Poker Session ROI Calculator
Measure the true return on investment for a poker session after accounting for buy-in, cash-out, travel costs, and your hourly opportunity cost. Use it after any live or online session to track real profitability.
About this calculator
Session ROI measures how efficiently your poker investment of time and money generates profit. The formula is: ROI = ((cashOut − buyIn − travelExpenses − (sessionLength × opportunityCost)) / buyIn) × 100. The numerator captures net profit after subtracting all real costs: what you cashed out minus what you put in, travel expenses, and the value of your time quantified as an hourly opportunity cost (e.g., what you could earn working instead). Dividing by the buy-in normalises the result as a percentage, making it comparable across sessions of different stakes. A positive ROI means the session was profitable even after all costs; a negative ROI reveals hidden losses even when cash-out exceeds buy-in.
How to use
You buy in for $200, cash out $310, spend $15 on parking, play for 4 hours, and value your time at $20/hour. Plug into the formula: ROI = ((310 − 200 − 15 − (4 × 20)) / 200) × 100 = ((310 − 200 − 15 − 80) / 200) × 100 = (15 / 200) × 100 = 7.5%. Despite winning $110 at the table, once travel and opportunity costs are included, your true ROI is only 7.5%. This shows why tracking all costs is essential for evaluating whether poker is a worthwhile pursuit versus your next-best use of time.
Frequently asked questions
Why should I include opportunity cost when calculating poker session ROI?
Opportunity cost represents the income or value you forgo by spending time playing poker instead of doing something else productive. If you could earn $25/hour working, a 5-hour session carries a $125 implicit cost even if you are not spending that money directly. Ignoring opportunity cost overstates your poker profitability and can lead to overestimating your win rate. For recreational players this may be fine, but serious players treating poker as income must factor in this cost to determine whether the game is genuinely +EV relative to alternatives.
How do travel expenses affect the true profitability of live poker sessions?
Travel expenses — fuel, parking, food, accommodation — directly reduce your net profit and are often underestimated. A player who wins $80 at a $1/$2 table but spent $30 on gas and $15 on food has only netted $35 before opportunity cost. For players who drive significant distances to card rooms, these costs can easily consume a mediocre winning session or turn a small loss into a sizeable one. Tracking these expenses session by session gives a realistic picture of your hourly earn rate at different venues or stake levels.
What is a good ROI percentage for a consistent poker player?
ROI benchmarks depend heavily on stakes, game format, and whether you count opportunity cost. In live cash games, a solid winning player might achieve a 20–50% ROI per session on average over a large sample, but variance means individual sessions swing widely. In tournaments, ROIs of 30–100%+ are possible for strong players, though sample sizes need to be large (hundreds of tournaments) to be meaningful. The more important metric for cash game players is hourly rate — ROI as a percentage matters most for tournament players comparing buy-in sizes and fields.
