Hotel Budget Season Arrives With Booking Costs Outpacing RevPAR by 6 Points

Booking acquisition costs per available room have risen 25% since 2019, while RevPAR over the same period grew only 19% — a gap Duetto’s hotel budget-season guide uses to argue that revenue managers walking into Q3/Q4 planning meetings need a different case than “grow the top line.” The guide, aimed at the annual cycle when properties lock in next year’s tech and staffing spend, frames “performance engineering” as the discipline revenue leaders should bring to budget conversations: evaluate every commercial decision — a rate change, a channel shift, a marketing dollar — by the profit it protects, not the revenue it generates.

That framing isn’t new to Duetto. In an earlier piece, the company put a number on why RevPAR-only budgeting is breaking down: flow-through in the Americas hit just 18% in 2025, meaning less than a fifth of incremental revenue reached the bottom line even as RevPAR kept climbing. The argument there was that two hotels can post identical RevPAR and have very different profitability once channel mix, labor cost, and group displacement are counted — GOPPAR, not RevPAR, is the metric that actually tracks margin.

A follow-up piece names the practical obstacle standing between hotels and that shift: profit data at most properties is scattered across departments and reconciled only monthly or quarterly, too slow to inform daily rate and channel decisions. HotStats CEO Michael Grove and Duetto’s Nick Knight frame the fix as near-real-time profit visibility rather than added revenue-management headcount, pointing to tools like Duetto’s Advance as the mechanism for surfacing profit signals fast enough to act on.

For operators heading into budget season, the throughline across all three pieces is the same: a revenue-management tech request that can’t show its GOPPAR or flow-through impact is going to lose the budget argument to one that can. Booking costs aren’t returning to 2019 levels. The ask has to be framed against margin protection, not top-line growth, or it won’t survive the planning cycle.
