Ask anyone who bets on sport how they are doing and you will usually get a feeling, not a number. “Slightly up this season.” “About even.” The trouble is that memory is a poor accountant: a last-minute winner at odds of 4.50 stays with you for months, while the five small losses before it fade by the next weekend.
Tracking your bets replaces that feeling with a record. This guide covers why it matters, exactly what to note for each bet, the handful of numbers worth calculating, and the three practical ways to keep it going: a notebook, a spreadsheet or an app.

Why track your bets at all
Most people who bet regularly have never added up what they staked over a month. That is not carelessness; nothing in the way betting works pushes you to do it. Each bookmaker app shows its own history in its own format, and if you use two or three of them, your results are split across as many screens. Deposits and withdrawals tell you even less, since they mix money you won with money you simply moved around.
A simple record of your bets fixes three things at once:
- You see your real result. Not the big wins you remember, but the sum of everything: the wins, the losses, the void bets and the cash-outs.
- You see what betting costs you. The total you stake each week or month is the clearest measure of how much room betting takes in your budget, whatever the results.
- You see your habits. Which sports, markets and bet types you actually use, how your stakes change after a bad run, and whether your biggest bets are your best ones.
None of this requires you to change how you bet. It only asks you to write it down. What you do with the answers is up to you.
What to record for every bet
The aim is to note enough to calculate your results later, without making each entry a chore. These fields cover almost everything you will want to know:
- Date of the bet (and of the event, if it is far ahead).
- Bookmaker, so you can compare and check against your accounts.
- Sport and competition: football, Premier League; tennis, ATP Masters; and so on.
- Event and selection: the match, and what you backed in it.
- Market: match result, over/under, both teams to score, player props, handicap…
- Bet type: single, parlay (accumulator) or system bet, with the number of legs.
- Odds, ideally in decimal format, which is the easiest to calculate with. If your bookmaker shows fractional or American odds, our guide to implied probability explains how to convert them.
- Stake: the amount you put on the bet.
- Status: won, lost, void, cashed out or still pending.
- Return: what the bookmaker paid back, stake included. Zero for a lost bet.
Optional fields become useful once you have a few dozen bets: live or pre-match, a tag for the reason behind the bet (a tipster, a system you are testing, a hunch), and a short note.
| Date | Sport | Selection | Type | Odds | Stake | Status | Return |
|---|---|---|---|---|---|---|---|
| Oct 4 | Football | Arsenal to win | Single | 1.85 | $10 | Won | $18.50 |
| Oct 5 | Tennis | Sinner to win | Single | 1.65 | $15 | Lost | $0.00 |
| Oct 5 | Football | 3 home wins | Parlay ×3 | 5.20 | $5 | Lost | $0.00 |
| Oct 6 | Basketball | Over 221.5 pts | Single | 1.90 | $10 | Won | $19.00 |
The numbers that tell you where you stand
Once your bets are written down, a few sums give you the full picture.
Net result
Everything you got back, minus everything you staked. It is the only number that says whether you are up or down.
Net result = total returns − total staked
Total staked
The sum of all your stakes over a period. Compare it with what you planned to spend: it is the first number to watch if you want to keep betting within a budget. Our guide to bankroll management covers how to set that budget.
ROI
Return on investment puts your net result in proportion to what you staked, so you can compare periods of different sizes.
ROI = net result ÷ total staked × 100
Say you placed 50 bets of $10 over a month. You staked $500 and got $465 back. Your net result is −$35 and your ROI is −35 ÷ 500 = −7%: on average, each dollar staked came back as 93 cents. The complete guide to betting ROI goes further, with a calculator.
Win rate, with care
The share of your bets that won. It is the number people quote most, and the one that misleads most: winning 60% of bets at odds of 1.50 loses money, while winning 35% at odds of 3.20 can come out ahead. Always read it next to your average odds and your ROI.
