Comparator
Casino bonus comparator
Two offers, the same deposit: for each one, the comparator calculates the bonus received, the amount to wager, the requirement converted to the bonus and the average loss expected during wagering. Choose a casino’s published offer or enter the terms yourself.
For a deposit of €100
Example: the same offer, with wagering on the bonus (A) or on the deposit and the bonus (B). Replace them with the offers you are interested in.
| Criterion | Offer A | Offer B |
|---|---|---|
| Bonus received | €100 | €100 |
| Amount to wager | €3,500 | €7,000 |
| Wagering converted to the bonus | x35 | x70 |
| Expected average loss | €140 | €280 |
| Theoretical outcome | −€40 | −€180 |
| Minimum bets (at the maximum bet) | — | — |
Offer A requires €3,500 less in bets than Offer B for this deposit.
What the calculation does not tell you
- The expected loss is a mathematical average over a very large number of bets: a real session can end up higher or much lower, and the balance can fall to zero before the wagering is complete.
- The maximum cashout, the validity period and the excluded games are not compared here: read the terms of each offer.
- Also check the validity period, the maximum cashout and the excluded games: they do not change the amount to wager, but they can change what you withdraw.
- A bonus is never a reason to deposit more than planned. Staying in control
Why compare on an equal deposit
Two bonuses with the same percentage can cost very different amounts. A wagering requirement of x35 on the bonus alone and one of x35 on the deposit plus the bonus do not call for the same amount to wager: for a 100% offer, the second requires twice the amount to wager. The bonus cap changes everything too: beyond it, depositing more no longer increases the bonus.
Reading the result
The amount to wager is the central figure: it sets the expected average loss, equal to the amount wagered multiplied by the house edge (100% minus the RTP of the games played). The theoretical outcome compares this loss with the bonus received.
The minimum number of bets, calculated at the maximum bet allowed, shows how much playing time an offer requires.
What is not compared
The maximum withdrawable win, the validity period and the list of excluded games are not compared here: read the terms of each offer before choosing one. If gambling is no longer fun, see the responsible gambling page: it lists helplines for each country.
