Influencer Marketing ROI: How to Calculate and Improve Your Return

Influencer marketing ROI is calculated as (value generated minus total cost) divided by total cost, multiplied by 100. The hard part is not the formula but deciding what to count: all costs (fees, production, products, agency, paid media) and all value (tracked sales, the value of content you can reuse, and brand effects). According to CreatorIQ’s latest State of Creator Marketing report, 48 percent of brands report a return of at least three times their investment – but Linqia found that 79 percent of marketers still struggle to measure ROI at all.

This guide explains how to calculate the return on an influencer campaign step by step, which tracking methods work, and how to improve the result. It is a practical complement to our earlier article on measuring celebrity campaigns beyond views.

How will influencer marketing ROI be measured in 2027?

Measurement is one of the fastest-changing parts of influencer marketing. The latest reports point to four developments to plan for in 2027:

• More brands reach a higher return. In CreatorIQ’s latest State of Creator Marketing report, 48 percent of brands report a return of 3x or more, and the share breaking even or losing money fell from 21 to 13 percent.

• No single method wins. In the same report, no measurement methodology is preferred by more than 19 percent of brands – sales attribution leads, followed by marketing mix modelling and platform dashboards. Plan to combine methods for each goal.

• Data integration becomes the main challenge. CreatorIQ reports that integrating creator data and workflows across systems has overtaken measurement as brands’ top roadblock, and 58 percent of paid media leaders struggle to measure creator-driven paid performance separately (Creator-Powered Funnel).

• Creator commerce links content to sales. 48 percent of brands have integrated creator commerce into their strategy, and 68 percent of the brands that make it a core part report a return of 3x or more (CreatorIQ, State of Creator Marketing).

For 2027 this means: decide your measurement model before the campaign, connect creator data with sales and paid media data, and report short-term sales and long-term brand effects side by side.

What is the formula for influencer marketing ROI?

The basic formula is the same as for any investment:

• ROI (%) = (Value generated – Total cost) ÷ Total cost × 100

An illustrative example: if a campaign costs 200,000 kronor in total and generates 500,000 kronor in tracked value, the ROI is (500,000 – 200,000) ÷ 200,000 × 100 = 150 percent. Put differently, every krona invested returned 2.5 kronor. Many reports express this as a multiple – “2.5x” – instead of a percentage.

Which costs should be included?

A common mistake is to count only the talent fee. A fair ROI calculation includes every cost the campaign required:

• Fees to influencers or talent, including usage rights.

• Production: filming, editing, locations, travel and props.

• Products sent out and shipping.

• Agency fees for strategy, talent management and project management.

• Paid media used to amplify the content.

• Discounts given through promo codes.

• Internal time, if you want the full picture.

Which values should be included?

Value is where calculations differ most. We recommend separating it into three layers and reporting them side by side rather than adding everything into one number.

1. Directly tracked sales

Revenue that can be tied to the campaign through promo codes, affiliate links, UTM-tagged links or platform shop features. In Influencer Marketing Hub’s latest Benchmark Report, promo or discount codes were the most common tracking method (45.9 percent), followed by affiliate links (26 percent) and native shop features (25 percent). Direct sales are the most conservative measure – they almost always underestimate the true effect, because many people see a post and buy later or in a physical store.

2. Content value

Creator content is increasingly reused in ads, on websites and in other channels. CreatorIQ’s Creator-Powered Funnel report found that creator content makes up 44 percent of brands’ paid media creative on average, and 77 percent of paid media marketers say it outperforms traditional branded ads. If a campaign gives you content you would otherwise have had to produce, the saved production cost is real value – provided you have secured the usage rights.

3. Brand and media effects

Reach, engagement, brand awareness, consideration and earned media. Some use earned media value (EMV), where impressions are valued at what equivalent paid reach would have cost. EMV is useful for comparing campaigns, but it is an estimate rather than revenue, so it should not be mixed with sales in the same ROI figure. For brand effects, a brand lift study or a before-and-after survey gives a more reliable picture.

How do you track sales from influencer campaigns?

• Unique promo codes per talent – simple and easy to understand, but they leak to coupon sites and miss buyers who forget the code.

• Affiliate or UTM-tagged links – precise for online sales, but they miss people who buy later via search or in a store.

• Platform shop features – sales directly in the app where available.

• Attribution windows – influencer-driven purchases often happen days or weeks after exposure, so a short window underestimates the effect.

• Geo or time-based tests – compare sales in regions or periods with and without the campaign.

• Marketing mix modelling – for larger brands with enough data, a statistical model can estimate the channel’s contribution.

The most robust approach combines several methods. Attribution is the weak point for many: Linqia’s latest report found that 48 percent of marketers cite attribution as their biggest measurement gap.

What ROI can you expect from influencer marketing?

There is no universal benchmark, and you should be wary of single “average ROI” figures without a source. What the more robust reports show is this:

• 48 percent of brands report a return of three times or more, up from 37 percent the year before (CreatorIQ, State of Creator Marketing).

• More than 80 percent of paid media marketers report at least a 2x return from creator marketing programmes (CreatorIQ, Creator-Powered Funnel).

• 40 percent of US buyers name overall ROI as their primary KPI for creator campaigns (IAB, 2025).

• 65.9 percent of marketers expect influencer activity to pay back within one month (Influencer Marketing Hub, Benchmark Report).

That last point deserves a comment. Expecting payback within a month works for performance campaigns with a clear offer. For brand building – where a well-known personality builds recognition over time – much of the value appears later and is not captured by short-term sales tracking.

How can you improve influencer marketing ROI?

• Set one primary goal per campaign – awareness, consideration or sales – and choose KPIs to match.

• Choose talent based on audience fit and credibility, not follower count alone.

• Negotiate usage rights from the start so the content can work in paid media.

• Amplify the best-performing organic content with paid media.

• Prefer long-term partnerships: Sprout Social reports that 71 percent of influencers offer discounts for multi-post or long-term deals.

• Let the talent’s own tone carry the message – content that feels genuine performs better.

• Decide on tracking before launch, not after.

What does this look like in practice?

When Collabri ran the Swedish launch of Fazer Domino, organic creator content on TikTok and Instagram was combined with a paid strategy from the start. The campaign reached more than 3.5 million views and 14,000 interactions. Planning organic and paid together is one of the most effective ways to get more out of every krona spent on content.

Key takeaways

• ROI = (value – cost) ÷ cost × 100 – but include all costs, not just the fee.

• Report direct sales, content value and brand effects separately.

• Combine several tracking methods; promo codes alone underestimate the effect.

• Nearly half of brands report a return of three times or more, according to CreatorIQ.

• Set goals and tracking before launch – that is what makes ROI provable.

Frequently asked questions

What is a good ROI for influencer marketing?

It depends on goals and industry. As a reference, 48 percent of brands in CreatorIQ’s latest State of Creator Marketing report say they get at least three times their investment back. Compare with your other channels rather than with a global average.

Is earned media value the same as ROI?

No. EMV estimates what the reach would have cost to buy, which is useful for comparisons, but it is not revenue. Keep it separate from sales-based ROI.

How long after a campaign should you measure results?

Track during the campaign and for several weeks afterwards. Purchases inspired by influencers often happen with a delay, and brand effects take even longer to show.

Can you measure ROI for brand-building campaigns?

Yes, but with other metrics: brand lift, search volume for the brand, consideration and long-term sales trends. Combine them with reach and engagement to get the full picture.
