RTP Expected Loss Calculator
Estimate a session's theoretical loss: bet per spin × spins × (100 − RTP).
How it works
Expected loss turns RTP into a concrete number: how much a session costs you on average. The house edge is (100 − RTP): on every euro staked at 96% RTP, the game keeps about 4 cents on average. Multiplied by spins and bet size, you get the theoretical loss.
Note: RTP is measured over millions of rounds. In the short run volatility dominates — which is why you can finish well ahead or bust even on a high-RTP title. The calculator gives you the mathematical expectation, not a forecast of a single night.
