In one line

Routing control clusters and readiness checks bill hourly; Region switch plans bill monthly.

What gets missed

A routing control cluster bills every hour from creation to deletion whether or not you ever fail over, and each readiness check bills hourly too. Zonal shift and zonal autoshift cost nothing.
