Stump grinding cost looks simple on paper: most tree services quote a few dollars per inch of stump diameter. In practice, two things decide your bill more than the per-inch rate does. The first is the minimum charge, which swallows most small stumps. The second is how the stump gets measured, because the widest point at ground level is often much bigger than the trunk you remember.
This guide walks through the math the way a grinder operator does it, then covers what pushes a quote up, how multi-stump and bundle pricing work, what renting a grinder costs once you add it all up, and what to do with the pile of grindings afterward.
Quick Answer: Most residential stumps cost about $100 to $400 to grind. Many companies price at roughly $2 to $5 per inch of diameter, but a minimum charge of about $100 to $150 usually applies, so small stumps cost the minimum no matter what the per-inch math says. Additional stumps on the same visit are typically much cheaper than the first. Expect extra for hardwoods, big surface roots, tight access, deeper grinding, and hauling away the grindings. Renting a grinder runs about $150 to $300 a day.
How Much Does Stump Grinding Cost?
For a typical residential stump, plan on $100 to $400. That range comes from current published pricing guides and contractor rate sheets, not a national survey, and local markets vary widely. A rural operator with a small machine may charge less; an insured company in a high-cost metro area may charge noticeably more. One Eastern North Carolina contractor that publishes its prices lists $250 to $400 for stumps under 12 inches, well above the national figures you’ll see repeated online, and explains that the national average blends in a lot of tiny stumps.
The number that matters most for small jobs is the minimum charge. Most companies charge about $100 to $150 just to unload the machine, because the trip, setup, and cleanup cost the same whether the stump is 6 inches or 16.
How Do You Calculate Stump Grinding Cost?
The standard formula is simple:
Stump diameter in inches × per inch rate = base price, or the minimum charge, whichever is higher. Then add any extras: hardwood, surface roots, access, depth, or hauling.
The Per Inch Rate vs. the Minimum Charge
Here’s how the national $2 to $5 per-inch range plays out against a typical $100 to $150 minimum:
| Stump Diameter | Per-Inch Math at $2 to $5 | What Usually Happens |
|---|---|---|
| 10 inches | $20 to $50 | Minimum charge applies |
| 20 inches | $40 to $100 | Minimum charge applies |
| 30 inches | $60 to $150 | Minimum, or just above it |
| 45 inches | $90 to $225 | Per-inch price, plus extras |
That’s why so many homeowners are surprised. The per-inch rate makes a 20-inch stump sound like $40 to $100, but few companies grind a single stump for that. Real quotes for common 12- to 24-inch stumps tend to land around $150 to $300 (see the size table below), because the per-inch figure is only the base. Operators add the trip minimum, hardwood time, surface roots, access, and depth, and many local companies charge more per inch than the national guides suggest. The per-inch rate matters most on big stumps and on additional stumps during the same visit.
Rates vary by company. Some charge more per inch for larger stumps, and some quote a flat price per stump instead. Ask which method the quote uses.
How to Measure a Stump for a Quote
Most stump grinding quotes come from a photo and a measurement, so measure it right.
- Measure across the widest part of the cut surface at ground level. Iowa State University Extension notes that arborists charge by stump size measured at its widest point.
- Include the root flare. Trees widen where the trunk meets the soil. A contractor that publishes its pricing points out that a tree that was 18 inches across at chest height can leave a stump 26 inches wide at the cut, and hardwoods like oak, maple, and sweetgum flare more than pine.
- Note surface roots. If roots run along the surface for several feet and you want them ground too, say so up front, since that’s extra grinding time.
- Photograph the access. A wide shot showing gates, fences, slopes, and how close the stump is to the house helps the operator pick the right machine.
Measuring from the trunk you remember, instead of the stump you have, is the most common reason a quote goes up when the crew arrives.
Stump Grinding Cost by Size
These are planning ranges drawn from current pricing guides and contractor rate sheets. Treat them as a budget starting point, not a price list.
| Stump Diameter | Typical Price Range | Notes |
|---|---|---|
| Under 12 inches | About $75 to $150 | Usually the minimum charge |
| 12 to 24 inches | About $150 to $300 | Most common residential stump |
| 24 to 36 inches | About $300 to $500 | Hardwoods and root flare push toward the top |
| Over 36 inches | Custom quote | Often priced by the hour or as a job |
Older stumps that have started to rot are usually faster to grind. Stumps that have sat for years can also collect soil and rocks around the base, which slows the machine and wears down the carbide teeth.
