There is no fixed rate but there are anchors. A common starting point is roughly 100 dollars per 10k followers for a single post, then you adjust up for strong engagement, niche authority, extra deliverables and paid usage rights and down for weak engagement. Micro creators often cost less per post but deliver better engagement, so cost per result beats cost per post. Ask the creator for their rate first, then sanity-check it against their engagement. Use a budget calculator to plan the spread before you commit.

Think cost per result
Micro can cost less and convert more. Compare outcomes, not just post price.
