Definition
The stake (also called the wager or bet amount) is the amount of money you put at risk on a single bet. If you win, you receive your stake back plus the profit. If you lose, you forfeit your stake entirely. Proper stake sizing -- determining how much to bet on each wager -- is one of the most critical skills in successful sports betting.
How It Works
Your stake should be determined by your bankroll management strategy, not by emotion or gut feeling. Common approaches include flat betting (same fixed amount), percentage-based (a fixed % of current bankroll), and Kelly Criterion (stake proportional to your estimated edge). The goal is to size bets so that you survive inevitable losing streaks while maximizing growth when winning.
Example
With a $1,000 bankroll and a 2% fixed staking strategy:
- Each bet: $20 (2% of $1,000)
- Bet at odds 2.00: if won, return = $40 (profit $20); if lost, lose $20
- After winning 3 and losing 2: net change approximately +$20, bankroll = ~$1,020
The stake stays at 2% of the current bankroll, adjusting slowly over time.
Why It Matters
Your stake size determines how quickly you grow your bankroll and how quickly you can go broke. Betting too large (e.g., 10-20% per bet) exposes you to the risk of ruin even with a positive edge. Betting too small limits your growth. The sweet spot -- typically 1-3% per bet for flat staking or fractional Kelly -- balances growth and survival. No matter how good your picks are, poor stake sizing will eventually destroy your bankroll.
