Question: how much money do you need to live comfortably without working?
Answer: Add another 25% on top of that for a buffer – you'll need $62,500 a year. With taxes considered, that takes you up to almost exactly $70,000 a year. With the TIPS at 4.25%, you just divide that annual amount by the TIPS rate – giving you a target number of $1.65 million for a very secure long-term situation.
