Casino bonus and wagering calculator

Turn bonus terms into required betting turnover. Enter the wagering base, multiplier, game contribution, and RTP to calculate the requirement and estimate the cost of completing it.

How much of each bet counts.
Qualifying wagering already completed.
Calculate the theoretical value of free spins

Uses the game RTP entered above. If wagering applies to actual winnings, calculate that requirement from the amount credited after the spins.

Example calculation
Total required turnover
$3,000.00

The amount of bets required at the selected contribution rate.

Expected full wagering cost
$120.00
Simplified bonus value
−$20.00
Remaining turnover
$3,000.00
Remaining cost
$120.00

Edit the example values to make your own calculation.

$100 × 30 ÷ 100% = $3,000

Simplified bonus value uses the cost of completing the full requirement. It assumes a cashable bonus and completed wagering. Balance exhaustion, expiry, cashout caps, maximum bets, and noncashable balances require a different model.

How wagering is calculated

Qualifying wagering = the amount covered by the offer × the wagering multiplier. Actual required turnover = qualifying wagering ÷ the contribution rate expressed as a decimal.

A $100 bonus with a 30× bonus-only requirement needs $3,000 of qualifying wagering. At 100% contribution, that means $3,000 in bets. At 20% contribution, the same target requires $15,000 in bets.

If 30× applies to a $100 deposit plus a $100 bonus, the qualifying target is $6,000. Check the offer's wording before choosing the wagering base.

Remaining qualifying wagering is the target minus the amount already credited, with a minimum of zero. Enter credited progress as the qualifying amount recorded by the offer. Divide the remaining target by contribution to find the remaining actual turnover.

Understand simplified bonus value

Expected wagering cost = required turnover × (1 − RTP ÷ 100). For a $100 cashable bonus, $3,000 of required turnover, and 96% RTP, that cost is $120. Simplified bonus value is $100 − $120 = −$20.

Simplified bonus value subtracts the expected cost of the full requirement from the original bonus. Expected remaining wagering cost describes only the future play implied by your entered progress. It does not establish the cashout value of your current balance.

The calculation assumes the turnover is completed, the bonus can become cash, and the same RTP applies throughout. Running out of funds, maximum bets, expiry, restricted games, withdrawal caps, and conversion rules can change the outcome.

For a noncashable bonus or an offer with a withdrawal cap, the turnover figures remain useful, but the simplified value is incomplete. Exact cashout expected value and completion probability require the full payout distribution and the offer's balance rules.

Free spins

Theoretical gross return = spin count × value per spin × RTP ÷ 100. For 50 spins at $0.20 each and 96% RTP, the result is $9.60 before wagering conditions or withdrawal restrictions.

If wagering applies to the winnings from free spins, use the actual settled winnings when they are known. Using $9.60 before the spins are played creates a scenario; it does not predict the amount they will pay.

Common questions

What if the game contributes 0%?

It cannot advance an outstanding requirement. If the qualifying target is already satisfied, remaining turnover is zero.

Can a positive value guarantee a withdrawal?

A positive simplified value follows from the model's assumptions. The path of wins and losses and the offer's restrictions still affect the actual cashout.

Can I use terms from any named casino?

Enter the terms of the particular offer and game. A provider's name alone cannot supply the contribution rate, wagering base, or conversion rules.
