How the math works

Flow-through = ΔGOP / ΔRevenue.

($13.5M − $12M) = $1.5M revenue Δ. ($5.9M − $5M) = $900k GOP Δ. $900k / $1.5M = 60% flow-through.

Frequently Asked Questions

Flow-through benchmarks?

Healthy: 50–65% flow-through (each $1 incremental revenue → $0.50–0.65 GOP). Excellent: 70%+. Below 40%: cost discipline failing. Drivers: variable cost discipline (housekeeping, F&B), price-led growth (better than volume-led), rate vs occupancy mix. Flow-through targets in management contracts: incentive fees often tied to >55% flow-through. Underperformance triggers reforecast + cost cut programs.

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.
