Return on Investment

Synonims: ROI, Yield.
A measurement of efficiency of series of bets, expressed in percentage.
ROI = Sum of returns from all bets / Sum of stakes of all bets
Higher the ROI, bigger the profitability of betting. ROI below 100% indicates loss.

Yield basically has the same meaning, so these two terms are usually interchanged. Yield is displayed slightly different, as the profit on investment:
Yield = Sum of profits from all bets / Sum of stakes of all bets

Obviously, ROI - Yield = 100%.
Example: ROI of 112% corresponds to Yield of 12%, and ROI of 97% corresponds to Yield of -3%.
See: Strike Rate.
