Understanding the Instagram sponsored post rate — concept and principle
Creators and brands both need a starting price for a sponsored Instagram post. Follower count alone is a weak guide, because two accounts of the same size can have very different levels of real interaction. This calculator prices a feed post from the engagements it is expected to earn, scales it for a Reel, and shows the common follower-based rule of thumb next to it so you can compare the two. It works with any currency.
How it is calculated
- Expected engagements = followers × engagement rate ÷ 100
- Feed post price = expected engagements × price per engagement
- Reel price = feed post price × Reel multiplier
- Rule of thumb = followers ÷ 1,000 × 10
Engagement rate is usually likes, comments, saves and shares per post divided by followers. The rule of thumb is a US-dollar benchmark: US$10 per 1,000 followers.
The principle
A brand pays for attention and action, and engagements are the visible sign of both. Pricing by engagement rewards accounts whose audience actually responds, and penalises accounts with inflated or inactive followers. The price per engagement plays the same role as a cost per click in paid advertising: it lets you compare a sponsored post with other channels. The Reel multiplier reflects that short video usually takes more work to produce and can reach people beyond the current followers.
Worked example
- Inputs: 40,000 followers, engagement rate 3%, $0.25 per engagement, Reel multiplier 1.5.
- Expected engagements = 40,000 × 0.03 = 1,200.
- Feed post price = 1,200 × 0.25 = $300.00.
- Reel price = 300 × 1.5 = $450.00.
- Rule of thumb = 40,000 ÷ 1,000 × 10 = $400.00.
How to read the result
When the engagement price is below the rule of thumb, as here, the audience is engaging less than the benchmark assumes, or your price per engagement is low. When it is above, a highly engaged niche audience may justify the premium. Most negotiations end somewhere between the two and then add separate fees for usage rights (the brand reusing your content in ads), exclusivity, extra Stories or link placements, and tight deadlines.
Common mistakes
- Calculating engagement rate from one viral post instead of an average of recent posts.
- Granting paid-ad usage rights without charging for them.
- Forgetting the platform's and your country's disclosure rules for paid partnerships.
Frequently asked questions
What is a good engagement rate on Instagram?
It depends on account size and niche; smaller accounts often have higher rates. Compare with your own history and with similar accounts.
Should Stories be priced the same as a feed post?
Stories disappear after 24 hours unless saved, so they are commonly priced lower or sold as a bundle with a post.
Does the rule of thumb change with the currency?
No. It is always shown in US dollars; with another currency selected the calculator shows the US$ amount marked "convert", so convert it at today's rate and adjust it for your market.
