Wagering Requirement Calculator

Understanding wagering requirements and bonus rollover

This wagering requirement calculator translates casino bonus terms into clear numbers: how much you need to wager in total and how much you are likely to lose on average based on the RTP of the games you choose.

How wagering requirements affect your bonus value

A large bonus with a very high rollover can be less valuable than a smaller bonus with fair terms. The higher the multiple and the wider the base (bonus + deposit instead of bonus only), the more you will have to wager - and the more house edge you will face before you can cash out.

Why RTP is crucial when clearing wagering

• Higher RTP games (for example 96% or more) generally reduce your expected loss while working through the rollover.
• Low RTP games or side bets can dramatically increase your effective cost of clearing the bonus.
• Some casinos exclude certain high-RTP titles from wagering - always double-check the terms before you start playing.

Practical strategy for clearing wagering requirements

• Use this calculator before claiming a bonus to see if the required turnover is realistic for your bankroll and bet size.
• Avoid very high wagering multiples on combined bonus + deposit if your bankroll is small or you prefer lower risk.
• Track your play and compare real losses to the expected loss to better understand the true cost of different bonus offers.

Common Mistakes

• Not reading which games contribute to wagering requirements — most casinos count slots at 100% but table games at only 5-10%. Playing blackjack thinking it counts fully towards wagering can leave you with thousands more to wager than expected.
• Playing high-volatility slots hoping to 'get lucky' and clear the bonus with a big win — while possible, the mathematically optimal approach is to grind with high-RTP, low-volatility slots to minimise variance and maximise the chance of having funds left when wagering is complete.
• Ignoring maximum bet limits during bonus wagering — most casinos impose a max bet (typically £5-£10) while wagering. Exceeding this limit can void your bonus and any winnings. Always check the terms before playing.

Worked Examples

Standard Casino Bonus

You receive a £50 bonus with a 35x wagering requirement on a minimum deposit of £20. Enter bonus £50, deposit £20, wagering multiplier 35x, and slot RTP 96%. The calculator shows total wagering required is £1,750, and your expected loss from wagering is £70 (4% of £1,750). Since the expected cost (£70) exceeds the bonus value (£50), this bonus has a negative expected value of -£20. You'd statistically lose money by accepting it.

High-Roller Bonus Evaluation

A casino offers a €200 bonus with a 40x wagering requirement. Enter bonus €200, wagering 40x, and RTP 96%. Total wagering needed is €8,000, with an expected loss of €320 (4% of €8,000). The expected cost (€320) far exceeds the bonus (€200), making this a -€120 proposition. Higher wagering multipliers make bonuses exponentially worse — compare this 40x offer to a 20x offer where the expected cost would only be €160, making the bonus +EV.

Low-Wagering Bonus (Profitable)

A sportsbook offers a €20 free play bonus with only 10x wagering. Enter bonus €20, wagering 10x, and assume 97% RTP. Total wagering is €200, expected loss is only €6. Since the bonus value (€20) exceeds the expected cost (€6), this is a genuinely profitable offer with an expected profit of +€14. Low-wagering bonuses under 15x on high-RTP games are typically worth accepting.
