Influencer campaigns multiply reach through each stage: reach → engagement → clicks → conversions → revenue. This calculator shows full funnel ROI given all conversion rates.

5k campaign × 500k reach × 4% engagement (20k) × 2% CTR (400 clicks) × 3% conversion (12 orders) × 75 AOV = 900 revenue. Loss of 4,100. Most campaigns need much higher reach or deeper funnel optimisation.

Good campaigns typically achieve 2-5x ROI. Best-case B2B with high AOV: 10-20x. Fashion/lifestyle at lower AOV: 1.5-3x. Micro-influencer campaigns often beat celebrity on ROI due to higher engagement.

Run it with sensible defaults

Using campaign cost of 5,000, reach of 500,000, engagement rate of 4%, click-through rate of 2%, the calculation works out to -4,100.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Campaign Cost, Reach, Engagement Rate %, Click-Through Rate %, and Conversion Rate % — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Funnel: reach → engagements → clicks → conversions → revenue. Net = revenue - campaign cost. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

What to do with a low result

A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

£5,000 £ × 500,000 × 4% × 2% × 3% × £75 £ = -$4,100.00.

Inputs

Campaign Cost:5,000 £
Reach:500,000
Engagement Rate %:4
Click-Through Rate %:2
Conversion Rate %:3
Average Order Value:75 £
Expected Result-$4,100.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Frequently Asked Questions

Why funnel matters?
Compounding losses at each stage. 0.5% better at each of 4 stages = 8% better total. Small optimisation at every stage beats big optimisation at one stage.