Multiple Stumps and Bundling With Tree Removal
The first stump carries the trip and setup cost. Every additional stump on the same visit is cheaper, because the machine is already there. National pricing guides commonly put additional stumps around $40 to $75 each, depending on size.
Two ways to use that:
- Grind every stump at once. If you have an old stump from years ago and a new one, do both on the same visit.
- Grind the stump the same day the tree comes down. Bundled grinding skips a second trip charge entirely. Tree removal usually doesn’t include the stump unless you ask, so confirm it’s on the quote.
On LawnGuru, tree work averages $425, with most jobs between $300 and $1,200, and stump grinding is one of the cost factors providers price in. Get tree work quotes through LawnGuru, add stump grinding to the request, and compare up to five local quotes before you book. If the tree is still standing, our tree removal cost guide covers that side of the bill.
What Raises the Price: Hardwood, Roots, Access, and Depth
Hardwood vs. softwood. Dense hardwood species like oak, hickory, maple, and sweetgum take longer to grind than softwood like pine, and they wear grinder teeth faster. Some companies add a hardwood surcharge; others just quote hardwoods at the top of each size range.
Surface roots. Species with aggressive surface roots can double the area the operator needs to grind. Decide before the crew arrives whether you want visible roots ground or just the stump.
Access. Stumps behind narrow gates, on slopes, tight against a fence or foundation, or far from where a trailer can park need a smaller machine or more time. Open yards with good access are the cheapest jobs.
Depth. Illinois Extension notes that grinders can work anywhere from flush with the soil to more than a foot down, and the deeper you go, the more it costs. Iowa State says professional grinding typically reaches 8 to 12 inches. Many contractors quote 6 to 8 inches below grade as standard, which is enough for grass, and charge extra for deeper grinding before a patio, foundation, or new tree.
Rocks and buried debris. Old stumps with rocks, wire, or fencing grown into them slow the job and can damage teeth.
Hourly vs. Per-Stump Pricing
Most residential stumps are priced per stump or per inch. Some companies charge per hour instead, often for large stumps, lots of roots, or land-clearing jobs with many stumps. Published guides put hourly stump grinding around $125 to $200 an hour.
Hourly pricing makes sense when you have a lot of stumps, or when roots are a big part of the job. For one or two typical stumps, a per-stump quote gives you a fixed number and puts the risk of a slow, rocky stump on the contractor.
Hauling, Fill, and What to Do With the Grindings
Grinding turns the stump into a mound of grindings: wood chips and sawdust mixed with soil, sitting in and around a shallow hole. What happens to that pile is a separate line item.
Iowa State notes that most arborists won’t remove the shavings or fill the hole unless you ask, and both usually cost extra. Published guides commonly put hauling at about $2 to $4 per inch of diameter or a $50 to $200 flat fee.
Whether to pay for hauling depends on what goes there next:
- Planting grass in the same spot: have the grindings hauled or dig them out yourself, then fill with topsoil. Iowa State and Illinois Extension both say wood mixed into the soil changes its structure and ties up nitrogen, which is why grass struggles over old stumps. Our seeding cost guide can help you budget for replanting the spot.
- Using it as mulch: the chips are useful on top of the soil in beds and around shrubs. Washington State University Extension rates arborist wood chips among the best mulches for trees and shrubs, recommends keeping them 4 to 6 inches deep for weed control, and warns against working wood into the soil as an amendment or piling it against trunks and foundations.
- Composting: Iowa State notes the shavings can go in a compost pile or to a municipal composting site.
If you’d rather buy clean mulch than reuse grindings, our mulch cost guide covers bulk and bagged prices.
Will the Stump Resprout After Grinding?
The ground-out portion won’t regrow, but some species can resprout from live roots left in the soil. It’s most common when a healthy tree was cut and ground quickly.
