Difference between ROI, yield and profitability

In sports betting, there are three important metrics to measure your success.


Bankroll increase

How much your bankroll increased during a specific period. One month, one year or since the start.

ROI will typically increase over time, whereas yield will stay roughly the same.

Yield doesn’t change depending on bankroll.

Calculation: Total profit / Starting bankroll

Note: In RebelBetting, we show ROI for each individual arbitrage. In this context, ROI shows how much you will profit by betting on this arbitrage, compared to money invested (the total stake).


Return per dollar invested

How much you profit per dollar invested (staked).

This is your betting efficiency. Generally speaking, a good bettor will yield between 5 and 10 percent profit in the long run.

Yield will typically not increase over time, as ROI does.

Calculation: Total profit / Total staked (total turnover)


Profit compared to money lost

Your profitability will typically not change much over time, similar to yield.

Profitability doesn’t change depending on bankroll.

Calculation: Total profit / Total losses
