Exactly, that's another reason why savings alone won't be a big deal in the long run, inflation will definitely destroy that savings in no time and when you know that you've got 1k USD in savings but then you will be surprised that next month, it's probably valued or worth 998.9 USD, that's how vicious inflation is, that's why when I asked a friend that's been working as a financial advisor, they'll almost always say that it's a good idea to be investing instead of saving alone. Another thing to consider about investing is that you're going to need to balance a life worth living and investing because if you're just investing your money alone and you're forgetting to have fun, the cycle of monotony and despair will be on you and you're not going to reach the age of retirement if you're only focusing on those investments and not having fun, don't put all the money in investments, try to get a vacation at least 2 times a year and get a hobby.
savings accounts swing at like 4% a year. -4% inflation +4% bank interest
however investments swing 8%+.. and here is the thing.. the investment swing is not always positive in investments..
so selling out an investment at a bad time can be a investment loss more then 4% loss.. so you dont want to rely on all your funds being in investments
so putting all your savings into a investment can lose you more money when a surprise happens
the point of savings account is not wealth accumulation.. its a rescue buffer so you dont need to sell investments at a bad time
all you need in savings is initially a months worth of true lean expenses (bills)
EG a stop gap if unemployed between losing job and getting new jobs first pay cheque or social security unemployment payment
if you have a mortgage. you dont need to fund the full monthly mortgage amount into savings. you can just do the 'interest only amount' and then add in the ESSENTIAL bills and bare/cheap/necessary groceries to feed you basic meals for the month
so first save that small emergency rescue pot of money.. and realise that the small $1k may not gain money, but the amount it loses is minimal too when considering everything..
THEN the next month put your other excess income into investments knowing you can THEN invest from now on without worry or panic of needing to rush to cash out investments.. because the savings pot is there instead. to rescue you and give you a month of peace to not need to react in an instant
