What a bonus is actually worth

A bonus is a loan against turnover, not free money

A deposit bonus is advertised as a number added to your balance. What the terms actually describe is an obligation: you must stake a multiple of something before any of it becomes withdrawable. That multiple is the wagering requirement, and until it is met the bonus is not yours — it is a conditional credit.

This distinction changes the arithmetic. A 100% match to 500 looks like 500 of value. If the wagering requirement is 40x the bonus, you must place 20,000 in qualifying bets before the bonus clears. The question is no longer how large the bonus is; it is whether the expected loss on 20,000 of turnover is smaller than the bonus. That is a question about the game, not the promotion.

The method below works through the four terms that decide the answer, in the order that matters. None of it requires trusting a review. Every figure is on the operator's own terms page, and the operator's live page is the only source that counts because terms change.

Step one: read the wagering multiple and what it multiplies

The first figure to find is the multiple. Common values run from 25x to 50x. The second, easily missed, is what the multiple applies to: the bonus alone, or the bonus plus the deposit.

Take a 200 bonus on a 200 deposit with 40x wagering. If the multiple applies to the bonus only, required turnover is 8,000. If it applies to bonus plus deposit, required turnover is 16,000 — double the work for the same headline offer. Two promotions with identical 100% matches can differ by a factor of two in real cost purely from this line.

Write both numbers down before comparing anything else. The multiple and its base are the two most consequential figures in the entire set of terms, and they are usually stated in the same sentence.

Step two: apply game weighting, which is where the multiple really lands

Wagering requirements rarely count every stake at full value. Most terms assign a weighting: slots at 100%, live dealer at 10% or less, and some games excluded entirely. A 40x requirement on slots becomes 400x on a game weighted at 10%, because only a tenth of each stake counts toward the target.

This is the step most readers skip, and it is the one that decides feasibility. A bonus that is reachable on a 96% return-to-player slot is unreachable if the only games you play are weighted at 10%. Check which game categories your play falls into and whether they are weighted, excluded, or capped.

A useful discipline: estimate the turnover your chosen game must actually see by dividing the required qualifying turnover by its weighting. That number, not the headline multiple, is the real bar.

Weighting also interacts with volatility. Even at full weight, a high-variance game can exhaust a balance before the turnover target is reached, while a low-variance game grinds toward the same target with smaller swings. The terms do not mention variance because it is a property of the game, not the promotion — but it decides whether a reachable requirement is survived in practice.

Two players can face the same 40x requirement, one completing it and one busting out, purely from game choice. Read the weighting table as a map of which games the offer was priced around, then decide whether that is a game you would play without the bonus.

Step three: check expiry against the turnover you can realistically reach

Bonus conditions carry a clock. Seven, fourteen and thirty days are common. The expiry converts the requirement from a total into a rate: required turnover divided by days available gives the daily staking the terms demand of you.

Put the expiry next to the weight-adjusted turnover from step two. A 16,000 requirement inside a seven-day window asks for roughly 2,300 of qualifying stakes per day. Inside thirty days the same requirement asks for roughly 530 per day. The same bonus is a different proposition in each window, and only the pairing of the two figures shows it.

If the daily rate is above what you would naturally stake, the bonus is not a slower version of a good deal — it is a deal you will almost certainly forfeit, taking any winnings tied to it with it.

Step four: respect the max-bet and game-exclusion rules that void bonuses

Most terms cap the stake allowed while a bonus is active. A typical cap is 5 per spin or per hand. Exceed it even once and the operator is usually entitled to void the bonus and any winnings derived from it.

This turns an ordinary play pattern into a forfeit trigger. A player who normally stakes 10 a spin and accepts a bonus capped at 5 has to change behaviour for the entire wagering period, or lose the bonus and everything won with it. The cap is not a footnote; it is a constraint on how you play for weeks.

The same section usually lists excluded games and excluded bet types. Reading it takes two minutes and prevents the single most common way a bonus is lost — not through bad luck on the reels, but through a stake size the terms forbid.

Putting the four steps together into one judgement

The four terms compose into a single sentence you can act on: this bonus requires X of qualifying turnover at Y weighting before Z date, and I must not stake more than W per bet while it is active. If every part of that sentence is reachable with your normal play, the bonus is worth taking. If any part is not, the headline figure is decoration.

Run the arithmetic once with conservative numbers — the lowest weighting that applies to you and the shortest expiry the terms allow — and once with optimistic ones. If the bonus only works under the optimistic reading, you have found the assumption the offer depends on, which is exactly the assumption to check on the operator's live page before depositing.

Notice what has not been used to reach that judgement: no star rating, no claim about payout speed, no assertion about how the games feel. The method relies only on the operator's own published numbers and your own staking habits. That is deliberate — it is the part of a bonus evaluation that does not decay when a promotion changes.

The next time an offer appears, run the four steps before depositing rather than after. The terms decide the value; the advertisement only decides the framing.
