The starting price for a helicopter is around $340,000.00 which is more than some peoples homes cost and some helicopters can cost in the millions of dollars for more fancier helicopters.
If you only plan to fly a helicopter once in awhile then it's best to rent a helicopter instead for $250.00 to $350.00 per hour.
If you own a private helicopter you'll need to factor in fuel cost and maintenance cost and storage costs which can really add up.
