The difference between a recreational bettor and a serious one can often be summed up in two words: tracking bets. Without records, you are flying blind.
What to Track
Essential Fields
| Field | Example | Why It Matters |
|---|---|---|
| Date | 2026-03-05 | Identifies trends over time |
| Sport | Football | Filters by sport for ROI analysis |
| Event | Arsenal v Chelsea | Context for the bet |
| Market | Match Result | Reveals which markets you profit from |
| Selection | Arsenal Win | Your specific pick |
| Odds | 2.10 | Needed for ROI and CLV calculations |
| Stake | £10 | Tracks total outlay |
| Result | Won | Calculates P/L |
| Profit/Loss | +£11.00 | Bottom-line performance |
Optional but Valuable Fields
- League/Competition -- drill down into which leagues you read well
- Bookmaker -- spot which books offer you the best odds
- Reasoning -- brief note on why you placed the bet (forces pre-bet analysis)
- Closing odds -- compare to your bet odds for CLV tracking
How to Calculate Key Metrics
ROI (Return on Investment)
ROI = (Total Profit / Total Stakes) x 100
A £50 profit from £1,000 in stakes = 5% ROI. Over 500+ bets, anything above 3% suggests genuine edge.
Yield per Bet
Yield = Total Profit / Number of Bets
This tells you how much you earn per bet on average. A yield of £0.50 per bet means every bet is worth 50p in expected profit.
Strike Rate
Strike Rate = Winning Bets / Total Bets x 100
A 45% strike rate at average odds of 2.50 is profitable. A 60% strike rate at average odds of 1.30 may not be.
Monthly Review Process
- Update all outstanding bet results
- Calculate monthly ROI, yield, and strike rate
- Compare to your cumulative numbers
- Identify your top 3 profitable and bottom 3 unprofitable areas
- Adjust next month's betting plan accordingly
Getting Started
Open a spreadsheet, create columns for the essential fields above, and log your next bet. The barrier to entry is zero -- the discipline to maintain it is what separates serious bettors from the rest.
