Check What a Bonus Really Costs

Enter the bonus amount and the multiplier from the terms. The calculator shows the total you must stake before a withdrawal is allowed.

Your bonus

How much real money you deposit to trigger the bonus.
$
The percentage of your deposit the casino matches as bonus funds. 100% doubles your deposit.
The cap on how much bonus money you can receive. Set 0 for no cap.
$
How many times the base amount must be wagered before the bonus can be withdrawn.
Deposit plus bonus nearly doubles the real turnover versus bonus only. Winnings applies to what the bonus generates; the bonus amount is used as the base here.
How much of each bet counts towards wagering. At 20% you must stake 5 pounds for every 1 pound of required turnover.
Your typical stake per spin or hand while clearing the bonus.

How it works

From Terms Page to Score in Four Steps

The pipeline is boring on purpose. Boring is auditable.

  1. Paste the terms

    The bonus terms URL goes into our analyser exactly as the casino publishes it.

  2. We extract the facts

    The multiplier, window, weighting table, caps, and exclusions come out as structured data a human editor verifies.

  3. We score claim ease

    Fixed weights turn those facts into a 0 to 100 score and a letter grade. No editor can nudge it.

  4. You see the catch

    Every flagged clause appears on the review next to the score, quoted from the rule that triggered it.

Common misconceptions

Casino Bonus Questions, Answered Straight

The six misunderstandings that cost players the most money, cleared up in plain language.

Is bonus money the same as real cash?

No. Bonus funds sit in a separate wallet with their own rules. You usually cannot withdraw them, and winnings made with them stay locked until the wagering requirement is finished. Only then do they convert to withdrawable cash, sometimes with a cap on how much converts.

What does 35x wagering actually mean?

It means you must stake 35 times the bonus amount before withdrawing. A $100 bonus at 35x requires $3,500 in total bets. If the multiplier applies to deposit plus bonus, the number doubles again. Our calculator does this math for any offer.

Why would a casino void my winnings over one bet?

Most bonuses carry a max bet rule, commonly $5 per spin or hand, while wagering is active. A single bet above the limit can void the bonus and every win made with it. It is one of the most common hidden clauses we flag, because it never appears in the headline offer.

Do all games count towards wagering?

Rarely. Slots typically contribute 100%, while table games and live dealer often count 10% or nothing at all. Playing blackjack against a 100% slots weighting means you clear wagering ten times slower than you think, or not at all.

Can I just withdraw the bonus right after claiming it?

No, and trying can end the bonus. Withdrawing before wagering is complete typically forfeits the bonus and any winnings tied to it. Some casinos also exclude deposits made with certain payment methods from qualifying in the first place.

What is a max cashout cap?

A ceiling on what you can withdraw from bonus winnings, common on no deposit and free spin offers. Win $2,000 from a bonus with a $100 cap and $1,900 of it is removed at withdrawal. Caps weigh heavily in our claim ease score for exactly that reason.
