Casino game speed and expected loss: calculating your ‘cost per hour’

In a casino, the most practical way to budget is to translate house edge into a time-based figure: your expected loss per hour, sometimes called “cost per hour”. It is not a prediction of what you will lose in a session, but a long-run average based on maths. The core idea is simple: expected loss per hour equals your average stake per bet multiplied by the number of bets you make per hour, then multiplied by the game’s house edge. Once you can estimate those three inputs, you can compare games on a like-for-like basis and choose a pace that suits your risk tolerance.

Game speed is the lever most players overlook. A low-edge game can still be expensive if it is fast, while a higher-edge game may cost less per hour if it is slow and you keep stakes modest. For example, if you wager £10 per spin at 500 spins an hour on a 4% slot, your expected loss is £10 × 500 × 0.04 = £200 per hour. Change only the pace to 200 spins an hour and the expectation drops to £80. Table games vary widely: blackjack might be 60–100 hands an hour, roulette 40–60 spins, and live-dealer formats can be slower still. Track your real pace for ten minutes, scale it to an hour, and you will have a usable estimate.
