A San Francisco hotel quote is never the real price. Every taxable stay carries the city’s 14% Transient Occupancy Tax, plus Tourism Improvement District and Moscone Expansion District assessments that hotels list on the folio. This calculator stacks all of them on your room subtotal so you can see the true cost before you book.
How it works
Each charge is a percentage of the room subtotal, then summed:
subtotal = nightly rate × nights
TOT = subtotal × 14%
TID + Moscone = subtotal × (assessment %)
total = subtotal + TOT + assessments
effective % = (total − subtotal) / subtotal × 100
The 14% Transient Occupancy Tax is fixed by the city. The district assessments vary by hotel and tier but typically add another 1% to 3%, so the all-in effective rate lands between roughly 15% and 17%. The tax applies only to stays under 30 consecutive days; longer continuous stays are exempt as permanent occupancy.
Example and tips
A $280 room for 3 nights is an $840 subtotal. The 14% TOT is $117.60, and a 2.25% combined district assessment adds $18.90, for an all-in total of about $976.50 — an effective rate of roughly 16.25%. If your hotel charges a mandatory resort fee, add it to the nightly rate before calculating, because that fee is itself subject to the occupancy tax.
