Definition
Flat betting is the simplest and most conservative staking strategy. You wager the same fixed amount on every bet -- typically between 1% and 3% of your initial bankroll -- regardless of the odds, the sport, or how confident you feel about a pick. There is no adjustment based on perceived edge.
How It Works
Define your bankroll (e.g., $1,000), choose a unit size (e.g., 2% = $20), and bet that exact amount every time. You may recalibrate periodically (e.g., monthly) if your bankroll has changed significantly, but day to day, the stake stays constant.
Example
Bankroll: $1,000, flat stake: $20 (2%)
| Bet | Odds | Result | P&L | Bankroll |
|---|---|---|---|---|
| 1 | 1.85 | Won | +$17 | $1,017 |
| 2 | 2.10 | Lost | -$20 | $997 |
| 3 | 1.75 | Won | +$15 | $1,012 |
| 4 | 3.20 | Lost | -$20 | $992 |
| 5 | 1.95 | Won | +$19 | $1,011 |
The stake stays at $20 no matter what. Simple, disciplined, effective.
Why It Matters
Flat betting is the best starting point for new bettors. It prevents the common trap of increasing stakes after losses (chasing) and removes emotional decision-making from stake sizing. The downside is that it does not maximize strong edges -- you bet the same on a 15% value bet as on a 2% value bet. Once you are confident in estimating probabilities, graduating to fractional Kelly can improve returns.
Flat betting is recommended for beginners. Once you master probability estimation, consider fractional Kelly to optimize your growth.
