Bankroll management is one of the most crucial aspects of gambling success. Regardless of whether you prefer roulette, blackjack, or slot machines, how you size your bets can drastically affect both your risk level and long-term enjoyment. Two of the most common methods are flat unit betting and percentage betting.
What Is Flat Unit Betting?
Flat unit betting means wagering the same amount every round, no matter whether you win or lose. For instance, a player might decide to stake $10 per spin in roulette and stick with that throughout the session.

Advantages:
- Predictable bankroll swings.
- Easy to manage and calculate.
- Lowers the risk of rapid bankroll depletion.
Disadvantages:
- Limited growth potential when on a winning streak.
- Can feel less exciting compared to more dynamic strategies.
- May not maximize opportunities when variance is in your favor.
How Percentage Betting Works
Percentage betting adjusts the size of your wager based on your current bankroll. For example, you might bet 5% of your total funds per round. If you win and your bankroll grows, the bet size increases. If you lose, the wager shrinks.

Advantages:
- Scales with your bankroll, protecting against big losses.
- Potential for exponential growth during winning streaks.
- Creates a more dynamic and engaging experience.
Disadvantages:
- Harder to calculate quickly, especially under pressure.
- Losing streaks can shrink bets to uninspiring levels.
- Requires discipline to avoid overestimating percentages.
Comparing the Two Approaches
Flat unit betting is perfect for casual players who want stability and control. It ensures long play sessions without the stress of fluctuating bet sizes.

Percentage betting, on the other hand, appeals to risk-takers and those with a strong bankroll strategy. While it can maximize gains, it can also frustrate players who dislike constantly adjusting stakes.
Which Strategy Is Best?
There is no universal “best” method—everything depends on personal preference, risk tolerance, and gambling goals.

- Choose flat unit betting if you value consistency and lower variance.
- Choose percentage betting if you prefer adaptability and growth potential.
Ultimately, both approaches can be effective tools when paired with responsible gambling practices.
