How to Read Bonus Terms Before You Deposit

Every promotion has two numbers. The one in the advertisement is the amount. The one that decides its worth is the rollover, and it sits several clicks away in the terms.

A $100 bonus with a five-times rollover requires $500 of turnover before anything can be withdrawn. Running $500 through a book taking a five percent margin costs about $25 in expectation, so the offer is worth roughly $75 — if every qualifying bet is one that would have been placed anyway. If the rollover forces bets that would not have been placed, the value falls further, and it can go negative.

A $30 bonus at one-times rollover is worth close to $30. It is a better offer than the $100 one, and it looks smaller in every advertisement ever written.

The second thing to establish is what the bonus actually pays in, because the two behave very differently.

A cash bonus is money. Win with it and both the stake and the winnings are yours.

A bonus bet, free bet or bet credit returns only the winnings. Stake a $50 bonus bet at 2.00 and $50 comes back, not $100 — the stake is consumed. That makes a bonus bet worth substantially less than its face value, typically somewhere between half and three quarters depending on the odds it is placed at.

It also changes how it should be used. Because the stake is never at risk, expected value rises with the odds: the same bonus bet returns far more at 5.00 than at 1.50. The instinct to "make sure it wins" by placing it on a short favourite is precisely wrong, and it is the instinct the mechanism is designed to exploit.

Almost every rollover carries a minimum price, usually between 1.50 and 1.80. This exists to stop the requirement being cleared cheaply on near-certainties, and it is what makes the rollover cost real money.

The interaction matters. A five-times rollover at minimum odds of 1.20 could be cleared with modest risk. The same rollover at minimum odds of 1.80 forces genuine exposure across every qualifying bet, and the variance is what the operator is counting on.

Check whether cashed-out bets count toward the requirement. At most operators they do not, which turns an apparently sensible risk-management decision into a forfeited bonus.

Four are worth reading every time.

Excluded payment methods. E-wallets are excluded from welcome offers at every bookmaker reviewed on this site. A first deposit through Skrill, Neteller or usually PayPal qualifies for nothing.

Expiry. Bonus funds and bonus bets expire, commonly in seven to thirty days. An unused bonus is worth exactly zero, and the shorter windows are designed to force activity rather than reward it.

Maximum conversion. Some offers cap how much of a bonus can become withdrawable regardless of what is won with it. A $50 bonus with a $100 conversion cap cannot produce a $400 payout no matter how the bets land.

Withdrawal forfeiture. Requesting a withdrawal before the rollover completes usually removes the bonus and often removes winnings derived from it. This catches people who deposit, win early, and try to take the money out.

Before accepting any offer: find the rollover multiple. Find the minimum odds. Establish whether it pays in cash or bonus bets. Check the expiry window and whether the intended deposit method is eligible.

If those five answers cannot be found in the terms within two minutes, the offer is not worth the time — and an operator that makes them hard to find has told you something about how it will handle the rest of the relationship.

For most bettors, promotions are a small factor dressed up as a large one. A bookmaker's pricing decides returns over a season; a welcome bonus decides them for about a week.

The one situation where offers genuinely matter is the opening deposit, because it is claimed once and the cost of getting it wrong — funding through a wallet and forfeiting it — is immediate. After that, price beats promotions every time.
