How This Comp Calculator Works

Casino comps — free play, meals, resort credit, and free rooms — are not handed out based on whether you win or lose. They are handed out based on your theoretical loss, the amount the casino expects to earn from your play over time. This calculator reproduces that same calculation so you can see roughly what your session is worth to a property before you ever talk to a host.

The formula behind the estimate

Every result on this page comes from one line of math:

Average bet × decisions per hour × hours played × house edge = theoretical loss

Estimated comp value = theoretical loss × the property's reinvestment rate

Decisions per hour are the pace assumptions built into the calculator: roughly 500 spins per hour on slots and video poker, 100 rolls on craps, 70 hands on blackjack and baccarat, 45 spins on roulette, and 35 hands on pai gow poker. The house edge figures are industry-typical: about 8% on slots, 1% on blackjack, 1.4% on baccarat and craps, 2% on video poker, 2.7% on pai gow poker, and 5.3% on double-zero roulette.

The reinvestment rate is the share of your theo the casino gives back. The calculator uses ranges drawn from documented program behaviour: roughly 30–40% at Station Casinos, 35–45% at South Point, 25–35% at Boyd and the larger tribal programs, and 15–25% at Caesars and MGM, where a bigger share of your value is returned as room rates and amenities rather than free play.

A worked example

Say you play blackjack at a $10 average bet for 3 hours. At 70 hands per hour that is 210 hands, or $2,100 in total action. Multiply by the 1% house edge and your theoretical loss is about $21. At a generic 20–30% reinvestment rate, that session is worth roughly $4 to $6 in comps — enough for a coffee shop credit, not a room.

Now change one input. The same $10 average bet on slots for 3 hours is 1,500 spins at an 8% edge, which is about $1,200 of theoretical loss — and $240 to $480 in expected comps at the same rate. That gap is the single most important thing this calculator shows: game choice moves your comp earning rate far more than bet size does, and it moves your expected cost by exactly the same amount.

Use the numbers to decide whether an offer you have been sent is generous or thin, and to see what level of play would actually be required to earn the room or free play you are chasing. Never increase your bet or your hours to reach a comp target — the comp is always worth less than the extra expected loss required to earn it.

Comp Calculator FAQs

Theoretical loss (usually shortened to 'theo') is the amount the casino mathematically expects to win from your play over the long run. It is calculated from how much you bet, how many decisions you play, and the house edge of the game — not from whether you personally won or lost that trip. Casinos use theo because it is stable and predictable: a player who bets $25 a hand for four hours has the same value to the property whether they walked out up $800 or down $600. That is why you can have a winning trip and still receive a strong offer in the mail.

It is an estimate, not a quote. The math behind the theoretical loss figure is the same math casinos use, but every property sets its own reinvestment percentage, and that percentage can change with your visit frequency, how long you have been in the program, the day of the week you play, and whether you are considered a new or reactivated player. Treat the output as a realistic range to sanity-check the offers you already receive.

Usually yes, per dollar wagered. Comps are tied to theoretical loss, and a low-edge game produces less theo per hour than slots at the same bet size. That does not make low-edge games a bad choice — you keep more of your bankroll — it just means the comps come more slowly. Many table game players offset this with longer sessions or slightly larger average bets.

Because reinvestment rates differ widely. Locals-focused operators in Las Vegas typically return a much larger share of theo than Strip resorts, which compete on rooms and amenities rather than free play. That is why the calculator lets you pick a property type: the theoretical loss stays the same, but the comp range shifts based on how generous that program historically is.
