Casinos budget comps like marketing costs because the purpose is usually behavioral: attract a visit, retain a valuable guest, increase trip frequency, shift play to a desired date, or protect a customer relationship from a competitor. The property gives up some value now because it expects profitable activity in return.
That does not mean every comp is posted to one accounting line called “marketing.” Earned loyalty points, discretionary hotel rooms, free play, host-authorized meals, and third-party event tickets can be recorded differently. Operationally, however, management evaluates them as customer reinvestment: what did the benefit cost, what action did it influence, and did the relationship remain profitable after the benefit?
The budget question is not “How generous should we be?”
A comp budget is a controlled allocation of value. The practical questions are:
- Which customers are the property trying to acquire, retain, or reactivate?
- What future visit or behavior is the offer intended to produce?
- What is the player’s expected value to the casino?
- What is the casino’s actual cost of providing the benefit?
- Could the room, seat, or ticket have been sold to someone else?
- Did similar offers produce incremental revenue, or merely reward visits that would have happened anyway?
This is why a casino can value two apparently identical $100 benefits differently. A dining credit has one cost structure. A hotel room on a quiet weekday has another. A sold-out Saturday room has an opportunity cost close to the cash business it displaces. Promotional slot play has wagering conditions and expected redemption behavior that differ from cash.
Four numbers behind a comp decision
1. Expected gaming value
For rated casino play, the common starting point is theoretical loss:
Theoretical loss = total rated action × applicable house edgeFor table games, total rated action may be estimated from average bet, decisions per hour, time played, and the game’s assumed edge. For slots, identified coin-in and the game’s theoretical hold can provide a more direct estimate. The comp-calculation explanation covers those mechanics.
Theo is not the player’s actual result. A player can win while generating substantial theoretical value, or lose heavily while generating little. Budgeting from expected value reduces the chance that one unusually lucky or unlucky trip determines the entire relationship.
2. Reinvestment
A simple planning ratio is:
Reinvestment rate = comp value allocated ÷ theoretical lossIf a customer group is expected to generate $40,000 of theoretical loss and the approved benefits assigned to that group are valued at $8,000, the modeled reinvestment rate is 20%.
That ratio is only meaningful when “comp value” is defined consistently. Some operators use retail value for communication, incremental cost for budgeting, or a standardized internal value for host authority. Mixing those bases makes one department look generous and another look efficient even when the economics are the same.
3. Incremental cost
The amount printed on the offer is not necessarily what the casino spends to fulfill it.
| Benefit | Face value seen by guest | Costs management may consider |
|---|---|---|
| Hotel room | Public room rate | Cleaning, amenities, utilities, labor, and displaced cash demand |
| Food credit | Menu price | Food cost, labor, tax treatment, outlet capacity, and displaced sales |
| Free play | Promotional balance | Expected gaming cost, redemption, eligible games, and additional paid play |
| Event ticket | Ticket price | Purchased cost or opportunity cost of a sellable seat |
| Gift | Suggested retail value | Procurement, freight, storage, staffing, and unclaimed inventory |
A room that would otherwise sit empty can be a low incremental-cost retention tool. The same room during a high-demand event may be an expensive comp because it replaces a likely cash booking. Good comp controls therefore change with date, inventory, outlet capacity, and customer value.
4. Incremental contribution
The property ultimately needs to know whether the campaign added profitable business:
Incremental contribution
= incremental gaming revenue
+ incremental non-gaming margin
− incremental comp cost
− campaign and servicing costEvery variable refers to activity caused by the offer, not all activity observed during the trip. If a guest would have visited and played the same amount without the offer, crediting the full trip to the campaign overstates performance.
Imagine a reactivation campaign sent to a lapsed customer group. The group produces an estimated $30,000 of incremental gaming revenue and $4,000 of incremental non-gaming margin. Fulfilled benefits cost the property $7,000, and communication and event servicing cost $2,000:
Incremental contribution = $30,000 + $4,000 − $7,000 − $2,000
Incremental contribution = $25,000This does not prove each recipient was profitable. It says the campaign, as defined and measured, produced a positive modeled contribution. Management would still examine redemptions, customer segments, future trips, and any high-cost outliers.
Why comps are more targeted than ordinary advertising
A billboard pays to reach a broad audience. A player offer can be directed to an identified person whose prior activity, preferences, visit dates, and response history are known. That makes the offer measurable in ways that mass advertising often is not.
A casino can test:
- free play versus dining credit;
- weekday versus weekend valid dates;
- one large offer versus several smaller visits;
- a room offer versus an event invitation;
- retention treatment for a declining player;
- reactivation treatment for someone who has stopped visiting;
- benefits aimed at gaming value versus total resort value.
The objective is not always maximum play on the next trip. An integrated resort may want hotel, dining, entertainment, or cross-property activity as well. A high-value customer relationship can be judged across several departments and over more than one visit. That is why customer lifetime value differs from the result of one session.
MGM Resorts’ current annual report places its loyalty program inside its marketing strategy and says customer data and analytics are used to personalize offers, segment guests, drive incremental visits, and strengthen long-term relationships. The same filing also shows why “marketing cost” is an operational shorthand rather than a complete accounting description: loyalty incentives can create deferred revenue obligations, while discretionary goods and services are allocated or expensed according to the nature of the transaction.

What an effective comp budget prevents
Without limits and ownership, comping can fail in opposite directions.
Under-reinvestment can cause a property to lose profitable guests over benefits that a competitor is willing to provide. It can also make the loyalty program feel arbitrary when similar customers receive inconsistent treatment.
Over-reinvestment can fill rooms, restaurants, and casino floors with activity that does not cover the cost of the benefits. Volume can look healthy while margin deteriorates. This is the same reason a busy casino can still make less money.
Controls normally include authority levels, customer-value thresholds, inventory rules, offer codes, redemption tracking, exception approval, and post-campaign review. A host may be able to issue a meal but need higher approval for airfare or a premium suite. The purpose is not to remove judgment. It is to make judgment visible and comparable.
Why free play is common
Free play directs the benefit back into gaming, can be restricted by date and machine eligibility, and is easy to connect to account activity. It can also generate a return visit during a chosen period. Those features often make it more controllable than handing the customer an equivalent amount of unrestricted cash.
The player should still distinguish promotional amount from cash value. Rules may require the credit to be wagered, and the resulting cashable amount is uncertain. Why casinos give free play instead of cash examines that distinction from the offer-design side.
The player-side interpretation
A comp is evidence that the casino believes the relationship has value, not evidence that previous losses have been refunded. The property expects the offer to influence future behavior or preserve loyalty. A player can accept the benefit without accepting the implied invitation to gamble more.
Value the room, meal, or event at what it is genuinely worth to you. Compare that value with the expected cost and additional activity caused by the offer. The safest use of a comp is to reduce the cost of a visit you had already budgeted, not to justify a trip, stake, or session length you would otherwise reject.
That is the core reason casinos budget comps like marketing: the benefit is an investment in customer behavior, and investments are supposed to have a defined purpose, a controlled cost, and a measurable return.
