What is a betting calculator?
If you’re interested in betting on your favourite sports teams online but are far from being an experienced gambler, using a betting calculator might have crossed your mind. But before you start leaning too heavily on these online apps to help support your wagering strategy, it’s worth getting to know precisely what they do, how they work, and their supposed benefits (and pitfalls).
So, first up, what exactly are betting calculators?
Well, the short answer is that they’re online tools designed to help calculate your winning potential from different kinds of bets – be it accumulators, hedging, or each way bet explained. Of course, that’s a very simplified take on what these calculators are, when in reality, there are all kinds of different apps available, each allowing you to calculate returns and profits from a whole host of wagering types.
With that in mind, it’s worth taking a closer look at the various types of calculators online, so you can get a feel for the diverse range of options available.
Types of betting calculators
To make using an online betting calculator that bit trickier, there’s no one-size-fits-all tool to assign as your go-to. Instead, you’ll need to use the right calculator for the type of wager you’re placing, with the most common variants being:
| Type of betting calculator | What is used for |
| Odds converter | This isn’t strictly a betting calculator per se, but it’s still a useful tool to get acquainted with. Odds converters allow you to quickly convert betting odds between decimal, fractional, and moneyline, perfect if you’re using a bookmaker that uses different odds formatting (say, a brand from overseas). |
| Payout calculator | The clue’s in the name for this one; payout calculators let you quickly calculate your potential winnings, based on your initial stake, the total odds, and the type of bet. You’ll be able to pre-select all these inputs to work out your total return and net profit, instantly. |
| Accumulator/parlay calculator | Accumulator (or parlay) calculators are among the most common types of calculators used in sports betting, namely because these wagers can be so tricky to keep track of. Using a calculator for accumulators lets you work out potential payouts across multiple individual bets (legs) on the same bet slip. |
| Dutching calculator | Dutching calculators are used in spread betting to enable you to win the same profit across multiple selections. You might use a dutching calculator when you believe two or more outcomes are likely, giving you the same potential returns regardless of the total odds. |
| Hedging calculator | You can use a hedging calculator to work out how much to stake on a second outcome that’s the polar opposite of your initial bet. These calculators are ideal for maximising profit and minimising losses, meaning you’re exposed to less risk. |
| Lay bet calculator | We’re getting into the realm of serious, complicated betting calculators now, but it’s still worth knowing what lay bet tools are. These apps are designed to help you place lay bets, which you can do on qualifying betting exchanges. They’re a must-have for some types of wagers, including exchange, matched, and arbitrage bets. |
| Each-way calculator | In sports where there are multiple possible places (like golf or horse racing, for example), an each-way calculator can be used to calculate your total returns and profit. You’ll need to input your odds, stake, place terms, and result to get these figures. |
There’s a whole lot more to the term “betting calculator” than meets the eye. In reality, this is just an umbrella for a whole host of different tools designed to help you make sense of wagering strategy.
Pros and cons of using a calculator for sports betting

- Can improve bankroll management
- Can help you find low-hanging fruit
- Could remove some of the fun

How to use a sports betting calculator online (with example)
Much like in our recent guide on handicap in betting, sometimes, seeing how things work is the best way to figure it out.
So, in the same spirit, we’ve put together a step-by-step guide on using a betting calculator for sports betting. Specifically, our example is based on an accumulator betting calculator, which is one of the most prevalent types of wagering tools that most casual bettors are likely to encounter. In any case, this should give you a better understanding of how these online tools work in practice.
Step 1: First of all, you’ll need to get registered at a well-rated bookmaker in your state. Check out the banners around this page for some customised selections from our experts.
Step 2: Once you’re all set up with a bookmaker, go ahead and add your accumulator selections to your bet slip. Most bookies set a maximum of 14-20 legs, but if you’re not experienced, we’d recommend keeping your total individual bets below five.
Step 3: Now is the time to call on your accumulator calculator to work out your potential returns and profit.
Step 4: When you’ve found the right calculator, you’ll need to accurately input the following info:
- The odds for each selection
- Your total stake
- How many selections you’ve made
Step 5: Run the calculator to instantly find out your combined odds, total return, and net profit. If you’re satisfied, you can then lock in your wager back on your bookie’s website.
In reference to accumulator calculators, in particular, working out these outcomes manually can require some serious math, which does demonstrate why they’re such popular tools in the world of online sports betting.
Accumulator calculator example
Let’s say you’ve made three selections on an accumulator bet slip and wish to stake $20 (or currency equivalent). The decimal odds on each leg are:
- Team 1 to win: 2.00
- Team 2 to win: 1.80
- Team 3 to win: 2.50
Load your preferred accumulator or parlay calculator and enter this information. The calculator will instantly figure out the following:
- Combined odds: 2.00 × 1.80 × 2.50 = 9.00
- Total return: 9.00 x $20 = $180
- Total profit: $180-$20 = $160

What are the advantages and disadvantages of betting calculators?
By now, you should have a pretty decent grasp of what betting calculators are and how to use them. But the next question is, should you?
To figure that one out, we’ll be showcasing the potential benefits and pitfalls of online betting calculators, so you can decide if they’re worth incorporating into your wagering strategy.
The benefits of betting calculators
If you’ve always assumed that using a calculator for sports betting sounds smart, you’d be right. These tools can bring a ton of potential benefits, including:
- Perfect for trying different types of bets: Don’t understand exactly how a certain type of bet works? Using a calculator can ease you in and offer support as you feel your way around a new type of wagering.
- Saves time and boosts accuracy: Sometimes, you might be able to calculate your potential returns and profit yourself, but doing so takes time and can leave you exposed to human error. Using a calculator is faster and more accurate in most scenarios.
- Reduces emotion-based decision-making: Rather than taking a pot-luck approach to filling out a bet slip, a calculator can help you make informed decisions that are based on straight-up mathematics, not human emotions.
- Can improve bankroll management: Experienced gamblers will be the first to tell you that successful sports betting hinges on retaining a healthy bankroll. Betting tools are perfect for helping you manage your potential profit and returns, so you know when to push and when to hold back.
- Can help you find low-hanging fruit: Once you’ve gained some experience in sports betting, you can use calculators to test out different combinations and strategies, ultimately finding low-hanging fruit that yields maximum returns for the lowest possible initial outlay.
Are there any pitfalls associated with betting calculators?
For all the good aspects of using an online sports wagering calculator, there are a few potential drawbacks that you should consider from the outset. These include:
- Can remove some of the fun from casual sports betting: On the flipside to our earlier point about reducing emotion-based decision-making, using a calculator can remove some of the fun from placing sports bets. Some people may prefer to follow their gut when backing their favourite teams, with the potential to spoil the fun (and the thrill) by relying too heavily on calculated wagering.
- Doesn’t in any way guarantee that you’ll win – or make a profit: It’s worth remembering that calculators do not guarantee that you’ll win a bet, or that you’ll make the profit you were expecting. That’s why you’ll often see reams of small print accompanying these tools online.
- Still requires accurate data entry: Sure, online betting tools can help to remove human emotion and error from your wagering strategy, but they still rely on accurate data entry. If you input a single digit wrong, it could cost you dearly, so be sure to double-check all those entries.
