Google Plugin and Cost?

Hi all,
I’m building a project management application and I’ve started to look at the google plugin bubble offers. I’ve found a few tutorials regarding install, setup etc, however I can’t seem to wrap my head around the potential costs on google side? Can anyone give me a rough idea as to what google is going to charge me for - let’s say about - 10 users accessing their gmail, and calendar functions via our application? Does that sound like .10 cents a day type of thing? Or, 100 bucks a month type thing?

Free. Sounds free to me. Using those apis is free!

Knowledge source:
I just set that up for my calendar plugin (to access google calendars and share them even when the user is offline)

That said, I could be way off.

This is good, thanks @jared.gibb. It does lead to me ask… How are the apps we build via bubble categorized by google? Can we assume they are a “Consumer App?” Or could they be "Enterprise SaaS or Hybrid Service? Are these categories based on bubble’s relationship to google or our own individual APP built within bubble’s platform? Perhaps someone from @bubble.io can speak to this?
