Betting ROI Calculator
Return on investment measures actual results, not a forecast - it's the single number that summarizes how a betting record has performed so far.
How it works
Total returned includes stake back on winning bets. A positive ROI means you've turned a profit relative to everything risked; a negative ROI means a net loss.
Worked example: Staked $500 total across a month, returned $560: ROI = ((560 - 500) / 500) x 100 = +12%.
FAQ
How many bets do I need before ROI is meaningful?
Betting has high variance - a meaningful read on skill typically needs hundreds of bets, not dozens. Short-term ROI can be dominated by luck in either direction.
Should I include voided or pushed bets?
Exclude them from both the staked and returned totals, since a push returns your stake with no profit or loss.
