Understanding ROI
What is ROI?
Return on Investment shows how efficiently you're using your capital. It's expressed as a percentage and measures profitability relative to your initial investment.
Why is ROI important?
ROI allows you to compare betting performance independent of stake size. A £100 profit on £1000 (10% ROI) is better than £200 on £3000 (6.67% ROI).
Professional Standard
Professional bettors typically aim for 5-15% ROI. Anything above 20% is considered exceptional and difficult to sustain long-term.
