Odds Calculator

Enter one odds format. Stake is optional.

How this odds calculator works

American odds show how much you need to risk or can win on a $100 baseline. Positive odds like +145 mean a $100 bet returns $145 in profit, while negative odds like -110 mean you need to risk $110 to win $100.

Decimal odds convert that into a multiplier, and implied probability shows the bookmaker’s break-even percentage for the line.

• -110 converts to about 1.91 decimal odds and 52.38% implied probability
• +145 converts to about 2.45 decimal odds and 40.82% implied probability

Use the stake field to estimate potential profit and total payout for a straight bet.

What is an odds calculator?

An odds calculator helps bettors convert lines between American odds, decimal odds, and implied probability. It also estimates profit and total payout from a stake amount.

How this betting odds converter works

American odds show how much you need to risk or can win on a $100 baseline. Decimal odds show the total return multiplier, and implied probability estimates the break-even chance behind the line.

This calculator converts between those formats so you can compare markets more easily and understand what a line actually means.

How to use this odds calculator

1. Enter one odds format: American, decimal, or implied probability.
2. Optionally enter a stake amount.
3. Review the converted odds, implied probability, profit, and payout.
4. Use the results to compare prices across books or plan a bet size.

Odds calculator example

If you enter -110, this betting odds converter will show about 1.91 decimal odds and roughly 52.38% implied probability. If you add a $25 stake, it will also estimate your profit and total payout.

Why implied probability matters

Implied probability helps you compare your projected win chance to the market price. If you think a bet wins more often than the implied probability suggests, that may indicate value.
