Deposit + bonus wagering calculator

“Deposit + bonus” (D+B) multiplies your own deposit alongside the bonus. On a 100% match, 10× (D+B) equals 20× the bonus (£1,000 in bets on a £50 bonus instead of £500), and 30× (D+B) equals 60× (£6,000 instead of £3,000).

Borderline, high risk

£50 bonus on a £50 deposit, with 10× wagering on deposit + bonus

Close to break-even. Most of the headline value is eaten by the playthrough.

The smaller the match percentage, the harsher D+B gets

On a 50% match (£100 deposit + £50 bonus), 10× D+B requires £1,500 in bets — that is 30× the £50 bonus, pushing a seemingly modest 10× headline right to the edge of negative EV.

Common questions

How do I convert D+B wagering to bonus-only?: Multiply the stated wagering by (deposit + bonus) ÷ bonus. For a 100% match, multiply by 2; for a 50% match, multiply by 3.
