Curious why people want to have 100% of their Salary at Retirement (sure that sounds great).
But realistically do you even "need" that much.
Example: If you make $80K, I assume you are putting 25% to 401K/Roth and 25% to your Mortgage, and you are spending/Living off about 50%.
Now in retirement, you probably have your house paid off (-25%) and probably not contributing to 401K (-25%), and you are now getting Soc-Sec (+25%).
Heck, you could live the same as now for 25% of your salary(+SS)......
Now, you need to account for inflation, etc.
But, very Generrally thinking....
Heck, you could LIVE at an All Inclusive Resort in Mexico for 6 months a year for about $20K.
The people who want $200K a year during retirement (sounds Fun!), but what are you going to do with it?
House is paid off, not contributing to 401K/etc.
What are you spending $200K on?
Just food for thought...
