Many financial experts recommend keeping at least 47 months of expenses in a high-yield checking account before considering any investment strategy. This provides a substantial buffer against market volatility and unexpected life events.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.

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