Presumably you mean early retirement since target retirement income only matters when calculating how much to have saved. That is a nice goal and I’d like to see more couples attempt it. However, retiring with the ability to withdraw only $20k is so little. Even small emergencies would force a big percentage drawdown. There would be zero ability to respond to family events with additional travel or assistance. If the retirees move to a cheap area to make budget, there’s possibly even more travel. Better to work a few more years, for most. Percentage of income is a crude tool, but the realistic flat amount to live can easily be 50% of retirees’ working income. Personal taste and family situation add to that.
