Bonuses

Betting bonuses: what each type is really worth

A betting bonus is worth less than the amount in the headline. Rollover, minimum odds and the bookmaker's margin all take a share, and a free bet only pays out the winnings.

This page compares the bonus types, shows how to work out what an offer leaves you with, and links to a page for each type. The Gambling Prevention Act 2026 replaced the Public Gambling Act 1867 and makes online gambling and online betting criminal offences in Bangladesh. A foreign licence held by a bookmaker, such as Curaçao, does not make betting legal here.

Short answer

Which betting bonus is best?

The one that leaves the most once the terms are met. A deposit bonus with a low rollover usually leaves the most; a free bet is simpler but only pays the winnings. At odds 3.00 a free bet is worth about 63% of its face value on average.

Free bet, odds 1.50 32% of the amount

Free bet, odds 3.00 63% of the amount

Margin, 3 legs 14.3% accumulator

Margin, 5 legs 22.6% accumulator

Bonus maths

How to value a free bet

Value ≈ amount × (odds − 1) ÷ odds

with margin: × (1 − margin)

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

Why the stake does not count

A normal ৳1,000 bet at odds 3.00 returns ৳3,000 if it wins, stake included. A free bet only pays the winnings, ৳2,000.

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

Value your free bet

Enter the amount and the odds to see the value in taka.

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 formula assumes the odds reflect the true chance minus the bookmaker's margin.

Comparison

The bonus types side by side

The terms decide the value more than the amount. A smaller bonus without rollover can be worth more than a larger one you must stake many times.

Bonus type	How it works	Requires	What you keep	What it means
Deposit bonus	The bookmaker adds money to your first deposit	Deposit and rollover	The bonus minus what the rollover costs	worth it when the rollover is low and the minimum odds are fair.
Free bet	A bet the bookmaker pays the stake for	Often a first bet or a deposit	63% of the amount at odds 3.00	easy to value, but the stake never comes back.
Cashback	A share of losses back over a period	Losing bets in the period	The refund, as cash or bonus money	check whether it is paid as cash or with a rollover.
No-rollover bonus	Winnings can be withdrawn at once	Usually a deposit	All the winnings	fewer terms to track, usually smaller amounts.
No-deposit bonus	A small bonus or free bet for signing up	Registration and verification	The winnings after the terms	low risk, but often a max win and a short expiry.
