You doubled your bankroll this month. Does that mean you are a pro?
Maybe. Or maybe you just got lucky.
To know the truth, you need to calculate your Yield.
ROI vs Yield
People confuse these terms constantly.
1. ROI (Return on Investment)
$$ ROI = \frac{\text{Total Profit}}{\text{Starting Bankroll}} \times 100 $$
- Start: 1000. Month End: 1500. Profit: 500.
- ROI = (500 / 1000) * 100 = 50%.
2. Yield (Return on Turnover)
Yield is harder to fake. It measures the efficiency of every Taka you bet.
$$ Yield = \frac{\text{Total Profit}}{\text{Total Staked}} \times 100 $$
- You bet 50,000 Taka in total volume (Turnover).
- Your Profit is 500.
- Yield = (500 / 50,000) * 100 = 1%.

Why Yield Matters
A high ROI is easy with a small sample size (luck).
A positive Yield over 1000 bets proves you have an Edge.
- If your Yield is -ve, you are losing to the bookie's margin.
- If your Yield is 0% to 2%, you are breaking even (good start).
- If your Yield is 5%+, you are elite.
Conclusion
Stop bragging about your "Big Win". Show me your Yield over 500 bets.
That number tells me if you are a gambler or an investor.
