The illustrative cost is required turnover multiplied by the edge you enter. It ignores variance, limits, expiry, max bets, cashout caps, fees, and the possibility that the promotion is unavailable in your jurisdiction.
What this tool makes visible
The calculator separates the bonus from the wagering base, then estimates a theoretical game cost using the edge you enter. It also shows how many days the requirement would take at your planned daily turnover. Use the exact contribution and base from the current promotion.
What it does not decide
It does not verify a casino, predict your results, interpret every contract clause, or account for variance, maximum bets, expiry, cashout caps, fees, or local rules. For the full terms walkthrough, read Casino Bonus Terms Explained. For the operator-level checks, use the Terms Checklist.
Use a bonus as an optional promotion
Do not increase the deposit, daily turnover, or session budget to chase a bonus. Keep your spending boundary separate from promotional money and use the Session Budget Calculator before play.
What does the illustrative cost mean?
It multiplies the required turnover by the game edge you enter. It is a long-run-style arithmetic reference, not a prediction of your personal result or a promise that the bonus will offset losses.
Why does contribution matter so much?
A game contributing 10% reduces the requirement one tenth as quickly as a game contributing 100%. The actual terms may also exclude games or apply different rates to different bets.
Should I accept a bonus if the result is positive?
Not automatically. Check max bets, expiry, cashout caps, withdrawal rules, eligibility, licensing, and whether the offer changes your spending plan. A positive illustration is not a recommendation.
