CPM Influencer Marketing: How to calculate profitable campaigns

Influencer Marketing is one of the most effective growth levers in e-commerce - but 90% of all brands pay significantly too much for their influencer campaigns (1). The reason: They don’t understand how to properly evaluate and negotiate influencer prices. The result is five-figure marketing budgets burned without the collaborations actually being profitable.

The solution lies in a simple but powerful concept: the CPM, i.e. the price per thousand contacts. With this key figure you can objectively compare different influencers, calculate the profitability of your influencer campaigns in advance and conduct well-founded negotiations. Using this approach, Ad Specialist has already managed over 10,000 influencer marketing campaigns with an advertising budget of more than 50 million euros for e-commerce brands such as Upway, Livom, MyMuesli and Duschbrocken (1).

Before we get into the details, I would like to recommend our detailed video tutorial on the topic. In “How to Negotiate Influencer Prices Like a Pro” I show you step by step how to work with CPM calculations and conduct successful negotiations with influencers. The video is based on experiences from over 10,000 controlled influencer campaigns and gives you practical insights into our negotiation strategies.

TKP stands for contact price per thousand and describes how much it costs your company to reach 1,000 people with an advertising message. This key figure originally comes from classic media advertising and has established itself as a central key performance indicator in performance marketing. The term is also known in English-speaking countries as CPM (Cost per Mille), where “Mille” is the Latin word for thousand. You can find the general basics of the key figure – formula, gross/net reach and use across all advertising channels – in our basic article on Thousand Contact Price.

In Influencer Marketing you calculate the CPM by dividing the cost of a placement by the reach achieved and multiplying it by 1,000. An example: If you pay 2,000 euros for an Instagram post and it reaches 50,000 people, your CPM is 40 euros (2,000 euros ÷ 50,000 × 1,000 = 40 euros per 1,000 contacts).

The big advantage: you make influencer prices comparable. A content creator with 50,000 views for 2,500 euros has the same CPM as an influencer with 100,000 views for 5,000 euros - namely 50 euros CPM (1). This way you can objectively evaluate which cooperation offers the better price-performance ratio.

A good CPM depends heavily on the platform, the target group and the format. In general, the lower the CPM, the more cost-effectively you can reach your community. In organic Influencer Marketing, the costs per 1,000 contacts are significantly higher than with classic advertising, but offer a more authentic form of approach and higher engagement rates (2).

The benchmarks from thousands of campaigns show:

Instagram Stories: A good CPM is around 30 euros (1). Anything above that should be critically questioned.

YouTube Integrations: CPMs between 30 and 50 euros are standard here (1). For very wide-reaching videos with over a million views you can expect to pay around 30 euros, for normal videos more like 50 euros.

Instagram Reels and Posts: Prices per post vary greatly by influencer category. While nano-influencers (1,000-10,000 followers) often charge between 50-250 euros per post, mega-influencers with several million followers can charge five to six-figure amounts (3).

The influencer costs per 1,000 contacts vary greatly depending on the social media platform, content format and reach.

Instagram: Stories, Posts and Reels

The usual market price for Instagram stories is around 30 euros (1). What is important is that the number of followers is completely irrelevant to the calculation. What matters is the actual story reach that an influencer achieves. An Instagram profile with 100,000 followers may only generate 3,000 story views - that's a huge difference to an account with the same number of followers but 15,000 story views (1).

Actual prices depend heavily on the influencer category (3):

• Nano-Influencer (1,000-10,000 followers): 10-100 euros per post
• Micro-influencer (10,000-100,000 followers): 100-1,000 euros per post
• Macro influencer (100,000-1 million followers): 1,000-10,000 euros per post
• Mega-Influencer (over 1 million followers): 10,000+ euros per post

YouTube integrations

With YouTube you pay between 30 and 50 euros CPM (1) for a typical integration of around 90 seconds of advertising, depending on the reach. For videos with a very high reach (over a million views) you can expect a CPM of around 30 euros. For normal videos with an average range, the CPM is closer to 50 euros (1).

TikTok influencers and their prices

TikTok has become one of the most important platforms in influencer marketing. The prices per post are often lower here than on Instagram, as the organic reach is significantly higher thanks to the algorithm. TikTok influencers can often reach double or triple their number of followers, which lowers the CPM accordingly.

Cross-industry benchmarks usually place the effective CPM on TikTok in the low double-digit range - depending on the source, around $2 to $15 per 1,000 views (6). Due to the high algorithmic reach, the CPM is often below the Instagram level, while the conversion rate often lags behind other channels.

Twitch Streams: The special case

Twitch works completely differently than the other platforms in the marketing mix. Here you can expect a CPM of around 1,500 euros – a number that seems extremely high at first glance (1). The crucial difference: This CPM refers exclusively to the concurrent live viewers, i.e. the viewers who are watching live at the same time, not to the overall reach of the stream (1).

The CPM alone says nothing about the success and profitability of your influencer campaign. What matters is how many people actually become new customers from the reach achieved and what ROI is achieved.

