Ah it does depend on how liquid it needs to be though.
Generally your money invested is better spent than money not. Though its useful to keep a cash reserve.
Personally (and im not sure i would suggest this) i have a credit card i can dump emergency expenses on and pay off when cash has come out of where i store them.
This is probably more true than we want to believe.
We have a different system but similar contribution method in the UK I believe. I have a reasonably decent employer contribution which is right on target of the “half your age” general thought for contributing to retirement.
It’s one thing I think everyone should be doing, its free money from your employer and there are very few reasons not to do so.
The rest of my money that i try to save generally goes into a S&S ISA right now into one fund, and once last years is transferred into another type of fund or EFT.
I have a few shares as well, i look to be on track to make a whopping £80-100 in dividends this year Im happy, its money i didn’t previously have that i can use for my future.
Someone in my work does this… They have no money but are well paid.
