Win probability is an assumption
A 52% estimate does not mean every 100 bets will land close to 52 wins. The simulator only reads the risk implied by the assumption you enter.
Free losing streak risk simulator: enter bankroll, stake size, win probability and planned bets to estimate streak chances, drawdown and variance pressure.

Losing streak simulator
Check the chance of a losing run first, then check whether the stake size would put too much pressure on your bankroll. A losing streak does not automatically mean the angle is wrong; oversized staking is the real problem.
Common scenarios
Start from an example, then edit the bankroll, stake and win probability to match your own plan.
Live simulation
Main readout
A losing run is possible, but it does not prove the bet selection is bad. Ask one practical question: after five straight losses, would you still follow the same plan?
Chance of 5 losses
48.81%
Stake as bankroll %
2%
5-loss drawdown
10%
Chance of 3 losses
97.31%
Chance of 10 losses
1.41%
Expected longest streak
4.75 bets
Bankroll after 5 losses
$9,000
Next step
If five losses would cut too deep, reduce stake size first. If the win probability may be wrong, check the price again with the EV calculator.
Important note
This tool estimates risk. It does not predict match results, casino outcomes or future profit. Real-money betting still depends on win-rate error, market movement, limits and discipline.
The streak is normal, but watch the stake
Chance of 5 losses: 48.81%
What it is for
Even positive-EV betting can go cold over a short sample. Use this simulator to see how often streaks can show up, then decide whether the stake size is sensible.
Quick answer
Method
The tool uses your estimated win probability and 1 to 1,000 planned fixed-stake bets to estimate the chance of at least one 3-, 5- or 10-loss run. It maps those streaks against stake size to show drawdown. The expected-longest calculation checks up to 40 consecutive losses; if meaningful tail risk remains beyond that point, the visible value is marked as a lower-bound estimate.
A 52% estimate does not mean every 100 bets will land close to 52 wins. The simulator only reads the risk implied by the assumption you enter.
A 20-bet run and a 100-bet run do not carry the same streak risk. The longer the sample, the more normal it becomes to see an ugly patch.
Five losses at 2% per bet is a 10% drawdown. Five losses at 10% per bet cuts the bankroll in half. The same streak can feel completely different depending on stake size.
Pre-bet check
Keep it practical: enter the bankroll you actually use, the fixed stake you plan to bet and a conservative win probability.
Reading variance
The result is not telling you whether the next bet wins. It helps you decide whether to continue, cut stake size or pause and re-check the edge.
Good betting positions can still lose in a bad order. Look at whether the original plan can survive the run before adding risk.
If a common losing run creates a drawdown you cannot tolerate, the problem is usually stake size, not the existence of a streak.
If the win probability feels shaky, go back to the EV calculator and check whether the price still has value before continuing.

Variance is easier to handle when the exit is written down first. Use the Profit and Stop-Loss Planner next to set a stop-loss, profit target and session limit.
