How much 100k subreddit make

People are doing so much more work on subreddit, so anyone say how much minimum you can make with 100k subreddit, just need rough amount

No way to know, depends a lot on what you will promote, niche and other things, people can tell their experience, but your will not necessarily be the same.

Well for NSFW ones I have known some people who were making like 5k-10k a month promoting onlyfans/adult CPA offers in 2022-2023 with 100k-200k subs. Though their subreddits were all banned in late 2023.

You could in theory make a lot more/less depending on the creativity you have. For example main things are promoting onlyfans models for which you need either knowing some models directly or their respective agencies.
On the other hand CPA is easier but wayyy less money/conversions and you are risking to get banned easily.
You could also promote your own porn tube if your subreddit is niched.

Lots of things you can do.

There is no way to say. Depending on what you are promoting a few hundred to a few thousand.
