For those in the industry, how do you abbreviate the words "million" and "billion" in your official finance research and communications?

MM
M
mm
m
mil
B
bil

I don't know why this is important to me, but it is. For million, I used to be an "M" guy, then changed to "mm" for a while, and now use "m" pretty much exclusively. This convention is now consistent with my lowercase "b" for billion and, as an added bonus, my lowercase "k" for thousand.

While this works for me and I generally feel good about it / don't lose sleep over it, if there were an Emily Post of finance etiquette, which abbreviations would be the most appropriate to use in your grammatical opinion?

Which I get is like 1,000 1,000, but what do you use for billion? And if you use MM for million, shouldn't you use M for thousand for the sake of logical consistency? How confusing would that be?

That's why I've said to hell with the Roman convention and gone instead to m, b and k. Not to mention, for anyone who's ever written an equity research report with a limited number of characters on the cover note page, using MM multiple times in a paragraph that is heavily referencing financial dollar amounts can eat up a lot of character space compared to using just m.

1,000 - 1k
1,000,000 - 1mm
1,000,000,000 - 1bn

I can get behind that. The lowercase k I feel is standard in Western parlance. The MM I feel is a relic from the Roman system which by Roman standards could also mean 2,000 so I prefer your mm to it. And then there's the M with the bar on top that could also mean billion. It's a bloody mess.

I think k, m or mm, and b or bn is the way to go.

Wether you go k, m, b or k, mm, bn....people are generally going to get the gist. No need to complicate further.

M = thousand; although this is not used often. More likely to see ('000) as an annotation.

MM = millions

B = billions

I'm not in finance, but deal with financial reports, so it depends on the audience. Most of what described above is financial, but if you're going to operations teams:

1,000 = k
1,000,000 = m/M
1,000,000,000 = b/B (most often described as 1,000 m/M though)
