This calculator helps you determine bet amounts and potential profits based on the Martingale System—one of the most well-known money management strategies in gambling. On this page, we also explain how the Martingale method works and what to watch out for when using it.

Recovering
The calculator under the “Recovering” tab helps you determine how much you need to bet next in order to fully recover your accumulated losses.
Enter the amount you want to recover in the Total Lost Amount field. In the Next Bet Odds field, input the decimal odds of the selection you plan to bet on. The Expected Return field is for entering any additional profit you’d like to make on top of recovering your losses. If your goal is simply to break even, leave this field at 0.
Once you fill in these three fields, the calculator will show the required stake in the Next Stake Amount field.
For example, suppose you want to recover $1,000, and you're planning to place your next bet on a football match with decimal odds of 1.76. After analyzing the match thoroughly, you believe there’s a high chance your prediction will be correct. If you set your desired profit at $100, the calculator will show that you need to bet $1,447.
Try running the numbers: if you bet $1,447 at 1.76 odds and win, your payout will be $2,546.72. Subtract your $1,000 in previous losses and your $1,447 stake, and you're left with a profit of $99.72. While there's a slight rounding difference, it's nearly the $100 profit you aimed for.
Simulation
The calculator under the “Simulation” tab shows the progression of bet amounts when using the Martingale system. Enter your initial bet amount, then choose a strategy: whether to multiply your next bet by 1.5x, 2x, or 3x after each loss. The calculator will automatically display the bet amounts for rounds 2 through 7 based on your selection.
What Is the Martingale System in Gambling?
The Martingale System is one of the most popular betting strategies used in gambling, especially in games with even-money outcomes like roulette, blackjack, or sports betting.
It’s simple to understand and appeals to players who want a structured approach to managing their bankroll. But while the system sounds promising, it also comes with real risks that you should consider before using it.
How the Martingale System Works
At its core, the Martingale System is a progressive betting strategy. The idea is simple: every time you lose a bet, you double your stake. Once you win, you go back to your original starting bet. The logic behind this system is that a single win will recover all previous losses and result in a small profit equal to your original bet.
For example:
Bet 1: $10 – lose
Bet 2: $20 – lose
Bet 3: $40 – lose
Bet 4: $80 – win → total loss = $10 + $20 + $40 = $70; total win = $80 → profit = $10
As you can see, the moment you win, you’re back in the green.
The Risks and Limitations
Despite its simplicity, the Martingale System comes with serious downsides:
1. Table Limits or Maximum Bets
Most casino and sportsbooks have bet limits. After several consecutive losses, you may reach the limit before recovering your losses, rendering the strategy useless.
2. Rapid Bankroll Drain
Even a short losing streak can require huge bets. For instance, after just 6 losses starting from $10, you’d need to bet $640 on your next round, with a total of $630 already spent.
3. False Sense of Security
Some players believe that a win is “bound to happen soon.” But probability doesn’t work that way. Each bet is independent, and long losing streaks can and do happen.
When (and If) to Use the Martingale
If you're thinking about using the Martingale System, keep these tips in mind:
- Only use it with a fixed budget you're willing to lose
- Stick to even-money bets with predictable odds
- Understand the risks before you start
- Avoid chasing losses indefinitely
Some bettors use a modified Martingale or Mini Martingale, where you stop doubling after a few rounds to limit risk. Others use it for short-term sessions only, not as a long-term plan.
The Martingale System can be an interesting tool for managing your bets in gambling, but it’s far from foolproof. While it promises small, consistent wins, it carries the risk of sudden, large losses. Use it carefully, and never bet more than you can afford to lose.
Whether you're into online casino games or sports betting, understanding betting systems like Martingale can give you insight into how to approach risk. Just remember: no betting strategy can eliminate risk entirely.
