How Wagering Requirements Work

A wagering requirement, also called a playthrough or rollover, is the amount a player must bet before a bonus, and the winnings from it, can be withdrawn. It is written as a multiplier. A 30x requirement on a $200 bonus means $6,000 in qualifying bets, and the multiplier alone does not say whether it applies to the bonus only or to the deposit plus the bonus.

That detail changes the workload a great deal. So do the game contribution rates, which decide how much of each bet counts, and the time limit, which decides how long the player has. Two offers that both say 30x can be very different in practice.

This guide explains how a requirement is calculated, how contribution rates and time limits change it, how progress is tracked, and what its average cost looks like. A requirement is also a reminder that a bonus is not free money: clearing it means wagering on games where the house has an edge. Every offer used below is fictional and exists only to show the arithmetic. Terms vary between offers, products and states, so the offer’s own terms are what count.

What a Wagering Requirement Is and How It Works

When a casino credits a bonus, such as the one described in how a casino deposit match bonus works, it usually attaches a wagering requirement. The requirement is the casino’s condition for letting bonus funds, and winnings made with them, become withdrawable.

The requirement is built from two parts: a multiplier (the “x” in the terms) and a base. The base is the amount the multiplier is applied to. Some offers use the bonus only. Others use the deposit plus the bonus. A few apply it to winnings from free spins instead. The terms state which.

Wagering is counted by the amount bet, not by the amount won or lost. If a player bets $10 and loses, $10 usually still counts toward the requirement (if the game counts at all). Every qualifying bet moves the counter, and winnings played back through also count, which is why requirements are far larger than the bonus itself.

Most accounts show progress in a bonus section, listing the amount wagered and the amount remaining. A time limit usually runs alongside it. If the requirement is not met in time, the bonus and winnings from it are typically removed.

Some offers advertise “1x” or “no wagering.” A 1x requirement means the base is bet once. Even then, the other terms still apply, such as expiry dates, maximum bets and caps on what can be withdrawn.

Wagering Requirements Calculator: The Formula

Three formulas cover most situations. The first gives the required wagering.

where:

multiplier = the “x” in the terms; base = the bonus only (B), or the deposit plus the bonus (D + B), as the terms state.

The second gives the actual betting needed on a game that counts only part of each bet.

where:

remaining requirement = the wagering still to be counted; contribution rate = the share of each bet that counts, written as a decimal (10% = 0.10).

The third gives a rough expected cost, an average and not a prediction.

where:

total amount wagered = the actual bets placed; house edge = 100% − RTP, with RTP the game’s return to player.

Here is a quick use of the first two formulas. A $50 bonus at 25x on a bonus-only base needs 25 × $50 = $1,250 of wagering. On a game that counts 25%, the actual betting needed is $1,250 ÷ 0.25 = $5,000.

Because it uses an average, the expected cost says nothing certain about any one session. Real results swing above and below it, which is variance. The formulas also leave out time limits, maximum bets and cashout caps.

Worked Example: A Fictional 30x Offer

Example offer (fictional): Casino A offers a 100% deposit match up to $300 with a 30x requirement on the bonus only. A $200 deposit earns a $200 bonus. Slots count 100%, table games count 10%, and the time limit is 7 days. Assume a hypothetical slot with a 96% RTP, which is a 4% house edge.

Step 1. Required wagering = 30 × $200 = $6,000.

Step 2. On slots, actual bets needed = $6,000 ÷ 1.00 = $6,000. On table games, $6,000 ÷ 0.10 = $60,000.

Step 3. Pace over 7 days ≈ $6,000 ÷ 7 ≈ $857 a day.

Step 4. Expected cost on the slot ≈ $6,000 × 4% = $240.

Step 5. Simplified value ≈ $200 − $240 = −$40.

In words: on average, this offer costs more than it gives, about $240 in expected losses against a $200 bonus. That is a simplified estimate that ignores caps, maximum bets and variance. To see how progress is counted, suppose the player bets $2,000 on slots and $500 on table games. Counted wagering = $2,000 + ($500 × 0.10) = $2,050, so $6,000 − $2,050 = $3,950 remains.

Variations: Base, Multiplier and Contribution

The base and the multiplier together set the size of the requirement. The table shows the required wagering for a fictional $100 deposit with a $100 bonus. Changing the base from bonus only to deposit plus bonus doubles every figure.

Contribution rates then change the actual betting needed. With example terms of slots at 100%, table games at 10% and excluded games at 0%, a $3,000 requirement takes $3,000 on slots, $30,000 on table games, and can never be met on excluded games.

Other cases follow the same logic. Free spins winnings can carry their own requirement: $8 in winnings at 35x means 35 × $8 = $280 of wagering. A fictional 1x offer on a $200 bonus needs $200 in bets, and at a 4% house edge its expected cost is $200 × 4% = $8. Sportsbook offers often add a minimum odds rule for qualifying bets, and poker rooms usually release a bonus in steps rather than through a rollover.

Common Catches and Mistakes

Reading only the multiplier is the most common error. The same 30x is $6,000 or $12,000 on a $200 bonus and $200 deposit, depending on the base.

Ignoring contribution rates comes next. A game that counts 10% needs ten times the betting, and a game that counts 0% does nothing for the requirement.

Overlooking the time limit can end the bonus before the requirement is met, and the pace needed may be higher than expected.

Betting over the maximum bet while a bonus is active can void winnings under many terms.

Forgetting extra requirements on winnings can also matter. On some offers, winnings from free spins or from a bonus carry their own multiplier, which adds a second requirement.

Assuming wins reduce the requirement is a further mistake. Only qualifying bets count, whether they win or lose. Finally, a rollover is never a reason to bet more than planned: gambling is best treated as paid entertainment within a budget.

Checklist: Reading a Wagering Requirement

Before deciding anything, read the wagering section of the offer’s terms and check these points:

• The multiplier and the base (bonus only, or deposit plus bonus)
• The time limit, and the daily pace it implies
• Contribution rates by game, and excluded games
• The maximum bet while the bonus is active
• Whether winnings from the bonus or from free spins carry their own requirement
• Any maximum cashout cap or minimum odds rule
• How progress is displayed in the account
• Whether the requirement covers one bonus or several at once

To check the math, multiply the multiplier by the right base, divide by the contribution rate for the game, then multiply the amount wagered by the house edge to estimate the cost.

Related Concepts and Next Steps

A wagering requirement is one of several terms that decide what an offer is worth. Bonus terms such as expiry, maximum bets and cashout caps work alongside it, and bonus mathematics turns the requirement into an estimate of real value.

The same reading habits apply to free bets, sportsbook promotions and poker bonuses, though the rules differ for each. Wherever a requirement appears, look for the base, the multiplier, the contribution and the time limit, then work out what clearing it costs. Terms vary by offer, and the offer’s own terms are what count.

Because a rollover can tempt a player to bet more than planned, it helps to set a budget first and to treat gambling as paid entertainment, not as a way to earn the bonus.
