Free tools
Every free creator tool on the internet answers the same way: you type your follower count, it multiplies by a number nobody published, and it tells you what you are worth. These do not do that. They read the record, tell you how many creators the answer came from, and say plainly when there are too few to answer at all.
Engagement rate calculator
Work out the engagement on a post, then see where it sits against creators your size — with the number of creators that answer is drawn from.
What creators charge
The prices actually on file, per kind of post: the low, the middle and the high, where each came from and when it was seen.
If a number here matters to you, the profile it came from is public: open the creator directory and check it, or read how any of it is worked out.
