tools/tree-age-calculator/ helps with rough age estimates. /tools/tree-height-calculator/ helps when height is the missing field observation. /tools/tree-removal-cost-calculator/ is closer to the real issue when the tree is near a structure, dead, leaning, or blocking construction. For planted landscapes, /tools/tree-planting-cost-calculator/ is more relevant than stumpage value because replacement and establishment costs are usually separate from timber value.
The goal is to move from a single rough number toward the right kind of number.
The biggest mistake is choosing a premium species when identification is uncertain. A dark-barked tree is not automatically black walnut. A large oak is not automatically veneer-quality oak. A cedar is not automatically a high-value specialty log.
The second mistake is ignoring defect. The calculator cannot see hollow centers, old fence wire, lightning cracks, low branches, included bark, burls, sweep, rot, or staining. Some defects reduce value slightly. Others can make a log unsafe or uneconomical for a mill.
The third mistake is treating landscape trees like forest trees. Yard trees often have more open-grown branching, more embedded objects, and more removal constraints than woodland trees. They may be excellent shade trees and poor sawlogs at the same time.
The fourth mistake is using timber value to justify removing a healthy, useful tree. If shade, cooling, privacy, erosion control, wildlife habitat, or property character matters, stumpage is only one narrow part of the decision.
Start by deciding what kind of decision you are making. If you are simply curious, the calculator result may be enough. If you are deciding whether to call a forester, treat a higher result as a reason to get a better estimate. If you are deciding whether to remove a residential tree, compare timber value with removal cost and landscape value, not with the tree’s emotional appeal alone.
For a possible timber sale, write down the DBH, species, location, access notes, visible defects, and whether other merchantable trees are nearby. Then contact a consulting forester, state forestry office, or extension forestry program for local guidance. Ask whether the tree is likely to be sawtimber, veneer, pulpwood, firewood, or not marketable.
For a yard tree, call an arborist first if the tree affects safety, structures, or long-term landscape value. If removal is already necessary, then ask whether the trunk can be salvaged for lumber. That order keeps safety and tree health ahead of speculative wood value.
The Tree Value Calculator is best used as a first-pass stumpage screen. DBH and species can tell you whether a tree is likely to be low-value, worth a closer look, or potentially important enough to involve a professional. They cannot tell you final sale value, log grade, removal cost, landscape value, or local buyer demand.
Measure DBH carefully, choose the most honest species category, and read the output as a range signal rather than a promise. If the estimate is small, the tree’s shade, safety, or landscape role may matter more than timber. If the estimate is meaningful, use it to prepare better questions for a consulting forester, arborist, extension office, or timber buyer. A good tree decision is not the one with the biggest theoretical number. It is the one that fits the tree, the site, the market, and the reason you are making the decision.

Estimated stumpage = (DBH in inches) squared x species multiplier x base rate. The base rate is calibrated against USDA Forest Products Lab and Pennsylvania Hardwoods Development Council reports so a 24-inch black walnut at the species multiplier 1.0 returns ~$700 (matching the published sawlog stumpage range of $500 to $1,500 for premium walnut). Species multipliers: black walnut 1.00, oak 0.40, maple 0.35, cedar 0.50, pine 0.10, generic 0.25. Result is rounded to the nearest $10. This is a heuristic for screening, not a replacement for a forester’s appraisal using the Doyle or International log rules.
The long-form review for this page covers Tree Value Calculator. Its bottom source list includes 13 external citations pulled from the long-form guide, then deduplicated with the tool’s frontmatter sources.
Foresters measure the diameter at breast height (DBH, 4.5 feet off the ground) and the merchantable height of the trunk, then use the Doyle Log Scale or the International 1/4-inch Log Rule to estimate the volume in board feet. That volume is multiplied by the local timber market price for the species. A 24-inch DBH black walnut on good soil might yield 200 to 400 board feet worth $3 to $5 per board foot, giving $600 to $2,000 in stumpage value.
Black walnut is consistently the highest-value hardwood in North America because of its dark, figured wood prized for furniture and gunstocks. White oak, red oak, sugar maple, and cherry are also highly valuable. Cedar (aromatic eastern red cedar) commands a premium for fence posts and closet lining. Softwoods like pine, spruce, and poplar have lower per-foot value but grow fast, so they are harvested in larger volumes for pulp and framing lumber.
Stumpage value is what a logger will pay for the standing tree to cut and haul to a mill - typically $100 to $2,000 for a mature hardwood. Landscape value is what a healthy mature tree adds to your property value, often $1,000 to $10,000 for a large shade tree, plus the unpriced benefits of shade, cooling, and air quality. A 30-inch oak might be worth $300 as timber and $8,000 in your yard.
DBH (diameter at breast height) is measured 4.5 feet above the ground on the uphill side of the tree. Use a diameter tape (a tape that converts circumference to diameter directly), or measure the circumference with a regular tape and divide by 3.1416. For trees that fork below 4.5 feet, measure each stem separately and add. For trees on a slope, measure from the uphill side at 4.5 feet vertical height, not 4.5 feet up the slope.
Yes, significantly. Timber prices vary by region: a black walnut in Pennsylvania, Ohio, or Indiana commands premium prices because of nearby veneer and gunstock buyers. The same tree in a region without those mills might be worth 30 to 50 percent less because of transportation costs to the nearest buyer. Urban trees with restricted access (over power lines, near buildings) often cannot be harvested with conventional equipment, which further reduces value.
Almost always keep it for shade unless you have a specific reason to harvest. The stumpage value of a single mature hardwood is rarely more than the landscape, ecological, and aesthetic value it provides over the next 20 to 50 years. Timber harvesting makes sense for: woodlots being actively managed for income, hazard trees that must come down anyway, trees blocking construction, or stands of low-value trees being thinned to improve the remaining crop.
A calculator gives a rough order of magnitude - useful for screening, not for sale negotiations. Real value depends on log quality (straightness, knots, defect), access for the logging equipment, current local timber prices, and the buyer’s needs. For any tree worth more than $500 in stumpage, hire a consulting forester (typically $200 to $500 for a written appraisal) to mark the tree, scale the logs, and run a sealed-bid sale to multiple buyers.
