A unit is a fixed slice of your betting bankroll, often 1 to 2 percent. Betting the same unit on every straight play, and less on parlays, keeps one bad day from wiping you out. Never chase losses by raising your stake.
What a unit is
A unit is your standard bet size. Talking in units instead of dollars keeps everyone honest. A 1-unit play means the same thing whether your bankroll is $200 or $20,000.
Pick a bankroll first
Your bankroll is money set aside for betting that you can afford to lose. It is separate from rent, bills and savings. If losing it would hurt, it is too big.
How big should a unit be?
Many bettors use 1 to 2 percent of the bankroll per unit. Small units let you ride out normal losing runs.
| Bankroll | 1% unit | 2% unit |
|---|---|---|
| $250 | $2.50 | $5 |
| $500 | $5 | $10 |
| $1,000 | $10 | $20 |
| $2,500 | $25 | $50 |
Size parlays smaller
Parlays hit less often and swing harder. A common approach is a half unit or less on any parlay, and never more than a straight play.
No chasing
- Same unit after a loss. No doubling up to get even.
- Set a daily stop and honor it.
- Resize your unit on a schedule, not after a hot or cold streak.
- No bet is a lock. Nobody is owed a win.
Track everything
Log every bet: date, league, pick, odds, stake and result. It is the only way to know what is working. It is also how every Prolific Parlays pick gets logged and graded in public, wins and losses.
