Two corrections: 1. If you look at recent Treasury auctions, 30-year TIPS are actually yielding 1.5%, not 1.3% (https://treasurydirect.gov/auctions/announcements-data-results/ https://treasurydirect.gov/auctions/announcements-data-resul...). 2. In reality, you have a finite lifetime, so you can spend down the principal. Suppose you are 30 years old (about the youngest I could imagine this being possible), and that you plan on living to 100 (most people don't). That's 70 years. If you do the math, and use the 1.5% rate, it works out that you only need $43k, not $77k, to hit that $1k/yr number.
