Average stay / 7-day rule calculator
Estimate your average period of customer use — the first half of the common short-term rental non-passive path under Treas. Reg. §1.469-1T(e)(3). Add each booking's nights; we divide total days by number of stays.
Educational estimate only — not tax, legal, or financial advice. How your platform counts nights vs calendar days can matter; confirm with a CPA. Entries stay in this browser until you export or clear them.

Add at least one stay to calculate average customer use.
- ≤ 7 days — usual first half of the STR path
- ≤ 30 days — different exception; significant services may matter
- > 30 days — typically longer-term rental treatment
Average = total days of customer use ÷ number of stays (periods of use). Meeting ≤ 7 days does not by itself make losses non-passive — you still need material participation.
