Key takeaway: A single person renting a median $2,079 Chicago one-bedroom needs about $57,400 a year before taxes to cover typical monthly costs and save 10%, or about $42,400 sharing a two-bedroom, once federal, Illinois and payroll taxes are counted.
The 30% rule says to keep rent at 30% of your income. It’s a useful starting point, but it ignores what the rest of your life costs and what taxes take. This calculator works the other way: add up what you’ll actually spend in Chicago, then work back to the salary that covers it after taxes and savings. Rent figures come from our neighborhood profiles; change any number to match your plans.

How the math works
Our calculation: monthly spending times 12 is what you need to take home after taxes and savings. The calculator then finds the salary where salary, minus federal income tax, minus Social Security and Medicare, minus Illinois income tax, minus savings, equals that amount.
| Tax | 2026 rule used |
|---|---|
| Federal income tax | Salary minus the $16,100 standard deduction, taxed at 10% up to $12,400, 12% to $50,400, 22% to $105,700, 24% to $201,775, 32% to $256,225, 35% to $640,600 and 37% above |
| Social Security | 6.2% of wages up to $184,500 |
| Medicare | 1.45% of all wages, plus 0.9% above $200,000 |
| Illinois income tax | 4.95% of salary minus the $2,925 personal exemption |
| Chicago sales tax | 10.5% on shopping and fun spending |
| Chicago phone taxes | 7% telecommunications tax plus a $5 monthly 911 charge per line |

- Groceries: $367 is the average of the USDA moderate-cost food plan for an adult man and woman. See our grocery guide.

What this calculator leaves out
It assumes a single filer paid by W-2 with no 401(k) or other pre-tax deductions and no tax credits. Pre-tax retirement savings lower your income tax, so if you save through a 401(k), your real tax bill will be a little lower than shown. Illinois phases out the personal exemption above $250,000 of income, which this calculator does not apply. For move-in costs, see Chicago move-in costs.
