You can legally start sports betting with as little as $10 — but knowing the real costs involved helps you budget smarter from day one.
The sticker price to open a sportsbook account is $0. But the question of "how much does it cost to start?" involves a few more layers worth understanding before you deposit.
Minimum Deposits and Bet Sizes
Most major U.S. sportsbooks have a minimum deposit between $5 and $20. Minimum bet sizes are usually $1 to $5 per wager.
Realistically, starting with $50–$100 gives you enough to place a meaningful number of bets, learn the platform, and have a realistic sample size. Starting with less than $20 leaves almost no room for variance before you're out of money.
Here's a rough breakdown:
- $10–$20 — enough to try one or two bets, very limited runway
- $50 — comfortable for a few weeks of casual betting at $5–$10 per bet
- $100–$200 — a solid starting bankroll for learning with low stakes
The Hidden Cost: The Vig
Every standard bet comes with built-in sportsbook commission called the vig or juice. When you see odds of -110, you're paying roughly a 4.5% tax on every wager whether you win or lose over time.
That means if you bet $100 on a coin-flip game at -110 odds over 100 bets, even at exactly 50% wins you'll lose around $4.50 per bet on average. The vig is real, and it's the most important cost to understand.
Bonuses Reduce Your Effective Starting Cost
Most sportsbooks offer welcome bonuses — often a deposit match or a risk-free first bet worth $100–$1,000. These effectively reduce your cost of entry.
Read the terms carefully before claiming:
- Look for rollover requirements (how much you must bet before withdrawing bonus funds)
- Avoid bonuses with very high rollover multiples (10x+ is unfavorable)
- Site credit is not the same as cash — it usually can't be withdrawn directly
What Should You Actually Budget?
For a beginner who wants to learn without significant financial pressure, $100 is a reasonable starting bankroll. Bet 1–5% per wager ($1–$5), track every bet, and evaluate after 50–100 wagers.
