The short answer: log five things for every session — date, stakes, buy-in, cash-out, and duration — then let those numbers roll up into three metrics that actually mean something: lifetime net profit, win rate (bb/100), and hourly rate ($/hr). You can do it in a spreadsheet, but a phone app removes the friction that makes most people quit after a month.
Why track at all?
Human memory is a terrible bankroll manager. We remember the big hero call and forget the four quiet losing nights around it. Tracking fixes three specific blind spots:
- Are you actually winning? Most players who "feel" like winners are break-even once rake and the occasional blow-up night are counted.
- Which games pay you? You may crush the $1/$2 home game and quietly bleed at the casino $2/$5 — the numbers say which is which.
- How much variance are you riding? Seeing the swings on a graph makes downswings feel normal instead of catastrophic, so you play your best under pressure.
What to record for each session
You only need five fields. Everything useful is derived from them:
- Date — so you can trend results over weeks and months.
- Game & stakes — e.g. "NL Hold'em $1/$2." Stakes are what let you express results in big blinds.
- Buy-in (with rebuys) — every dollar that went in, not just the first stack.
- Cash-out — what you walked out with.
- Duration — start and end time. This is the field people skip, and it's the one that unlocks hourly rate.
The three metrics that matter
1. Lifetime net profit
The headline number: cash-outs minus buy-ins, across every session. It's the honest scoreboard, and watching it climb is what makes the habit stick.
2. Win rate (bb/100)
Your profit expressed in big blinds per 100 hands. Because it's normalized to stakes, it's the only fair way to compare how well you play across different games. A solid live win rate is a few bb/100; anything consistently positive over a big sample means you're beating the game.
3. Hourly rate ($/hr)
Net profit divided by hours played. This is the number that tells you what the game is worth to your time — the difference between a profitable hobby and one you'd be better off skipping. You can work out your hourly rate with our free calculator.
How to actually do it
There are three common approaches, in rough order of how long people stick with them:
- Notes app / paper — zero setup, but no math and no graphs. Fine for a weekend, useless over a year.
- Spreadsheet — flexible and free, but you're the database: manual entry, your own formulas, and it lives on a laptop you don't bring to the table. Most people abandon it. (Here's an honest spreadsheet-vs-app comparison.)
- A tracking app — log a session in seconds from your phone at the table, and every metric above is computed for you automatically.
Whichever you pick, the rule is the same: log the session the moment it ends, while the numbers are in front of you. The best tracker is the one you'll still be using in six months.
