Bankroll Management: How Much Should You Actually Bet?

Bankroll management is the single most important skill in sports betting — more important than picking winners. It's the set of rules that decides how much of your money touches any one bet, and it's what determines whether a bad week ends your ability to bet at all, or is just a bad week.

Step 1: Set a bankroll — money you can fully afford to lose

Your bankroll is a fixed amount of discretionary money set aside only for betting, separate from rent, bills, savings, or anything else. Treat it the same way you'd treat an entertainment budget for concerts or dining out: an amount that, if it went to zero, would be disappointing but not damaging.

If you're funding bets with money meant for bills, borrowed money, or money you're chasing losses to replace, that's a warning sign worth taking seriously — see our responsible gambling guide.

Step 2: Bet in units, not dollar amounts

A "unit" is a fixed percentage of your bankroll — commonly 1–5%. Thinking in units instead of dollars keeps your bet sizing consistent as your bankroll goes up or down, and it's how most bettors and handicappers communicate bet sizing without revealing exact dollar amounts.

Conservative

1 unit = 1% of bankroll

$1,000 bankroll → $10 per unit. Slow, steady, hard to go broke.

Moderate

1 unit = 2–3% of bankroll

$1,000 bankroll → $20–$30 per unit. The most common range recommended by experienced bettors.

Aggressive

1 unit = 5%+ of bankroll

$1,000 bankroll → $50+ per unit. Higher variance — a losing streak drains the bankroll fast.

Step 3: Size individual bets by confidence — within limits

Most staking plans let you bet more units on higher-confidence plays and fewer on longer shots — but cap the top end (many bettors cap any single bet at 3–5 units, even on a "lock") because no single game is ever a sure thing.

A simple flat-betting plan to start with

  1. Pick a bankroll you're fully comfortable losing.
  2. Set 1 unit = 1–2% of that bankroll.
  3. Bet 1 unit on standard plays, up to 2–3 units on your highest-confidence plays. Never more.
  4. Re-calculate your unit size monthly (or after a big swing), not after every single bet.
  5. Track every bet — stake, odds, result — in a simple spreadsheet. It's the only way to know if you're actually winning over time.

Why chasing losses is the most common way bettors go broke

"Chasing" means increasing bet size to try to win back a previous loss in one shot. It feels logical in the moment and is one of the fastest ways to turn a manageable loss into a serious one, because it abandons your sizing rules exactly when variance is already working against you. If you notice yourself chasing, that's a good moment to stop for the day and revisit our responsible gambling guide.

Takeaway: The bettors who last aren't the ones who pick the most winners — they're the ones whose bet sizing means no single day, week, or month can wipe them out.

Frequently asked questions

What's a realistic bankroll to start with?

There's no universal number — it should be an amount you've already decided you can fully afford to lose, sized to your own finances, not a figure other bettors use.

Should I increase my bet size after a winning streak?

Only if you recalculate your unit size as part of a planned schedule (e.g., monthly), not bet-by-bet in the moment. Sizing up impulsively right after wins is a common way to give the winnings back.

Is flat betting better than varying bet size by confidence?

Flat betting is simpler and lower-risk, which is why it's the standard starting point. Confidence-weighted sizing can work, but only within strict caps — it's easy to overestimate how confident you should be in any single game.

What should I do after a losing streak?

Stick to your existing unit size rather than increasing it to "catch up" — that's chasing losses, one of the most common ways bettors damage their bankroll. If it's affecting your mood or finances, see our responsible gambling guide.
