Well, first lets be clear on funds. I think Income funds are poorly named and they mislead people as to their purposed tbh.

You have Accumulator, and Income funds. The difference between those is only dividends, right ? The former reinvests, the latter pays out again.

This means comparing them is confusing because the Acc has pure growth , but the Inc has (growth minus dividends), and dividend yield as well. So the yield is lower because they also have growth. But you are only comparing yield, not yield + (growth) to growth in the Acc funds.

However retirement drawdown is about taking out a fixed percentage of the entire investment out. So income Inc funds imo aren't really suitable anyway imo, and there's no benefits to choosing them over Acc.

I'd stick to Acc funds and take out the 3.2% (or whatever drawdown level is chosen) each year, and not worry about the badly named Inc funds.
