Here at PromoGuy US, we’ve got a diverse selection of betting calculators that are designed to enhance your overall experience when gambling online. And you can access all of them right here on this page.
Our range of calculators cover multiple bet types and experience levels. Our moneyline calculator can help you get to grips with the basics, whereas our arbitrage and Kelly Criterion calculators are perfect for the more experienced sports bettors among you.
Above all else, calculators make life easier for you, so they have way more advantages than disadvantages. Still, I have summarized the main pros and cons of using these helpful tools below:
Pros & Cons

Some calculators are complex and not beginner-friendly
What is a betting calculator?
As you have seen, there are many different types of bet calculators and each one is slightly different. Where they differ from normal calculators, is that they are custom-built to fit the formula required for their purpose.
For example, the straightforward moneyline calculator is designed to show you your potential profit and payout for a given stake at the odds being offered. At a more advanced level, an arbitrage calculator will calculate the ROI on two or more outcomes across different
betting apps, based on your stake and the odds.
Designed to make life easier for you
At the end of the day, all betting calculators serve the same purpose - to make your life easier and enhance your overall experience. Even with a basic bet, it can be tough to calculate the expected payout and profit in your head.
But our bet calculators can do this for you in a matter of seconds, regardless of whether you’re looking to implement a complex strategy, or you just want to know how much you stand to win with a $25 stake on the Dolphins this weekend.

The best betting calculators at PromoGuy US
Keen to know more about what betting calculators we have available to you here at PromoGuy? Below, you can find more details about each one to help find what you are looking for.
The staples - Our three must-use betting calculators
Whether you are a complete beginner, a casual bettor, or an experienced high roller, you should use these calculators for every bet you place:
Odds Converter
- Converts the odds from one format to another. Alongside the converter, you’ll also find an explanation of how bookies determine their odds, to give you a greater understanding.
Bet Return Calculator
- This shows the total expected return and profit for your bet. To use it, you just need to enter the odds and your total stake.
No Vig Calculator
- The odds offered by the sportsbooks are not the “true” odds. They add something called the “vig”, which is effectively a commission so they can protect their profits. This tool allows you to see the “real” odds that haven’t been manipulated by the bookies.
Specific bet type calculators
First of all, here are some of our calculators that are designed to help you determine your expected return and profit for specific bet types:
Moneyline Calculator
Your bread and butter, this is the basic calculator that gives you the answer for a straight bet, on a team to win for example.
Parlay Calculator
Calculates your potential payout for a combo bet with at least two selections. All selections need to win for your wager to pay out.
Spread Betting Calculator
A points advantage is given to the underdog while a handicap is taken from the favorite to even up a contest.
Asian Handicap Calculator
Similar to the points spread, except half and quarter points are more commonly used (e.g. +1.5 or -0.75).
Half Point Calculator
This specifically calculates the value of a half point in the points spread or Asian handicap.
Trifecta Calculator
Calculates your potential payout for a bet on the first three horses or greyhounds to place in a race.
Yankee Bet Calculator
Calculates potential return and profit for 4 selections combined into 11 equal bets.
Accumulator Calculator
Similar to a parlay, only that you make three or more selections.

Our betting strategy calculators
In addition to all of the calculators mentioned above, we also have a range of tools that have been specifically designed to help you implement the best betting strategies. Below, you can find a short explanation of each betting strategy and how our calculators can help:
Arbitrage Calculator
Arbitrage betting involves wagering on both outcomes of the same event on two different sportsbooks to guarantee a profit. Wherever possible, you would use
sportsbook promotions
to enhance this strategy by reducing cash outlay.
To use the calculator, you need to enter the odds for each outcome plus your total stake.
The arb calculator will tell you how much of the total stake you need to allocate to each bet, as well as the ROI and profit.
If it gives you a positive ROI you are guaranteed a profit. If the ROI is negative, the bet will guarantee a loss and should be avoided.
Kelly Criterion Calculator
This classic betting strategy is designed to help you manage your bankroll effectively and efficiently. To use our Kelly Criterion calculator, enter your total bankroll, odds for the event, and your win probability.
Once you've done that, our calculator will tell you how much you should ideally be looking to bet on that outcome. The aim is to get you the best expected value (EV) and profit.
Dutching Calculator
This is very similar to our Arbitrage calculator, as it helps to guarantee you a profit on both outcomes of the same event. However, it offers more flexibility as you can calculate it on your total combined stake (like arb betting) or based on the stake for your first bet.
If you choose the latter option, our Dutching calculator will show you how much you need to bet on your other selections.
Hedge Calculator
Hedge betting involves minimizing or eliminating the risk of your main bet by backing one or more opposing outcomes. It is similar to Dutching and arbing, only that you don’t necessarily have to guarantee a profit with hedging, often you are simply reducing the risk.
While this does leave you with the possibility of losing, the predicted profits can be much higher than with Dutching and arbitrage bets.
Betting calculators - Conclusion
As human beings in the modern world, we’re always looking for tools and hacks to make our everyday lives easier. And the first thing you can do is to sign up with a selection of the
best betting sites
to make sure that you always have a range of competitive odds to choose from.
Next, select the right calculator for the type of bet you want to place, enter the numbers, and the calculator will give you the result at the click of a button. As you can see, you don’t need to endlessly crunch numbers to calculate your expected betting profits, our betting calculators can do it for you.

Betting calculators FAQ
❓ How do I calculate my bet winnings?
That depends on which type of odds format you prefer to use, as the formula is slightly different. To make it easy, we recommend using one of our betting calculators here at PromoGuy.us. As well as a straightforward odds converter, we also have bet and strategy-specific betting calculators for more advanced users.
🔎 What is the formula for calculating bet winnings?
There are various formulas for calculating your winnings depending on the odds format. Decimal odds are by far the easiest to work out, as you simply need to multiply your stake by the odds to calculate your total payout. You can then subtract your stake from the total payout to see your expected profit.
🧐 Where can I find a free betting calculator?
You’ll find more than 15 free bet calculators here at PromoGuy.us. In addition to standard odds and returns calculators, we also have calculators for advanced betting strategies, including Dutching and Arbitrage.
