What is an Odds Converter Calculator?
An odds converter calculator is a simple tool that translates betting odds from one format to another—American, Decimal, and Fractional—while also showing the implied probability of a bet winning. Instead of doing the math yourself, you can plug the numbers in and quickly see how your odds compare across markets and sportsbooks.

How Does the Odds Converter Calculator Work?
The odds converter uses standard betting formulas to transform your input odds into every major format and calculate implied probability. That means one entry gives you a full picture: what the odds look like in other formats and what chance of success those odds represent.
Odds & Probability Formulas
- American → Decimal
- For positive odds (e.g., +150):
- Decimal = (American / 100) + 1
- For negative odds (e.g., -200):
- Decimal = (100 / |American|) + 1
- Decimal → American
- When Decimal ≥ 2.00 (underdogs / plus money):
- American = (Decimal − 1) × 100
- When Decimal < 2.00 (favorites / minus money):
- American = −100 / (Decimal − 1)
- Fractional → Decimal
- For odds like 3/2:
- Decimal = (Numerator / Denominator) + 1
- Implied Probability
- For positive American odds:
- Implied Probability (%) = 100 / (American + 100)
- For negative American odds:
- Implied Probability (%) = |American| / (|American| + 100)
Example:
American odds: +150
- Decimal odds:50
- Fractional odds:3/2
- Implied probability:100 / (150 + 100) = 40%
Total Payout:
Total Payout on a $100 stake: $250 (your $100 stake + $150 profit).
Odds Converter Profit Chart
An odds profit chart lets you see, at a glance, how much you stand to win at different price points. By fixing a stake amount (for example, $100) and listing common American odds (like -200, -110, +100, +150, +200, etc.), you can quickly compare potential profit and total payout without running multiple calculations.
Use the chart alongside this odds converter to:
- Check how much profit different odds would pay on your usual stake.
- See how small changes in the line (e.g., from +130 to +140) affect your bottom line.
- Compare offers from multiple Colorado sportsbooks to find the best return for the same bet.

Odds Converter Value and Strategies
The main job of this tool is conversion and probability, but it can also help you spot potential value. When you know the implied probability from your odds, you can compare it to your own estimate of a team or player’s chances.
Quick tips
-
Compare books – Convert odds and see which Colorado sportsbook offers the best price on the same bet.
-
Check your edge – If your estimated chance of winning is higher than the implied probability, the bet may offer value.
-
Beware big jumps – Very long odds mean very low implied probability, so keep your stake size sensible.
-
Track closing lines – Use the converter to compare the line you took vs. where the market closed.
Responsible Gambling
Sports betting in Colorado should always stay fun, controlled, and within your personal limits. An odds converter is a useful tool, but it’s not a guarantee of profit and should never be used to chase losses or gamble beyond what you can afford.

Frequently Asked Questions
1. What does the odds converter calculator do?
It converts your entered odds into American, Decimal, and Fractional formats and shows the implied probability of your bet winning. You only enter one number and the tool does all the conversions for you.
2. Which odds formats can I convert?
You can convert between American, Decimal, and Fractional odds. The calculator is designed so that entering any one of these automatically fills in the others.
3. Does this odds converter work for Colorado sportsbooks?
Yes. The tool works with standard odds formats used by regulated Colorado sportsbooks. As long as the odds follow industry-standard notation (e.g., -110, +150, 2.50, 3/2), you can use this calculator to interpret them.
4. What is implied probability and why is it important?
Implied probability is the percentage chance of an outcome winning as suggested by the odds. It helps you see whether a line is in line with your own expectations and can highlight when you’re potentially getting a good price.
5. Can I use the calculator for parlays?
The calculator is built for single-leg odds. You can still use it by converting each leg individually, but parlay probabilities and payouts will need separate calculations that combine multiple legs.
6. Why do my converted odds sometimes look slightly different from another site?
Minor rounding differences can occur when odds are converted and displayed to a set number of decimal places. The underlying math is the same, but presentation can vary (for example, rounding to two vs. three decimal places).
7. Is Fractional still important if I only bet with American odds?
Fractional odds are less common in U.S. sports betting but still appear in some markets (especially horse racing and international events). Knowing how to read them ensures you understand prices no matter where they’re posted.
8. Does converting odds change my payout?
No. Converting odds only changes how the price is displayed, not the underlying value. A bet at +150, 2.50, or 3/2 all represent the same payout structure for a given stake.
9. How often should I use the odds converter?
Any time you’re unsure what odds mean, comparing books, or trying to understand value, it’s worth running your numbers through the converter. It’s a quick check that can prevent misunderstandings before you place a bet.
