Currency note for readers outside India: the ₹ figures above are the operator's published India-market values, not converted equivalents. Every worked example below uses a single currency per calculation and never mixes units inside one formula. Mixing currencies inside a rollover calculation is the most common way players misjudge a bonus.
Infographic: calculating the real cost of a bonus
(Deposit + Bonus) × Wagering Multiplier = Required Qualifying Turnover
Example A: £100 deposit + £100 bonus × 15 = £3,000 turnover
Example B: ₹10,000 deposit + ₹20,000 bonus × 15 = ₹4,50,000 turnover
The wagering multiplier applies to deposit and bonus combined, which is the structure that produces the largest turnover requirement.
To evaluate the mathematical cost of a welcome bonus, look at the turnover required before bonus funds convert to withdrawable cash:
$$\text{Total Required Wagering} = (\text{Deposit Amount} + \text{Bonus Amount}) \times \text{Wagering Multiplier}$$
Worked example (single currency, GBP). Deposit £100, receive a £100 match bonus (£200 starting balance), with 15× wagering on the combined sum. Qualifying bets required:
$$(£100 + £100) \times 15 = £3,000$$
Worked example (single currency, INR). A ₹10,000 deposit taking the 200% match to the ₹20,000 cap creates a ₹30,000 balance at 15×:
$$(₹10{,}000 + ₹20{,}000) \times 15 = ₹4{,}50{,}000$$
Only bets at minimum odds, typically 1.50 or higher, count toward that requirement. Void and cashed-out bets are excluded from rollover progress, and casino contribution weightings mean live dealer tables may add as little as 0 to 10% of stake. Now the practical part: at a realistic 5% sportsbook margin, generating £3,000 of turnover has an expected cost of roughly £150. That is more than the £100 bonus you were chasing. Worth sitting with for a moment.
Behavioural research confirms this arithmetic is rarely how inducements feel in the moment:
