Poker Bankroll Calculator: Professional Money Management
Bankroll management is the foundation of sustainable poker success. Even skilled players can go broke without proper money management, while disciplined bankroll practices allow recreational players to enjoy the game responsibly for years. This free bankroll calculator helps you determine safe buy-in levels, calculate your risk of ruin, and make informed decisions about game selection based on sound mathematical principles.
Whether you're playing home games in Texas Hold'em, exploring Omaha, or considering tournament play, understanding how to size your bankroll protects you from the natural variance inherent in poker.

What Is Bankroll Management?
Bankroll management refers to the practice of maintaining sufficient funds to absorb the natural variance in poker while minimizing the risk of going broke. Unlike games of pure chance, poker involves significant skill - but even the best players experience extended losing streaks due to the inherent randomness of card distribution. According to PokerNews strategy guides, proper bankroll management is what separates professional players from talented amateurs who eventually go broke.
The concept originated from professional gambling and was formalized for poker by players and theorists like David Sklansky and Mason Malmuth. Their work, particularly in "Poker Essays" and discussions on the Two Plus Two poker forums, established the mathematical foundation for modern bankroll management strategies.
Understanding Variance in Poker
Variance describes how much results deviate from expected outcomes. In poker, even winning players can experience massive downswings lasting thousands of hands. A player winning at 5bb/100 (big blinds per 100 hands) with typical standard deviation of 80bb/100 can easily lose 30 buy-ins over 20,000 hands due purely to variance - even while playing perfectly.
This mathematical reality explains why bankroll requirements exist. Research published by poker mathematics experts, including work referenced by the Gambling Sites strategy section, demonstrates that insufficient bankrolls lead to "ruin" - going broke before long-term edge materializes - even for skilled players.
Risk of Ruin Explained
Risk of ruin (RoR) calculates the probability that you'll lose your entire bankroll before achieving your long-term expected results. Key factors affecting your risk of ruin include:
- Bankroll size: Larger bankrolls dramatically reduce risk of ruin. Moving from 20 to 40 buy-ins can reduce RoR from 15% to under 2%.
- Win rate: Higher edges reduce risk. A 5bb/100 winner needs fewer buy-ins than a 2bb/100 winner.
- Variance level: Higher-variance games (like tournaments or PLO) require larger bankrolls.
- Game type: Cash games are lower variance than tournaments, where most players lose each event.
Cash Game Bankroll Requirements
Cash games offer more predictable variance than tournaments, making bankroll requirements somewhat lower. The standard recommendation varies based on risk tolerance and whether poker is recreational or professional:
| Player Type | Buy-Ins Required | Risk of Ruin | Best For |
|---|---|---|---|
| Conservative | 40-50 buy-ins | <1% | Professionals, high-stakes |
| Moderate | 25-35 buy-ins | 2-5% | Serious recreational players |
| Aggressive | 15-20 buy-ins | 5-15% | Casual players, reloadable bankrolls |
These recommendations assume you're a winning player at your stake level. If you're still learning the fundamentals covered in our Texas Hold'em guide or studying hand rankings, consider maintaining even larger cushions while developing your skills.
Tournament Bankroll Requirements
Tournaments have significantly higher variance than cash games because the vast majority of participants lose in each event. Even the most skilled tournament players only cash in 15-20% of events, and first-place finishes are rare. This requires larger bankrolls relative to buy-in size.
| Tournament Type | Recommended Bankroll | Rationale |
|---|---|---|
| Single Table SNGs | 50-100 buy-ins | Moderate variance, predictable structures |
| Multi-Table Tournaments | 100-200 buy-ins | High variance, top-heavy payouts |
| Turbo/Hyper-Turbo | 150-300 buy-ins | Very high variance, reduced skill edge |
| Satellite Tournaments | 30-50 buy-ins | Flat payouts reduce variance |
Moving Up and Down in Stakes
Proper bankroll management includes guidelines for when to move to higher stakes and when to drop down during downswings. A common framework:
- Move up: When you have 30+ buy-ins for the next level AND have demonstrated a winning track record at your current stake.
- Move down: When your bankroll drops below 20 buy-ins for your current stake. Ego should never prevent dropping down to protect your roll.
- Shot-taking: Some players take occasional "shots" at higher stakes with 10-15 buy-ins, planning to move down immediately if unsuccessful.
The discipline to move down when necessary separates sustainable players from those who repeatedly go broke. Many excellent players have lost their entire bankrolls by stubbornly refusing to drop stakes during extended downswings.
How to Use This Calculator
This calculator offers three modes to help you manage your poker finances:
Cash Game Mode
Enter your total bankroll and the stakes you want to play. The calculator will determine whether you're properly rolled, suggest appropriate stakes for your bankroll, and show how many buy-ins you have at various levels.
Tournament Mode
Input your tournament bankroll, typical buy-in amount, and tournament type. The calculator adjusts requirements based on the variance profile of different tournament formats and your estimated ROI.
Risk Analysis Mode
For advanced users, enter your win rate and standard deviation (available from poker tracking software) to calculate precise risk of ruin percentages and see how variance affects your expected results over different sample sizes. This mode uses statistical models similar to those discussed in academic poker variance research.
Bankroll Management for Different Game Types
No-Limit Hold'em
The most popular format requires moderate bankroll management. Post-flop skill matters significantly, and standard deviation typically ranges from 60-100bb/100 hands. The guidelines in this calculator are calibrated primarily for NLHE cash games and tournaments.
Pot-Limit Omaha
PLO, covered in our Omaha guide, is significantly higher variance than Hold'em due to closer equities between hands. Add 50% to standard bankroll requirements (e.g., if you'd use 30 buy-ins for NLHE, use 45 for PLO).
Mixed Games
Games like HORSE or 8-Game mix different variants with varying skill edges and variance profiles. Use standard requirements but focus on games where you have demonstrable edges.
Common Bankroll Management Mistakes
- Playing stakes too high: The most common mistake. Playing $1/$2 with $500 gives you only 2.5 buy-ins - almost guaranteed to go broke.
- Not separating poker money: Your bankroll should be completely separate from living expenses. Never play with money you can't afford to lose.
- Ignoring win rate requirements: Larger bankrolls help, but if you're a losing player, no bankroll is sufficient long-term.
- Tilting through your roll: Emotional play after losses can burn through bankrolls faster than normal variance. Understanding concepts like expected value helps maintain perspective.
- Cashing out at the wrong times: Taking money out of a properly managed roll can leave you under-rolled for your stakes.
The Psychology of Bankroll Management
Beyond mathematics, proper bankroll management provides psychological benefits. When you know you're properly rolled for your stake, you can make decisions without financial pressure affecting your play. The fear of going broke leads to suboptimal decisions - playing too tight, avoiding marginal spots, or making poor fold equity decisions.
Conversely, being under-rolled creates stress that compounds during downswings. Each losing session feels catastrophic, leading to tilt and further losses. The mental game of poker is intimately connected to financial security at the table.
Frequently Asked Questions
How much money do I need to start playing poker?
For recreational play, you can start with whatever amount you're comfortable potentially losing entirely. For serious bankroll building, start at the lowest stakes available (often $0.01/$0.02 online) with 20-30 buy-ins ($40-60). Build from there through winning play rather than deposits.
Can I use my poker bankroll for living expenses?
For recreational players, absolutely not - your bankroll should be entertainment money. For professionals, this requires careful planning. Many pros keep 6-12 months of living expenses completely separate from their playing bankroll to avoid financial pressure affecting their play.
What's the difference between a bankroll and a stake?
Your bankroll is your total poker funds. Your stake is the level you're currently playing (e.g., $1/$2 NLHE). Proper bankroll management means maintaining enough total funds to sustain variance at your chosen stake level.
How do I track my bankroll?
Use poker tracking software (like PokerTracker or Hold'em Manager for online play) or maintain a simple spreadsheet for live play. Track every session, including date, stakes, hours played, and result. This data helps calculate your win rate and standard deviation for more precise bankroll analysis.
Should I follow different rules for live vs. online poker?
Live poker typically has lower variance due to fewer hands per hour and often softer competition. You can generally use slightly fewer buy-ins for live play (15-25 vs. 20-35 for online). However, live players should also consider the higher rake percentage at lower stakes.
