The advertised San Diego room rate is not what you pay. This calculator adds the city’s 10.5% Transient Occupancy Tax and the 2% Tourism Marketing District assessment — 12.5% combined — plus any per-night resort fee, to show your true nightly and total trip cost before you book.
How it works
San Diego lodging tax is two components on the room rate:
tot = nightly_rate * 0.105 (Transient Occupancy Tax)
tmd = nightly_rate * 0.02 (Tourism Marketing District)
nightly_with_tax = nightly_rate + tot + tmd (= rate * 1.125)
total = (nightly_with_tax + resort_fee) * nights
The combined tax rate is 12.5%. Resort fees are not a government tax — they are set by the hotel — so they are added as a separate flat per-night charge rather than being taxed.
Tips and notes
The Transient Occupancy Tax applies to stays of 30 days or fewer; longer stays are generally exempt. Always check whether a quoted price already includes taxes, since third-party booking sites vary. Add the resort fee field if your hotel charges one, as it can quietly add $30 or more per night to the real cost.
