What is ROI in betting?

ROI (Return on Investment) is the most important metric to measure the profitability of your bets. It shows the percentage of profit or loss relative to the total amount wagered. A positive ROI means you're making money; a negative ROI means you're losing.

ROI Formula

ROI = ((Total Returns - Total Wagered) / Total Wagered) × 100

Real Example

If you wagered €1,000 and got back €1,150, your ROI would be: ((1150-1000)/1000) × 100 = 15%. This means you earned 15% on your investment.

What is a good ROI?
