Win rate, ROI and profit per bet from your record.
How to Use This Calculator
- Punch in the total number of bets you’ve placed
- Punch in how many of those bets won
- Punch in the total amount you staked across every bet
- Punch in the total amount returned (winning-bet stakes included)
- Read off your win rate, net profit, ROI, and average profit per bet
Formula
Win Rate = (Wins / Total Bets) x 100
Net Profit = Total Returned - Total Staked
ROI = (Net Profit / Total Staked) x 100
Profit per Bet = Net Profit / Total Bets
Frequently Asked Questions
What counts as a strong win rate in sports betting?
It all hinges on your average odds. At -110, you have to clear roughly 52.4% just to break even. At +150 average odds, around 40% gets the job done. Bottom line: win rate by itself says nothing about profit — ROI is the real measuring stick.
What does ROI mean in betting?
Return on Investment (ROI) tracks your profit as a percentage of everything you’ve staked. Positive ROI means you’re in the green. Sharp, long-term bettors usually land somewhere in the 2-10% ROI range.
How many bets before the numbers actually mean something?
Plan on at least 500-1000 bets before the results carry statistical weight. Anything under 100 bets is mostly noise — variance runs the show and it won’t tell you a thing about real skill or edge.
How do I get better betting results?
Hunt positive expected value (+EV) bets, track your closing line value (CLV), pick a lane in specific sports or markets, run disciplined bankroll management, and keep dissecting your results to expose your strengths and weaknesses.
