OK Win Bonus Calculator: Turnover in Rupees

Updated 8 October 2026 · 4 minute read

Type the bonus, the multiple and what it applies to, and the calculator gives the rupees you must stake, the average cost of staking them and what the bonus is worth after that cost. Read the terms on your own screen first. We could not read any.

₹1,000you must stake before you can withdraw

100rounds at ₹10 a round

₹20expected loss while you do it

₹80what the bonus is worth after that cost

79%chance you finish with more than you started (ignores running out)

37%rough chance your balance hits zero first

On average, betting through ₹1,000 costs about ₹20, which leaves the ₹100 bonus worth about ₹80. That is an average: the swing is about ± ₹98, and the chance of running out of balance first is not small if it shows above zero. At these odds the bonus stops paying for itself above about 50×.

The same offer at other multiples (₹100 bonus, ₹10 a round)
Multiple	Must stake	Expected cost	Bonus worth
1×	₹100	₹2	₹98
5×	₹500	₹10	₹90
10×	₹1,000	₹20	₹80
20×	₹2,000	₹40	₹60
30×	₹3,000	₹60	₹40
50×	₹5,000	₹100	₹0

Chances use a normal approximation and treat the balance as a continuous walk, so read them as sizes of risk, not exact percentages.

A bonus is only worth what is left after the cost of staking its turnover. This calculator does that sum for the offer you type in. It runs in your browser, and the rest of the tools are listed on the index.

Which screen is the offer on?

At the time of writing (8 October 2026), the Activity tab was open to us without logging in. We opened none of the offers on it, so we read no amount, no multiple and no terms.

On the Activity tab	What the page showed	Can you price it?
First gift	A label under “Activity Award”	Only once its terms name a multiple
Gifts	“Enter the redemption code to receive gift rewards”	The same: the caption names no term
Attendance bonus	“The more consecutive days you sign in, the higher the reward will be.”	No multiple in that wording
Banners titled New Member Gift Package, Member First Deposit Bonus and Cumulative 10Days Recharge Bonus	Titles only	After you read the terms on your own screen

Find the offer on your own screen and read its terms there. A figure from a chat or a stranger’s screenshot is an advert and not the terms. The link guide explains why OK Win’s address changes between visits.

Three numbers to find in the terms

The bonus, in rupees.
The multiple, such as “10 times”.
What it applies to: the bonus alone, or the bonus plus your deposit.

Then add your usual stake and the game’s odds. If one of the three is missing, you cannot price the offer yet.

The ₹100 example

The tool opens on a made-up offer: a ₹100 bonus, no deposit, 10 times on the bonus, ₹10 a round, on its two-way illustration. Turnover comes to ₹1,000, which is 100 rounds. Staking it costs ₹20 on average, so the bonus is worth ₹80.

Multiple	Must stake	Cost, two-way	Worth	Cost, colour bet	Worth
1×	₹100	₹2	₹98	₹7	₹93
5×	₹500	₹10	₹90	₹34	₹66
10×	₹1,000	₹20	₹80	₹69	₹31
20×	₹2,000	₹40	₹60	₹138	-₹38
30×	₹3,000	₹60	₹40	₹207	-₹107
50×	₹5,000	₹100	₹0	₹345	-₹245

On the two-way illustration the bonus stops paying for itself above about 50 times. On the colour bet it does so above about 14.5 times.

When the multiple covers your deposit too

Take a made-up ₹500 bonus on a ₹500 deposit, 10 times, ₹10 a round, two-way. If the multiple applies to the bonus alone, you stake ₹5,000 over 500 rounds at an average cost of ₹100, and the bonus is worth ₹400. If it applies to bonus plus deposit, you stake ₹10,000 over 1,000 rounds at a cost of ₹200, and the bonus is worth ₹300. The break-even multiple falls from about 50 to about 25. A banner titled Member First Deposit Bonus tells you nothing about which base it uses.

What an average hides

The ₹80 is an average. The swing over those 100 rounds is about ₹98 either side. With no deposit, your whole balance is the bonus, so the tool puts the rough chance of hitting zero before the turnover is done at 37% on the two-way illustration and 54% on the colour bet. Those are rough, because the tool treats the run as continuous.

What this calculator cannot do

It cannot read an offer for you, and we could not read OK Win’s. It cannot say how a platform counts a stake or when a bonus can be withdrawn. Read those lines on the offer’s own screen. The rebate calculator prices offers that pay back a share of your play, and the help guide covers money questions.

Terms first, then the sum. The button opens OK Win’s page in a new tab; read its address bar before you type or tick anything.

Common questions

What is turnover, and why would a ₹100 bonus ask for ₹1,000 of it?

Turnover is the total of your stakes, added up round by round. A multiple of 10 on a ₹100 bonus means ₹1,000 must be staked before the bonus can be withdrawn, which is 100 rounds at ₹10. Whether a stake counts when it loses is a term to read on the offer’s own screen. We read none.

Does the Attendance bonus have a turnover term?

Not in what we read. At the time of writing (8 October 2026), the Activity tab described it only as “The more consecutive days you sign in, the higher the reward will be.” We opened nothing behind it, so we saw no multiple and no amount. There is nothing for the calculator to price until you have read the terms.

The terms just say wager 10 times. Which base do I choose?

Try both. “On the bonus alone” multiplies the bonus, and “on bonus plus deposit” multiplies the two together. With a ₹500 bonus and a ₹500 deposit at 10 times, the first needs ₹5,000 staked and the second ₹10,000. If the terms do not say which, that gap is the question to answer before you accept.

Why does the same bonus cost more on a colour bet than on a two-way bet?

Because the tool’s two illustrations keep different shares of each stake. The two-way bet keeps 2.00% and the colour bet keeps 6.90%. On ₹1,000 of turnover that is ₹20 against ₹69. These are the tool’s illustrations, not OK Win’s rules, which we could not read.

The tool says my bonus is worth ₹80. Will I finish ₹80 ahead?

No. ₹80 is an average over many tries. A single run swings about ₹98 either side of it, and with a no-deposit bonus your whole balance is the bonus, so the tool puts the rough chance of running out before the turnover is done at 37%. Some runs end with nothing.

A banner shows an amount but no multiple. What do I type?

Leave it until you have found the multiple. The multiples table shows how much the answer moves: the same ₹100 bonus is worth ₹98 at 1 times and nothing at 50 times on the two-way illustration. A banner’s wording is the page’s own, and we could not read the terms behind any of them.
