Bonus Calculator: What You Must Bet to Withdraw

What a turnover requirement is

Many bonuses come with a rule: bet a set amount before you can withdraw. That set amount is the turnover, also called the wagering requirement, rollover or playthrough. It is a multiple of a base amount:

• turnover = multiple × bonus, when the terms apply the multiple to the bonus alone
• turnover = multiple × (bonus + deposit), when they apply it to both

A 20× requirement on a ₹500 bonus with a ₹500 deposit comes to ₹10,000 on the first reading and ₹20,000 on the second. The wagering requirements page sets the two side by side.

The turnover is not what the bonus costs you. Most of that money comes back and is bet again. What you lose is the part the game keeps: the turnover times the house edge. That cost comes out of the bonus, and what is left is what the bonus is worth.

A worked example, line by line

The calculator above opens on this offer: a ₹500 bonus, a ₹500 deposit of your own, a 20× multiple on the bonus only, ₹10 a round. The game is the two-way illustration, with a 2.00% house edge, meaning the game keeps ₹2 of every ₹100 played on average. That game is an illustration of how such rounds are commonly described. It is not any platform’s rules, so swap in the odds from your own app.

1. Must stake: ₹10,000. 20 × ₹500.
2. Rounds: 1,000. ₹10,000 ÷ ₹10 a round. If a round takes a minute, that is 1,000 minutes of play.
3. Expected loss: ₹200. ₹10,000 × 2.00%. This is the average price of unlocking the bonus.
4. Bonus worth: ₹300. ₹500 − ₹200. A negative number here would mean unlocking costs more than the bonus pays.
5. Chance of finishing ahead: 83%. Of 100 runs of this plan, about 83 end with more than you started with, counting the bonus. The tool ignores running out of balance on the way. The sentence under the tiles also gives a typical swing, here ± ₹310.
6. Rough chance of running out: 1%. Your balance is ₹1,000, the deposit plus the bonus. In about 1 run in 100 it touches zero before the 1,000 rounds are done, and the bonus goes with it. Read this as a size of risk, not a promise.

Now change one thing. Pick the colour illustration under Game odds. The expected loss becomes ₹690, the bonus worth becomes −₹190, and the chance of finishing ahead drops to 26%. The offer did not change. The game under it did. Is a bonus worth it? tests this across five multiples and three games.

Fill it in from a real offer

Box	What to type	Where it comes from
Bonus (₹)	The amount credited	The offer’s terms
Your own deposit (₹)	What you put in yourself, or 0 for a no-deposit bonus	Your plan
Turnover multiple (×)	The number before the “×” in the wagering line	The offer’s terms
The multiple applies to	The bonus only, or bonus + deposit	The offer’s terms; the costliest line to misread
Average stake per round (₹)	What you really bet, within any maximum the terms set	You, and the terms
Game odds	A preset, or My own house edge in per cent	Your app’s rules for the game that counts

If your app states a house edge, or a return-to-player figure (the edge is then 100% minus that figure), pick My own house edge and type it in. The tool then assumes the swing of an even-money bet, so for long-shot bets its risk figures come out too low.

Terms the boxes cannot hold, such as how much each game counts, a maximum bet, a time limit or a withdrawal cap, are covered on the wagering requirements page.

Reading the answer

Start with what the bonus is worth. A positive number means the bonus beats its cost on average. A negative number means the opposite. Then check the two risk tiles: the chance of finishing ahead and the chance of running out first. A positive average with a high chance of running out still loses often.

Under the tiles the tool prints the same offer at 1×, 5×, 10×, 20×, 30× and 50×. Look there to see how quickly the worth falls as the multiple climbs.

The offers on the platform’s page

At the time of writing (8 October 2026), the platform’s page shows a “Mega Spin Event” banner reading “₹500 Bonus Awaits”, and prompts that say “Get ₹500” and “Get ₹28”. We do not know the terms behind any of them, and the ₹500 in this calculator is a round number, not that offer. Take the multiple, the base and the other terms from the offer itself. Bonus offers lists the questions to ask before you accept one.

What it cannot tell you

• It does not know any platform’s terms, and we cannot see inside any platform. The answer is only as true as the numbers you type.
• It cannot see a clause you did not enter, such as a time limit or a cap on withdrawals.
• Every figure is an average with a wide spread around it.
• A link in a chat that promises a huge bonus is a different problem. Run it through the link checker before you open it.
