The Calculation Starts With Your Tracked Play, Not the Advertised Figure
A weekly bonus is rarely a random gift. The operator builds it from a record of what you wagered over the previous seven days, usually through a loyalty or promotional programme that logs every real-money spin and hand. The advertised number is the output of that record, not the starting point. So the first calculation to understand is the one the operator runs on your play before a bonus ever appears in your account.
That calculation is built from three inputs: your average bet size, the number of decisions or rounds you complete per hour, and the house edge on the games you played. Multiplied together, they produce a figure the industry calls theoretical loss. It is not money you necessarily lost. It is the expected cost of your action over time, and it is the number most loyalty and weekly-bonus schemes use to decide what you are worth to the venue.
Suppose, as an example, you play a game with a house edge of two per cent, averaging fifty units per round at sixty rounds an hour. The arithmetic is fifty times sixty times two per cent, which comes to sixty units of theoretical loss per hour. A venue that returns a small fraction of that as bonus credit is not being generous; it is pricing your play. The fraction it returns is printed in the programme terms, not in the promotion banner.
Why the Same Weekly Offer Produces Different Amounts for Different Players
Two players can receive the same promotional email and end up with different bonus amounts, because the calculation is personal. One player bets larger amounts, plays faster, or chooses games with a higher house edge. Their tracked theoretical loss is higher, so the weekly calculation credits them more. The other player bets smaller, plays slower, or sticks to lower-edge games, and the same percentage of a smaller number produces a smaller bonus.
This is why the phrase "weekly bonus" without a fixed amount attached is so common. The operator may state a percentage of tracked play, a tiered schedule, or a flat credit that resets each week, but the number that lands in your account depends on your own activity. The terms page for the promotion will state whether the bonus is a percentage of theoretical loss, a percentage of deposits, a fixed amount for reaching a play threshold, or some combination. Read that page before you assume the advertised example applies to you.
| Bonus structure | What the operator measures | What changes the amount |
|---|---|---|
| Percentage of theoretical loss | Your tracked wagers, game edge and speed | Bet size, decisions per hour, game choice |
| Percentage of deposits | Net deposits over the week | Deposit amount and timing |
| Fixed play threshold | Total wagered over the week | Whether you cross the threshold |
| Tiered loyalty credit | Points or status earned from tracked play | Accumulated points and current tier |
Reading the Terms That Decide What the Bonus Is Worth
Once the operator calculates your weekly bonus, a second layer of arithmetic decides whether any of it can become withdrawable cash. The most important number is the wagering requirement, sometimes called playthrough. Whether a withdrawal is permitted before you meet that wagering requirement turns on the operator’s terms and the regulator that enforces them, so check the current bonus conditions. The fact sheet for this article gives the arithmetic in its pure form: a requirement of thirty times on a bonus of fifty units means fifteen hundred units of wagering. That is the clean version. The real version is almost always messier.
Game weighting is the first complication. Not every game contributes equally to the wagering requirement. A slot might contribute fully, while a table game might contribute a small fraction, or nothing at all. If the terms say a table game counts at a reduced rate, then every unit you wager there moves you toward the requirement more slowly than a unit wagered on a slot. The weighting is stated in the bonus terms, usually as a percentage or a fraction per game category. Calculate your effective progress by multiplying your wager by the weighting factor for that game, not by assuming every wager counts equally.
Maximum-cashout caps are the second complication. A cap is the upper limit on what you may withdraw from winnings generated by the bonus, regardless of how much you win or how much you wager. A bonus with a low cap is worth less than the same bonus with a high cap, even if the wagering requirement is identical. The cap is stated in the terms, and it applies after the wagering requirement is met, not before.
Expiry windows are the third. A weekly bonus typically carries a deadline, often measured in days from crediting. If the wagering requirement is not completed inside that window, the bonus and any winnings attached to it are removed. The window is not a suggestion. It is part of the value calculation, because a requirement you cannot realistically complete in the time allowed is a requirement that will cost you the bonus.
What the Weekly Bonus Is Not Telling You
The promotional value is not the number in the subject line. It is the number that survives the wagering requirement, the game weighting, the cap and the clock. You can estimate that number before you opt in, but only if you read the terms and do the arithmetic yourself. Start with the bonus amount. Multiply it by the wagering requirement to get the total action you must produce. Adjust for the game weighting on the games you play. Then compare the cap to what a realistic session might produce, and check the expiry window against the pace at which you normally play.
None of this changes the house edge on the games themselves. A weekly bonus does not make a negative-expectation game positive. It changes the rate at which your bankroll is consumed, and sometimes it changes it in ways that are not obvious until you read the fine print. A bonus with a high wagering requirement, heavy table-game weighting and a short expiry window can be worth less than no bonus at all, because it encourages more play on terms that favour the operator.
Loyalty Programmes Use the Same Arithmetic, Spread Over a Longer Period
Weekly bonuses are often the visible tip of a loyalty programme that runs the same theoretical-loss calculation continuously. The programme tracks your average bet, your decisions per hour and the house edge of the games you play, and it converts that tracked value into points, tier progress or periodic credits. The weekly bonus is simply the programme paying out a slice of that value on a seven-day cycle.
Because the calculation is continuous, your game choice matters more than your session length. Two hours of high-edge play can generate more tracked value than four hours of low-edge play, and the loyalty system will reward the first player more. That is not a reason to choose high-edge games. It is a reason to understand that the loyalty value you receive is priced into the games you play, and that the operator has already accounted for it.
When you compare a weekly bonus to a loyalty credit, compare them on the same basis. What is the wagering requirement on each? What games count, and at what weighting? What is the cap, and when does each expire? A loyalty credit with no wagering requirement can be worth more than a larger weekly bonus with a heavy requirement, because the loyalty credit is closer to cash. The terms for each programme state these conditions, and they are not interchangeable.
FAQ
How do I find the exact formula for my weekly bonus?
The formula is in the promotion's terms and conditions, usually linked from the offer itself or from the promotions page of the operator's site. Look for the section that states whether the bonus is a percentage of tracked play, a percentage of deposits, or a fixed amount for crossing a play threshold. If the terms do not state the formula, contact the operator's support channel and ask for the written basis of the calculation before you opt in.
Does game weighting apply to the bonus amount or only to the wagering requirement?
Game weighting applies to the wagering requirement, not to the bonus amount itself. The bonus is credited at its stated value, but the speed at which you can clear it depends on the weighting of the games you play. A game that contributes at a reduced rate means you must wager more in total to satisfy the same requirement, so the effective cost of clearing the bonus is higher than the raw multiplier suggests.
Can a weekly bonus ever be worth more than the wagering requirement suggests?
Only in the sense that a low requirement, full game weighting, a high cap and a long expiry window leave more of the bonus intact. The wagering requirement is a cost, not a benefit. The value of the bonus is what remains after the requirement is met, the cap is applied and the window is respected. A bonus with a modest requirement and full slot weighting can leave more withdrawable value than a larger bonus with a punitive requirement and heavy weighting.
