Formula and example
What to calculate it on
The usual base is real-money bets minus wins over the period. The alternative is deposits minus withdrawals. It is simpler, but it also pays out on money that is still sitting on the balance and has not been lost.
In the terms, state the base, the period and what is excluded: bets with bonus money, cancelled bets, specific games.
What it costs the casino
Cashback paid as cash or with a low wagering requirement almost all turns into real money, so its cost is close to the amount credited. 10% of losses is about 10% of the player's GGR.
Count cashback in Bonus Rate together with all other bonuses. For big players cashback is often cheaper than deposit bonuses: it is easy to calculate, and it carries no risk of a big win on bonus money.
How to present it
- Say it plainly: 10% cashback. No "up to 10%": players do not like guessing how much they will get.
- Banners do not use the word "loss": they say "cashback" or "money back".
- Show when it is credited and how much has already built up: that way cashback works as a reason to come back.
