Frequently Asked Questions

Key card economics?

Standard plastic RFID card: $0.12–0.25 each. Premium printed (custom branding): $0.30–0.60. Wood/metal eco card: $1.50–4.00 (luxury hotels). Annual: 200-room hotel uses 25–50k cards/year = $5–15k/yr. Loss rate: 2–5% per stay (guest takes home, lost in laundry, dropped). Replacement: lockout calls add front-desk labor cost. Mobile keys eliminate 70–90% of card usage but most properties still need cards for non-app users.

How does this support hotel underwriting?

Hotel investors and operators use this calculator alongside RevPAR, GOP, and flow-through analysis to validate operating assumptions. Pair it with a comp set benchmark (STR or HotStats data), brand/franchise standards, and seasonal demand patterns. Output is most useful when triangulated against trailing twelve-month financials and a forward booking pace report.

Brand vs independent treatment?

Branded hotels (Marriott, Hilton, Hyatt, IHG, Choice, Wyndham) typically follow USALI 11th edition reporting which dictates how this metric flows through the P&L. Independent and lifestyle hotels have flexibility but most lenders still expect USALI-aligned reporting. Use brand standards or local CVB data when defaults aren't representative of your asset.

Seasonal sensitivity?

Inputs based on annual averages mask peak/shoulder/trough volatility. Resort properties may see 60–80% of annual revenue concentrated in 4–6 months. Urban transient is more even but dips for weekends. Model peak month, shoulder month, and trough month separately if seasonality exceeds 20% swing. Stress test with a 10–15% RevPAR shock for cycle planning.
