Busy Is Not Profitable
Traffic and clicks are activity, not profit. Compare commissions and all attributable campaign costs on the same line.
How To Calculate Affiliate ROI
ROI = (commissions earned minus costs) divided by costs, times 100. A positive result means the campaign made money; a negative result means it cost money.
A Real Example
| Metric | Value |
|---|---|
| Campaign cost (content + promotion) | $500 |
| Impressions | 40,000 |
| Clicks (2% CTR) | 800 |
| Conversions (4% of clicks) | 32 |
| Tracked affiliate revenue | $2,150 |
| Average commission per sale | $67.19 |
| ROI | 330% |
ROI = (Revenue − Cost) ÷ Cost × 100. Here that is ($2,150 − $500) ÷ $500 × 100 = 330%. A campaign only pays if this number is meaningfully positive after every real cost is counted, not just ad spend.
- Add up total campaign cost: content, tools, and any paid promotion.
- Add up total tracked affiliate revenue for that specific campaign.
- Subtract cost from revenue to get net profit.
- Divide net profit by cost, multiply by 100 for ROI percentage.
- Repeat per campaign or per link — never in aggregate across all links at once.
The Metrics That Matter
Track clicks, conversions, conversion rate, commission per conversion, earnings per click, ad spend, cost per acquisition, and net profit per campaign.
Track Per Campaign, Not In Aggregate
Separate offers, traffic sources, and campaigns so profitable work does not hide losing work.
