About this calculator
Tournament ROI measures how much profit you earn relative to the total amount invested in buy-ins. The core formula is: ROI (%) = ((totalWinnings − (buyIn × totalTournaments)) / (buyIn × totalTournaments)) × 100. For example, if you spent $1,000 in buy-ins and cashed $1,200, your ROI is 20%. A positive ROI over a large sample (200+ tournaments) suggests a genuine edge, since tournament results are high-variance and short samples can show extreme ROI purely from luck. This calculator reports ROI only; it does not take a duration or ITM input, so pair the result with your own hourly-rate and ITM tracking for the fuller picture (see the FAQ below).
How to use
Suppose you play 50 tournaments at a $100 buy-in and cash out $6,500 in total winnings. Total invested = $100 × 50 = $5,000. ROI = (($6,500 − $5,000) / $5,000) × 100 = 30%. Enter your buy-in amount, tournaments played, and total winnings, and the calculator returns your ROI instantly.
Frequently asked questions
What is a good ROI for poker tournaments?
A positive ROI of 10–30% is considered strong for regular low-to-mid stakes tournament players over a meaningful sample. Elite players in softer fields can sustain 50%+ ROI, but variance is high in tournaments. You need at least 200–500 tournaments before your ROI is statistically reliable. Short samples can show extreme positive or negative ROI purely due to luck.
How many tournaments do I need for my ROI to be meaningful?
Statistical significance in poker tournaments typically requires 500 to 1,000+ entries, especially in larger-field events where cashes are rare. With fewer than 200 tournaments, a single deep run can inflate your ROI dramatically. Tracking your ITM% alongside ROI helps identify whether wins are concentrated in a few outlier results. The larger your field sizes, the more samples you need.
Why is hourly rate more useful than ROI for comparing poker formats?
ROI measures return per dollar invested but ignores how long each tournament takes. A 15% ROI in a 1-hour turbo is far more profitable per hour than a 15% ROI in a 10-hour main event. Hourly rate normalizes profitability across formats, letting you compare turbos, MTTs, and live events on an equal footing. If your goal is to maximize income, hourly rate is the metric to optimize.
