STR Owner Stay Opportunity Cost Calculator

Owner-blocked STR nights have real opportunity cost — quantify during budgeting.

Nights blocked

Seasonal ADR

Seasonal occupancy %

Cleaning fee saved

Variable cost / night

Net opportunity cost

$3,752

Gross forgone revenue

$4,335

Variable costs avoided

$583

How the math works

Foregone revenue = blocked × seasonal occ × ADR. Net = forgone − variable costs.

12 × 85% × $425 = $4,335 gross − ($408 + $175) = $3,752 net opportunity cost.

How to Use

Enter nights blocked for owner use.
Enter seasonal ADR for those nights.

Frequently Asked Questions

What is owner-stay opportunity cost?

Revenue forgone when owner blocks the STR for personal use. Pro-forma owner-stay cost = expected nights rented × ADR − variable costs avoided. Tax implication: owner-use days above 14 or 10% of rental days (whichever greater) convert property to 'mixed-use' under IRC §280A, limiting deductible losses. Plan carefully around threshold.

Seasonal vs annual ADR?

Owner stays often coincide with peak season (Thanksgiving, July 4, December holidays) — when ADR is 2-4× annual average. Opportunity cost should use seasonal ADR × seasonal occupancy, not annual average. Blocking 14 peak nights at $400 × 90% = $5,040 lost revenue, not annual-average $200 × 65% = $1,820. Significant difference.

Variable cost savings?

Owner staying = no cleaning ($75-300 saved), potentially no utilities spike (owner already would be paying), no linen turn, no restocking consumables. Typical variable cost per night: $25-80. Net opportunity cost = gross forgone revenue − cleaning fee ($100-300) − variable costs ($25-80 × nights). On 10-night block: net cost $3-4k vs gross $5-6k.

Tax considerations?

IRC §280A: if owner-use exceeds 14 days OR 10% of fair rental days, property is 'residence' — deductible expenses limited to rental income. Preferred tax structure: 14 days max owner use (safe harbor), or <10% of rental days. Example: property rented 150 nights + 15 owner = 165 total; 15/165 = 9.1% — safe. Exceed threshold: passive loss rules + §280A limits.
