Most sports bettors lose money not because they pick the wrong games — but because they bet the wrong amounts. Bankroll management is the single most important skill in sports betting, and it's the one most people skip entirely.

What Is a Bankroll?

Your bankroll is the total amount of money you've set aside exclusively for betting. Not your rent money. Not your savings. A separate pool of cash that you can afford to lose completely without it affecting your life.

If you can't define that number, stop here and figure it out before placing another bet.

The Unit System

Professional bettors think in units, not dollars. One unit is typically 1-3% of your total bankroll.

Bankroll	1 Unit (1%)	1 Unit (2%)	1 Unit (3%)
$500	$5	$10	$15
$1,000	$10	$20	$30
$5,000	$50	$100	$150

Why units matter: If your bankroll is $1,000 and you're betting $100 per game, you're risking 10% on a single bet. A bad three-game stretch wipes out 30% of your bankroll. At 1-2% per bet, that same losing streak costs you 3-6% — barely a dent.

The 1% Rule

Start with 1% per bet. It sounds painfully small. That's the point.

At 1% per bet, you'd need to lose 100 straight bets to go broke. That's essentially impossible. Meanwhile, consistent 1% winners compound over time. A bettor hitting 55% of their bets at -110 odds, wagering 1% per game, will grow their bankroll roughly 15-20% per month.

When to Increase Bet Size

Only increase your unit size when your bankroll grows. If you started with a $1,000 bankroll and it's now $1,500, your 1% unit moves from $10 to $15. This is called the Kelly Criterion approach (simplified) — your bets scale with your success.

Never increase bet size to chase losses. If your bankroll drops from $1,000 to $700, your unit drops to $7. Protect what you have.

The Three Rules

Never bet more than 3% on a single game. Even your most confident play doesn't deserve more than 3 units.
Never chase losses. Tomorrow's games don't know about today's losses. Doubling up to "get even" is how bankrolls die.
Track everything. You can't improve what you don't measure. Log every bet, the odds, the result, and your reasoning.

What This Looks Like in Practice

Say you have a $1,000 bankroll and you've identified three plays for tonight:

Lakers -3.5 (-110): Medium confidence → 1 unit ($10)
Bills ML (-150): High confidence → 2 units ($20)
Padres/Dodgers Over 8.5 (-105): Low confidence → 1 unit ($10)

Total risk: $40 (4% of bankroll across three bets). If all three lose, you're down 4%. If all three hit, you're up roughly $35. That's the game — small, consistent, sustainable.

How Off The Bench Helps

Bankroll management only works if you have good picks to bet on. That's where Off The Bench comes in. Ask it about any game and it'll pull live odds, check injuries, and give you a confidence-rated prediction — so you know which plays deserve 1 unit and which deserve 2.

Try asking: "What are the best NBA bets tonight? I'm looking for high-confidence plays only." It'll give you a focused shortlist instead of overwhelming you with every game on the slate.

The Bottom Line

Bankroll management won't make bad picks good. But it will keep you alive long enough for your good picks to compound. The bettors who last aren't the ones who hit a 10-leg parlay — they're the ones who bet 1-2% per game, hit 54% of their picks, and let math do the work.
