What does it cost to remove old existing insulation?

It can cost $2500 to $5000 or more to have all your insulation removed and replaced, so make sure you're having the right insulation removed and that you're replacing it with more efficient insulation.
It may be better to leave the existing insulation in place and it will cost less to just “top up”, putting insulation on top of the existing. You will need less insulation to top-up compared with fully insulating after removal of existing insulation.
