Loss Calculator: What an Hour of Play Costs
Type the chance, the payout and the fee from a game’s own screen. The calculator prices a session before you play it: the average loss, the usual swing around that average and how often a session ends ahead.
What the calculator asks for
A round costs you in three ways, and the calculator needs all three: how often a result wins, what a win pays back, and any fee taken from the stake before the round is played. Type them from the game’s own rules or help screen. The calculator then prices the session you have in mind.
At the time of writing (8 October 2026), BDG Win’s home page shows eight category labels: Popular, Lottery, Slots, Sports, Casino, Rummy, Fishing and Original. Game rules need an account to read, and we open none to test, so we have seen none. That is why no BDG Win game is loaded here. The four choices in the menu are examples of rounds as they are often described, and nothing more.
From the game screen to the boxes
Game screens state the same facts in different words. This table shows where the common wordings go.
| The screen says | Type this |
|---|---|
| Pays 1.95× | Pays (× stake): 1.95 |
| Win ₹95 on a ₹100 bet | Pays (× stake): 1.95, because your stake comes back as well |
| Even money, or 1 to 1 | Pays (× stake): 2 |
| 4 to 1 | Pays (× stake): 5 |
| 4 of 10 numbers win | Chance (%): 40 |
| 2% service charge on each bet | Fee taken from each stake (%): 2 |
A few games print only a return-to-player figure, such as 96%. Read that as the game keeping the other 4% over a long run. The calculator has no box for a bare return, so build one: enter a single result whose chance times its payout is 0.96, for example 48% at 2× with no fee. The expected loss then comes out right. The swing and the chance of finishing ahead become a rough guide, because you cannot know how the game spreads its payouts.
One ₹3,000 session, four bet shapes
Every row is ₹50 a round for 60 rounds, so ₹3,000 staked, with a 2% fee on each stake. The rows are the four shapes in the calculator’s menu, and the page opens on the second.
| Shape (what pays) | House edge | Expected loss | Typical swing | Chance of finishing ahead |
|---|---|---|---|---|
| Two-way bet (pays 2×) | 2.0% | ₹60 | ± ₹380 | 45% |
| Colour bet in a ten-outcome round (4 in 10 pay 2×, 1 in 10 pays 1.5×) | 6.9% | ₹207 | ± ₹365 | 28% |
| Violet bet (2 in 10 pay 4.5×) | 11.8% | ₹354 | ± ₹683 | 31% |
| One-number bet (1 in 10 pays 9×) | 11.8% | ₹354 | ± ₹1,025 | 39% |
House edge is the share of every rupee played that the game does not give back over many rounds. Expected loss is that share of the ₹3,000. The swing is how far one session usually lands from that average.
A higher payout is not a lower price
Compare the last two rows. Violet and one-number bets cost the same on average, ₹354, yet 39% of one-number sessions end ahead against 31% of violet ones. A one-number win returns about ₹441 on a ₹50 stake after the fee, and one such round can make a whole session look good. It is still the dearest bet per rupee played: 11.8% kept, against 2.0% for the two-way bet.
Try it. Switch the menu from the colour bet to the one-number bet and two tiles rise together. The chance of finishing ahead goes from 28% to 39%, and the expected loss goes from ₹207 to ₹354.
Many more rounds pull the other way. For the colour bet at ₹50, ending ahead is 37% likely after 10 rounds, 15% after 200 and 1% after 1,000.
A list of winners is half the picture
The home page we saw also shows a winning-information feed and a “Today’s earnings chart”. Both are the platform’s own displays, and we neither check nor quote their amounts. A list of winners cannot show how many rounds each person played, or how many sessions ended lower. The games guide explains why a feed is not a list of odds.
What it cannot tell you
- It has no view inside any platform. A wrong figure typed in gives a wrong price out, and it cannot catch the slip.
- Three winning results is the most it holds. A result you do not list is treated as a loss, which can make a game look dearer than it is.
- Anything credited back to you, such as a bonus, refund or cashback, is outside its sums. The bonus calculator prices an offer on its own.
- Its chance of finishing ahead is counted exactly, by listing every way the wins and losses can fall. A long session on a bet with several different payouts is the exception: it is estimated, and marked ≈. For colour-and-number rounds the Wingo odds calculator also counts the chance exactly.
- It puts a price on a plan. It has no opinion on whether you should play.
To work back from the most you are willing to lose to a stake, use the session budget. The lottery guide turns a round clock into an hourly cost, and the tools page has the rest.
Common questions
Are BDG Win’s own odds built into this calculator?
No. At the time of writing (8 October 2026) a BDG Win game’s rules are shown only inside an account, and we open none to test, so there is nothing of theirs to load. The four menu choices are examples of rounds as they are often described. Type the chance, payout and fee from the game’s own screen to price that game.
What do I type when a game shows only a return-to-player percentage?
Take the return away from 100 per cent: a 96 per cent return means the game keeps 4 per cent. There is no box for a bare return, so enter one result whose chance times its payout is 0.96, for example 48% at 2× with no fee. The expected loss then comes out right. Treat the swing and the chance of finishing ahead as a rough guide.
How do I enter a payout that my screen shows as ₹95 on a ₹100 bet?
Put the stake back in. The box wants the total returned per ₹1 staked, so winning ₹95 on ₹100 means ₹195 comes back and you type 1.95. Even money is 2 and 4 to 1 is 5. If a screen already says the payout includes your stake, type the figure as it stands.
Is the expected loss what I will actually lose this hour?
Not usually. It is the centre of a spread, and real hours land on both sides of it. With the opening numbers the centre is ₹207 and the typical distance from it is about ₹365, so one hour can end ahead or can lose more than ₹207.
Why does a one-number bet end ahead more often if it costs more?
Because one large win can carry a whole session. At ₹50 for 60 rounds the one-number illustration finishes ahead in about 39% of sessions against 28% for the colour bet, yet it loses ₹354 on average against ₹207. Ending ahead often and costing little are different things.
How do I turn the length of a round into rounds per hour?
Divide 3,600 by the seconds in one round. That gives 120 for 30 seconds, 60 for a minute, 40 for 90 seconds and 20 for 3 minutes. Put the answer in Rounds per hour and the time you play in Hours played. The round length itself comes from your own game screen.
