Average stay calculator

Average stay is total nights divided by the number of reservations — not by 365, and not by occupied days. If that average is 7 nights or fewer, the property falls outside the definition of a rental activity, which is the first of several gates a loss has to pass.

Every night a paying guest stayed, added up across the year.

Separate bookings — not guests, and not nights.

Average stay

4.58 nights

This is 7 nights or fewer, so the property is outside the definition of a rental activity under the seven-day exception. That clears one gate only — the loss is still passive unless you also materially participate.

How this was computed

284 nights ÷ 62 reservations = 4.5806. Not divided by 365, and not by the number of days the property was occupied.

Reg. §1.469-1T(e)(3)(ii)(A) average period of customer use = total days of use ÷ number of periods of use

Common questions

How is average stay calculated?
Total nights booked divided by the number of reservations. It is not divided by 365, and not by the number of days the property was occupied. A property with 284 nights across 62 reservations averages 4.58 nights.
Does an average stay of 7 days or fewer make my losses non-passive?
No, and this is the most common misunderstanding. It removes the property from the definition of a rental activity, which clears one gate. You must separately materially participate under one of the seven tests before a loss can offset other income.
Which reservations count toward the average?
Periods of customer use during the tax year. Nights you or your family stayed are personal use, not customer use, and they are handled by a separate rule under section 280A.
What if my average is over 7 days?
The seven-day exception does not apply, but two other routes remain: an average of 30 days or fewer where significant personal services are provided, and real estate professional status with material participation.

Clearing the seven-day test only opens the door. The hours test is what decides whether the loss reaches your other income — check it with the material participation checker, or model the whole year in the estimator.
