ROI & Performance Calculation – How We Measure Betting Success

We measure performance with three core metrics: ROI, Yield, and Units. These are the industry‑standard, transparent, and objective ways to evaluate betting success – far more meaningful than simple profit or win count. Furthermore, these metrics allow you to compare performance across different tipsters, bankrolls, and time periods with complete confidence.

In addition, we believe that transparency starts with how we measure success. Consequently, every single bet we place is tracked using these metrics, and the results are publicly available in our Historical Record Policy. For example, you can see our ROI across different leagues and markets, giving you a complete picture of our performance.

However, many beginners focus on simple profit or win rate – both of which can be misleading. A tipster can show large profit but have a tiny ROI if they risked huge amounts. Therefore, we always emphasise ROI as the primary metric. Furthermore, we encourage all bettors to track their own ROI to evaluate their performance objectively.

ROI (Return on Investment) – The Most Important Metric

ROI is the ratio of net profit to total staked, expressed as a percentage. It tells you how much you earn per unit of risk. For example, if you stake €1,000 and make a net profit of €100, your ROI is 10%. This means you earn €0.10 for every €1 you risk.

Formula: ROI = (Net Profit / Total Staked) × 100

ROI is the single most important metric because it standardises performance – you can compare results regardless of bankroll size. Furthermore, it accounts for both winning and losing bets, giving a complete picture of efficiency.

In contrast, simple profit (e.g., "I made €500") tells you nothing about how much was risked. A bettor who stakes €10,000 to make €500 has a 5% ROI, while another who stakes €1,000 to make €500 has a 50% ROI. The second bettor is far more efficient. Consequently, ROI allows you to make meaningful comparisons.

What is a good ROI? Any positive ROI is good, but professional bettors typically aim for 5‑15% over large samples. An ROI above 20% is exceptional and often unsustainable long‑term. However, always consider the sample size – a 20% ROI over 50 bets is less meaningful than 10% over 1,000 bets.

Yield – A Closely Related Metric

Yield is used interchangeably with ROI in most betting communities. Some define it as profit divided by total staked (same as ROI). Others define it per unit. We use ROI as our primary metric for consistency and clarity.

When you see a tipster claiming "Yield 12%", it means for every €1 staked, they make €0.12 profit on average. In addition, yield is often used in betting exchanges and tipster tracking platforms, making it a useful metric for comparison.

For example, if a tipster has a yield of 8% over 500 bets, that is a strong indicator of genuine edge. However, if the same tipster has a yield of 8% over only 50 bets, the result is less reliable due to variance. Therefore, we always emphasise the importance of sample size when evaluating yield.

Units – Standardising Performance Across Bankrolls

Units are a standardised measure of stake size. We define 1 unit as 1% of the bankroll. This allows our performance to be scaled to any bankroll – whether you have €100 or €10,000 to stake.

Why units matter: They show the relative performance without revealing absolute monetary amounts, which can be misleading. For example, a tipster who makes €1,000 profit might have staked €10,000 (10% ROI) or €100,000 (1% ROI). Units clarify this by showing performance relative to bankroll.

In addition, units allow you to adjust stakes based on your own bankroll. If we recommend a 1‑unit bet, you can stake 1% of your bankroll, whatever that amount is. Consequently, our approach is accessible to bettors of all bankroll sizes.

Furthermore, tracking performance in units helps you focus on the process rather than monetary outcomes. For instance, a losing streak in terms of units is less emotionally charged than a losing streak in terms of euros.

How We Apply These Metrics

• We calculate ROI over every single bet – no cherry‑picking. Our Historical Record Policy provides complete transparency.
• We show running totals so you can see performance over time and identify trends.
• We break down ROI by league, market, and time period – so you can see where we perform best. This is particularly important for understanding league performance differences.
• We track units consistently – 1 unit always equals 1% of the starting bankroll.

In addition, we publish our ROI and yield metrics in real time, updated after every bet. This means you always have access to the latest performance data. Consequently, you can make informed decisions about following our approach.

See our Historical Record Policy for how we maintain this data, and Why Results Vary for why short‑term ROI can be misleading.

ROI vs Win Rate – Why ROI Matters More

Win rate (strike rate) is the percentage of bets you win. However, win rate does not account for odds. For example, a bettor with a 60% win rate at odds of 1.50 has a negative ROI, while a bettor with a 40% win rate at odds of 3.00 has a positive ROI. Consequently, win rate alone is a poor indicator of success.

In contrast, ROI accounts for both win rate and odds, giving a complete picture of profitability. Therefore, we always focus on ROI rather than win rate. Furthermore, we encourage all bettors to track their ROI rather than just their win rate.

What Is a Good ROI? – Interpreting Performance

Interpreting ROI requires context. Here is a general framework:

• Below 0%: Losing strategy. You are losing money in the long run.
• 0‑5%: Marginal profitability. You may be breaking even or slightly profitable, but variance is still a significant factor.
• 5‑10%: Solid profitability. This is the range most professional bettors aim for.
• 10‑15%: Excellent profitability. This is sustainable for elite bettors.
• Above 15%: Exceptional. This is rare and often unsustainable over very large samples.

However, always consider the sample size. A 15% ROI over 100 bets is less meaningful than a 10% ROI over 1,000 bets. In addition, different markets have different expected ROI – for example, Asian Handicap markets may offer higher ROI than Correct Score markets due to lower margins.

How ROI Varies Across Markets and Leagues

ROI is not uniform across all markets and leagues. For example, in highly efficient markets like the Premier League, ROI may be lower due to sharp odds. In contrast, in smaller leagues like the Eredivisie or Eliteserien, ROI may be higher due to market inefficiencies.

Furthermore, different markets have different margins. Over/Under markets may have different ROI characteristics than BTTS or Asian Handicap markets. Consequently, we break down our ROI by league and market in our historical record, allowing you to see where we perform best.

How We Maintain Performance Data

Our performance data is maintained with complete transparency and accuracy. For example, every bet is recorded with the following details:

• Date and time of the bet.
• Sport, event, and selection.
• Odds taken – and verified against available odds at the time.
• Stake in units and monetary value.
• Result – win, loss, or push.
• Profit/Loss in units and monetary value.
• Running ROI, yield, and unit balance.

In addition, our data is updated in real time and is publicly accessible. Consequently, you can verify our performance independently. Visit our Historical Record Policy to see the full record.
