i didn't know that ......where you do your through?
I got family that handle my portfolio.....but good ones are Vanguard, Fidelity. Open one up, discuss fees/expense ratios (both companies are known for some of the lowest fees), basically put it in nice growth mutual funds and/or ETFs.
So while thieving megabanks wanna give you at best 1-2% on your money, you could be getting at least the market average of 8-12% annually on your savings. typically you don't wanna touch retirement accounts, but w/a Roth if you ever need it (hopefully not if you got that nice emergency fund), you know you can tap into your contributions w/no penalty. Again just leave the earnings and let it compound like any other investment.
If you maxing your 401k see if they offer a Roth 401k option, which is after tax contributions. Leave whatever you've earned there (most 401ks are typically pre-tax), then switch to Roth 401k. Get that tax-free growth breh. Because if your employer provides a match, 99% of the time the match is a pre-tax contribution. So you have balance, getting tax breaks now w/pretax contributions (thus lowering your taxable income buy when you withdraw at retirement age you will pay taxes then), and the Roth which will grow tax free (which means when you withdraw that money it's already been taxed so you're gucci).
I tell everyone if you can start a Roth IRA do it. It's literally the best savings account imo for entry-level retirement other than an employer-matching 401k (because they're giving you free money basically).
