How to Compare Casino Welcome Bonuses
Welcome bonuses are where casinos compete hardest, and the headline numbers keep getting bigger. But a larger bonus is not always a better one. A modest offer with fair terms often beats a huge package with heavy wagering.
This guide gives you a simple method to compare welcome offers side by side. To see the offers themselves, go to our welcome bonus offers.
Step 1: Decide How You Will Play
The best bonus depends on you:
Slots player, regular deposits – a deposit match with free spins usually suits you.
Table or live casino player – most bonuses barely count for these games; look for cashback or a low-wagering offer.
Small budget – a high percentage on a small deposit, or free spins.
Big deposits – check maximum bet rules and look at high roller offers.
Want to withdraw quickly – choose no-wagering offers, or skip the bonus.
Step 2: Calculate the Real Value
A quick way to compare offers is to estimate the average cost of clearing the bonus and subtract it from the bonus amount:
Value ≈ bonus − (wagering amount × house edge)
For slots with 96% RTP, the house edge is about 4%. Let’s compare two offers on a £100 deposit:
| Offer A | Offer B | |
|---|---|---|
| Headline | 200% up to £200 | 100% up to £100 |
| Bonus on £100 deposit | £200 | £100 |
| Wagering | 50x bonus = £10,000 | 10x bonus = £1,000 |
| Average cost (4%) | £400 | £40 |
| Rough value | −£200 | +£60 |
Offer A looks twice as big but is worth less than nothing on average. Offer B is the better deal. Real results vary a lot from session to session, but this method shows which offer gives you the better odds.
Step 3: Check the Deal-Breakers
Maximum bet – can you play at the stake you want?
Excluded games – are your favourite slots on the list?
Time limit – can you finish the wagering in time?
Maximum cashout – is there a cap on winnings?
Sticky or non-sticky – non-sticky lets you withdraw real-money wins before the bonus is used.
Payment method – some e-wallets are excluded from welcome offers.
Our guide to casino bonus terms explains each of these in detail.
Step 4: Look at the Whole Package
Many welcome offers are spread across several deposits. A “£1,000 package” may be split over three or four deposits with separate wagering for each. Count only the parts you will actually use, and check the time allowed between deposits. Read more about the second and third deposit bonuses.
Step 5: Judge the Casino, Not Just the Offer
A good bonus at a bad casino is a bad deal. Before you sign up, check the licence, withdrawal times, customer support and reviews from other players. Our casino reviews cover all of these, and our best UK casinos list shows sites with fair welcome offers.
And remember: a welcome bonus is a way to get more play from your first deposit – not a way to make money. Set your budget before you compare offers, not after.
