Depends a lot on the age one would need 50k/yr. At age 65, probably around 1.6 would do it with conservative withdrawal rates and an allowance for inflation. If your receipent in question is disabled at age 35, probably 2 million dollars wouldn't do it. Also, these averages have some built-in probablity for running out of money--maybe 5-10% chance. The .gov disability doesn't, short of national bankruptcy and we throw the disabled under the huge bus.

Agreed, anyone should enter retirement basically debt free, esp mortgages. And the 70% replacement goal is likely high and finance advisors like it because it makes people save more. My calcs make me think 50-60% should be enough.
