How Much Does Stump Grinding Cost?
Stump grinding cost is usually $3 to $7 per inch of stump diameter, so a single average stump runs about $150 to $400, with a typical minimum charge near $150. A small 12-inch stump is often just the minimum; a large 40-inch stump can be $200-$400+ on its own.
The price is built from the stump diameter and the number of stumps (additional stumps are cheaper per inch on the same visit), then adjusted for the root system, access, and how you want the chips and hole handled. Grinding is much cheaper than full stump removal. Use the calculator above to localize your estimate, then read on for exactly what drives your quote.

The 6 Factors That Drive Your Quote
1. Stump Diameter
Stump grinding is usually priced per inch of diameter — commonly $3 to $7 per inch — so the width of the stump is the foundation of the estimate. Measure across the widest point at ground level, and include the root flare, since that's what the grinder actually has to chew through. A big 40-inch stump costs far more than a 12-inch one, and small stumps hit a job minimum (often around $150).
2. Number of Stumps
The first stump carries the full setup and mobilization cost, so additional stumps are cheaper per inch when the crew does them on the same visit. Grinding one 24-inch stump might be the minimum charge, but three of them together costs far less than three separate trips. If you have several stumps, always get them done in one visit to spread the setup cost.
3. Root System & Surface Roots
Some trees leave a shallow, extensive root system with roots running along the surface — those cost more because the grinder has to chase and grind the visible roots, not just the stump. Species like maple, poplar, and willow are notorious for surface roots. If you want the roots ground out (not just the stump), that's extra labor and is usually a separate line item from the stump itself.
4. Access & Terrain
Stump grinders are heavy machines that need a clear path to the stump. A stump in an open front yard is easy; one behind a narrow gate, up a slope, in a tight backyard, or boxed in by fences, beds, and hardscape forces a smaller machine or hand-guiding and adds time. Difficult access is a common surcharge (often a flat ~$100) that explains why two same-size stumps can be quoted differently.
5. Cleanup: Chips & Backfill
Grinding produces a surprising volume of wood chips — often more than fills the hole. By default many crews leave the chips mounded on site. Hauling the chips away, chasing and removing surface roots, and backfilling the hole with topsoil and seed are each optional add-ons. Decide up front whether you want the chips gone or kept as mulch, and whether the hole should be filled and leveled.
6. Grinding Depth & Species
How deep the crew grinds matters: a standard grind goes 4-6 inches below grade (enough for grass), while grinding deep enough to replant a tree or pour concrete costs more. Hard, dense species (oak) grind slower than soft ones. Proximity to buildings, fences, and especially underground utilities also affects the job — grinding near lines requires care and an 811 utility locate first.
Stump Grinding vs. Full Stump Removal
These are two different jobs at very different prices — pick based on what you'll do with the spot afterward.
Choose stump grinding when…
- You just want the stump gone and level so you can grow grass or mulch over it.
- You want the cheaper, faster, less invasive option (no big hole, no heavy excavation).
- You're fine leaving the roots to decompose underground over time.
Choose full stump removal when…
- You need to build, pour concrete, or lay a foundation exactly where the stump is.
- You plan to replant a tree in the same spot and need the root ball out.
- You want every root removed — accepting the higher cost and the large hole it leaves.
For the vast majority of homeowners who just want the eyesore gone, grinding is the right call — full removal costs several times more.
How to Vet and Hire a Stump-Grinding Pro
Grinders are powerful machines working near your property and buried lines — vet on safety and clarity:
- Confirm liability insurance — flying debris and machine damage are real risks.
- Ask about utility locating — a good pro insists on an 811 locate before grinding near lines.
- Pin down the grind depth (4-6 in standard vs. deeper for replanting/building).
- Clarify chip cleanup — left on site, hauled away, or used to backfill the hole.
What a complete quote should spell out
- The per-inch or per-stump price and the number of stumps.
- Whether surface roots are included or extra.
- Grind depth, and whether the hole is backfilled and seeded.
- Chip disposal, access surcharges, and confirmation of a utility locate.
