Win/Loss Helper
Track how you're doing with win rate, ROI and profit per bet from your history.
How to Use This Calculator
- Start by typing in the total number of bets you’ve placed
- Next, add how many of those bets were winners
- Now enter the total amount you staked across all of your bets
- Then enter the total amount returned to you (this includes the stakes on the bets that won)
- That’s it — you’ll see 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 healthy win rate when you're betting on sports?
It really comes down to the average odds you’re taking. At -110 odds you’d need around 52.4% just to break even, but at +150 average odds you only need roughly 40%. Keep in mind that win rate on its own doesn’t tell you if you’re making money — ROI paints a clearer picture.
What does ROI mean in betting?
ROI, short for Return on Investment, shows your profit as a percentage of everything you’ve staked. If it’s positive, you’re in the green. Most professional bettors land somewhere around 2-10% ROI when you look at the long run.
How many bets should I track before the numbers really mean something?
As a rule of thumb, aim for at least 500-1000 bets before the results become statistically meaningful. Anything under about 100 bets is mostly swayed by variance, so it won’t reliably tell you much about your actual skill or edge.
What are some ways to get better results from my betting?
Lean into positive expected value (+EV) bets, keep an eye on your closing line value (CLV), pick a few sports or markets to specialize in, stick to disciplined bankroll management, and keep reviewing your results so you can spot what you’re doing well and where you can improve.
