RTP & House Edge Calculator
RTP percentages are hard to feel. This calculator converts them into the number that matters for budgeting: what a session is expected to cost in dollars.
House edge
4.00%
Total wagered
$600.00
Expected loss
$24.00
Expected cost per hour
$24.00
Of $600.00 staked, a 96% RTP game is expected to return $576.00 over the long run.
RTP is a theoretical average over millions of rounds. In a single session, especially on high volatility slots, results can land far above or below this figure.
The formula
Expected loss = bet size × bets per hour × hours × (100% − RTP)
At $1 a spin and 600 spins an hour, a 96% RTP slot is expected to cost $24 per hour, while a 94% slot costs $36 — a 50% difference from a two-point RTP gap. That's why we publish RTP on every game page and track it in our slot RTP statistics.

Frequently Asked Questions
What does RTP mean?+
Return to player (RTP) is the percentage of all money wagered on a game that it is designed to pay back over the long run. A 96% RTP slot returns $96 for every $100 staked, on average, across millions of spins.
How is house edge related to RTP?+
House edge is simply 100% minus RTP. A 96% RTP game has a 4% house edge; a 99.5% RTP blackjack variant has a 0.5% edge.
Why does spin speed matter so much?+
Expected loss scales with total amount wagered, not with time. Doubling your spins per hour doubles your expected cost per hour, even at the same bet size and RTP.
Does volatility change the expected loss?+
No. Volatility changes how widely results swing around the average — how often and how big wins are — but the long-run expected loss is set by RTP and total stake alone.
