Bankroll calculator

See how long your budget is likely to last and the odds of losing it all — set a limit before you play.

Risk of ruin is the chance your bankroll hits zero before your planned spins; expected loss is the average cost of the session.

Setting a session budget

Decide what you can afford to lose, then check how many spins that buys at your chosen bet size.

Bet size and survival

Smaller bets relative to bankroll mean longer sessions and lower risk of ruin.

Worked example

A €100 bankroll at €1 a spin on a high-volatility slot typically lasts a couple of hundred spins, with a real chance of an early wipeout.
