A lower spending target reduces the size of the portfolio you need. That can make financial independence feel reachable much sooner.
It also demands more confidence that your future lifestyle really will stay lean enough to be comfortable.

Where it gets tricky
Lean plans can have less room for error. A modest increase in housing, healthcare, or travel costs can materially shift the math.
That makes a conservative buffer especially important.
