this thing was good on the smaller trees, a little low on the monsters. i input the sizes from some bigger technical takedowns from the past, and it came up about 50% shy of what the man hours/cost took.
the drivable surface should be more specific, sometimes a structure will get in the way of a chipper or truck, or the path will be too narrow.
something about service (low voltage/communications) wires should be in the overhang section.
These are all valid points and thanks for the input. The idea for the calculator is for a customer to get an idea on pricing, play with the calculator, and then call me and only me. If the measurements are off, or they don't know where I can get my equipment, I explain to them why the calculations they put in will not work. Afterward, I put in the correct calculations, and sometimes we negotiate from that point.
Some of the larger trees we've used this on have not been as profitable for us. Mostly, over 36 inches DBH, sometimes can get as low as $45-$50 per manhour. Our hangup to this point is that we don't have a log grapple, and we spend too many hours cutting and loading wood.
Other large trees though, we do not win the bid, because we are 2X other bids, so the balance is to remain competitive but profitable. In my mind, a tree removal is a commodity that depends mostly on price, while other services that arborists perform take more knowledge and skill, this is where you can differentiate your company and charge what you feel your worth.
Thanks for the comments and this is my .02
