FAQs
What's the difference between ROI and yield in betting?
They're often used interchangeably at the whole-book level, both meaning profit divided by total amount staked. This tool reports the same figure for both since it only has totals to work with, not a per-bet breakdown.
How is "average odds" estimated here?
It assumes flat, equal staking across all bets (total stake ÷ total bets per wager) and backs out the average winning odds needed to produce your total return from your wins. If your stakes varied a lot bet-to-bet, treat this as a rough estimate rather than exact.
What does "break-even win rate" tell me?
It's the win percentage you'd need at your average odds just to break even (neither profit nor loss). Comparing it to your actual win rate shows how much margin for error you have.
