What this calculator does

This tool converts 1X2 (home, draw, away) odds into the equivalent Asian handicap, goal line (over/under) and correct score odds. Enter the three match prices and it derives the implied probabilities and fair lines with a Poisson goals model, so you can compare these markets on the same match at a glance.

How to use it

1. Enter the win, draw and lose decimal odds for the match.
2. Optionally set the payout for each target market (Asian handicap, goal line, score) — leave it at 1.0 for fair odds with no margin.
3. Click Calculate to see the 1X2 probabilities and the converted Asian-handicap, goal-line and score odds.

What it converts

• Asian handicap — the handicap line and prices implied by the 1X2 odds.
• Goal line (over/under) — the total-goals line and over/under prices.
• Correct score — score probabilities and the matching odds.

How to use it for analysis

• Spot value — compare the fair Asian-handicap or goal-line odds here with the bookmaker's actual price; if the book offers more than the fair line, that side may hold value.
• Cross-check markets — if the 1X2 price implies a strong favourite but the converted handicap looks shallow, the markets disagree and the match is worth a closer look.
• Read goal expectancy — the converted goal line reflects the total goals the odds imply; compare it with the over/under market to find over/under value.
• Use true probabilities — judge each outcome from the 1X2 probabilities (margin removed), not the raw odds, for a cleaner read of the real chances.

FAQ

What odds format does it use?

Decimal odds (for example 2.50). Convert fractional or American odds to decimal first.

How are the conversions calculated?

The 1X2 odds are turned into win/draw/lose probabilities, then a Poisson goals model derives the Asian handicap, goal line and correct-score odds.

What does the payout field do?

It sets the bookmaker margin for the converted market. 1.0 returns fair odds; a value below 1.0 applies that payout to the prices.

Is it free?

You can run the calculator for free, but viewing the full Asian-handicap, goal-line and score data requires VIP membership.