YouTube achieves an average conversion rate of 0.25% (1). This means that out of 10,000 people who see your placement, around 25 will become new customers.

Instagram Stories have a lower conversion rate of around 0.15% (1). So with 10,000 story views you will only gain around 15 new customers. The average engagement rate on Instagram is around 0.36-0.56%, with nano and micro influencers often achieving significantly higher rates (4, 5).

Twitch achieves an impressive 5% conversion rate (1). With 1,000 simultaneous live viewers, you gain 50 new customers - that's twenty times more than on Instagram and YouTube.

With the key figures CPM and conversion rate you can calculate exactly whether an influencer placement is profitable. The formula:

Conversion rate = (new customers ÷ reach) × 100 (1)

Practical calculation example YouTube

Imagine you are negotiating with a YouTube content creator who is expected to reach 20,000 views. You conservatively assume a conversion rate of 0.2% (1).

Your invoice:

• 20,000 views × 0.2% = 40 new customers
• Your maximum CAC is 20 euros
• 40 new customers × 20 euros = 800 euros (1)

To calculate the CPM: 800 euros ÷ 20 = 40 euros CPM (1)

If the creator charges more than 40 euros CPM, the placement becomes unprofitable.

Influencer prices are influenced by various factors. According to the Influencer Marketing Benchmark Report 2025, the industry is valued at $32.55 billion, representing growth of 35.6% over 2024 (2).

Nano-Influencers (1,000-10,000 followers) often have a very engaged community and achieve engagement rates of up to 5-10% (4). The cost per post is between 10 and 100 euros (3).

Micro-influencers (10,000-100,000 followers) offer the best value for money in influencer marketing. The prices are between 100 and 1,000 euros per contribution (3).

Macro-influencers (100,000-1 million followers) and mega-influencers (over 1 million followers) are relevant for brand awareness campaigns. The costs can range from 1,000 euros to six-figure amounts per post (3).

Other important factors are the engagement rate, the niche and target group, the content creation effort, the exclusivity and the usage rights.

Our detailed guide to Influencer Marketing Costs shows how these factors specifically affect your budget by platform and type of cooperation.

Before you enter into a price negotiation, you must request the correct data.

Instagram: Show you the story reach of the last 30 days (1). In addition, you should get the link clicks. The rule of thumb is: you shouldn't book anything with a click rate of less than 5% (1).

YouTube: View video views from the last 30 days (1). What is important is the average per video, not individual outliers. The average watch time also gives you information about the content quality.

Twitch: Use tools like Twitch Tracker to see average concurrent live viewers and peak viewers over the last 30 days (1).

The most successful strategy is maximum transparency (1). Tell the influencer openly: “We are interested in a long-term collaboration, but as a company we have certain profitability goals that we need to achieve” (1).

Then you show him the bill. You explain: "Based on our experience, with 20,000 views we can expect around 40 new customers. With our CAC target of 20 euros, we can invest a maximum of 800 euros. Given your reach, this corresponds to a CPM of 40 euros" (1).

Why does this work? Because the influencer also has an interest in the campaign working (1). If he sees that you work based on data, he will take you seriously.

One point that stands above all: Every influencer should test your products for a reasonable period of time and really stand behind them before you work together (1). No cooperation without authentic experience reports.

In addition to the classic CPM model, there is also the option of working with influencers on an affiliate basis. Here you don't pay for the reach, but for the sales actually generated. The advantage: You only pay if you are successful, your ROI can be calculated from the start. A mixed form of basic salary (CPM) plus success commission (affiliate) can be a good middle ground.

The negotiation has been won, the influencer has agreed - but now comes the contractual protection (1).

Compensation clauses for underperformance

Imagine you negotiate 20,000 views at a CPM of 40 euros and pay 800 euros. But the video only reaches 10,000 views. Suddenly you pay 80 euros CPM – double (1). That's exactly why you need compensation clauses. Ad Specialist always writes in contracts: “If the achieved reach deviates by X% from the agreed reach, there will be an additional Instagram story or a new YouTube integration as compensation” (1).

Staggered CPMs: Your risk drops drastically

Staggered CPM models are even better (1). You agree on different prices depending on the reach achieved:

• For 1,000,000 views: 30 euros CPM = 30,000 euros total costs
• For 500,000 views: 40 euros CPM = 20,000 euros total costs
• For 250,000 views: 50 euros CPM = 12,500 euros total costs (1)

Your overall costs and risk decrease dramatically when the creator delivers less reach (1).

The CPM in influencer marketing is your most powerful tool for controlling campaigns profitably. The per-thousand contact price makes influencer prices comparable - regardless of whether Instagram, YouTube, TikTok or Twitch. The benchmarks are 30 euros for Instagram Stories, 30-50 euros for YouTube and 1,500 euros for Twitch (1). Conversion rates vary massively by platform: YouTube is 0.25%, Instagram is 0.15% and Twitch is 5% (1).

Nano-influencers and micro-influencers often offer the best value for money. Demand the right insights – the number of followers is irrelevant, story reach and average video views count. Negotiate transparently with data and protect yourself contractually through compensation clauses and staggered CPMs.
