Stump Grinding Cost Calculator
Estimate stump grinding from the stump diameter, your price per inch, and the crew’s minimum fee — whichever is higher sets the price.
Calculator
Grinding a 24 in stump at $3.00/in is $72.00, but most crews charge a minimum of $100.00, so budget about $100.00. Measure diameter at ground level; a planning estimate, not a bid.
Once a tree is down, the stump is left behind — and grinding it out is usually a separate charge from the removal. Grinding chews the stump into mulch a few inches below grade so you can seed grass or plant over it. This calculator estimates the job from the diameter you measure, the price per inch in your quote, and the crew’s minimum fee — because on small stumps that minimum, not the per-inch math, is what you actually pay.
Formula
Stump grinding is usually priced by the diameter, with a floor so a small stump still covers the trip:
total = max( diameter (in) × price per inch ($/in), minimum fee ($) )
Measure the diameter at ground level across the widest point, including the flared roots — that is the wood the grinder actually has to chew through.
Worked example
A 24 in stump at $3/in with a $100 minimum:
24 × $3 = $72max($72, $100) = $100
The per-inch math comes to $72, but that is below the $100 minimum, so you would budget about $100. On big stumps the per-inch price wins; on small ones the minimum does.
Measuring the stump and reading the quote
Grinding turns the stump into chips a few inches below grade so you can plant grass or a bed over it. To get a fair estimate and compare quotes cleanly:
- Measure at the ground, not the cut. Include the root flare — a stump that looks 18 in across on top is often 24 in or more at the base.
- Ask how deep. Standard grinding goes a few inches below grade; deeper grinding (to plant a tree or lay pavers) costs more.
- Confirm the minimum. Almost every crew has one — it covers hauling the machine to your site even for a single small stump.
- Chips and roots. Grinding leaves a pile of chips and does not remove surface roots. Ask whether haul-away and backfill with soil are included or extra.
All prices here are the ones you enter, so the estimate never goes stale. It is a planning number, not a bid — get an itemized written quote before you book.
Reference table
How deep the crew grinds changes the price — confirm what your quote assumes:
| Goal | Typical depth | Why |
|---|---|---|
| Surface / lawn | a few inches below grade | Enough to seed grass or lay sod over the spot |
| Bed depth | deeper grind | Planting shrubs or perennials near the old stump |
| Full removal | grind or excavate deep | Building, paving or planting a new tree in the exact spot |
