In the world of sports betting, saying “I made $500” means nothing without context. Did you risk $1,000 to make that $500, or did you risk $50,000? To accurately measure your skill as a handicapper, you need to look at percentages, not just dollars.
However, general financial calculators are often confusing because they don’t distinguish between Yield (Profit relative to total turnover) and ROI (Profit relative to starting bankroll). Our Sports Betting ROI Calculator is built specifically for bettors. It allows you to calculate both metrics simultaneously and supports the “Units” system used by professional cappers to track performance across different bankroll sizes.

Yield CalcHow to Use the Calculator
This tool is designed to audit your betting history, whether it is for a day, a month, or a specific season. Here is how to interpret the data:
- Select Mode:
- Currency ($): Use this if you want to input your exact dollar amounts (e.g., “I bet $5,000 total”).
- Units (u): Use this if you track your bets in units (e.g., “I am up +12.5 units this month”).
- Input Financials:
- Starting Bankroll: Your total funds available for betting.
- Total Turnover (Staked): The sum of all bets placed (e.g., 50 bets at $10 each = $500 turnover).
- Total Returned: The total amount returned to your account (Stakes + Winnings).
- Analyze the Metrics:
- Yield: This is your edge. It tells you how much profit you make on every dollar wagered.
- Growth (ROI): This tells you how much your total bankroll has grown relative to where you started.
ROI vs. Yield: Understanding the Difference
The biggest confusion in betting analytics is the difference between these two terms. This calculator displays both to give you the full picture.
1. Yield (The Skill Metric)
Formula: (Net Profit / Total Turnover) × 100
Yield measures the efficiency of your betting strategy. It is not affected by your bankroll size or how often you bet. If you have a Yield of +5%, it means for every $100 you bet, you keep $5 in profit long-term. Professional bettors typically sustain a yield between 3% and 7%.
2. ROI / Growth (The Wealth Metric)
Formula: (Net Profit / Starting Bankroll) × 100
This measures how fast your account is growing. You can have a low Yield but a high ROI if you bet a high volume.
Example Scenario
You start with $1,000. Over a month, you place 100 bets of $50 each (Total Turnover: $5,000). You end up with $250 profit.
- Yield: 5.0% ($250 profit on $5,000 turnover). This indicates a solid edge.
- ROI (Growth): 25.0% ($250 profit on $1,000 bankroll). This indicates massive account growth.
Frequently Asked Questions (FAQ)
What is a “Unit” in betting?
A “Unit” is a standard measure of bet size, usually equal to 1% or 2% of your bankroll. It allows bettors to compare performance without revealing their wealth. If Bettor A wins $10,000 (betting big) and Bettor B wins $100 (betting small), they might both have won exactly +10 Units, meaning their skill level is identical.
What is a good Yield in sports betting?
Anything above 0% is good, as most bettors lose. A Yield of 3-5% over a large sample size (1,000+ bets) is considered professional. A Yield of 10%+ is usually unsustainable long-term unless you are betting on niche markets with low limits.
Why is my Yield lower than my ROI?
This is normal for active bettors. Because you “recycle” your bankroll (betting the same money over and over), your Total Turnover will eventually become much larger than your Starting Bankroll. Since Yield divides profit by that huge Turnover number, the percentage is naturally smaller than ROI.
