Horse racing betting can be exciting — but it can also be confusing if you’re new. Terms like 9/5 odds or 7/2 odds can feel like a different language. Don’t worry, we’ll break it all down in simple terms so you can feel confident placing your first bet at one of the top horse betting sites online.
What Are Horse Racing Odds?
Horse racing odds show you how much money you’ll win if your bet comes in. But they also tell you how likely the horse is to win—according to the betting market.
Odds come in fractional format (e.g. 5/2 or 9/5) or decimal format (e.g. 3.50). In the UK and US, fractional odds are most common at the track.
Horse Racing Odds Chart / Comparison
Here’s a quick horse racing odds chart showing what you win from a £10 bet (or $10):
| Odds (Fractional) | Profit on £10 Bet | Total Return |
|---|---|---|
| 1/1 (Evens) | £10 | £20 |
| 5/2 | £25 | £35 |
| 9/5 | £18 | £28 |
| 7/2 | £35 | £45 |
| 9/2 | £45 | £55 |
| 10/1 | £100 | £110 |
Tip: Multiply the second number by your bet to calculate profit. Then add your stake to get your total return. These odds you can see on the popular sites and racing apps in the UK like MrPlay, bet365, Betvictor, betfred and 10bet.
What Do 9/5 Odds Mean in Horse Racing?
9/5 odds mean for every £5 you bet, you win £9 profit. If you stake £10, you’d make £18 profit and get £28 back in total.
So if you back a horse at 9/5 and it wins:
- Bet: £10
- Profit: £18
- Total Return: £28
What Does 9/2 Odds Mean in Horse Racing?
9/2 odds mean you win £9 for every £2 bet. A £10 bet at 9/2 gets you:
- Profit: £45
- Total Return: £55
It’s a slightly longer shot than 7/2, so your payout is higher if the horse wins.
What Does 5/2 Odds Mean in Horse Racing?
5/2 odds mean for every £2 you bet, you win £5 profit. A £10 bet gives you:
- Profit: £25
- Total Return: £35
Horses priced at 5/2 are usually considered strong contenders.
What Does 7/2 Odds Mean in Horse Racing?
7/2 odds translate to £7 profit for every £2 staked. A £10 bet at 7/2 would give:
- Profit: £35
- Total Return: £45
Still not a favourite, but not a huge outsider either—what you’d call a mid-range pick.
How Are Racing Odds Determined?
Horse racing odds are determined by:
- Bookmakers’ analysis: past performance, jockey, trainer, distance, track conditions.
- Public betting: as more money is placed on a horse, its odds shorten (drop).
- Starting price (SP): the odds at post time are known as the official SP.
So odds can change right up until the race starts.
What Are the Best Odds in Horse Racing?
“Best odds” depend on your strategy:
- Lower odds (like 2/1 or even 6/4): safer bets, but smaller payouts.
- Higher odds (like 10/1 or 25/1): bigger payouts, but more risk.
Each-way betting is popular on longshots, as it pays out if the horse places, not just wins.
Tip: Use “best odds guaranteed” offers from UK bookies like Bet365, Coral or Paddy Power. If the odds go up after you bet, you get paid at the higher price.
Once you get used to fractional odds, it all makes sense. Use the odds to spot value, calculate your returns, and understand the risk before you place a bet.
And remember, odds = probability + payout. Use that to your advantage.
What are fractional odds in horse racing?
They show how much you win compared to your stake. Example: 5/1 means £5 profit for every £1 bet.
Can I convert fractional odds to decimal?
Yes! Just divide the first number by the second and add 1. Example: 5/2 = 2.5 + 1 = 3.5 (decimal odds).
What’s a longshot in horse racing?
A horse with high odds—like 20/1 or 33/1. Less likely to win, but pays big if it does.
Do odds change before the race?
Yes. Odds shift as more bets are placed and new info comes in (like a jockey change or rain).
