The bonus is a sum, not a gift
Welcome bonuses all look equally good on the operator’s page. Whether an offer is actually worth anything is decided by three numbers: the wagering factor, the calculation base (bonus only, or bonus plus deposit) and the game weighting. The calculator above does exactly that sum — with the expected value of playing through, not with marketing promises.
In our reviews we document, for each operator, the real bonus terms as they stood at the time of testing, and whether the wagering was practically manageable in the test. The detail pages of this chapter compare the offer types: no-deposit bonuses, classic deposit bonuses, and the question of how to read wagering requirements before you accept them.
The four bonus types compared
Not every bonus works the same way. Four basic types appear in almost every casino, and they differ mainly in how hard the winnings are to cash out in the end.
| Bonus type | What it really is | Typical wagering |
|---|---|---|
| No-deposit | Starting credit or free spins just for registering | 40–60× |
| Deposit bonus | A percentage top-up on your first deposit | 30–45× |
| Free spins | Free rounds on selected slots | 30–40× on winnings |
| Cashback | A share of losses returned, often with no wagering | 0–10× |
How wagering requirements decide the value
The wagering factor states how often the bonus — sometimes bonus plus deposit — must be staked before a withdrawal is possible. An example: a €100 bonus at 35x wagering means €3,500 in stakes. At a slot return of 96%, playing that through costs around €140 in theoretical losses on average. So the bonus is only worth something if its benefit exceeds that cost — which is exactly the sum the calculator above runs.
The calculation base is decisive. If the factor applies to the bonus only, the requirement is half of what it is when calculated on bonus plus deposit. Two offers both labelled “35x” can therefore be worth very different amounts.
How to spot a fair bonus
A fair offer shows less in its size than in its fine print. A low wagering factor under 40x, a base calculated on the bonus alone, a realistic window of at least 30 days, a high game weighting for slots, and no cashout cap (or a generous one) are the features that actually make a bonus usable.
The most common traps
- Maximum cashout: No-deposit bonuses often cap the withdrawable win at €50 or €100, no matter how much you actually win.
- Game weighting: Table games frequently count only 10% or nothing toward wagering — clearing a bonus there barely moves the needle.
- Maximum bet: During wagering, the stake per round is usually capped at €5; a breach can cost the bonus and the winnings with it.
- Time window: Short seven-day windows make high wagering factors practically impossible to meet.
How to use the calculator
Enter your deposit, bonus amount, wagering factor and calculation base above. The calculator shows the total wagering required, the theoretical cost of playing through, and the residual value left in the bonus. That way you can see whether an offer is worth it before you deposit — instead of finding out at the cashout attempt.
Frequently asked questions
What does a no-deposit casino bonus mean?
Starting credit or free spins that the casino grants on registration, without any money being paid in. The catch almost always sits in the wagering requirements and the cashout caps — the bonus calculator factors both in.
How do wagering requirements work?
The bonus amount must be played through several times before winnings can be withdrawn — factors between 30x and 45x are common. If the factor applies to bonus plus deposit, the requirement effectively doubles.
Which bonus is actually worth it?
As a rule of thumb: the lower the wagering factor and the higher the game weighting, the more residual value remains. A 100% bonus at 35x on the bonus keeps roughly half its value on paper — a 45x factor on bonus and deposit almost always tips into the red.
