Examples

  • DTC skincare launch: $4,500 micro cost, 320 conversions at $18 vs $12,000 macro, 600 conversions at $20 ⇒ 14.44 % ROI advantage
  • Product drop test: $6,000 micro cost, 400 conversions at $22 vs $15,000 macro, 900 conversions at $24 ⇒ -2.78 % ROI advantage

FAQ

How do I estimate conversion value?

Multiply average order value by profit margin if you want ROI based on profit, or use top-line revenue for gross ROI.

Can I compare two micro campaigns?

Yes, treat one as the 'micro' input set and the other as the 'macro' to see the relative gain.

What if conversions are zero?

The formula allows zero conversions, which yields a negative ROI equal to -100% for that campaign.

Should I adjust for influencer whitelisting or paid amplification?

Yes. Add amplification spend to the relevant campaign cost so the ROI comparison reflects the full investment.
