The advertised nightly rate on a Salt Lake City hotel is only the start of the bill. Lodging carries a stack of transient room and tourism taxes that push the total up by about 12.42%. This calculator applies that combined rate so you can budget the real cost of a stay.
How it works
The combined occupancy tax is applied to the room rate across all nights:
tax per night = nightly rate × 0.1242
total tax = tax per night × nights
grand total = (nightly rate × nights) + total tax
The 12.42% blends Utah state sales tax, the Salt Lake County transient room tax, the county tourism and restaurant tax, and city assessments. Because these layers stack on lodging specifically, the rate sits well above the ordinary retail sales-tax rate.
Example and tips
A $180 room for three nights has a pre-tax subtotal of $540. At 12.42% the tax is about $67.07, for a grand total near $607. When comparing hotels, always add roughly 12.4% to the headline rate to compare apples to apples, and include any mandatory resort fee in the taxable base — those fees are usually taxed as part of the room charge in Utah.
