ROI tracker
Log bets and see running ROI, win rate, average odds
Log your bets and see running statistics — ROI, win rate, average odds, and a profit curve.
What does it track?
A lightweight bet journal that lives in your browser session. Add each bet with stake, odds and result (win/lose/push). It computes your running ROI, win rate, average odds, total profit, and shows a running P&L curve. For serious long-term tracking use a spreadsheet — but for quick session math or testing whether a system actually works, this is faster. Cross-check your numbers against Break-even calculator and track CLV via our CLV calculator for true edge measurement.

Example: 10-bet session
Log 10 bets over an evening: 6 won at average 1.85 odds, 4 lost. Stake €20 each = €200 total. Winnings: 6 × €17 net profit + 4 × €20 loss = €102 − €80 = +€22. ROI = 22/200 = 11%. Strong session — but with only 10 bets, variance dominates.
When to use
- Testing a new betting system over a short trial
- Tracking a specific tipster's performance
- Quick session math without spreadsheet overhead
