Bonus wagering calculator
A casino bonus is worth its size minus what it costs you to clear the wagering requirement. That cost depends on the game you play. Enter the terms of any bonus below and the calculator works out the turnover, the expected cost and what the bonus is worth on average.
Your bet size is above the maximum bet allowed while wagering. At most casinos a single bet over the limit voids the bonus and its winnings.
How the calculator works
Every bet you place loses, on average, the house edge of the game. A wagering requirement forces you to place a fixed amount of bets before the bonus can be withdrawn, so its average cost is simply the turnover multiplied by the house edge. The bonus is worth taking when it is larger than that cost.
- Bonus: your deposit times the match percentage, capped at the maximum bonus.
- Wagering target: the multiplier times the bonus, or times deposit plus bonus if the terms say so. Read this carefully: "30x deposit plus bonus" is twice the work of "30x bonus" on a 100% match.
- Bets you actually place: if a game counts only 50% towards wagering, you need to bet twice the target on it.
- Expected cost: those bets times the house edge.
- Average value: the bonus minus the expected cost, capped by any maximum cashout.
The break-even house edge is the highest edge at which the bonus still pays for itself. Any game with a lower edge makes the bonus worth taking on average; any game above it makes the bonus a cost.
What the average hides
This is an expected value, the result you would get averaged over many attempts. A single attempt can end very differently. Large wagering requirements on volatile games often bust: the balance hits zero before the target is reached, and the bonus is lost. Small, steady bets on low-edge games finish more often but take many more bets, which is why the time limit matters. If the number of bets per day looks unrealistic for how you play, the bonus is worth less to you than the calculator shows.
Reading real bonus terms
- Game weighting. Many casinos count slots at 100% and table games, live dealer or originals at 10–50%, or exclude them. Enter that figure in "Game counts towards wagering".
- Maximum bet. A cap on bet size while wagering is common. Breaking it once can void everything.
- Withdrawals during wagering. Some casinos block all withdrawals until the bonus is cleared or forfeited, including your own deposit. Lumenbet works this way.
- Maximum cashout. A low cap on winnings from a bonus can make a big match pointless.

FAQ
What is a good wagering requirement?
It depends on the game. On a 1% edge game a 30x requirement on the bonus costs 30% of the bonus on average; on a 4% slot it costs 120%, more than the bonus itself. Lower multipliers and games that count fully are what make a bonus good.
Does a higher match percentage mean a better bonus?
No. A 250% match with heavy wagering can be worth less than a 50% match with light wagering. Compare the average value, not the headline.
Can I lower the house edge to beat the bonus?
Choosing low-edge games that count fully towards wagering is the main legitimate lever. Betting patterns do not change the house edge.
Is the calculator's result guaranteed?
No. It is an average. Individual results vary widely, and gambling can be addictive; only play with money you can afford to lose.
