UK Expected Value Per Hour Calculator 2026
Different casino games produce different expected loss rates per hour depending on house edge, bet size, and round pace. This calculator computes the expected loss per hour for UK casino games based on your inputs. Comparing hourly loss rates across games reveals why game selection matters more than most players realise — at £5 per round, blackjack expected loss is approximately £1.30/hour while American roulette expected loss is approximately £15/hour for identical time commitment.

Why Hourly EV Matters
Hourly expected value is the most useful lens for comparing casino activity sustainability. Total losses depend on how long you play; hourly rates let you budget time commitment against financial exposure. A £3/hour expected loss rate for 100 hours annually is £300 expected annual loss — a reasonable entertainment expense for many players. A £30/hour expected loss rate for 100 hours annually is £3,000 — substantially different scale.
Comparing Games Across Categories
At £5 per round:
Power Blackjack with basic strategy: 60 hands/hour × £5 × 0.25% = £0.75/hour. The lowest expected loss rate at UK casinos.
Live blackjack with basic strategy: 60 hands/hour × £5 × 0.43% = £1.29/hour. Second-lowest category.
Live baccarat Banker bet: 100 hands/hour × £5 × 1.06% = £5.30/hour. Higher pace partially offsets lower edge.
European roulette: 50 spins/hour × £5 × 2.70% = £6.75/hour.
American roulette: 50 spins/hour × £5 × 5.26% = £13.15/hour. Nearly 2x European.
Slot 96% RTP: 400 spins/hour × £5 × 4% = £80/hour. Slot pace is much faster than table games, producing higher hourly exposure.
This comparison reveals why slots are the highest hourly-exposure category despite competitive RTPs — the rapid pace produces high wagering volume per hour.
Reducing Hourly Exposure
Three levers for reducing hourly expected loss:
Lower bet size. Halving bet halves hourly loss proportionally.
Lower house edge. Play Power Blackjack (0.25%) instead of standard blackjack (0.43%); European roulette (2.70%) instead of American (5.26%); French La Partage (1.35% even-money) instead of standard European (2.70%).
Slower pace. 400 spins/hour slots to 200 spins/hour (deliberate pacing, breaks between spins) halves hourly exposure.
Combining all three can reduce expected loss by 75%+ without reducing total entertainment value.

Frequently Asked Questions
Why does slot hourly EV appear so high?
Slot pace (400+ spins/hour) is much faster than table games (60 hands/hour for blackjack). Higher wagering volume per hour produces higher hourly exposure even at competitive RTPs.
What's the lowest hourly EV at UK casinos?
Power Blackjack with basic strategy: approximately £0.75/hour at £5 per hand. Second-lowest is standard live blackjack at £1.29/hour.
How do I reduce my hourly exposure?
Three levers: lower bet size (proportional reduction), lower house edge (game selection — European over American roulette, Power over standard blackjack), slower pace (deliberate spinning with breaks halves hourly exposure).
Are these values exact?
They're mathematical long-run averages. Individual sessions will vary substantially through variance — some sessions will produce wins, some will produce losses exceeding these averages.
Why is baccarat pace 100/hour but blackjack 60/hour?
Baccarat has no player decisions (all actions are dictated by rules); blackjack has multiple decisions per hand. Decision time slows blackjack pace meaningfully.
