These days, depending on where you live, the cheapest of the cheapest burials, no service, no funeral, no embalming, no obituary, just cremation and burial can cost $8,000 to $10,000.
Simply transporting the body to the funeral home/crematory, placing it in a freezer until it's ready for cremation, the wooden box where they cremate it, placing the ashes in a urn, the urn, the death certificate, etc. are all very expensive and add up quickly.
