Using an online service, such as LegalZoom, to create a POA will cost $35–$45 depending on how complex the document needs to be.
The most expensive option is using an attorney, who may charge $300 or more to draft a POA. If you’re looking for the least expensive option, you can try to do it yourself. The only cost for this method may be getting the document notarized, but you may find this process difficult if you’re unfamiliar with these types of legal documents
