Definition
ROI (Return On Investment) is a key performance metric that measures how effectively your betting capital has grown. It compares your net profit to the total capital you invested (initial bankroll plus any top-ups), expressed as a percentage.
How It Works
Formula: ROI = (Net Profit / Capital Invested) x 100
ROI captures your entire betting activity: it measures how much your initial investment has grown. An ROI of 20% means you earned 20 cents for every dollar of capital invested. Unlike yield, ROI is tied to your bankroll size, not to the total amount wagered.
Example
- Capital invested (initial bankroll): $1,000
- After 6 months: current bankroll = $1,150
- Net profit: 1,150 - 1,000 = $150
- ROI = (150 / 1,000) x 100 = 15%
Why It Matters
ROI is the clearest measure of whether your bankroll is growing. An ROI above 10% over 500+ bets is excellent; between 0% and 10% is profitable; below 0% means your strategy needs adjustment. However, ROI can be misleading when comparing bettors with very different staking volumes. A bettor wagering $500 per bet and one wagering $10 per bet may have very different ROIs despite identical selection quality. For comparing skill, yield is the better metric.
