How is Stump Grinding Cost Calculated?
Pricing is straightforward: it is primarily based on the total diameter inches of all stumps. However, a Minimum Service Call Fee ($100-$150) ensures the crew covers their travel and setup costs for small jobs.

Key Factors Influencing Grinding Rates
Root Chasing
Some trees (Maples, Pines) have surface roots extending feet away. Grinding these "chasing the roots" adds labor time and cost.
Cleanup
Leaving the chips is the cheapest option. Hauling them away requires heavy lifting and disposal fees, often adding 30-50% to the bill.
Average Cost by Size
| Stump Diameter | Average Price | Notes |
|---|---|---|
| Small (up to 12") | $100 – $150 | Usually minimum charge applies |
| Medium (18" - 24") | $120 – $180 | ~$3 per inch |
| Large (30" - 40") | $200 – $350 | May involve root chasing |
| Extra Large (50"+) | $400+ | Heavy machine required |
How to Estimate Stump Grinding Cost Manually
Stump grinding is almost exclusively priced by the diameter inch. However, accessibility, surface roots, and cleanup options can double the price of the job.
Step 1: Measure Correctly
Measure the stump at the widest point at ground level, not the cut top. If the ground is humped up by roots, include that hump width.
Step 2: Base Rate Calculation
First Stump: $3.00 - $5.00 per inch.
Additional Stumps: $2.00 - $3.00 per inch.
Step 3: Root Chasing
"Chasing roots" means grinding the visible roots spreading from the stump. This is time-consuming and often adds $50 - $150 to the total.
Step 4: Use the Formula
(Diameter_Inches × $4) + Cleanup_Fee + Minimum_Charge_Adj = Total
Example: For a 30-inch Oak Stump:
(30 inches × $4) + $0 (Leave Chips) = $120 (If above min charge of $100)
Frequently Asked Questions
Does stump grinding kill the tree roots?
Yes, grinding the stump 6-10 inches below grade effectively kills the root system. The remaining roots will decay naturally over a few years.
What happens to the wood chips?
Grinding produces a large pile of mulch (more than you expect). Most quotes assume leaving the chips in a pile. Hauling them away typically costs extra ($4-$6 per inch of stump).
How deep do you grind?
Standard grinding goes 6-8 inches below ground level, which is sufficient for grass or small gardens. If you plan to replant a tree in the same spot, ask for 12+ inches (costs more).
Can I replant in the same spot?
You can, but you must remove the grindings (wood chips) and refill with fresh topsoil because wood chips rob nitrogen from the soil as they decompose, which hurts new plants.
What if the stump is near a fence or foundation?
Accessibility is key. Most grinders need a 36-inch wide gate. Grinding near structures requires extra care and protective shielding, which may increase the price slightly.
Do stump grindings attract termites?
Subterranean termites eat damp, decaying wood. While mulch piles can attract them, the risk is generally low if the pile is not against your house foundation.
Is stump removal the same as grinding?
No. 'Removal' usually means digging out the entire root ball with an excavator, which is much more expensive and damages the lawn. 'Grinding' shaves it down to wood chips.
What if I have utility lines nearby?
You must call 811 before grinding if lines are suspected. If a stump is grown around a gas or water line, it may not be grindable, or requires hand digging (very expensive).
Are there volume discounts?
Yes. If you have 5+ stumps, contractors will often give a bulk rate or 'half-day rate' which is significantly cheaper per stump than doing them individually.
Do I need to fill the hole?
The hole left behind will be filled with wood chips fluff. Over time, it will settle and create a depression. You may want to pay for 'fill and seed' service to level it out.
