Bankroll and units
Set a budget, bet in units, and expect losing streaks even when you’re good.
Picking sides is the fun part. Managing money is the part that decides whether betting stays fun. It starts with two ideas: a bankroll and a unit.
Your bankroll
Your Glossary Bankroll Money set aside only for betting, sized so losing all of it wouldn’t hurt your bills, savings or life. Full glossary is money set aside only for betting. The test is simple: if all of it were gone, would your bills, savings or plans change? If yes, it’s too big. Set it before the season or the week starts, not in the middle of a bad Sunday.
Units
A Glossary Unit (u) A standard bet size. Results are tracked in units, not money, so a record reads the same no matter how much anyone bets. +4u means four standard bets ahead. Full glossary is your standard bet, a small, fixed slice of your bankroll. A common rule of thumb is a unit of about 1% to 2% of the bankroll. It’s a guideline, not a law; smaller is always fine.
Thinking in units does two things. It keeps every bet about the same size, so one loss can’t sink you. And it makes records comparable: “+4u” means the same thing whether someone bets small or large. That’s why FRD publishes everything in units, never money.
Losing streaks are normal, even for good bettors
This part surprises people. Suppose someone truly wins 55% of bets at −110. That’s well above the 52.4% Glossary Break-even rate The win rate you need to finish at zero units. At −110 it’s 52.4% (110 ÷ 210). Winning half your bets at −110 loses money. Full glossary Lesson: Reading odds and better than most bettors ever manage. Here is what pure chance still does to them:
And someone with no skill at all, a 50% bettor, is down after 100 bets about 69% of the time, but up the rest. That’s Glossary Variance Short-term luck. Even a good bettor has long losing runs, and a bad one can get hot for a month. It takes a lot of bets to tell the two apart. Full glossary . It’s why a hot month proves little, and why the closing line is a better early check.
Exact binomial math, assuming independent bets, no pushes, same price every time. Not a forecast for any bettor.
Rules that protect you
- Keep bets the same size. Don’t raise your stake to win back losses. That’s chasing, and it’s how small losses become big ones.
- Set a weekly limit in units before the games start, and stop when you reach it.
- Track every bet. People are bad at remembering results; the last lesson has the research. My Picks does this in units for free.
- Judge yourself on Glossary ROI Units won divided by units risked. +5% ROI means 5 units of profit for every 100 units bet. Pushes are left out. Full glossary and the close, not on one weekend.
Quick checkYou’ve lost four bets in a row. Should you double your next one to get back to even?Tap to see the answer
No. The next bet doesn’t know about the last four. Doubling up only makes the next loss twice as big. Keep the same unit, or take a break.
Key takeaways
- A bankroll is money you could lose entirely without it affecting your life.
- A unit is a small, fixed slice of it. Keep bets the same size.
- Even a true 55% bettor at −110 is down after 100 bets about 31% of the time. Streaks are normal.
- Never raise stakes to chase losses. Set a weekly limit before the games start.
