Portland advertises hotel rooms at the pre-tax rate, but the transient lodging tax adds a meaningful chunk to every night. This calculator applies Portland’s combined 15.3% lodging tax so you can see the real per-night and full-stay total before you commit.
How it works
The tax is a flat percentage of the taxable room rate, applied per night and multiplied across the stay:
nightly tax = room rate × 15.3%
nightly total = room rate + nightly tax
stay subtotal = room rate × nights
stay tax = stay subtotal × 15.3%
stay total = stay subtotal + stay tax
The 15.3% figure is the sum of three separate levies — Oregon state, Multnomah County, and City of Portland transient lodging taxes — that the hotel collects together. You can override the rate if a future change or a specific property differs.
Example and tips
A $200 room for 3 nights has an $600 subtotal, adds about $91.80 in lodging tax, and totals roughly $691.80. Watch for separately stated resort or destination fees: those are not part of the room rate this tool taxes, so add them after the fact. When comparing booking sites, always compare post-tax totals, since the advertised nightly rate hides this 15.3% addition.
