Bonus maths

30x wagering on a $50 bonus is $1,500 of bets

“What does 30x wagering mean?” is the question under every welcome banner. Here is the arithmetic with a $50 bonus, then the place the percentage lies to you: the cap.

If you would rather type your own numbers than follow mine, the wagering calculator does the same sums, including the game-weighting step and what the turnover is expected to cost you.

Bonus only

You receive a $50 bonus. The terms say 30x wagering on the bonus. The target is 50 × 30 = $1,500 in qualifying bets. Your $50 deposit is not inside that sum. You still have to bet one thousand five hundred dollars before the bonus turns into withdrawable cash, and slot contribution may be 100% while table games count less or nothing. A game that contributes 0% does not move the target.

Bonus plus deposit

Same $50 deposit and $50 bonus, but the terms say 30x on deposit plus bonus. The base is $100. The target is 100 × 30 = $3,000. Same sticker, double the work, because one sentence changed. I do not assume which sentence a brand uses. I read it.

The cap, before the multiple

JoyCasino’s small first band says 200% with a $25 cap. A $20 deposit would “deserve” a $40 bonus and does not get it. You wager whatever bonus arrived, not the fantasy bonus. Casino-X step one says 100% with a $50 cap, so an $80 deposit still produces a $50 bonus. Then ×30 on that $50 is the $1,500 above, if the multiple is on the bonus alone. Those two offers are written out in the JoyCasino band note and the Casino-X 400% note.

A clearing rate people skip

Suppose a slot returns 96% and contributes fully. On $1,500 of bets the expected loss is about 4% × 1,500 = $60. The $50 bonus does not cover the expected loss of clearing it. That is why a “free” match can still cost money, and why I size a welcome against the bankroll I already meant to risk. If the volume scares you, decline the bonus and play with the deposit only.

18+ only. Set a loss limit first: responsible gambling.

Questions people actually type

Does 30x mean I must bet 30 times my deposit?

Only if the terms say the deposit is inside the base. Many welcomes multiply the bonus alone. A few multiply bonus plus deposit. Those are different targets. The cashier line is the one that counts.

Does a 200% match change the wagering sum?

It changes the bonus, until a cap cuts it. Wagering is then a multiple of whatever bonus you actually received, not of the percentage on the banner.

Is a lower multiple always better?

A ×15 multiple on a bonus you did not want is still money you have to bet. Skip the offer if you would not play that volume with your own cash.
