Put the conditions into numbers.
Two simple calculators for understanding the maths. They run in your browser and do not send your inputs to a server.
Wagering requirements
Enter hypothetical terms to see how much wagering would count towards a requirement. The calculation assumes a fixed contribution rate throughout; it does not model expiry, stake caps, excluded games or changes to a balance.
Qualifying wagering required$3,000.00
Nominal total stakes at this contribution$3,000.00
These are wagering amounts, not a required deposit or an estimate of losses.
Total stakes = qualifying wagering ÷ (contribution / 100)
Example: a $100 bonus at 30× bonus-only requires $3,000 qualifying wagering. At 20% contribution, nominal stakes become $15,000. For a $100 deposit plus $100 bonus at 30× on both, the qualifying requirement doubles to $6,000.
Theoretical RTP arithmetic
Turnover means the sum of stakes. The result is the mathematical expectation for the inputs, not a personal outcome or a bankroll forecast.
Theoretical return$960.00
Expected loss under this model$40.00
Actual returns can differ substantially. This does not predict your session.
Expected loss = turnover − theoretical return
Read the exclusions before doing the arithmetic
A correct multiplication can still describe the wrong offer if the input terms are incomplete. Write down the base, multiplier, eligible games and contribution first. Then check time limits, stake limits, withdrawal restrictions and whether any conditions change once a bonus is accepted.
A zero wagering multiplier does not by itself prove unrestricted withdrawal. A game's contribution is also not its RTP: one describes progress against an offer condition, the other a game's theoretical return.
