Your stake, calculated.
Not guessed.
Pick your game, enter your bankroll: the tool adapts the stake, loss limits, and simulation to the real math model of that game. And before any of that — set a budget your income can actually support.
Your profile
Three numbers are enough to calculate a coherent stake.
How do I estimate my edge?
A bookmaker's odds imply a probability: implied probability = 1 / odds. Your edge only exists if your own probability estimate for the event is higher than that implied probability — for example by comparing several bookmakers, or tracking form, injuries, head-to-head history, etc. Without that upstream analysis, there's no real edge: bookmaker odds already bake in their margin.
Recommended stake
Based on the chosen game's mathematical model.
Automatic stop-loss
Limits calculated from your bankroll and the chosen game's volatility — the moment a limit is hit, you stop playing. No negotiating.
Simulation Monte Carlo
1000 simulated sessions using the chosen game's model.
Except for sports betting (where a genuine positive edge is possible), all these games have a structurally negative expectation: the house wins on average, regardless of your betting system. These calculations are meant to slow down how fast you lose, not to turn a losing game into a winning one.

Your income and expenses
Your gambling budget should never dip into what pays your rent or bills.
Your disposable income
Each expense subtracted from income, down to a reasonable gambling budget.
This budget is a sensible estimate, not an absolute rule: it assumes a healthy leisure budget shouldn't exceed a small share of what's truly left over once necessities are covered. If you find yourself lowering your fixed expenses or savings just to free up more gambling budget, take that as a serious signal.
