Realistic range — actual lists tend to fall ~25–40% below the high end after de-dupe & verification.

By industry
Caveats: Based on public Sales Nav + Apollo overlaps across US/EU/UK markets, adjusted for realistic contact-data hit rate. Actual reachable accounts after DNC, blacklist, customer exclusion, and dead-email filtering will land 20–35% lower. The role filter is the biggest lever — if you pick 2 roles, multiply the count accordingly.
After you’ve mapped

The calculator pairs with this: it tells you how many contacts you need to send to hit your MQL target. Run them side-by-side to sanity-check whether your ICP is deep enough for your volume needs.
