Why Track Your Bankroll?
Bettors who actually track their wagers consistently overestimate their long-term profitability. The gap between perceived and actual ROI is one of the most replicated findings in sports-betting research. Tracking forces honesty.
What This Tracker Does
- Logs every wager with date, sportsbook, stake, odds, and result.
- Calculates net profit/loss, ROI, and win rate automatically.
- Stores data locally via browser localStorage. Nothing uploads, nothing shared.
- Exports to CSV for backup or spreadsheet analysis.
Privacy
Your wagers never leave your browser. There is no backend, no signup, no analytics on your data. If you clear browser data or use a different device, the tracker resets — back up via CSV export periodically if you care about history.
Tracking Tips
- Log every wager — even the small ones. Sample-size bias kills bankroll tracking.
- Use consistent notes — "Eagles ML" vs "Eagles -3" vs "Eagles spread" should be standardized.
- Settle pending bets daily — open wagers don\'t count toward ROI until resolved.
- Export weekly — protect against browser data loss.
- Cross-reference against sportsbook activity statements — make sure your manual log matches operator reports.
