Customer acquisition cost

What is Customer Acquisition Cost in hotels?

CAC is the average amount your property spends on sales and marketing to win one new direct guest. It rolls up paid media, OTA commissions, travel-agent fees, sales-team cost, booking-engine spend and the technology stack that makes the conversion happen, then divides it by the number of new guests acquired.

It’s the most honest measure of marketing efficiency a hotel has. Almost every other marketing KPI (CTR, conversion rate, revenue per click) is a leading indicator. CAC is the lagging, audited number that decides whether the spend is sustainable.

CAC formula

Why CAC matters for hotels

Hotels that don’t track CAC tend to over-fund whichever channel was loudest last quarter, typically OTAs because the commission is invisible until month-end. Tracking CAC by channel forces the comparison: a 20% OTA commission on a $200 ADR booking is a $40 CAC; spending the same $40 on direct paid often returns far better long-term economics.

• Channel comparison: OTA vs direct vs metasearch vs travel agent on the same per-guest basis.
• Financial planning: bake CAC into rate strategy so each segment is priced above its acquisition cost.
• ROI insight: paired with guest LTV, CAC tells you whether each channel is sustainable.
• Growth strategy: reduce wasted spend by killing channels with poor LTV:CAC and doubling down on the rest.

CAC vs CLV: the profitability equation

CAC only becomes useful when paired with Customer Lifetime Value (CLV), the total revenue you expect to earn from a guest across every stay. The widely accepted benchmark is a CLV:CAC ratio of at least 3:1, meaning every dollar of acquisition spend should return at least three dollars of long-term revenue.

A CLV:CAC ratio under 3:1 is a sustainability warning. Above 5:1, you’re probably under-investing in growth and could safely spend more to acquire more guests. The right ratio is the one that matches your market position and the speed at which you want to scale direct demand.

Strategies to reduce CAC

• Shift budget toward high-ROI channels: your direct website, retargeted leisure, returning-guest email.
• Improve booking-engine conversion with simpler checkout, fewer steps and clear value props above the fold.
• Recover abandoned bookings with email/SMS triggers before the OTA wins the same guest.
• Lift repeat-direct rate via loyalty, post-stay flows and pre-arrival upsells. Repeat guests have near-zero CAC.
• Match paid spend to seasonal demand pace instead of running flat budgets year-round.
