Deposit bonus percentage
A deposit bonus percentage is the share of your qualifying deposit that a casino or bookmaker adds to your account as bonus funds, usually up to a stated maximum. A 100% match on a €50 deposit adds €50 of bonus money; a 50% match on the same deposit adds €25. The figure tells you how the bonus is sized, and nothing about what it will cost you to clear it.
How the percentage is calculated
The formula is plain: bonus equals deposit multiplied by the match percentage, then cut back to the cap. On “100% up to €100”, a €300 deposit still earns €100, so the effective rate on that deposit is about 33%.
Above the cap, extra money converts at nothing.
You meet the figure in the offer headline, and again in the terms, where the minimum qualifying deposit and the maximum bonus sit beside it. Percentages of 50%, 100% and 200% are common, but there is no fixed standard, and operators set their own caps and minimums. A 200% match on €40 gives you €80 of bonus funds, which looks larger than a 100% offer until you read what is attached to it.
Percentage versus wagering base
The percentage is often read as the value of the offer. It is not; the wagering requirement and its base decide that.
Take a €100 deposit with a 100% match and 35x wagering. If the clause says “35x the bonus amount”, you need €3,500 of bets. If it says deposit plus bonus, the base doubles to €200 and you need €7,000, which makes the second offer clearly worse despite an identical headline.
So when you compare two deals, set the percentage aside for a moment and multiply out the wagering in euro first, checking the max bet rule and any cap on winnings while you are in the terms.
