Calculating your true EPC in 4 steps (the one most affiliates get wrong)

Calculating your true EPC in 4 steps (the one most affiliates get wrong)

EPC (earnings per click) is the cleanest cross-offer comparison — but blended EPC hides where you actually make money.

▸ Step 1 — Use confirmed revenue, not pending. Pending FTDs get rejected; count validated conversions only.
— Step 2 — Segment EPC by GEO and device, never just one blended number. A $0.40 blended EPC might be $0.90 on Tier-1 desktop and $0.05 on Tier-3 mobile dragging it down.
— Step 3 — Include the RevShare tail. On hybrid deals, day-one EPC understates true EPC; add projected RevShare per click from your LTV model.
— Step 4 — Recompute over a rolling 30-day click window so a single big depositor doesn't spike one day's number.

Blended EPC is a vanity metric. Segmented, validated, tail-inclusive EPC is what you actually optimize against.

Benchmark of the day: across ~25 segmented offers, the top device/GEO segment's EPC ran 4-9x the bottom segment's within the same offer — invisible in the blended figure.
