You'll only get approximately 5 kilobytes (0.005 megabytes) added to your monthly usage (guesstimate).
BlackBerry doesn't automatically download attachments - You have to manually download. Even so, the size is usually downconverted when viewing. When viewing, it does not automatically add that many megabytes - downloading usually only takes a few kilobytes to a few hundred kilobytes, depending on what you are doing... Viewing the contents of a zip file, or viewing one attachment of many, or viewing an image (downconverted in size), or a PDF (stripped of its images), etc.
