I don't remember the numbers (90% is probably a bit exaggerated) but our savings of going from Atlas to MongoDB Community on EC2 several years ago were big.
In addition to direct costs, Atlas had also expensive limitations. For example we often spin up clone databases from a snapshot which have lower performance and no durability requirements, so a smaller non-replicated server suffices, but Atlas required those to be sized like the replicated high performance production cluster.
