Expected loss calculator
What does a session cost on average? Multiply the stake by the number of bets to get the turnover, and the house edge takes its share of that. Lock a title to use the RTP in our casino data.
Optional. Pick a casino and a title, and the calculator uses the RTP in our data for it. Only titles with an RTP figure are listed.
A generic value. Change it to the RTP your game shows.
Any unit works: the result is in the same unit.
The same turnover at different RTP levels
| RTP | House edge | Expected loss | Paid back |
|---|---|---|---|
| 99.0% | 1.00% | 10 | 990 |
| 98.0% | 2.00% | 20 | 980 |
| 97.0% | 3.00% | 30 | 970 |
| 96.0% | 4.00% | 40 | 960 |
| 95.0% | 5.00% | 50 | 950 |
| 94.0% | 6.00% | 60 | 940 |
| 90.0% | 10.00% | 100 | 900 |
How expected loss is worked out
The RTP is the share of all money wagered that a game pays back over a very large number of rounds. The rest is the house edge. The expected loss is that edge applied to everything you wager, which is the turnover and not the deposit: money that is won and bet again counts each time.
Worked example
1,000 bets of 1 make a turnover of 1,000. At an RTP of 97.00% the house edge is 0.03 per 1 wagered, so the expected loss is 30. The same turnover costs 10 at 99.00% and 60 at 94.00%.
To see which title of a game type costs the least, open the house edge comparison. The average says nothing about whether the balance lasts, which is what the bankroll survival odds are for. Stakes in satoshi or mBTC can be converted first with the bet unit converter.
What an expected loss is not
- It is an average over many sessions, not a forecast for one. A single session can end well above or far below it.
- It does not depend on the staking plan. Any way of spreading the same turnover has the same expected loss.
- The RTP of a locked title is a figure we read: in the casino lobby, inside the game or from published figures. We do not measure it ourselves, and a provider can ship the same title with a different RTP elsewhere.
Questions about expected loss
Why is the loss based on turnover and not on my deposit?
Because the edge applies to every bet. A deposit of 100 that is bet ten times over is a turnover of 1,000, and the edge takes its share of all of it.
How much does one point of RTP cost?
One unit per 100 wagered. On a turnover of 1,000 the expected loss is 10 at 99.00% and 30 at 97.00%.
How much can I wager on a budget of 50?
Divide the budget by the house edge. At 97.00% a budget of 50 is used up, on average, after a turnover of 1,667.
Can I lose less than the expected loss?
Yes, and also more. The expected loss is the centre of a wide range. The more bets you place, the closer the result per unit wagered tends to move towards the edge.
