How much bankroll do you need for 50NL?
A solid winner (5bb/100) needs about $1,450 (29 buy-ins) to play 50NL with less than 5% risk of going broke over 100,000 hands. A modest winner (2bb/100) needs about $2,350 (47 buy-ins).
Solid winner (5 bb/100)
29 buy-ins of $50
Modest winner (2 bb/100)
47 buy-ins of $50
For less than 5% risk of ruin over 100,000 hands at 100 bb/100 standard deviation. The bankroll figures come from the same risk-of-ruin math as the calculator, and the downswings from its simulation.
50NL is where many players first treat poker as a serious side income, and it is the stake where the classic "20 to 30 buy-ins" advice starts to show its seams. The guideline really describes a solid winner: at 5bb/100 the simulator lands on 29 buy-ins. A 2bb/100 winner needs 47, so the classic advice leaves a modest winner short, because a thin win rate takes much longer to climb out of a downswing.
The honest downswing numbers matter more here than the headline requirement. A 5bb/100 winner's 95th percentile worst stretch at 50NL runs about $2,075 peak to trough, and a modest winner's about $2,745. If you have never watched four figures evaporate while playing well, the first time is a psychological event. Budget for it emotionally, not just financially.
Because your win rate moves the requirement this much, the cheapest bankroll insurance at 50NL is not a bigger deposit, it is a better red line. Two extra big blinds per hundred hands buys you more safety than a thousand dollars of cushion.

Frequently Asked Questions
Is $1,000 enough to play 50NL?
$1,000 is 20 buy-ins. That is short of the simulated safe threshold for a solid 5bb/100 winner ($1,450) and well short for a modest 2bb/100 winner ($2,350). Playable as a shot with a firm rule to drop to 25NL, not as a full bankroll.
How long can a downswing last at 50NL?
Our simulations put the 95th percentile downswing duration for a modest winner at most of a 100,000-hand year: tens of thousands of hands where your bankroll sits below its previous peak. Winning players routinely spend months under water. Duration, not depth, is what breaks most players.
When should I move up from 50NL to 100NL?
The common trigger is 30 buy-ins at 100NL, which is $3,000. The calculator above shows how many hands of grinding that takes at your win rate, and what your risk looks like if you take the shot earlier.
