Apple on Monday updated its iCloud Web pages, detailing how much it will cost for users to purchase more storage on the service.

[ad#Google Adsense 300×250 in story]According to Apple, three storage plans are available: 10GB will cost $20 per year; 20GB will cost $40 per year; and 50GB will cost $100 per year.

When you sign up for iCloud you get 5GB of storage for free. While that doesn’t seem like much, consider that your purchased music, apps, and books, as well as your Photo Stream, don’t count against your free storage.

iCloud was introduced at WWDC and is expected to launch this fall.
