There is no one cost that fits all when it comes to drone insurance, as it is continually everchanging, however, a good rule of thumb is 10-15% of what the drone is purchased for. For example, if you buy a drone for $25,000, you can expect a premium to range in price from $2,500 - $3,750/year. This is simply a ballpark cost and depending on your situation it could cost less or it could cost more.