Methodology & Sources
This calculator prices the first stump at a per-inch rate based on its diameter, adds each additional stump at a discounted per-inch rate, and applies a job minimum to small jobs. It then adds for an extensive root systemand your selected extras (chip haul-away, root chasing, hole backfill, difficult access), and adjusts the result to your ZIP code's regional price level. In short: (Diameter × Rate, first + discounted extras) + Roots + Add-ons, × Regional Factor.

Frequently Asked Questions
Most stump grinding costs $3 to $7 per inch of stump diameter, so a single average stump runs about $150 to $400, with a typical minimum charge around $150. A small 12-inch stump is often just the minimum, while a large 40-inch stump can be $200-$400+ on its own. Additional stumps done on the same visit are cheaper per inch. Surface-root grinding, chip haul-away, and difficult access add to the total.
The standard is roughly $3-$7 per inch of diameter for a single stump, measured across the widest point at ground level including the root flare — with a job minimum around $150 that applies to smaller stumps. So a 24-inch stump runs about $150-$170, a 30-inch stump around $210, and a 40-inch stump near $280 for the grind alone. Per stump, expect $150-$400 for most residential stumps once cleanup and roots are included. Large-diameter, hardwood, or root-heavy stumps sit at the top of the range. Use the calculator above with your diameter and stump count for a localized number.
Stump grinding uses a machine to chip the stump down to 4-6 inches below ground level, leaving the root system in place underground and a pile of wood chips. It's faster, cheaper, and less invasive. Full stump removal excavates the entire stump and root ball out of the ground — far more expensive and disruptive, leaving a large hole — and is only necessary when you need to build, pour concrete, or replant a tree in the exact same spot. For most homeowners, grinding is the right, cheaper choice.
Measure the diameter across the widest point of the stump at ground level, and include the root flare — the part where the trunk widens out as it meets the ground — because that flare is what the grinder has to remove. Contractors price on that ground-level diameter, not the diameter higher up the trunk. If you have multiple stumps, measuring each (or the largest) helps you get an accurate quote, since per-inch pricing is the industry standard.
Yes. The first stump absorbs the cost of hauling the grinder to your property and setting up, so once the crew is on site, each additional stump is cheaper per inch. Grinding three stumps in one visit costs much less than three separate visits. If you have several stumps to remove, bundle them into a single appointment to get the best per-stump price — and ask whether there's a volume discount.
A standard grind removes the stump to about 4-6 inches below grade — deep enough to cover with soil and grow grass over. If you plan to replant a tree in the same spot, pour a slab, or install something on top, ask for a deeper grind (8-12+ inches), which costs more because it takes longer and produces more material. Deeper isn't always necessary; match the grind depth to what you'll do with the area afterward.
Grinding produces a large pile of wood chips — usually more than enough to fill the hole. By default, many crews rake the chips back into the hole and mound the rest on site, leaving you to spread or dispose of them. For an extra fee they'll haul the chips away and backfill the hole with clean topsoil and grass seed so it's ready to level. Decide up front: keep the chips as free mulch, or pay to have a clean, filled hole.
Usually, yes. The base price grinds the stump itself; chasing and grinding the surface roots that radiate out from it is additional labor. Trees like silver maple, poplar, and willow send out shallow, wide-spreading roots that can lift lawns and hardscape. If those roots bother you, tell the contractor you want them ground too, and expect a per-stump surcharge. If you only need the stump gone and the roots aren't a problem, you can skip it and save.
Yes — calling 811 (Call Before You Dig) to have underground utilities located is strongly recommended before any stump grinding, because roots and grinders can reach buried gas, electric, water, and cable lines. It's free and prevents dangerous, expensive strikes. A reputable stump-grinding company will insist on a utility locate before working near lines, and will keep the grinder clear of marked utilities. Never assume a stump is safe to grind without knowing what's beneath it.
You can rent a stump grinder for roughly $100-$200 a day, which can make sense for one small, accessible stump. But grinders are heavy, kick debris, and are genuinely dangerous to operate without experience, and the rental, transport, and your time often add up to near the cost of hiring a pro for a single stump. For large stumps, multiple stumps, or anything near utilities or structures, hiring an insured professional is usually safer and not much more expensive.
