How it calculates
- Extra revenue recovered per month = current monthly revenue (spend × ROAS) × expected conversion recovery rate.
- Net gain = extra revenue recovered − monthly hosting/maintenance cost.
- Breakeven recovery % needed = hosting cost ÷ current monthly revenue × 100 — typically well under the 5–20% recovery range server-side tagging usually recaptures from ad-blockers and Safari/Firefox tracking prevention (ITP), which is why it is usually worth it once implemented properly.
