A cab ride from JFK Airport to Manhattan runs around $55-$60, including the flat fare, tolls, and tip, but it can be more for the metered ride to JFK. Taxi fares just went up 26% last May, but cabbies are agitating for another increase, with greatly increased gas costs eating at their daily take. I usually only take taxis on weekends, but I'm finding myself spending at least $50 a week. Combine that with my monthly $76 subway pass and it's still quite a bargain, to my mind, anyway. At least you can get a cab in NYC, unlike when I lived in SF, where post-clubbing cab hailing becomes a blood sport.
