Betting Odds Calculator: Fast, Free, and Accurate
For some people, betting odds are easy. But for those of us who are mathematically challenged? Odds are that foreign language that we only took a year of in high school.
And even if they are understandable, it looks simple until you’re staring at +250 and wondering what you’ll win if your bet hits. How does it translate?
Well, worry and wonder no more! We have a Betting Odds Calculator for you. What does it do? Only eliminate the math and the guessing, which is kind of a big deal. If you’re playing around with a $10 parlay or dropping some serious bank on an NBA underdog, all you have to do is plug in the odds, your bet amount, and you’ll get answers. It tells you your total payout, how much profit you’d pull in, and what the odds have to say about your chances.
It also converts between formats, so if one sportsbook shows +200 and another one has the dreaded decimals? Not a problem. You’ll see what it all means before you make your wager.
Once you use it, you’ll wonder how you ever lived without it! Scroll down to the tool, take it for a test drive, and see what your picks are really worth!

How to Use This Betting Odds Calculator
Using our betting odds calculator is easy peasy! Look below for a 4 step-by-step guide:
Step 1: Pick Your Odds Format
First up is choosing how you want the odds displayed:
- American (e.g. +250 or -120)
- Decimal (e.g., 3.50)
- Fractional (e.g., 5/2)
Step 2: Type in Your Odds
Enter the odds for your bet exactly as they appear. If you’re using American odds, make sure you include the plus or minus sign!
Step 3: Add Your Stake
Type in how much you’re planning to bet—our calculator works with any amount.
Step 4: Get Your Results
Once everything’s entered, you’ll immediately see the following:
- Payout – the total that you’d receive if the bet wins (including your stake).
- Profit – how much you’d pocket after getting your stake back.
- Implied Probability – what the odds say your chance of winning is as a percentage.
Want an example of how it’ll look? We gotchu!
If you’re betting $150 at +250 odds, here’s what the calculator shows:
- Payout: $525.00
- Profit: $375.00
- Implied Probability: 28.57%
It means that a $150 wager would return $525 total if it hits, and that includes your original bet. The odds are showing you that there’s a 28.57% chance of it landing.
FYI: You can toggle between odds formats at any time! If you want to see how the same bet looks as a decimal or fraction, just switch the format at the top. It’s a great way to compare value across different sportsbooks or double-check what you’re getting.
Why We Built This Tool
A lot of bettors have the same problem with odds, and it’s that they don’t always translate into simple numbers. American, decimal, and fractional formats all say the same thing but in different ways, and that doesn’t make them easy to understand. When you’re trying to figure out what your bet could return or how strong the implied probability is, a misread can throw everything off.
That’s why we built this calculator! It does the math instantly and lays it out in simple terms—payout, profit, and the percentage chance the odds represent. No math for you; just numbers that you can use.
It’s also part of a bigger suite of betting tools we’ve designed at GamblingSite.com, which were created to make things less confusing for casual bettors to those who are chasing value on multiple online sportsbooks!
What the Calculator Tells You
Once you input your numbers? The calculator calculates the answers, and here’s what you get:
- Total Payout – The full amount you’d get back if your bet hits, including your original stake.
- Profit – The extra cash you’d earn on top of what you bet.
- Implied Probability – A percentage that breaks down what your odds say about the chances of you winning.
