Stump grinding estimator

Measure each stump across its widest point at ground level, in inches. Multiply by your rate per inch. Add up all the stumps, add anything for hard access, cleanup and travel, and check the total is at least your minimum charge. This tool does those steps with your own numbers.

Use your own costs, not a number from a forum. Work out what an hour of your grinder and crew costs you, how many inches you grind in an hour, and the margin you want. The cost check in this tool shows if your rate per inch covers your costs. The default rate here is only a starting point, change it.

Either way can work, but say which one on the quote. Some owners measure the flare and charge for it. Others measure the trunk and add a percent for big flare. This tool adds a percent you set for medium or large flare, so you can price it the same way every time.

Loading the grinder, driving, unloading and setting up take about the same time for one small stump as for several. Without a minimum, small jobs can lose money. The minimum here applies to the whole job, and you can also set a minimum per stump.

Pick the access level for the job and set the extra percent for tight and hard access. The tool adds that percent to the grinding price and also to the grinding time, because hard access slows the work down.

The tool adds setup time, grinding time (total inches divided by your inches per hour, plus the access percent) and cleanup minutes per stump. That gives hours on site. It also shows crew-hours, which is hours times the number of people.

It depends on your grinder, the wood, how deep you go and how rocky the ground is. There is no single right number. Time a few real jobs, divide the total inches by the grinding hours, and use that.

Some customers want the hole filled or the chips raked out. Others want them hauled away. Set a cleanup or haul-away fee per stump if you charge for it. Put clearly on the quote what is included.

Stumps hide things: rocks, buried roots, old concrete. A range gives you room. You set the spread. One simple way: quote the middle and keep the high end for surprises you explain to the customer first.

Grinding goes below the ground, so buried lines are a real risk. In the US you can call 811 before digging to have public utility lines marked. Check your state rules. Short explanation, not legal advice.
