Is anyone rich here?
You'll want to estimate your anticipated retirement expenses as accurately as possible to come up with how much you'll need to retire. Depending on what you're able to save between now and then, you may need to alter your lifestyle.
Do you have a 401k program at work that matches funds? If so, maximize your allowable contributions, at least to the matched amount. All contributions earn tax free until you withdraw. You may get a bit of a snowball effect from that.
Will you have any other retirement income like Social Security or a pension? If you are counting on Social Security, consider working until age 70. You'll receive a good deal more than if you claim at 65, which is below your full retirement age as defined by Social Security.
One issue you'll be confronted with is you'll be tempted to invest in high return investment vehicles. Advisors often encourage moving towards safer investments as you approach retirement age to minimize risk to preserve savings.
I'd still recommend contacting an advisor like Fidelity. They'll probably have a strategy meant for someone in your situation. They will charge a fee, but my experience has been that they earn all of it.
I'm not rich, but I'm comfortable, and my Son spent several years as a wealth management advisor before moving into a different area in banking.
Good luck!
