Bet Payout Calculator
How to Use the Betting Calculator
Enter your stake amount in the first field — this is how much you want to bet. Then enter the odds offered by your bookmaker in the second field. Select the correct odds format (decimal, fractional or American) from the dropdown to match how your bookmaker displays odds. Click "Calculate Payout" to instantly see your potential profit, total payout and the implied probability of the bet winning.
The calculator works for any sport or esport including CS2, Dota 2, League of Legends, football, basketball and more. All calculations are performed locally in your browser — no data is sent anywhere.
Understanding Odds Formats
Decimal Odds — The most common format for European and esports bookmakers. The number represents total return per unit staked. For example, odds of 2.50 mean a $10 bet returns $25 total ($15 profit + $10 stake). Higher decimal odds mean a less likely outcome with a bigger potential payout.
Fractional Odds — Traditional format used primarily by UK bookmakers. Displayed as a fraction like 5/2 or 3/1. The first number is the profit you win relative to the second number staked. So 5/2 means you win $5 profit for every $2 staked.
American Odds — Used mainly in the United States. Positive odds (+200) show how much profit you win on a $100 bet. Negative odds (-150) show how much you need to stake to win $100 profit. Positive = underdog, negative = favorite.

How the Bet Payout Calculator Works
Understanding how much a bet pays before you place it is fundamental to profitable CS2 betting. Our bet payout calculator eliminates guesswork by converting any odds format into clear dollar amounts. Whether your sportsbook displays decimal odds (common across European esports bookmakers), fractional odds (traditional UK format) or American odds (standard on US platforms), this tool handles the conversion instantly. Simply enter your intended stake, input the odds exactly as displayed by your bookmaker, select the matching format, and the calculator returns your potential profit, total payout and the implied probability embedded in those odds.
Using Implied Probability for Value Betting
The implied probability output is particularly valuable for CS2 bettors. Every set of odds implies a specific win probability for the outcome. When your own analysis suggests a team has a higher chance of winning than the odds imply, you have found a positive expected value bet. For example, if a bookmaker prices Team A at 2.40 decimal odds (implying roughly 42% win probability) but your research suggests they win 50% of the time in this matchup, the expected value is positive. Over hundreds of bets, consistently finding these edges is what separates profitable bettors from recreational ones. Use this calculator alongside our match predictions and odds comparison pages to identify value across CS2 betting markets.
Calculating Parlay & Accumulator Payouts
For parlay and accumulator bets, multiply the decimal odds of each individual selection together, then use the resulting combined odds in the calculator to determine the total parlay payout. A three-leg CS2 parlay with selections at 1.80, 2.10 and 1.65 produces combined decimal odds of 6.24, meaning a $10 stake returns $62.37 total. Parlays amplify both potential profit and risk, so the calculator helps you understand exactly what you stand to gain before committing your bankroll.
Betting Calculator FAQ
How do I calculate betting payouts?
Enter your stake amount and the odds offered by your sportsbook into our betting calculator. The tool instantly computes your potential profit (winnings above your original stake), total payout (profit plus returned stake) and implied probability. For example, with decimal odds of 2.50 and a $10 stake, the calculator shows $15.00 profit and $25.00 total payout. The formula behind it is straightforward: profit equals stake multiplied by (decimal odds minus one), and total payout equals stake multiplied by the decimal odds. Our calculator handles this math for all three major odds formats so you never need to convert manually.
What are decimal odds and how do they work?
Decimal odds represent the total return per unit staked, including your original stake. They are the standard format used by European sportsbooks and virtually all esports betting sites. Odds of 1.50 mean a $10 bet returns $15 total ($5 profit plus $10 stake), implying a 66.7% win probability. Odds of 3.00 mean a $10 bet returns $30 total ($20 profit), implying 33.3% probability. The higher the decimal odds, the less likely the bookmaker considers the outcome but the larger the potential payout. To convert decimal odds to implied probability, divide 1 by the decimal odds and multiply by 100. Decimal odds are the easiest format for calculating payouts and comparing value across different sportsbooks.
What are American odds and how do I read them?
American odds use positive and negative notation to indicate underdogs and favorites respectively. Positive odds like +200 tell you how much profit you win on a $100 stake — in this case $200 profit for a $300 total return. Negative odds like -150 tell you how much you need to stake to win $100 profit — here you must wager $150 to win $100. The further the number from zero, the more extreme the pricing: +500 is a heavy underdog (16.7% implied probability) while -500 is a strong favorite (83.3%). American odds are standard on US-based sportsbooks. To convert American odds to decimal, for positive odds use (American / 100) + 1, and for negative odds use (100 / absolute value) + 1.
What is implied probability and why does it matter?
Implied probability is the win percentage embedded within a set of betting odds. It represents the bookmaker's assessment of how likely an outcome is to occur, expressed as a percentage. Decimal odds of 2.00 imply a 50% chance, while odds of 4.00 imply 25%. Understanding implied probability matters because it allows you to compare the bookmaker's pricing against your own analysis. If you believe a CS2 team has a 60% chance of winning but the odds imply only 45%, the bet has positive expected value. Over time, consistently betting where your assessed probability exceeds the implied probability is the mathematical foundation of profitable sports betting. Note that the sum of implied probabilities across all outcomes in a market exceeds 100% — the difference is the bookmaker's margin (also called the vig or overround).
How do I calculate parlay and accumulator payouts?
A parlay (or accumulator) combines multiple individual bets into one wager where all selections must win for the bet to pay out. To calculate parlay payout, convert all selections to decimal odds and multiply them together. For a three-leg CS2 parlay with odds of 1.80, 2.10 and 1.65, the combined decimal odds are 1.80 x 2.10 x 1.65 = 6.237. Enter 6.237 as the decimal odds in our calculator along with your stake to see the total payout. A $10 bet at combined odds of 6.237 returns $62.37. Parlays offer dramatically higher payouts than individual bets but carry correspondingly higher risk, since a single losing selection voids the entire wager. Most professional bettors recommend limiting parlays to two or three legs to maintain a reasonable win probability.
How do I convert between odds formats?
Converting between decimal, fractional and American odds follows simple formulas. To go from decimal to fractional, subtract 1 and express the result as a fraction (decimal 2.50 becomes 3/2 or 6/4). To go from decimal to American, if the decimal is 2.00 or higher, multiply (decimal minus 1) by 100 to get the positive American odds (2.50 becomes +150). If the decimal is below 2.00, divide -100 by (decimal minus 1) to get the negative American odds (1.50 becomes -200). To convert fractional to decimal, divide the numerator by the denominator and add 1 (5/2 becomes 3.50). Our calculator handles all these conversions automatically, but understanding the math helps you quickly assess odds in any format you encounter across different CS2 betting sites.
What is expected value in CS2 betting?
Expected value (EV) measures the average profit or loss per bet over the long run. The formula is: EV = (probability of winning x profit if you win) minus (probability of losing x stake). A positive EV bet is one where the expected return exceeds zero, meaning it is mathematically profitable over many repetitions. For CS2 betting, if you believe Team A wins 55% of the time and the decimal odds are 2.00 (implying 50%), the EV on a $10 bet is (0.55 x $10) minus (0.45 x $10) = $1.00 per bet. This means every time you place this bet, you expect to profit $1.00 on average. Use our calculator to find the implied probability, compare it against your own assessment, and determine whether the expected value is positive before placing any CS2 wager.
