What are everyones rules and goals on how to go about this? Assuming I give 15-20% to my workplace retirement account, has a 6 month emergency fund, what should I do with the 10-20% cash that's leftover monthly. Also assume I have no knowledge on how to invest on my own.
If you're already saving that much, then I would say enjoy the money that is remaining. I'm all for saving, but I also think you should spend and have some fun with your money. I don't know how much you make, but saving 15% should put you in pretty good shape for the future. Live a little!
If you're seriously putting away 15-20% in a 401k and have an emergency fund you're in great shape. You could always fund a Roth IRA as well. You also have a car payment and a mortgage correct? Any student loans or cc debt? I would focus on paying down debt with a vengeance if I was single, childless, and already saving aggresively.
If you're willing to lose some money, put it in the stock market. If not, put it in risk-free cd's that you can redeem at anytime. How much of a down payment have you saved up (in terms of percentage)?
Get a country club membership, try to buy some seats every year to charity galas or local political dinners and start networking. Or invest in professional certifications or grad school.
