A Chicago hotel and occupancy tax calculator that reveals the gap between the room rate a hotel advertises and the total you actually pay at checkout. Chicago levies one of the steepest combined lodging taxes in the country — about 17.4% — because four separate taxing bodies stack their rates onto the same room charge. This tool adds that combined rate to your nightly rate so you can budget the real cost before you book.
How it works
The combined rate is the sum of every lodging tax that applies to a Chicago hotel room:
Illinois state hotel operators' tax ~6.17%
City of Chicago hotel accommodations ~4.50%
Cook County lodging tax ~1.00%
MPEA / tourism levies ~5.73%
-------------------------------------------
Combined Chicago occupancy tax ~17.40%The calculation is straightforward:
Total = (nightly rate x nights) x (1 + 0.174)
The tax portion is room charge x 0.174, and the grand total adds that on top of the base room charge. The tool computes the room subtotal first, applies the combined percentage, and then breaks the result into the base charge, the tax, and the final amount due.
Example and notes
Book a room at $200/night for 3 nights and the base charge is $600. The 17.4% occupancy tax adds $104.40, for a grand total of $704.40. That tax line alone is more than half a typical extra night.
A few notes: the rate shown is a representative combined figure and can shift slightly as individual authorities adjust their levies, so treat the result as a close estimate. Resort fees, parking, and room-service charges may be taxed separately and are not included here. Stays of 30 days or more are usually exempt from the occupancy tax entirely.
