The three case study household savings amounts used in the video are $1 million, $3 million, and $5 million.
The speaker's bottom line is that Roth conversions are not a guaranteed strategy as they are often sold; instead, they are a gamble that depends on factors like lifespan, future tax brackets, and heirs' situations. He emphasizes that most of the time, this bet will fail.
This video argues that Roth conversions are often presented with overly optimistic projections that assume unrealistically long lifespans. The speaker, Eric Amselog, a certified financial planner, uses case studies with $1 million, $3 million, and $5 million portfolios to demonstrate how shortening the assumed retirement period significantly alters and diminishes the projected benefits of Roth conversions, highlighting them as a gamble rather than a sure strategy.
