Frequently Asked Questions
What withdrawal rate should I use?
The "4% rule" is a common starting point, meaning your portfolio needs ≈ 25× your annual spending.
How do I close a gap?
Save more, retire later, accept lower spending, or take more (appropriate) risk while young.
Does this include Social Security?
No — add any pension/state benefits to your projected income before comparing.
