Depends on where you are at any given time. If you are in the middle of the ocean, you will be lucky if you get one or 2. If you are in a major city, you could get 15+.
In the US, FM broadcast stations are spaced at 200KHz intervals on the dial, starting with 87.9MHz and ending with 107.9MHz, giving 101 allocations. Other countries use different intervals, which varies according to your location ... information that you, like so many others, chose not to give us in your profile.

I live in a suburb of Canada's largest city, with numerous Canadian cities around me and many cities in United States not far away. On a sensitive "high-fidelity" FM tuner or good quality car radio I get about 100 FM stations, so my dial is full.
Huh? I'm in Mississauga which is a suburb of Toronto. I can see Canada's largest city's downtown from my home's windows. I don't know how many FM transmitters are in Toronto's transmission tower that I can see. 20? 30?
