Which is better: 1%, 2%, 3%, 4%, 5%, 6% .... ?
The answer ... it depends.
It depends on things like: age, income sources, absolute level of your wealth, health, risk preferences, etc.
George is 80 and is spending 5% with savings of $2M.
Mary is 80 and is spending 3% with savings of $1M.
Jan is 55 and is spending 6% with savings of $1M.
Oh, by the way, Jan has terminal cancer and may only live a few more years. And Mary has a big pension.
So why are so many here talking about their comfortable percentage level and leaving out critical planning details? Probably it's because we don't want to lay it all out here on the internet.
