Casino Bonus Wagering Calculator: What Does 30× Mean?
A casino bonus advertised with a 30× wagering requirement must be played through before the bonus, or winnings tied to it, become eligible for withdrawal. The key question is: 30 times what? Depending on the offer, the multiplier may apply to the bonus alone or to the deposit and bonus combined.
A wagering requirement measures the total value of qualifying bets placed. It does not mean you must win 30 times, and completing it does not guarantee that you will have money left to withdraw.
How to calculate a 30× wagering requirement
Start by checking which amount the offer uses as its base. Then multiply that amount by 30.
Suppose you deposit $100 and receive a $100 bonus:
| What the 30× applies to | Calculation | Required qualifying bets |
|---|---|---|
| Bonus only | $100 × 30 | $3,000 |
| Deposit plus bonus | ($100 + $100) × 30 | $6,000 |
Both offers may be described as “30×,” yet the second requires twice as much qualifying wagering. Read the promotion’s terms to identify the base amount before using a calculator. Operators’ rules can differ; for example, DraftKings describes playthrough based on matched bonus funds and the multiplier stated in the particular offer.
How game contributions change the calculation
A $10 bet does not always reduce the requirement by $10. Promotions may count only a percentage of bets on certain games.
For a $3,000 requirement, the amount you would need to wager if every bet were on one game type looks like this:
| Game contribution | Amount wagered to make $3,000 of progress |
|---|---|
| 100% | $3,000 |
| 20% | $15,000 |
| 0% | The bets make no progress |
These percentages are illustrations, not universal rules. Some operators publish different contribution rates for slots, blackjack, live games, and other categories; a game with a 0% rate may make no progress at all. Check the eligible-game list for your specific offer.
You can also calculate what remains when you have played several games. Suppose your original requirement is $3,000. You wager $900 on games contributing 100% and $200 on games contributing 20%:
Remaining requirement = $3,000 − $940 = $2,060
If all your subsequent bets contribute 20%, you would need to wager another $10,300 to make $2,060 of qualifying progress. That figure describes betting volume, not an additional deposit you must make. Whether your balance lasts long enough depends on the outcomes of your bets.
What a wagering calculator can—and cannot—tell you
A simple calculator needs four inputs: the deposit, the bonus amount, the wagering multiplier, and the contribution rate of the games you plan to play. It can estimate your required betting volume and track the progress you have made.
It cannot predict your final balance. A bet may count toward playthrough whether it wins or loses, while the money available for your next bet changes with each result. Meeting a $3,000 requirement does not mean you receive $3,000.
Check the other bonus terms
Before accepting an offer, look beyond the multiplier. Check when the bonus expires, which games are eligible, whether a maximum bet applies, and whether winnings are capped. Also check what happens to bonus funds and related winnings if the deadline passes or you cancel the promotion. These details affect what, if anything, you can withdraw.
Location matters, too. Since January 19, 2026, Great Britain’s gambling rules have limited wagering requirements on incentives offered by licensed operators to a maximum of 10× the incentive amount. A 30× example is therefore a way to explain the calculation; it should not be taken as a currently permitted promotional term for a Great Britain–licensed offer. Rules elsewhere may differ.
Quick check: Identify the amount the multiplier applies to, calculate the required playthrough, and then account for each game’s contribution rate. A large bonus figure on its own tells you little about how much wagering the offer requires.
