Small-hotel and boutique-inn operator economics

Hotel / B&B Operations Calculators

Operator economics for independent small hotels, bed-and-breakfasts, and boutique inns — STR-standard rooms KPIs (ADR, occupancy, RevPAR, RGI vs comp set), PAII-calibrated contribution-margin breakeven, Kalibri Labs OTA vs direct channel economics, and the stacked state/county/city transient occupancy tax framework. Distinct from the vacation-rental cluster: targets traditional lodging with on-site innkeeper labor and front-desk operations.

Anchored to: STR / CoStar KPI definitions; PAII Industry Study of Operations and Finance; Kalibri Labs Demand360 channel-mix research; Fla. Stat. §§ 212.03 + 125.0104; Cal. Rev. & Tax. Code § 7280; Texas Tax Code Chapter 156

Smith Travel Research (STR

Hotel RevPAR / ADR / Occupancy Reconciliation Calculator

Compute the three industry-standard rooms KPIs every hotel GM, revenue manager, and asset manager reads first: Average Daily Rate (ADR), occupancy, and Revenue Per Available Room (RevPAR). Reconciles RevPAR two ways — direct from total revenue and via the ADR × Occupancy identity — to surface PMS data-feed issues. Computes Revenue Generation Index (RGI) against a supplied competitive-set ADR using the Smith Travel Research (STR) convention. Standard rooms-only computation; F&B, spa, and ancillary revenue are not included. Use for daily flash reports, weekly forecasts, monthly STAR-equivalent benchmarking, and asset-management oversight on small hotels, B&Bs, and boutique inns.

PAII (Professional Association of Innkeepers International) Industry Study of Operations and Finance — biennial owner-operator survey covering ADR

Bed-and-Breakfast / Boutique-Inn Breakeven Occupancy Calculator

Compute the breakeven occupancy a bed-and-breakfast or boutique inn needs to cover its full monthly fixed-cost stack — mortgage or lease, commercial insurance, property tax, utilities, innkeeper salary or owner draw, software subscriptions, and marketing baseline — given an Average Daily Rate (ADR) and the per-room-night variable cost (breakfast COGS, linen, amenities, OTA commission, credit card processing). Returns contribution margin per room-night, breakeven room-nights per month, breakeven occupancy as a percentage, and projected monthly and annual profit at a target occupancy. Calibrated against PAII (Professional Association of Innkeepers International) industry survey ranges for owner-operated B&Bs.

Kalibri Labs Demand360 channel-mix and revenue contribution analysis by booking source — the standard data source for cost of customer acquisition by channel in the U.S. hotel industry

Hotel OTA Commission vs Direct Bookings Calculator

Compare the per-booking economics of online travel agency (OTA) channels (Expedia, Booking.com, Airbnb, Hotels.com) against direct-channel bookings (Google Ads, SEO, loyalty program). Returns net retained per booking on each channel, the direct-marketing breakeven cost-per-booking (the spend ceiling before OTA matches direct), the annualized commission and marketing line at a given booking count and channel mix, and a sensitivity table at 0%, 25%, 50%, 75%, 100% direct share. Calibrated against Kalibri Labs Demand360 channel-mix research showing direct bookings typically deliver $20-$80 more per-booking profitable contribution than OTA for branded hotels. Tool for small-hotel and B&B revenue managers evaluating channel-mix strategy.
