Frequently Asked Questions
What is ROI in sports betting?
ROI (Return on Investment) measures the percentage of profit or loss relative to your total amount staked. A positive ROI means you are profitable. For example, if you staked $1,000 and made $50 in profit, your ROI is 5%.
What are units in sports betting?
A unit is a standardized bet size used to track performance consistently regardless of bankroll. Typically 1 unit equals 1-5% of your bankroll. Using units lets you compare results with other bettors on a level playing field.
What is a good ROI for sports betting?
Even professional sports bettors typically achieve ROI between 2-10% over a large sample size. Anything above 5% over 1,000+ bets is considered excellent. Short-term ROI can be misleading — evaluate over at least 500 bets for a meaningful sample.
How is yield different from ROI?
In sports betting, yield and ROI are effectively the same metric — both measure net profit divided by total staked. Some bettors use "yield" to refer specifically to per-bet profitability, but the calculation is identical.
