Definitely the BEST margin calc

Wow, THATS the quality! Was looking for a margin calc for a time. Even tried some other margin calcs here. And thats the only one that fits the highest standarts of design and usability. The icon is funny a bit though:)
Anyway, if you need to know your margin - that app will count it quickly and easily.
