ROI in Betting: What It Is and How to Calculate It

27.05.2025
ROI (Return on Investment) is a key performance indicator for bettors and tipsters. It shows how profitable your betting strategy is, expressed as a percentage. ROI can be either positive or negative:

✅ A positive ROI means your bets are profitable.
❌ A negative ROI means you’re losing money.

🔍 For accurate evaluation, you should have between 500 and 1000 bets. A solid ROI usually starts from 5% and up.

💡 How is ROI calculated?

The formula is simple:
ROI = (Net Profit / Total Amount Staked) x 100

📈 Example:

You placed 20 bets of $ 1.11 each, and made a net profit of $ 2.78.

  1. Total amount staked: 20 x $ 1.11 = $ 22.20
  2. Net profit: $ 2.78 ÷ $ 22.20 = 0.125
  3. ROI: 0.125×100 = 12.5%

Now let’s look at a loss scenario:

You placed the same 20 bets of $ 1.11, but your net loss was -$ 1.67.

  • Total amount staked: $ 22.20
  • Net profit: -$ 1.67 ÷ $ 22.20 = -0.075
  • ROI: -0.075×100 = -7.5%

📊 ROI Over the Long Term:

The more bets you place, the more accurate your ROI becomes. Ideally, ROI should be calculated over at least 500−1000 bets.

⚠️ What’s a Good ROI?

  • 5% or more over 1000 bets is considered strong performance.
  • Even 1−2% is acceptable, but aiming higher is ideal.

🔗 Key takeaway: ROI isn’t just a number — it’s a measure of how effective your betting strategy is.
