Sarah is 43, just became a library assistant after being a stay-at-home mom for 19 years, and has zero retirement savings after her ex-husband kept all the retirement accounts in the divorce. She has $86,000 in combined income right now — but the alimony dwindles in 5 to 9 years. George and Jade crunch the numbers: 15% of $86K is $1,075/month, and investing that from now until 65 puts her over $1 million.
