Reveal Ad Spend

Reveal Ad Spend adds a missing column to the Meta Ad Library: how many people in the EU each ad reached. Meta publishes this figure under the Digital Services Act, and the free Chrome extension pulls it onto every ad card so you can sort a whole results page by reach instead of guessing.

From there it estimates spend with a transparent formula (reach / 1,000 x CPM x frequency) using the CPM and frequency you enter, and builds a printable per-ad report with the creative, copy and the EU audience by age, gender and country when Meta shares it. A free CSV of CPM estimates by EU country and niche from Pantheon helps you pick realistic values.

No usage limits and no payment; a free account is needed. Works only for ads delivered in the EU, and the spend shown is an estimate.
