Required qualifying turnover equals the applicable wagering base multiplied by the wagering requirement. If a game contributes less than 100%, the total stake needed is higher. Turnover is not the amount you must lose and not a prediction of what you will win.
Identify the base first
An offer described as 35× might apply to the bonus alone, or to the deposit plus bonus. Those are different requirements. In an illustrative offer with a $100 deposit and a $100 bonus, 35× bonus means $3,500 of qualifying turnover. The same multiplier on deposit plus bonus means $7,000. Neither number is an estimate of the final balance.
Then read contribution
Games can contribute different percentages to an offer’s wagering target, and some may be excluded. If a game contributes 20%, $100 staked contributes only $20 toward a qualifying target. A $3,500 target would therefore require $17,500 of total stakes through that game, assuming the rules allow it and the contribution stays constant.
Do not overlook the other rules
A wagering multiplier is only one part of a promotion. Record the maximum stake, expiry, eligible games, restricted betting patterns and maximum conversion or cashout. Check what happens if you withdraw early or mix bonus funds with a real balance. Always use the offer shown in your account and the linked terms rather than a third-party banner.
Turnover is not deposit size
The same funds can be wagered repeatedly, so a turnover target is not a requirement to deposit that amount. Equally, there is no assurance that your starting balance will survive long enough to complete it. Wins and losses can vary considerably, and a deadline should never become a reason to exceed a spending limit.
Use the calculator as a translation tool
The calculator below turns an assumed base, multiplier and contribution into an arithmetic target. It does not judge whether an offer is worthwhile, model the probability of completing it, include every restriction or forecast an outcome. If the terms say different games contribute differently, calculate the relevant scenarios separately.
Declining is a valid choice
A bonus is optional. If its conditions are hard to understand or encourage more play than you intended, you can leave it unclaimed. Even without a promotional bonus, an operator may have standard deposit and withdrawal conditions. Check those separately before funding.

Amounts use the same unit you enter. Example inputs are illustrative. Turnover is not expected loss. Expiry, maximum bets, exclusions and cashout caps are not modelled.
