What does 8-1 odds pay? A data-driven guide for tech-savvy bettors

Hey there fellow tech and data nerd! As gambling and sports betting continues going mainstream in the digital era, more mathematically-inclined folks like us are getting into it. But for beginners, understanding how betting odds and payouts work can be confusing.

As your resident tech geek data analyst, let me walk you through exactly how to calculate winnings on 8-1 odds bets. I‘ll also dig into the data on why 8-1 represents a longshot, optimal betting strategy, and some legendary longshot winners that paid out huge at 8-1.

Grab some coffee, fire up your spreadsheets, and let‘s crunch the numbers!

Demystifying betting odds

Before I get into the nitty gritty details on 8-1 specifically, it helps to cover some betting odds basics first as a refresher.

Odds represent the implied probability of an outcome happening. Bookmakers use them to set lines on events that balance potential payouts against actual outcomes. This allows them to turn a profit regardless of the result.

Common formats for displaying odds:

• Fractions e.g. 8/1, 9/2
• Decimals e.g. 9.00, 4.50
• Moneyline e.g. +800, -125

Fractional odds (common in UK/Ireland) show potential profit first, then stake amount.

• 8/1 means for every $1 staked, a winning bet will profit $8

Decimal odds (common in Europe/Australia) represent total payout including your stake.

• 9.00 odds returns $9 on a $1 bet – $1 was your stake, $8 is profit

Moneyline odds (common in US) show profit only relative to $100 stake.

• +800 odds means $100 bet profits $800 if it wins

Now that we‘ve got the basics down, let‘s move on to calculating payouts and optimal strategy specifically for 8-1 odds bets.

How to calculate payouts on 8-1 odds

One of the most common questions from beginners is "How much will I win if I bet on 8-1 odds and get it right?"

Let‘s walk through the payout calculations step-by-step:

The formula for calculating payout on fractional odds bets is:

(Odds x Stake) + Stake

So for an $10 wager at 8-1 odds:

(8 x $10) + $10 = $80 + $10 = $90

For a £20 bet at 8-1:

(8 x £20) + £20 = £160 + £20 = £180

And for a €50 bet at 8-1:

(8 x €50) + €50 = €400 + €50 = €450

As you can see, the payout on a winning 8-1 bet is simply 8 times the original stake, plus the stake itself returned. This formula works consistently regardless of how much you bet at fixed 8-1 odds.

Let‘s look at some more examples across various bet sizes:

Stake	Odds	Profit	Payout
$10	8-1	$80	$90
$50	8-1	$400	$450
$100	8-1	$800	$900
$500	8-1	$4,000	$4,500

Now you have the tools to calculate the payout on any 8-1 odds bet, no matter how small or large your wager.

Why 8-1 odds represent a longshot

In betting terms, 8-1 odds imply that the selection in question is relatively unlikely to win.

Approximately 1 out of 9 times, the 8-1 horse, team or outcome would be expected to come first based on its implied probability.

We can calculate the implied win probability as:

1 / ( Odds + 1 )

So for 8-1 odds this gives us:

1 / (8 + 1) = 1/9 = 11.1%

This means out of 9 races or matches, the 8-1 selection would only be projected to win once.

Clearly these are pretty long odds, indicating the 8-1 pick is a pronounced underdog against its competition. 8-1 odds represent much less likely outcome than something with even money (1-1 or 2-1) or shorter (5-1 or less) odds.

For some context, here‘s how common 8-1 odds compare to other benchmarks:

Odds	Implied Probability
1-1 (Evens)	50%
2-1	33%
5-1	16.7%
8-1	11.1%
10-1	9.1%
16-1	5.9%
25-1	3.8%

As you can see, the higher the first number in fractional odds, the lower the implied chance of that outcome actually occurring.

But should the longshot 8-1 selection manage to defy those odds and win, the bettor receives a sizable payout as a reward for taking the risk.

In which betting markets might you see 8-1 odds?

