I've been on auto-pay with my ROTH-IRA for years. I take the max annual contribution, divide it by 12, and pay every month. It's called Dollar Cost Averaging.
I turned it off this Fall because (a) I refused to get a day job with (b) made me broke which (c) made me unable to afford my ROTH-IRA auto-payments. Tonight I turned them back on starting in February.
Feels good to be back.
