Martingale Calculator
Calculate progressive betting stakes using the Martingale system. Understand the required bankroll to try and earn a desired profit given previous losses.
What Is the Martingale System?
The Martingale betting system is a popular strategy among bettors looking to recover losses and secure a net profit. This system is based on doubling your stake after each loss, ensuring that a single win can recoup all previous losses and generate a profit equal to your original bet.
While the concept is straightforward, calculating the appropriate bet size at each step can be complex, especially when odds vary. This is where a Martingale Calculator becomes invaluable.
| Advantages | Risks |
|---|---|
| A simple concept that's easy to understand. | Requires substantial capital due to exponential growth in stakes. |
| Potentially recovers all losses with one win. | Betting limits imposed by casinos or sportsbooks can halt progression. |
| Suitable for even-money bets in controlled environments. | A long losing streak can result in significant financial losses. |
How to Calculate a Martingale Bet
This system assumes unlimited funds and no betting limits, which are rarely realistic. Variations like the Grand Martingale or Reverse Martingale add complexity but follow similar principles.
- Start with an initial stake (e.g., $10).
- If you lose, double your stake on the next bet (e.g., $20).
- Continue doubling until you win.
- Once you win, revert to your original stake (e.g., $10).
Our Martingale Calculator is designed to simplify calculating stakes and understanding the progression of your bets. You can determine how much to wager at each stage by inputting specific variables and predicting your total investment, potential winnings, and net profit. Let's break down the calculator's inputs and outputs.
Inputs Explained
Desired Profit
This input allows you to specify exactly how much profit you want to make from your betting sequence. For example, entering $200 means you're aiming to end up with $200 in net profit after recovering all previous losses. This target influences the size of your next bet, as the calculator will determine the exact stake needed to achieve this profit amount if your next bet wins.
Total Loss
This field is where you enter the cumulative amount you've already lost in your current betting sequence. For instance, if you've lost $100 across previous bets, entering this value helps the calculator determine the minimum stake required to recover these losses. The calculator uses this value as a baseline for calculating your next bet size to ensure you can recoup all previous losses plus achieve your desired profit.
Odds
Odds represent the payout multiplier for a successful bet. The calculator allows you to input odds in either decimal or American format. For example, decimal odds 2.00 mean you'll receive $2 for every $1 wagered. Otherwise, American odds of +100 also represent even money (2.00 in decimal).
Odds are crucial in determining how much you need to wager after a loss to recover previous losses and achieve your desired profit. Lower odds require higher stakes, while higher odds reduce the required stake.
Outputs Explained
Next Bet
This output shows the exact amount you should wager on your next bet to recover all previous losses and achieve your desired profit if this bet wins. For example, if you've lost $100 and want a $10 profit at odds of 2.00, the calculator might suggest betting $110.
Initial Loss
This output displays the amount you've already lost before placing your next bet, confirming the value you entered in the Total Loss field. It serves as a reference point to understand how much you need to recover through your next bet.
Total Investment
This shows the cumulative amount you'll have wagered after placing your next bet. It combines your previous losses with your next bet amount to give you a complete picture of your financial commitment. For example, if you've already lost $100 and your next bet is $110, your total investment would be $210.
Where Bettors Use the Martingale System
Casino Games
The Martingale system is commonly used in games with even-money bets, such as roulette (red/black) or blackjack (win/lose). These games offer consistent odds, making the strategy more straightforward to apply.
Sports Betting
In sports betting, odds vary significantly between events. The calculator helps adjust stakes based on fluctuating odds, ensuring accurate calculations for recovering losses.
Forex and Stock Trading
Some traders adopt the Martingale system by increasing position sizes after losses, hoping to recoup them when markets rebound.

Is the Martingale system guaranteed to work?
No betting system guarantees success. The Martingale system relies on recovering losses through exponential stakes, which can lead to significant financial risk during losing streaks.
What happens if I hit a casino's betting limit?
If you reach a casino's maximum bet limit before winning, you won't be able to continue doubling your stakes, effectively breaking the system.
Can I use the Martingale system with varying odds?
Yes, but it requires careful calculation of stakes based on each event's odds. Our calculator simplifies this process by automatically adjusting stakes for varying odds.
How much starting capital do I need?
Your starting capital depends on your initial stake and tolerance for risk during losing streaks. A higher bankroll reduces the likelihood of running out of funds before recovering losses.
Is there an alternative to doubling my stakes?
Variations like the Grand Martingale add extra amounts to each doubled stake for higher potential profits but come with increased risk.
