What 80/1 means
With fractional odds, the first number is what you win and the second is what you stake. At 80/1, every £1 you stake wins £80 in profit, and your stake is returned on top. Because you win more than you stake, it's an odds-against price: the bookmaker rates this outcome as less likely to happen than not.
It's read as "eighty to one".

How likely is 80/1 to win?
80/1 implies a 1.2% chance, or about 1 in 81. In other words, the bookmaker expects it to win about once in every 81 attempts. The true chance is usually a little lower than this, because bookmakers build a margin into every price.
80/1 each way
An each way bet splits your stake between a win bet and a place bet, with the place part paid at a fraction of 80/1. For a £5 each way bet (£10 in total):
| Place terms | Place odds | Returns if it wins | Returns if it places |
|---|---|---|---|
| 1/4 odds | 20/1 | £510.00 | £105.00 |
| 1/5 odds | 16/1 | £490.00 | £85.00 |
At 1/5 terms, a placed finish alone returns £85.00 from the £10 total stake, so the place part covers the whole bet with £75.00 to spare. Work out any each way bet.
If a horse at 80/1 is withdrawn
A horse priced at 80/1 being withdrawn doesn't trigger a Rule 4 deduction. The scale only applies when the non-runner was 14/1 or shorter. Work out a Rule 4 deduction.
