Poker Bankroll Calculator
See how many buy-ins you have and your risk of ruin. Use it before you move up a stake, not during a hand.
When to use it
Use it when you choose a stake or rebuild after a downswing. It does not pick hands for you.
Worked example: 20–30 cash buy-ins
| Input | Value |
|---|---|
| Bankroll | 10,000 |
| Buy-in | 200 |
| Buy-ins | 50 |
50 buy-ins is above the 20–30 cash guideline, so risk of ruin is low if the win rate holds.
FAQ
How many buy-ins do I need for cash games?
A common range is 20–30 buy-ins. Bankroll 10,000 with a 200 buy-in is 50 buy-ins, so risk of ruin is already low.
What is risk of ruin?
The chance you lose the whole bankroll under your win-rate assumption. Too few buy-ins or an unstable win rate pushes it up fast.
Is the bankroll calculator free?
Yes. Enter bankroll, buy-in and win rate to see buy-in count and risk of ruin.
