Bankroll calculator:
your unit size in one tap.

A fixed percentage of your bankroll used as your standard stake — usually 1–3%. It keeps your sizing consistent so one bad night can't blow up your bankroll.

Conservative ≈1%, standard ≈2%, aggressive ≈3%. Smaller units survive losing runs; larger units grow faster but risk ruin.

No. Chasing losses by raising your stake is the fastest way to bust a bankroll. Keep flat-staking your unit and recalculate only when your bankroll changes meaningfully.

It multiplies your bankroll by your risk level. A $500 bankroll at 2% gives a $10 unit, so a normal bet is $10 and your biggest bet (5 units) is $50. When your bankroll moves, enter the new number and the unit moves with it.

Setting aside a fixed amount of money for betting, then staking the same small slice of it on every bet. It means a losing week costs you a few units, not the whole bankroll.

Most bettors stake 1% to 3% of their bankroll per bet. At 2%, it takes 50 straight losses at your normal stake to lose everything, which gives you room to ride out a bad run.
