Most financial planners estimate you need $1.2-$1.5 million saved to retire comfortably in the Chicago metropolitan area, assuming you want to replace about 80% of your pre-retirement income. However, the real number depends on your lifestyle, healthcare needs, and whether you plan to stay in the Northern Suburbs or relocate.
The standard rule of thumb, 25x your annual expenses, gives a starting point, but it significantly understates what Northern Suburbs families need. A household spending $150,000/year (not unusual in Wilmette, Winnetka, or Northbrook when you include property taxes of $15,000-$30,000/year) needs a portfolio of approximately $3.75 million to sustain that spending, plus Social Security. National retirement calculators systematically underestimate the cost of staying in this area.
Property taxes are the largest single variable that separates a Chicago-area retirement budget from a national average. Cook County and Lake County have some of the highest property tax rates in the country. A $900,000 home in Northbrook may carry a $16,000-$22,000 annual tax bill. A $1.5 million home in Winnetka may exceed $30,000. Unlike most retirement expenses, property taxes typically don't decrease until you downsize, and they increase with inflation. This is a $1,300-$2,500/month expense that must be built into your income plan.
Healthcare costs are the second major variable. Before Medicare at 65, a couple retiring at 60 must fund 5 years of private health insurance, easily $30,000-$60,000 per year in the current market. After Medicare enrollment, costs drop but don't disappear: Part B premiums, Medigap coverage, Part D, and dental/vision can still total $18,000-$30,000/year per couple. Illinois's favorable retirement income tax treatment (no state tax on Social Security, IRA, or pension distributions) partially offsets these costs.
Social Security timing dramatically affects how much portfolio savings you need. A couple both delaying to age 70 might collectively receive $60,000-$100,000+ per year in Social Security, covering a substantial portion of a Northern Suburbs retirement budget. Each additional year of delay reduces the portfolio withdrawal rate required and extends the longevity of your savings. We model multiple Social Security scenarios alongside the portfolio to find the combination that requires the least total savings.
Key facts
- Rule of 25: multiply your annual spending by 25 to estimate the portfolio needed at a 4% withdrawal rate, a $150,000/year household needs approximately $3.75M
- Cook County property taxes: 1.5-2.5% of assessed value annually, $15,000-$30,000/year for a $1M+ home
- Pre-Medicare healthcare (ages 60-64): budget $30,000-$60,000/year for a couple on the open market
- Post-Medicare healthcare: $18,000-$30,000/year per couple for premiums, supplements, and out-of-pocket costs
- Illinois retirement tax advantage: Social Security, IRA, and pension distributions are exempt from the 4.95% state income tax
- Social Security at 70: a couple with two Social Security earners delaying to 70 can collect $60,000-$100,000+/year, reducing the portfolio withdrawal needed by up to 40%
Should I stay in Illinois or move to Florida or Arizona for retirement?
The financial case for staying is stronger than it appears from a tax standpoint. Illinois already exempts Social Security, IRA, and pension income from state tax, so moving to Florida or Texas saves you zero on those income sources. The real savings would come from lower property taxes and potentially lower housing costs. On a $900,000 home carrying a $18,000 Cook County property tax bill, moving to a state with 0.5% property tax rates saves $13,500/year. Whether that's worth leaving your community, healthcare providers, and family proximity is a personal calculation, not just a financial one.
How does the 4% rule apply to a Chicago retirement?
The 4% rule says you can withdraw 4% of your starting portfolio value each year (adjusted for inflation) with a high probability of not running out of money over 30 years. In the Northern Suburbs, this rule needs to be calibrated for local costs. At 4%, a $3 million portfolio generates $120,000/year. If your property taxes, healthcare, and living expenses total $160,000/year, you need either a larger portfolio, significant Social Security income, or a slightly higher withdrawal rate, which increases your depletion risk. We stress-test your specific numbers, not a national average.
