Sign-up bonus: what a welcome offer leaves after the terms

A sign-up bonus is the offer a new customer gets, usually a match on the first deposit. The headline amount is the cap, not the value: the rollover decides how much is left.

Here we show how to work out what a welcome offer is worth and which terms to read before you deposit.

Short answer

Is a sign-up bonus worth taking?

It can be, if the rollover is low and the minimum odds are fair. Each round of rollover costs the bookmaker's margin, and accumulators cost more: three legs at 5% each carry a margin of about 14.3%.

Margin, 5 legs 22.6% accumulator

Bonus maths

When the welcome offer is a free bet

Value ≈ amount × (odds − 1) ÷ odds

with margin: × (1 − margin)

Example: 1,000 × 2.00 ÷ 3.00 × 0.95 = ৳633.3

The stake is not paid out

Some welcome offers are free bets rather than deposit matches. A ৳1,000 free bet at odds 3.00 pays ৳2,000 if it wins, without the stake.

What it means: at a 5% margin the chance is 31.7%, and 31.7% × ৳2,000 = ৳633.

Value a free bet offer

Enter the amount and the odds.

Free bet amount ৳1,000 Odds you bet at 3.00 The book's margin 5.0%

Win if it lands ৳2,000

Chance to win 31.7%

Value on average ৳633

Share of the amount 63%

A free bet of ৳1,000 at odds 3.00 is worth ৳633 on average. The stake does not come back, so only the win counts.

The terms

Seven terms that decide what a welcome offer is worth

Read the rollover first. It decides how much of the bonus is left more than any other term.

Term	What it means	What to look for
Rollover	How many times the bonus must be staked	Lower is better; 5x–15x is common for sports.
Minimum odds	The lowest odds that count towards rollover	1.50–2.00 is common; higher means more losing bets.
Expiry	Days to complete the rollover	Longer gives you room to bet at your own pace.
Singles or multiples	Whether singles count, or only accumulators	Accumulator-only rollover costs more in margin.
Max win	A cap on winnings from bonus money	Matters most if you bet at high odds.
Eligible markets	Sports and markets the bonus can be used on	Check that cricket markets are included.
Max stake	A cap on each bet while the bonus is active	Limits how fast you can complete the rollover.
