18/1 Odds – How To Work Out Your Bet

You’ve had a quick look at the odds. The 18/1 offer stands out to you. Is it worth betting on? How much could you win if it comes off? Is 18/1 too much of a longshot? For the answers and much more, just read on…

I’ll start by giving you the easiest way to work out your winnings on a bet of 18/1. It’s basic maths. Take the amount you staked and the larger odds number and multiply them. So if you put £1, €1 or $1 on an 18/1 and the bet wins you will get back £18, €18 or $18. It doesn’t matter which currency you use, the results are the same.

Odds work in a way that both gives you a chance of winning but also so that bookmakers can make a profit. The smaller the odds, the more likely it is that your bet will win – in theory. The bigger the odds, the more unlikely your bet will win – again, in theory.

18/1 is very middle of the road and the likelihood that the bet will succeed depends entirely on the sport you plan to bet on. And at least it’s not as short as odds of 7/4 which really can’t net you very much at all!

If you are looking at a very large horse race such as the 2019 Grand National, which has 40 runners, 18/1 are decent odds. It puts your chosen horse in the frame as a potential winner based on all the information that the bookmakers have. Likewise for golf, or any sport that has a lot of contenders.

However, if you are seeing 18/1 in a two person sport such as boxing or tennis then it is NOT good. Odds in these types of sports should be much, much closer if the two players are equally matched.

Alternatively, if you are looking ahead to a game or a tournament and your chosen player is 18/1 to win outright, and you know they might go far, then that’s a reasonable punt to take.


£1 @ 18/1 = £18
£2 @ 18/1 = £36
£5 @ 18/1 = £90
£10 @ 18/1 = £180
£25 @ 18/1 = £450
£50 @ 18/1 = £900
£100 @ 18/1 = £1800

You could also look at the ‘Place’ or ‘Each-way’ bet. Again, the odds on which they will payout will vary between each bookmaker. For the purpose of explaining it in this instance we will say it’s a quarter odds.

The ‘Place’ or ‘Each-way’ option this means that you could still get a return on your bet even when your horse/team/player doesn’t win. However, it will still need to finish in 2nd, 3rd or 4th place in whatever competition they’re in. It’s important to remember that your stake will double as you are betting on both a win and a place. So now a £1 bet becomes a £2 bet as you’ve bet on two outcomes.

If your 18/1 bet comes in and you are a winner you will get £18 (From win bet) + £1 (From your stake) + £4.50 (From your bet placing a 1/4 odds) + £1 (From your stake). This means from a £2 ‘Place’ or ‘Each Way’ bet you’ll end up with £24.50!

If your bet doesn’t come first but does place you’ll get £4.50 (From your bet placing a 1/4 odds) and £1 (From your stake) meaning £5.50 back from £2.

Effectively thats all there is to know about calculating an 18/1 bet. However if you need more help with working out other odds then use our online bet calculator! Below is examples of some bets placed at 18/1.

18/1 EACH WAY BETS (2nd, 3rd or 4th Place)

£1 @ 18/1 = £4.50
£2 @ 18/1 = £9
£5 @ 18/1 = £22.50
£10 @ 18/1 = £45
£25 @ 18/1 = £112.50
£50 @ 18/1 = £225
£100 @ 18/1 = £450

Amounts above do not include returned stakes and assumes the bet is settle each-way at a quarter odds.
