Before I go through how to work out your 100/1 bet, I should point out these long shots rarely win. Outside of events like the Grand National, you’ll unlikely to land a 100/1 bet. Let’s keep things in perspective, even in the National, one of the most open contests in horse racing, only five runners have come home at 100/1 odds in the past 100 years.

QUICK GUIDE TO 100/1 WIN BET RETURNS

£1 @ 100/1 = £100
£2 @ 100/1 = £200
£5 @ 100/1 = £500
£10 @ 100/1 = £1000
£25 @ 100/1 = £2500
£50 @ 100/1 = £5000
£100 @ 100/1 = £10,000
The amounts above do not include returned stakes.

100/1 winning bets tend to make the news. That’s because they’re quite rare. Yes, there will always be someone who took a punt on a long shot and won. But that’s the exception and not the rule. However, if you are one of those very lucky people who back and wins with a 100/1 shot then this is how to work out your bet.

EXAMPLE 100/1 BET (WIN)

A £1 winning bet at odds of 100/1 will payout £100, plus your £1 stake is returned. If you place more, the returns are increased by the amount you bet. So a stake of £2 will return £200 back (plus £2 stake). A winning bet of £50 will net you £5000 plus your £50 back. All you have to do is multiply the first number by the amount you’ve wagered.

The first number (100) is the amount you’ll win from wagering the second number (1). So for every £1 or \$1 or €1 you spend, you will win 100 back. It really is that straightforward.

Only a few sports will have odds as large as 100/1, and you’re most likely to see them in horse racing events like the Cheltenham Gold Cup or Grand National. Occasionally, you might see Everton priced up as a 100/1 shot to win the Premier League title. Famously in 2016, Leicester City won the league at the ridiculously odds of 5000/1.

In 2009 Mon Mome won the Grand National for trainer Venetia Williams. An extraordinary feat but also one that hadn’t happened since 1967, when Foinavon romped home.

I’ve added a payout guide below for some common bets placed at 100/1.

EXAMPLE RETURNS

100/1 WIN BETS

£1 @ 100/1 = £100
£2 @ 100/1 = £200
£5 @ 100/1 = £500
£10 @ 100/1 = £1000
£25 @ 100/1 = £2500
£50 @ 100/1 = £5000
£100 @ 100/1 = £10,000

EXAMPLE 100/1 BET (EACH WAY)

In the context of long shots, an each-way bet is a better one to consider. Depending on the bookmakers, those payout odds vary. So we will assume for the purposes of this article that it’s a quarter odds.

A ‘Place’ or ‘Each-way’ option means you are backing your horse/team/player to both win and place. If they finish in either 2nd, 3rd or even 4th & 5th place (depending on the bookmaker and race), you may still get some money back.

However, this also doubles your stake. That’s because you’re betting on a win AND on a place. So a £1 bet will now become £2. You are putting £1 on the Win and another £1 on the Place.

If you win you’ll get your £100 (Win bet) + £1 (Stake) + £25 (Place bet at 1/4 odds) + £1 (Stake) so you will end up with £127 in your pocket. If they do not win but place, you will only get back £25 (Place bet at 1/4 odds) + £1 (Stake) = £26

So there you have it, 100/1 explained in simple terms. You can also check out my payout guide below for the potential returns on an each-way bet placed at 100/1. However, you can also use our online bet calculator to work out other odds and stake combinations. You can also check out our 50/1 guide here.

100/1 EACH WAY BETS (2nd, 3rd or 4th Place)

£1 @ 100/1 = £25
£2 @ 100/1 = £50
£5 @ 100/1 = £125
£10 @ 100/1 = £250
£25 @ 100/1 = £625
£50 @ 100/1 = £1250
£100 @ 100/1 = £2500

Amounts above do not include returned stakes and assume the bet is settled each way at a quarter odds.

If your each-way bet wins, you can add together the win bet column and place bet column to get the correct amount. For example, a £5 win at 100/1 pays £500 + £5 place at 100/1 pays out £125, giving you a total of £6250 plus your £20 stake is returned.
