The FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required. For more on this topic, see Sequence of Returns Risk.

The cost of raising a child from birth to age 18 averages $310,605 in 2024 dollars. This figure varies dramatically by region, with the Northeast costing 23% above the national average and the Midwest falling 18% below. For more on this topic, see Sequence of Returns Risk.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.
