Influencer marketing ROI calculator

Model what a creator budget returns before you commit it — views, clicks, conversions, cost per acquisition and ROAS for YouTube integrations and Instagram Stories across six markets. Every output is a range, and every benchmark behind it is graded for how solid the underlying data actually is.

7 inputs

Indexed off US creator pricing. Note this runs opposite to paid media: US auction CPMs are the highest in the world, but European creator CPMs are not. A German or British creator charges a minimum fee against a smaller audience, which raises the price per thousand views.

Views, not followers. You buy impressions, and follower count predicts them badly — a 200k-follower channel averaging 12k views costs the same as a 12k-view creator and delivers the same.

Questions

How to read this forecast

Why a range instead of one number?

Because the underlying data does not support one number. Published creator CPMs differ between sources by a factor of three to five. A tool that hides that spread is not more accurate, it is just more confident.

Why only two formats?

YouTube 45–60s integrations and Instagram Stories are what we plan, buy and measure most often, so they are the two we can model honestly. There is no credible public CPM for YouTube Shorts or Twitch sponsorships, so we leave them out rather than invent them.

Why average views and not followers?

You are buying impressions. Follower count is a poor predictor of them — view-to-follower ratios vary by an order of magnitude between channels. Pricing on average views is also how the maths works: CPM is cost per thousand views.

What does the forecast leave out?

Agency fee, production, usage rights, organic spillover, brand lift and repeat purchase. It models a first-order media outcome. Everything above the line is upside you should not plan on.

How accurate is it really?

The conversion side rests on solid data. The cost side does not. Where a number is weak we say so with a grade, and the forecast checks itself against published market rates — if it drifts far outside them, it tells you which input is probably wrong.

What makes your forecast better?

We run the campaign and measure it. Every placement ships with a tracking link and a creator promo code, so the forecast we send you is calibrated on delivered results rather than public averages.

Methodology

Where every number comes from

Most calculators in this category present modelled assumptions as measurements. This one grades each constant instead, because the honest finding is that the cost side of influencer marketing rests on much thinner evidence than the conversion side.

Grade ADisclosed sample, period and method.
Grade BPublished aggregator citing named sources.

C2026Social Cloud estimate — no public data exists. The last cross-country creator CPM study was published in 2017. Deliberately the inverse of paid-media indices: creator deals carry minimum fees, and in Europe that fee lands on a smaller audience, which raises CPM. Adjust to your own rate cards.

AFeb 24–Feb 25Liftoff / Singular — 2.4bn installs, $11.9bn spend, globally averaged. Scaled by the market index above, because a global average is not a fair yardstick for a single country. Used only to flag an implausible forecast, never as an input.
Scenario band on CTR and conversion×0.7 / ×1.0 / ×1.4CModelling choice, not a measured distribution. Downside and upside stack every assumption in one direction, so both are corner cases.

On app ROAS. Revenue per install defaults to a payback-window figure, not day one. Casual games recover roughly 47% of install cost by D30 — a ROAS near 1.0 at your payback horizon is a healthy campaign, not a failing one.

On e-commerce ROAS. This is first-order ROAS only. It ignores repeat purchase, and for most DTC brands that is where creator campaigns actually pay back — a figure near 1.0 on the first order can still be a strong programme once returning customers are counted. Enter your contribution margin per order rather than gross AOV if you want the stricter view.

Creator media is not paid media. A creator CPI running somewhat above your paid-UA benchmark is normal, not a failure: you are buying attention, trust and content you can reuse, not just an impression. The forecast only speaks up when the gap is wide enough to suggest a wrong input.
