Bonus mechanics without the brochure language
Headline bonus value is not the same as withdrawable value. Match percentage and wagering multiple get most of the attention; the clauses below decide what can leave the account. This page is the expanded limitations list for the bonus true-value calculator — each mechanic can only reduce or complicate that estimate. Pair it with the wagering requirement calculator for the playthrough total itself.
Why the brochure number is not what you can withdraw
An offer that says “100% up to 100 units” describes a starting credit, not cash you can withdraw on demand. Before withdrawal is allowed, published terms commonly layer a wagering requirement, game contribution weights, bet caps, time limits, and rules about which balance is withdrawable. The bonus true-value calculator models match, multiple, contribution, and RTP. Everything else on this page sits outside that model. If a clause applies, the calculator’s figure is an upper bound under your assumptions — not a prediction, and never a profit promise.
For how the multiple alone turns into a stake volume, start with what wagering requirements actually mean. For the weight that can multiply that volume, read game contribution rates.
Mechanic-by-mechanic reference
Each section states what the clause does, how it pushes withdrawable value down or makes it harder to realise, and what the calculator assumes when you leave it out. Where an offer states different wording, use the offer — this site does not publish operator terms.
Maximum cashout
Definition: a ceiling on how much you may withdraw from bonus-related winnings (sometimes stated as a multiple of the bonus, sometimes as a fixed amount).
Effect on value: truncates upside. A large win that would otherwise sit above the ceiling is cut back to the cap. That can only reduce what you take out relative to an uncapped reading of the same balance.
Calculator interaction: the true-value estimate does not apply a cashout cap. If the offer has one, treat the estimate as optimistic — the calculator assumes this does not apply.
Sticky vs withdrawable bonus
Definition: a sticky (non-withdrawable) bonus stays as bonus credit; wins may become cash under the offer’s rules, but the bonus line itself commonly does not convert to withdrawable funds. A withdrawable structure can convert cleared bonus funds into cash once wagering is met — still subject to every other clause.
Effect on value: sticky structures remove the bonus principal from what you can cash out. The brochure “bonus amount” is not a withdrawable asset in that case.
Calculator interaction: the estimate treats the bonus as value that can offset the expected cost of clearing. Under sticky terms that framing overstates what you can withdraw — adjust expectations downward. The calculator assumes this does not apply. Worked ceilings: max cashout and sticky bonuses.
Deposit-first (or bonus-first) release
Definition: rules that decide which balance is wagered or withdrawn first — for example, requiring the deposit to be played through before bonus funds unlock, or releasing cash and bonus in a fixed order.
Effect on value: complicates when money becomes available and can force more play than a simple “clear the multiple” reading suggests. Timing pressure rises even when the headline multiple looks unchanged.
Calculator interaction: the model has no release-order input. Sequence rules can only make the path to withdrawal longer or stricter than the estimate implies.
Win caps during clearing
Definition: a limit on how much you may win from a single bet, feature, or while the bonus is active — separate from a final max-cashout ceiling.
Effect on value: cuts large outcomes while you are still clearing. That reduces the chance that a short session finishes far above the long-run average the calculator describes.
Calculator interaction: expected-cost arithmetic assumes no per-win truncation. A win cap can only reduce realised upside relative to that average.
Payment-method exclusions
Definition: terms that exclude certain deposit or withdrawal methods from the bonus, change contribution, or void eligibility if a listed method is used.
Effect on value: can make the offer unusable for the method you already use, or change the effective cost after you have deposited. Either outcome complicates or reduces the value of accepting the bonus.
Calculator interaction: no payment-method field exists. If your method is excluded or reweighted, the estimate does not describe the offer you would actually play.
Bet-weight changes during clearing
Definition: contribution or eligible-game lists that change while wagering is active — for example, different weights after a feature unlock, or games that drop to zero contribution mid-clear.
Effect on value: raises effective turnover if you keep playing titles that suddenly count less. The stake volume needed grows; expected cost grows with it.
Calculator interaction: one contribution rate applies to the whole requirement. Mixed or changing weights need a range, not a single figure — see game contribution rates. The calculator assumes a single rate holds throughout.
Red-flag combinations
Clauses stack. A sticky bonus plus a low max cashout leaves little withdrawable upside even if you clear the multiple. Short expiry plus a tight max bet can make the required pace unrealistic for your limits. Payment exclusions plus deposit-first release can trap funds in a method you cannot use cleanly. None of these combinations is a reason to raise stakes — each is a reason to walk away or recalculate with harsher assumptions.
Run the playthrough total in the wagering requirement calculator, then the cost overlay in the bonus true-value calculator. Mentally subtract further for every clause above that appears in the offer.
How to read an offer in five minutes
- Match percentage and any maximum bonus — what credit you actually get.
- Multiple and whether it applies to bonus only or deposit plus bonus (wagering guide).
- Contribution table for the games you would play (contribution guide).
- Max bet and expiry — feasibility, not just headline cost.
- Sticky vs withdrawable, max cashout, win caps, payment exclusions, release order.
- Enter the arithmetic fields in the bonus true-value calculator, then lower the result for every clause the model ignores.
If a clause is missing or unclear, you do not have a complete picture. Do not fill gaps with guesses from other offers or this page.
A safer-play note
Understanding terms is not a strategy to extract value. A negative or heavily capped outlook is information to decline an offer, not a challenge to clear it faster. Set money and time limits before any deposit, never chase a remaining requirement after a loss, and stop when a limit is hit. Independent help resources are on the responsible gambling page. The sourcing contract for every calculator is on the methodology page. 18+ only.
Frequently asked questions
If the calculator shows a positive estimate, can I withdraw that amount?
No. The estimate subtracts only the long-run cost of required turnover under the RTP and contribution you typed. Caps, sticky rules, release order, and exclusions sit outside that model and can only reduce what you can take out.
Is a sticky bonus the same as a max cashout?
No. Sticky usually means the bonus balance itself never becomes withdrawable cash. A max cashout caps how much of your winnings you may withdraw. An offer can use one, both, or neither — read each clause separately.
Why does the calculator still ignore these clauses?
Because they are not arithmetic on match percentage, multiple, RTP, and contribution alone. Each clause needs its own numbers from the offer. The tool shows an upper-bound style estimate when those clauses are absent; when they are present, treat the result as optimistic.
Do payment-method exclusions change the wagering multiple?
Not always. Sometimes a method is simply ineligible for the bonus. Sometimes contribution or release rules change. Either way the headline match can look the same while the usable offer shrinks — check the payment section before depositing.
Where should I start if I only have five minutes?
Find the multiple and what it applies to, the contribution table, max bet, expiry, sticky status, and any cashout ceiling. Then run the bonus true-value calculator and lower your expectations for every clause the model does not include.