Both Iowa State and Illinois Extension recommend treating a fresh cut while the wood is still alive. Iowa State says to apply a herbicide with glyphosate, triclopyr, or imazapyr to the living cambium ring just under the bark, cut any sprouts that appear, and reapply until they stop. It specifically advises against products with picloram, which leaches and stays active in the soil, and notes that pouring herbicide into a stump long after removal doesn’t speed decay and can damage nearby plants. Some contractors include a regrind guarantee for sprouts, so ask.
Is It Cheaper to Grind or Remove a Stump?
Grinding is almost always cheaper. It takes the stump down below the surface and leaves the deeper roots to decay. Full removal means digging or pulling out the stump and major roots, usually with an excavator, which costs several times more and tears up more of the yard.
Pay for removal only when something is going in that exact spot, like a foundation, patio, or new tree. For everything else, grinding is the better buy. The stump removal cost guide compares both methods side by side.
Can You Grind a Stump Yourself? Rental Cost and Risks
Yes, with a rental machine. A stump grinder typically rents for about $150 to $300 a day, plus fuel and a trailer if you don’t have one. For one or two small, accessible softwood stumps, renting can beat a pro’s minimum charge.
The math changes fast:
- Rental units are smaller. A stump that takes a professional machine half an hour can take hours with a walk-behind rental, especially hardwood.
- Large stumps may not be realistic. Big oak or maple stumps can eat the whole day.
- The machine throws debris. Wear eye, ear, and face protection, and keep people and pets well away.
- Call 811 first. 811 is the free national call-before-you-dig service. Contact it a few business days before grinding so buried utility lines get marked. The 811 program notes some utilities are buried only inches deep.
If you have several stumps, hardwoods, stumps near structures, or anything over about 18 inches, hiring a pro usually costs about the same once you count rental, transport, and your time.
How to Save on Stump Grinding
- Bundle with tree removal. Same-day grinding skips a second trip charge.
- Do every stump in one visit. The minimum applies once, and additional stumps are cheaper.
- Measure and photograph accurately. Avoid surprise increases on site.
- Clear the area. Move toys, rocks, edging, and debris from around the stump.
- Keep the grindings. Use them as bed mulch and skip the hauling fee if you’re not planting grass there.
- Ask for standard depth unless you need more. Deeper grinding costs more.
- Get two or three quotes. Per-inch rates and minimums vary a lot between companies.
Frequently Asked Questions
How much to take down a 30ft tree?
It depends on the species, trunk size, what the tree could fall on, and whether cleanup and stump grinding are included, so most companies quote it on site. On LawnGuru, tree work averages $425, with most jobs between $300 and $1,200. Ask for stump grinding on the same quote to avoid a second trip charge.
How long does it take to grind a stump?
A small stump can take 15 to 30 minutes with a professional machine. Large hardwood stumps with surface roots can take an hour or more. Rental machines are slower.
How deep does stump grinding go?
Many contractors grind 6 to 8 inches below grade as standard, which is enough for grass. Iowa State says professional grinding typically goes 8 to 12 inches. Deeper grinding for construction or a new tree costs extra.
How much does it cost to grind 10 stumps?
Less per stump than grinding them one at a time. The minimum applies once, and additional stumps are usually priced lower. For many stumps, some companies offer an hourly or day rate with an operator, so ask for both quotes.
Does tree removal include stump grinding?
Usually not. Stump grinding is a separate line item, so confirm it’s included if you want it.
Is it cheaper to grind a pine stump than an oak stump?
Usually. Pine is softer and has less root flare, so it grinds faster. Oak and other hardwoods take longer and wear the cutting teeth more, so they land at the top of each size range.
Can a stump grinder work right next to a fence or house?
Often yes, with a smaller machine and more care. Tight access usually adds time to the quote.
Do I need to call 811 before stump grinding?
Yes. Grinding cuts into the soil, and some utility lines run just inches below the surface. Contact 811 a few business days ahead, or confirm your contractor does.
What happens to the hole after stump grinding?
The grindings usually go back in the hole as a mound unless you pay for hauling. For grass, remove the wood and fill with topsoil, since wood in the soil ties up nitrogen.
