Explain It Like I'm in Fifth Grade
A unit is like using the same measuring cup every time you cook.
Instead of saying, "I bet a lot" or "I bet a little," you choose one normal amount and call it one unit.
For one person: 1 unit may be $1.
For another person: 1 unit may be $10.
The dollar amount should be based on that person's own bankroll, not someone else's.
Simple Example
Your bankroll is $200.
You decide that one unit equals $4.
That means:
- 0.5 unit = $2
- 1 unit = $4
- 2 units = $8
If you win $12, you gained three units.
If you lose $8, you lost two units.
Why It Matters
Units make it easier to compare results without focusing only on dollar amounts.
They also help you avoid changing your wager size without a clear reason.
Biggest Beginner Mistake
A common mistake is copying another bettor's dollar amount.
Someone with a $5,000 bankroll can handle a different wager size than someone with a $100 bankroll.
Playbook Tip
Keep your normal unit small. A common conservative approach is approximately 1% to 2% of a bankroll, but no percentage removes risk.
Important Rules to Check
Remember:
- Your unit size is a personal budgeting choice, not a prediction of how likely a bet is to win.
