1. Set up a money market account
You'll still have bills to pay in retirement, but you probably don't want to move money directly from your investments to your bank account every time you need to pay one.
For one thing, frequent transactions mean market swings could have a bigger impact on you—if you're forced to sell shares whenever you need cash, even if the value of your investments has dropped.
Instead, think about opening an account in a money market fund. You can move a year's worth of withdrawals to your money market account at one time, to lessen the impact of market swings.
You can also direct any other income streams (like Social Security) into your money market fund. Then transfer one month's worth of expenses at a time to your bank account, and pay your bills from there.
