How much bankroll do you need for 50NL?
A solid winner (5bb/100) needs about $800 (16 buy-ins) to play 50NL with less than 5% risk of going broke over 100,000 hands. A modest winner (2bb/100) needs about $1,550 (31 buy-ins).
Solid winner (5 bb/100)
16 buy-ins of $50
Modest winner (2 bb/100)
31 buy-ins of $50
For less than 5% risk of ruin over 100,000 hands at 75 bb/100 standard deviation. Numbers come from the same Monte Carlo engine as the calculator.
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 is really about modest winners: at 2bb/100 the simulator lands almost exactly on 31 buy-ins. Prove a 5bb/100 win rate and the requirement nearly halves, because a strong win rate pulls you out of downswings before they reach your last buy-in.
The honest downswing numbers matter more here than the headline requirement. A 5bb/100 winner's 95th percentile worst stretch at 50NL runs about $1,340 peak to trough, and a modest winner's about $1,950. 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. For a solid 5bb/100 winner that clears the simulated safe threshold of $800 comfortably. For a modest 2bb/100 winner the safe number is $1,550, so $1,000 is thin: playable, but a normal bad stretch will force you down to 25NL.
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 conservative 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.
