If you have a station that has limited listeners, then you have unlimited bandwith available. However, if you have unlimited listeners, then you have limited bandwith. You may want to calculate bandwith use. Bandwidth use is determined only by listeners and bit rate. For example, you could be streaming 24/7. But if nobody is listening then you are not using any bandwidth.

Data (bandwidth use) is 1/8 the bit rate per second per listener.

For a 64k stream you would calculate it like this: 64k divided by 8 equals 8k per second for 1 listener.

Take that and figure out how much that is for a month: 8k times 60(seconds) times 60(minutes) times 24(hours) times 30(days). This equals 8*60*60*24*30=20,736,000k. This equals 20,736mb or 20.736gb.

If asking how many listeners a station could have consistently with 1000gb monthly bandwidth at 64k the formula is 1000 divided by 20.736=48.225. Therefore, 1000gb monthly bandwith will support just over 48 listeners average for the entire month at 64k.

For a 128k stream you would calculate it like this: 128k divided by 8 equals 16k per second for 1 listener.

Take that and figure out how much that is for a month: 16k times 60(seconds) times 60(minutes) times 24(hours) times 30(days). This equals 16*60*60*24*30=41,472,000. This equals 41,472mb or 41.472gb.

If asking how many listeners a station could have consistently with 1000gb monthly bandwith at 128k, the formula is 1000 divided by 41.472mb=24.113. Therefore, 1000gb monthly bandwith will support just over 24 listeners average for the entire month at 128k.
