Paying 1.86% at Ameriprise and thinking about simplifying. Is that fee still reasonable?

I’m 56 and retiring in October. I have about $750k invested. I also have a military pension (34 years Army) and my home is paid off.

Here’s the rough breakdown:

About $420k in an inherited IRA (this includes a $148k annuity)
About $240k in a Roth IRA
About $80k in a taxable brokerage account

I’m currently with Ameriprise and paying around 1.86% AUM on the managed portion.

The portfolio is made up of around 30 to 40 individual stocks, multiple ETFs, some active management, and the annuity inside the inherited IRA.

I trust my advisors and have been with them for over 14 years. They’ve never been pushy and I feel comfortable with them.

As I move into retirement, I’m thinking I would prefer something much simpler, maybe something like:

70% total U.S. market ETF (VTI or similar)
20% international index
10% bonds

If the portfolio were simplified into broad index ETFs like that, would 1.86% still be considered reasonable?

If I asked them to reduce the fee closer to 1%, is that realistic in today’s advisory world? That’s really my biggest concern. I don’t ask them for much, and when I run the numbers, the long‑term impact of a 1.86% fee could easily exceed $150k to $200k over the next decade or so

I’m trying to decide whether I should negotiate the fee and stay, move to a flat-fee advisor, or just manage a simple index portfolio myself.

1. Move to a flat‑fee advisor
2. Self-manage with index ETFs

Would appreciate objective thoughts.
