I wish I could give you a flat fee per post, but the truth is that micro influencers all charge different rates. Even the definition of micro influencer can change. With that said, I'm going to assume your definition of a micro influencer has between 10,000 to 100,000 followers on the social media platform of your choice. 

It's important to realize that the price of your post can change drastically based on the social media platform you're choosing. On average, micro influencers charge between $100 to $500 per post. However, there are a couple of things you need to be aware of:

• Instagram is going to be on the pricier side of things for many, especially in the fashion fields. However, it's the industry standard for price ranges. So $100 to $500 is normal. 
• If you want your influencer to put together a video, the price range will double due to the workload it'll take. Influencers can reasonably charge as much as $1250 for a video. 
• TikTok posts are cheaper, between $25 to $150 per post. 
• Twitter is the cheapest option on the list. A micro influencer can charge as little as $20 to $100 for a post. 
• Finally, if you want a Facebook ad from a micro influencer, it can range between $500 to $1250. This is mostly based on how you want to model the ad and if you want to pay to boost it, too.
