How to Calculate Betting ROI (And Why Most Tipsters Lie)

Sports betting is an industry filled with bold claims and fake screenshots. When you are scrolling through Twitter or Telegram, it is easy to get caught up in the hype of a huge winning accumulator. But how do you know if a tipster is actually profitable long-term?

The Mathematical Reality

The only metric that truly matters in sports betting is Return on Investment (ROI). Not strike rate, not the number of points profit (which can be manipulated by high stakes), and definitely not how many times they post the “money bag” emoji.

“ROI is simply: Total Profit / Total Staked x 100. If a tipster cannot provide this figure, verified by an independent third party, do not give them your money.”

How to spot a fake record

  • Deleted Losing Tips: They post 10 tips, 3 win, 7 lose. They delete the 7 losers and claim a 100% strike rate.
  • After-Timing: Posting a “winning slip” for a bet they never actually shared before the event started.
  • Unrealistic ROI: Any tipster claiming a sustained ROI of over 30% long-term across thousands of bets is almost certainly lying. Even the best syndicates in the world operate at a 5-10% edge.

Why independent verification matters

This is exactly why we built Compare The Tipster. When a tipster posts on our platform, the odds are locked, the timestamp is recorded, and the result is graded automatically. They cannot delete losers. They cannot manipulate the odds. What you see is exactly what they have achieved.
