How long does 2GB last on the iPhone 5?

Yesterday I got the iPhone 5 with a package for 2GB a month. Whenever I am at home or a place that has wifi I will use internet with it, but when I'm on the road I'll use the 4g internet. I will not be using apps such as pandora or netflix during this time, YouTube at the most for videos. I'll just be surfing the web, like Facebook and regular sites like that. How long do you think this will last for me?

As long as you don't watch videos or download music. It last a whole month. I have a 2 gb plan but I have wifi so I only you about 500 mb from GPS and google: Facebook. If you watch a lot of videos I would recommend a 4 gb plan. But since at home you have wifi you should be good.
