In one line

Standard bills per state transition. Express swaps that for a per-start charge plus memory-seconds.

What gets missed

Standard counts every transition, retries included. Distributed Map bills one per iteration, an Inline Map none — so not every loop costs. Express bills duration times memory instead.

Find it on your bill

Filter Cost Explorer or your Cost and Usage Report by these usage types. A usage type with no region prefix means us-east-1.

Bills the same way

These services turn exactly the same meters, so what you learn here transfers.
