Key facts
- Value = bonus minus the expected loss while you meet the wagering, capped at the max cashout if there is one.
- Expected loss = amount you must bet x (100% - RTP). A $10 bonus at 1x on a 96% RTP slot costs about $0.40 to clear.
- Game contribution matters: at 20% contribution you must bet five times as much.
- Read the withdrawal rule too. Some casinos make you deposit before you can withdraw winnings from bonus funds.

How to use the calculator
- Deposit: leave it at $0 for a no deposit bonus.
- Bonus amount: the dollar value of the bonus credit.
- Wagering multiplier: how many times the bonus must be bet, from the offer terms.
- Max cashout: the most you can withdraw from the bonus, if the terms set a cap. Leave 0 if there is none.
- Game RTP: the game's return to player, shown in its info screen. 96% is a common figure for slots, but check the game you will play.
- Game contribution: how much of each bet counts toward wagering on that game, from the terms.
The formula
The calculator works out four numbers:
| Step | Formula |
|---|---|
| Wagering requirement | bonus x multiplier |
| Bets you must place | wagering requirement / contribution |
| Expected loss while wagering | bets x (100% - RTP) |
| Value | bonus - expected loss, capped at the max cashout |
Worked example: a $10 bonus at 1x
Caesars Palace Online Casino offers new players a $10 no deposit bonus on select slot games with 1x wagering, according to its own promotion terms checked on October 26, 2026. Assume you play a slot with a 96% RTP that counts 100% toward wagering:
- You must bet $10 x 1 = $10.
- The expected loss on $10 of bets at 96% RTP is $10 x 4% = $0.40.
- The average value of the bonus is $10 - $0.40 = $9.60.
The terms add one condition the math cannot show: you must make at least one cash deposit before you can withdraw winnings from bonus funds. See the full breakdown on our Caesars Palace Online Casino no deposit bonus page.
Why higher wagering changes everything
The same formula shows why the multiplier matters more than the headline. A $10 bonus at 15x on a 96% RTP slot means $150 in bets and an expected loss of $6, so the average value drops to $4. At 30x, the expected loss is $12 and the average value is below zero: the offer costs more than it gives, before any cap.
What the calculator does not show
The result is a long-run average. It does not model:
- Variance: a single session can end at zero or well above the average.
- Max bet rules: a low cap per spin can make wagering slow or impossible within the time limit.
- Time limits: a 3 or 7 day window can expire before you finish.
- Withdrawal conditions: a required deposit or identity check before cashing out.

Frequently asked questions
How do you calculate the value of a no deposit bonus?
Multiply the bonus by the wagering multiplier to get the amount you must bet, divide by the game contribution, and multiply by the house edge (100% minus RTP) to get the expected loss. The value is the bonus minus that loss, capped at any max cashout.
What does 1x wagering mean on a no deposit bonus?
You must bet the bonus amount once before it turns into withdrawable cash. A $10 bonus at 1x means $10 in bets on eligible games.
Why does RTP matter for wagering?
RTP is the share of bets a game pays back on average. At 96% RTP, the average cost of betting $100 is $4, so higher RTP games clear wagering more cheaply.
Does the calculator include max bet limits and time limits?
No. Check those in the terms yourself: a short time limit or a low max bet can make an offer hard to clear even when the math looks good.
Is the result what I will actually win?
No. It is the long-run average. Any single session can end well above or below it.
