What Is ‘ROI’ in Betting?

ROI stands for Return on Investment and is a measure of profitability in sports betting. It is calculated by subtracting the total amount wagered from the total amount won, then dividing it by the total amount wagered. This number is then expressed as a percentage. ROI is used to measure the efficiency of a bettor, and the higher the ROI, the better the betting performance.

If a sports bettor has wagered $100 on a game and won $120, their ROI would be 20%. This means that the bettor has made a 20% return on their investment.
