Betting Odds Converter
Type a price in whatever format your bookmaker shows and get the other three straight back, plus the chance it implies. Handy when an in-play price flashes up and you need to know what it really means.

One price, four languages
Decimal
The number you multiply your stake by to get everything back, stake included. £5 at 3.40 brings home £17. Exchanges and most betting apps default to it, and it makes the quick maths easy.
Fractional
Profit on the left, stake on the right. 11/8 pays £11 for every £8 you risk, so a fiver wins £6.88 and you get the fiver back too. Still the language of the betting shop.
American
A minus sign shows what you stake to win 100; a plus sign shows what 100 wins. −125 means £125 to win £100, while +240 means £100 nets you £240.
Implied chance
One divided by the decimal price. 3.40 says 29.4%. That figure has the bookmaker's margin baked in, so set it against your own read of the game.
Reading a live price
Home side 1-0 up at the break
The in-play market flashes up 4/9. Run it through and you get 1.44 decimal, −225 American and a 69.2% implied chance. If the match stats show they've been battered on possession and shots on target, 69% looks generous. If they've bossed it and their ELO rating had them clear favourites before kick-off, it's about right. The converter gives you the number. The live data tells you whether to trust it.
Prices you'll meet every weekend
| Decimal | Fractional | American | Chance |
|---|---|---|---|
| 1.25 | 1/4 | −400 | 80.0% |
| 1.80 | 4/5 | −125 | 55.6% |
| 2.75 | 7/4 | +175 | 36.4% |
| 4.33 | 10/3 | +333 | 23.1% |
| 7.00 | 6/1 | +600 | 14.3% |
Two habits worth building
- •Think in percentages. A drift from 1.80 to 2.10 sounds small. In chance terms it's 55.6% down to 47.6%, and that's a serious swing in what the market believes.
- •Compare in decimal. Fractions snap to tidy numbers, so a 4.40 elsewhere shows up as the awkward 17/5. Line every price up in decimal and the best one jumps out.
