If You Have $640,000 Saved at 61 and a Daughter Starting Med School, Here Is the Monthly Income You Can Actually Count On

A 61-year-old single filer plans to retire at 62 with $640,000 split between a traditional 401(k) and a Roth IRA. Social Security at 62 is estimated at $1,890 per month, reflecting a 30% reduction from the full retirement age amount. A $1,200 monthly commitment for four years of medical school is expected to total about $57,600. A 4% withdrawal rate from the $640,000 nest egg yields about $25,600 per year, or roughly $2,133 per month. Adding early Social Security produces about $4,023 per month before taxes. With income above the single-filer threshold, 85% of Social Security becomes taxable, increasing AGI and reducing take-home income after federal income tax.

"You want to retire at 62. The real question is not what your portfolio says on paper, but what actually reaches your checking account after Social Security taxation, federal income tax, and the support you have promised your daughter."

"You have quietly committed to sending her $1,200 a month for living expenses. The support is meant to help bridge the years of medical school, with the understanding that a physician's future earning power should eventually allow the daughter to fully support herself and manage her student debt independently."