Now that we understand 8-1 odds represent a longshot pick, in which sports or betting markets are we most likely to come across these underdog odds?

Horse racing

It‘s common to see odds of 8-1 or longer on races with a clear favorite. The longshots will be given chances of 10% or less.

NFL futures

Trying to predict season win totals or championship winners well in advance produces plenty of longshot odds. Backing underdog teams at 8-1 or greater is common.

NBA player props

For scoring, rebound, or assist props on role players or non-stars, books will offer longer odds in the 8-1 to 20-1 range.

MLB division winners

A popular futures bet is picking division winners before the MLB season. Non-contenders often receive odds of 8-1 or higher.

NHL Stanley Cup

In any given NHL season, the perceived top 4-5 teams often dominate the Cup odds. Longshots down the board sit at 8-1 or upward.

Election betting

In races with an clear polling leader, the longshot underdogs may be priced at 8-1 odds or better.

Now let‘s look at some real-life examples of teams, players and horses that were available at 8-1 odds before pulling off big upsets.

Notable longshot winners at 8-1 odds

Leicester City

The Foxes were 5000-1 and 8000-1 longshots in betting futures to win the 2015-16 English Premier League title. After an improbable season, Leicester City won as 8-1 odds underdogs on the final day. Bettors who took the early odds won huge.

Mine That Bird

This unheralded gelding won the 2009 Kentucky Derby at 50-1 odds. But he closed at 8-1 odds on race day after heavy betting support. ‘Mine That Bird‘ paid out $103.20 on a $2 bet.

Buster Douglas

Heading into his 1990 heavyweight title fight vs Mike Tyson, Buster Douglas was a 42-1 underdog. One week prior he was 8-1, before Tyson backers bet the odds down. But Douglas scored a historic upset, paying out massive returns for those who bet the 8-1 odds.

New York Giants

In Super Bowl XLII, the Giants upset the previously unbeaten New England Patriots as +700 underdogs. Bettors who took the Giants at early 8-1 odds to win the Super Bowl were handsomely rewarded.

Joe Flacco

The Baltimore Ravens QB won Super Bowl MVP in 2013 at 8-1 odds, considered a longshot against big name QBs like Peyton Manning and Tom Brady who were vying for the same award.

Hopefully these real-world examples illustrate how betting on 8-1 chances can produce huge payouts, even if they win far less often than shorter odds wagers.

Betting strategy and tips for 8-1 longshots

Now that you understand how to calculate payouts on 8-1 odds and the lucrative upside, let‘s talk strategy. Here are my top tips for betting on 8-1 chances while managing risk:

• Set a strict budget for lower-probability longshots and exotics. Never wager more than you can afford to lose.

• For parlays, teasers and in-game props, sprinkle in some 8-1 legs. This provides a riskier bet with massive upside.

• Hedge by also betting on the favorite in that same event. Lower potential payout but guarantees a smaller return.

• Allow time for 8-1 odds to increase. Bet closer to the event once they potentially drift out to 10-1 or 12-1.

• Shop for best odds across multiple sportsbooks. Even slight differences of 7-1 vs 8-1 odds matter in the long run.

• Purchase betting insurance if available – refund losing 8-1 bets if your selection finishes 2nd or 3rd.

• Don‘t go overboard chasing low-chance upsets. Weight your betting portfolio toward solid +EV bets.

Final thoughts on 8-1 longshot odds

Hopefully this deep dive into how 8-1 odds work, longshot probability, payout calculations, and optimal strategy gives you the tools to bet smarter. Just remember, while winning longshot wagers produce a rush and huge returns, they do so infrequently.

The key is balancing such bets with plenty of safer wagers on shorter odds. Take the occasional calculated risk on an 8-1 underdog, but bet responsibly and never more than you can afford to lose.

Now get out there and put your newfound expertise on 8-1 payouts to work (hopefully)! Wishing you nothing but winning tickets. Just be sure to buy me a beer if you score big on one of these longshots thanks to my guidance.
