<prompt> Human: I wasnt able to find this anywhere searching, and this may be very obvious to you guys but...If 4 is the safe withdrawal rate such that your investment has a very high likelyhood of surviving 30 years, then the inverse, is that if you can save 25x the cost of something, that amount of money can fund the purchase of that thing for the next 30 years.For example, lets say that your dream is to have a top of the line new computer that costs 1.5K every two years. To have funding secured youd need 75025 or 18,750 set aside. Or if you want to see a 10 movie every month, youd need to set aside 3,000. Kind of seems like an interesting way of looking at things differently. It might make budgeting more goal oriented which might be helpful.Sorry again if this is completely obvious to you guys, just something I though of.  <response>: Yes, as 1.00 25 0.04.So 0.04 x 25 1.00
