There are many variables. I'll share mine. Rusty pilot returning after 25yrs. Only 265hrs TT, Commercial and instrument license, obviously not current. Current BFR and new Tail wheel endorsement with only 15hr tail wheel time. So, I think I must qualify for the higher end of the insurance premium range. Lucky me. I pay $2000 a year. They assured me it would go down as I obtained more tail wheel time. Im currently at 130hr and and on track to have 200hrs tail wheel time by March renewal. Hope its better and certainly don't want to see and increase.