Notebook, spreadsheet or app: three ways to track
The best method is the one you will still be using in three months. Here is how the three usual options compare.
A notebook
Zero setup and nothing to install. It is a fine way to start noticing what you stake, but the sums are up to you, errors creep in, and you cannot filter by sport or bet type without going back through every page.
A spreadsheet
Excel or Google Sheets can calculate your net result, ROI and win rate automatically, and filters let you slice your history any way you like. The cost is typing: every bet means copying eight or ten fields by hand, and a parlay can mean several rows. We made a free betting spreadsheet template with the formulas already in place if you want to go this way.
An app
A bet tracking app keeps the spreadsheet’s calculations and removes most of the typing. With BetTrack, you take a screenshot of your bet slip in your bookmaker’s app and share it: the bets on the image are read and logged, with their odds, stake and status, and duplicates are skipped. It works with any bookmaker because it reads the screenshot, not your account, so it never asks for your bookmaker login. To compare apps before you pick one, see how to choose a bet tracker app.
| Notebook | Spreadsheet | App | |
|---|---|---|---|
| Setup | None | An hour, or a template | A download |
| Time per bet | A minute | 1 to 2 minutes | A few seconds |
| Calculations | By hand | Automatic | Automatic |
| Breakdowns by sport or type | Painful | With filters | Built in |
| Typing errors | Frequent | Frequent | Rare (you check) |
Make it a habit that lasts
Most records die in the second week. A few rules keep yours alive:
- Log the bet when you place it, not at the end of the week. A screenshot taken straight away is enough; you can enter it later.
- Settle pending bets as soon as the result is in. A pile of “pending” bets makes every number wrong.
- Keep one format for the whole record: the same fields, the same odds format, the same currency.
- Review once a week, for ten minutes: total staked, net result, anything unusual.
- Never delete a bad week. If it happened, it belongs in the record.
What to look for once you have data
After 50 to 100 bets, your record starts to say something beyond the overall total. Break your results down and look for differences:
- By sport and market: do some cost you much more than others?
- Singles versus parlays, and parlays by number of legs. The bookmaker’s margin grows with each leg, which our article on parlays and singles explains in detail.
- By odds range: short favourites, middle odds, long shots.
- By stake size: are your biggest stakes on your worst bets?
- Stakes after losses: if your stakes climb after a losing run, you are chasing losses, and the record shows it plainly.
- Football7454%
- Tennis4156%
- Basketball3241%
ROI by leg count
Keep sample size in mind. Over 30 bets, a few results either way swing every percentage; a difference between two sports means little until each has dozens of bets behind it. Treat early numbers as a description of what happened, not as a forecast.
What tracking can and cannot do
A record shows you what happened. It does not change the odds, it does not make the next bet more likely to win, and no amount of analysis turns betting into a reliable source of income. Bookmakers build a margin into every price, and over time that margin works against the bettor.
Where tracking really helps is in keeping betting in its place. If your total staked keeps exceeding what you planned, if your stakes rise after losses, or if you find yourself betting to win back money, those are signals to slow down or stop.
Frequently asked questions
Should I track small bets and bets placed with friends?
Yes. Every bet that involves money belongs in the record, however small. Small stakes add up, and leaving them out makes your total staked look lower than it is.
How many bets before my stats mean anything?
Your total staked and net result are accurate from the first bet. Percentages such as win rate and ROI need far more: over a few dozen bets they swing a lot, and comparisons between sports or bet types only become meaningful after hundreds.
Can I track bets from several bookmakers in one place?
Yes. A spreadsheet works if you type each bet in. An app that reads bet slip screenshots, like BetTrack, handles any bookmaker without connecting to your accounts.
Is tracking my bets a betting strategy?
No. Tracking is a record of what you have already done. It helps you see your real results and spending, but it does not predict outcomes or improve your chances of winning.
Betting involves risks, including losing the money you stake. BetTrack makes no promise of winnings. 18+ only. Responsible gambling and where to find help
