The wagering calculator works out the terms of clearing a bookmaker's bonus. Enter the bonus amount, the wagering multiplier, the minimum odds and the bet size — the calculator will show the required turnover, the number of bets and the expected outcome of the rollover.
What is a wagering requirement at a bookmaker
A wager (wagering requirement) is a bonus rollover multiplier. The bookmaker credits bonus funds to your account, but you can only withdraw them after meeting the conditions: you must place bets totalling the bonus amount multiplied by the wager.
For example, a $5,000 bonus with a ×5 wager means you need to turn over $25,000. Each bet must also be placed at odds no lower than the minimum (usually 1.40–1.70).
Wagering calculation formula
Rollover amount:
Turnover = Bonus × Wager
Example: a $5,000 bonus with a ×5 wager → you need to stake $25,000
Let us look at an example. Fonbet credits a $10,000 bonus with a ×3 wager and minimum odds of 1.50. The rollover turnover: 10,000 × 3 = $30,000. If you bet $1,000 at odds of 1.80, you need 30 bets. With a 55% strike rate (typical for odds of 1.80), over 30 bets you get: 17 wins × $1,800 + 13 losses × $0 = $30,600. Minus the $30,000 turnover — a net profit of about $600 on top of the bonus.
Typical wagering requirements at bookmakers
At legal bookmakers, wagering requirements are usually softer than at casinos (×20–×50). Typical values:
- Fonbet — ×3–×5 wager on the sign-up bonus, min. odds 1.50
- Winline — ×3 wager, min. odds 1.50, 30 days to clear
- Liga Stavok — ×5 wager on the welcome bonus, min. odds 1.50
- Melbet — ×5 wager, min. odds 1.40, 30-day period
- BetCity — ×3 wager, min. odds 1.70
Note: free bets often carry no wagering requirement — the profit from a winning free bet is available for withdrawal straight away. The wager applies to cash bonuses (on deposit, for a series of bets). Before activating a bonus, check the terms in the promotion rules.
Bonus rollover strategy
Which odds to bet at while clearing a bonus
The lower the odds, the higher the strike rate — but the slower the turnover (more bets are needed). The higher the odds, the faster the turnover builds, but the more losses you take.
In practice, the optimal range is odds of 1.70–2.20. At odds of 1.80 the strike rate is around 55%, and each bet adds its stake to the turnover. At odds of 1.40 (the minimum at many bookmakers) the strike rate is around 70%, but you need about 30% more bets for the same turnover.
Rollover deadline: how to make it in time
Most bookmakers set a rollover deadline — from 7 to 30 days. With a $10,000 bonus, a ×5 wager and a 14-day deadline you need to turn over $50,000. That is 50 bets of $1,000, or 3–4 bets a day. Bet less often and you will not clear the bonus in time — and it will expire.
The calculator shows the number of bets needed for a full rollover — compare it with the time available to judge whether it is realistic.
In the long run, a low-multiplier wager (×3) lets you preserve your bankroll and come out in profit at a 55%+ win rate. With a high wager (×10+), variance increases and the probability of a full rollover drops — a losing streak on favourites at odds of 1.50 can wipe out the bonus before the conditions are met. Betting on underdogs while clearing a bonus is risky: a loss on a single bet eats up several wins. Track the bookmaker's line and commission — the margin affects the real strike rate.
