How Wagering Requirements Actually Work
When an online casino offers you a welcome bonus or a reload promotion, there is almost always a catch attached — the wagering requirement (sometimes called a playthrough requirement). This is a multiplier that tells you how many times you must bet the bonus amount (or in some cases, the bonus plus your deposit) before you are allowed to withdraw any winnings generated from that bonus money.
For example, if you deposit K200 and the casino matches it 100%, you receive a K200 bonus. If the wagering requirement is 35×, and it applies to the bonus amount only, you must wager a total of K7,000 (K200 × 35) before withdrawing. If the requirement applies to the bonus plus the deposit, your total wagering climbs to K14,000 — a significant difference that players often miss when reading the fine print.
Game Contributions — The Hidden Variable
Not all games contribute equally to clearing your wagering requirement. Pokies typically contribute 100%, meaning every Kina you wager on pokies counts in full. Table games like blackjack or roulette often contribute only 10–20%, or sometimes zero. This is because table games have naturally lower house edges, meaning the casino earns less per hand. If you play a game with only 50% contribution, you effectively double the real amount you must spend to clear the bonus.
This calculator accounts for contribution percentage so you see the actual number of spins or hands you need to play, not just the theoretical figure quoted in the casino terms.
Expected Loss and Real Value
The most important number in any bonus analysis is the expected loss. This is calculated using the game's Return to Player (RTP) percentage. A game with 96% RTP has a 4% house edge. If you must wager K7,000 to clear a bonus, your statistically expected loss is K7,000 × 0.04 = K280. If the bonus itself is only K200, you are statistically losing K80 by claiming it — the bonus has negative real value.
That said, expected value is an average across millions of spins. In the short term, individual players can finish ahead or behind. The real value score simply tells you whether the mathematics favour the player or the house over the course of completing the requirements.
| Output | Formula |
|---|---|
| Bonus Amount | MIN(Deposit × Match%, Cap) |
| Total Wagering | Bonus × Wagering Multiplier |
| Adjusted Wagering | Total Wagering ÷ (Contribution% ÷ 100) |
| Estimated Spins | Adjusted Wagering ÷ Bet Size |
| Expected Loss | Adjusted Wagering × (1 − RTP ÷ 100) |
| Real Bonus Value | Bonus Amount − Expected Loss |
Why Bonus Value Score Matters
The Bonus Value Score (0–100) is our proprietary rating that weighs the expected loss against the bonus size, penalises excessive wagering requirements, and rewards higher RTP games. A score above 60 suggests a legitimately valuable offer. Scores above 75 are rare and indicate excellent bonus terms. Most casino bonuses score in the 25–55 range, which reflects the reality that casinos structure these offers to maintain a mathematical edge. Use the score to compare offers side by side rather than being swayed by headline deposit match percentages.
5 Tips to Clear Wagering Requirements Faster
-
1
Always Play the Highest RTP Pokies Available
Seek out pokies with 96–98% RTP rather than settling for whatever appears on the homepage. Every percentage point of RTP saved reduces your expected loss during wagering. Some casinos list RTP in the game info panel — check before you spin. Games by Pragmatic Play, NetEnt, and Microgaming regularly feature high-RTP titles above 96.5%.
-
2
Stick to 100% Contribution Games Only
Unless you fully understand the contribution percentages and have accounted for them in your calculations, avoid table games while clearing a wagering requirement. Playing blackjack at 10% contribution means you need ten times as many hands to clear the same bonus. This dramatically increases your exposure to variance and expected losses over the session.
-
3
Use a Consistent Medium Bet Size
Avoid very small bets — many casinos have minimum bet requirements during bonus play, and tiny bets can trigger terms that forfeit your bonus. Equally, avoid very large bets — these increase variance dramatically and can bust your balance before you clear the requirement. A consistent bet of 0.5–1% of the total wagering target per spin is a sensible approach that balances speed with risk management.
-
4
Read the Time Limit Fine Print
Almost all casino bonuses expire after a set number of days — typically 7 to 30 days. If you fail to complete the wagering requirement within that window, the bonus and any associated winnings are forfeited. Use this calculator to estimate the number of spins required, then divide that by your average session length to make sure the timeline is realistic before you claim.

5
Compare Bonuses Before Claiming — Use the Presets Above
A 200% bonus match sounds more attractive than a 100% match, but if it comes with a 60× wagering requirement instead of 30×, the real value can be significantly lower. Use the casino presets built into this calculator to compare apples to apples. The Bonus Value Score will quickly reveal which offer actually puts more money back in your pocket after clearing.
Frequently Asked Questions
A wagering requirement (also called a playthrough requirement) is the number of times you must bet your bonus — or bonus plus deposit — before you can withdraw winnings. For example, a 30× wagering requirement on a K100 bonus means you must wager K3,000 in total before cashing out. Always check whether it applies to bonus only or bonus plus deposit, as this dramatically changes the real cost.
Real bonus value is calculated by subtracting the expected loss from wagering from the nominal bonus amount. House edge equals 100% minus the game's RTP percentage. Expected loss = adjusted wagering required × (1 − RTP ÷ 100). If the expected loss exceeds the bonus amount, the bonus has negative real value, meaning you are statistically paying to use it rather than receiving a genuine benefit.
Game contribution is the percentage of each bet that counts toward clearing your wagering requirement. Pokies typically contribute 100%, while table games like blackjack may only contribute 10–20% or even 0%. If contribution is 50%, you need to wager double the nominal amount to clear the requirement. This calculator adjusts total wagering needed based on the contribution percentage you enter, giving you a true picture of the effort required.
A Bonus Value Score above 60 is considered good value for players. Scores of 75 and above are excellent and rare — they indicate that the expected loss is well below the bonus amount. Scores below 40 suggest the bonus offers poor value and the house edge during wagering will consume most or all of the bonus funds. Scores below 20 indicate the bonus is almost certainly a net cost to the player, not a benefit.
Yes, significantly. Higher RTP means a lower house edge, so you lose less money statistically while completing the wagering requirement. A game with 97% RTP has only a 3% house edge, while a game at 92% RTP has an 8% house edge — meaning you lose more than 2.5× as much money trying to clear the exact same bonus. Always prioritise high-RTP games when working through bonus wagering, and use this calculator to model the difference before you play.
