Free bonus terms tool
Casino bonus wagering calculator
Turn a headline multiplier into the total credited wagering requirement and the contribution-adjusted bet volume still needed. Add the game RTP and average bet for a cautious long-run cost and bet-count estimate. Use current offer terms; this tool does not confirm eligibility or promise that a bonus can be completed.
What the terms require
(bonus) × multiplier = credited turnover. Remaining eligible bet volume = remaining credited turnover ÷ contribution rate. Expected cost estimate = eligible bet volume × (1 − RTP). Approximate bets = eligible bet volume ÷ average bet.
Read these terms before using the result
The number is only one part of an offer. Confirm eligibility, expiry, maximum bet, excluded games, contribution tables, verification and withdrawal conditions on the live promotion. The UK Gambling Commission's consumer guidance similarly stresses checking restrictions on bonus funds and bet size; rules and legal protections differ by jurisdiction.
- A completed progress counter does not guarantee account verification or withdrawal.
- RTP is a theoretical long-run average, not a prediction for your session.
- Do not increase stakes or session time just to finish a requirement.
- Use only an entertainment budget separated from bills, savings and borrowed money.
- Stop if the terms, contribution table or progress display is unclear.

Wagering calculator questions
How is a wagering requirement calculated?
Multiply the amount named in the offer terms by the wagering multiplier. The named amount may be the bonus alone or the deposit plus bonus, so the live terms control which base is correct.
What does game contribution change?
Contribution controls how much of each eligible bet counts toward the requirement. At 20% contribution, five units of eligible betting are needed to add one unit of credited wagering progress.
Does reaching the calculated amount guarantee a withdrawal?
No. Verification, expiry, maximum-bet rules, excluded games, withdrawal conditions and other live terms can still apply. The calculator is an educational estimate, not an account decision.
Does this calculator show a current Luckly.gg offer?
No. Enter only values visible in the current eligible account or promotion terms. The calculator does not claim that any bonus, multiplier, payment method or game is available on Luckly.gg.
Does RTP predict what I will win or lose?
No. RTP is a long-run theoretical average across many plays. A short session can differ substantially, so the expected-cost result is a statistical estimate rather than a forecast or guarantee.
