I'm still a ways off from my own RMD, at 70.5, as I'm only 48. I might start tapping those funds a little early though, once the time gets closer, if it might be tax advantageous to do so.
However, I have two inherited IRAs...the first from my grandmother, who passed away in 2015, and the second from my Dad, who passed away in 2017. So far, the withdrawals have been small. I think for Grandmom's, it was around $126 in 2016, $88 in 2017, and $117 in 2018. It's in a somewhat aggressive/volatile fund, and only started off with around $4800, so that's why it's fluctuated so much. I've just been depositing these into my checking account and they get spent, invested, or whatever with the rest of that money.
The second IRA, from my Dad, was a bit more sizeable, around $66K. The first RMD was around $1800 this year. I didn't need it, so I put it in a money market account that I'm currently using, to save up for the down payment on a house. I think the APR on it is about 1.66% annually. I figured I'd keep this conservative, since I might need the money in a few years.
