Even if your $20K is a correct national average figure for family insurance costs, you can't do that and get meaningful results; insurance costs vary widely between states and localities (e.g., of ACA exchange plans, the statewide as average second lowest cost silver plan costs for states using the federal marketplace range from $459 in ND to $1,185 in WY—and the range of local rates, and/or including the states that don't use the federal exchanges, is even wider.) So you'd need to map local income against local costs to get anything meaningful.
