It’s now up to you to decide how much to invest in your employer’s defined contribution plan (if it even has one), and how to allocate that investment between different investment options.
The SECURE Act requires administrators to disclose to plan participants (i.e, to you) at least annually your “lifetime income stream,” which is how much you could expect to be paid monthly if you were to convert your plan balance to a stream of guaranteed monthly checks.
Since you’re still in the accumulation phase, you probably think of your plan in terms of how much money you’ve set aside, your balance. As you approach retirement, that balance will (hopefully) become a very high number.
