What Exactly is an ROI Sports Betting Calculator?

You may have heard of ROI, which stands for ‘Return on Investment’ and is commonly discussed in investment and business settings. Now, in sports betting, ROI is a sophisticated way of seeing what profit or loss you will face when you next decide to take a punt on a sportsbook.

With a betting ROI calculator, you’ll be able to determine 1) what your winnings would be on a given set of odds and stake, and 2) what percentage of return you can expect if you do win (the ROI bit of this calculator).

It does this first by calculating your expected winnings if the bet you wagered on wins with this formula:

Winning Amount = Decimal Odds x Probability of Bet Winning / 100 x Stake

Finally, it figures out your return by removing your initial stake and converts it into a percentage with this formula:

ROI = ((Winnings / Wager Amount) – 1) x 100

Now, our calculator goes one step further and also calculates things like the implied probability of you winning the bet. In other words, this percentage shows you how likely the sportsbook in question thinks your bet will win. This way, you can easily see if your bet is worthwhile.

Why Should You Start Using a Betting ROI Calculator?

Our betting ROI calculator gives you three results to help you understand the value of the bet and decide whether or not it’s worthwhile for you. These results include the implied probability, winnings, and return. If probability isn’t your strong point, knowing the likely winnings can help you make a decision on your bet.

It can also help you with your ROI tracking over the season or over all time to help you understand how up or down you are in terms of returns. Since our ROI betting calculator handles all the calculations for you, at the press of a button, you can quickly get the info you need, no matter where or what.

What is ROI Betting?

ROI betting is a bankroll and risk management strategy that can help you fully prepare for average outcomes. You can track the return of a bet so you fully understand how much you’ve won outside of your stakes over a period of time. You can also use the return estimation to determine whether a bet is worth the risk or not. Generally, bets with a negative ROI aren’t worth your time.

Example of ROI Betting

Let’s give you a real-world example of the ROI strategy at work. Say you want to bet on an ATP Monte Carlo matchup between Holger Rune and Grigor Dimitrov. The odds are

  • Rune to win: 4.50
  • Dimitrov to win: 1.20

You need the true probability of Rune winning since this doesn’t include the profit margin added by the sportsbook. When we use our free odds calculator, we get:

  • Rune to win: 21.05%
  • Dimitrov to win: 78.95%

Now, let’s find the ROI of betting on Rune. We set the betting amount to $100 and then entered the true probability and the original odds. Do this, and we get:

  • Implied Probability: 22.22%
  • Winnings: $94.73
  • Return: -5.27%

Since the return is in the negative, we can infer that the bet is risky. This doesn’t mean we can’t still make the bet, but since it’s a risk and the ROI isn’t likely to be there, we’d be better off lowering our stake amount.

Why Should You Track ROI When Betting?

While tracking ROI doesn’t help with the actual bet, it can help keep figures clear and understandable, making it critical for bankroll management, and therefore a very popular betting strategy. The potential return figure, as well as the generated implied probability associated with your bet, can also help you decide if you should make the bet or not. Together, these factors help you understand your betting habits on a long-term basis, to help you keep your bets within your budget.

Is ROI Tracking Possible On All Bets?

Yes, you can track ROI on absolutely any bet and on any sport out there, though our calculator is designed for single bets rather than accumulators or parlays. This doesn’t mean you can’t use it on those types of bets at all, however. Just that there are extra steps involved!

Football (Soccer)

Football (soccer) has a massive number of betting markets to bet on. From singles and parlays to even the different types of bets, there are near infinite combinations. Not to mention the fact that bet builders are usually available for football betting by the biggest sportsbooks, increasing the number of options tenfold. By using our calculator, you can work out what your total ROI is for a game (which is useful if you place multiple bets), the season, and all time.

Tennis

Tennis only has two results, but even then, there are many bet options, including time, matches, points, prop bets and more. Tennis is also narrowed into tournament-style plays, making tracking ROI easier and more effective, especially when you use our calculator. You can use it per match, per tournament, or per year, to help you understand how your bets add up over time. Since tennis is largely full of straight bets, planning out your ROI is also easier.

Darts

Darts also work in tournaments, which again means tracking your ROI on all bets from the start of the tournament to the end is much easier, especially when you use our calculator to keep track of your potential returns on a game-by-game basis. Since tournaments are contained, you’ll find it easier to track ROI properly and see a clear net profit or loss at the end of the tournament. You can even use our calculator to find the return of bets you win, which can help you with your bankroll management efforts.

Start Tracking ROI With Our Free Sports Betting ROI Calculator

You can use our free sports betting ROI calculator on any bet with any of our top-rated online bookmakers. To use it, choose the odds format you’re using (American, fraction, or decimal), how much you plan on betting (the stake), how probable you think your bet will be, and the odds of the bet you want to place. You’ll get winnings, return percentages, and implied probability when you calculate.

3 Must-Read Tips for Using Our ROI Sports Betting Calculator

Using our ROI sports betting calculator is a must if you want to add ROI tracking to your bet strategy. Our calculators handle all those pesky formulas for you to speed up your research significantly. That doesn’t mean that there aren’t some things to keep in mind. These top tips will help you get more out of our calculator and the ROI tracking approach:

Make Sure You Select the Right Odds Format at the Top

Make sure to select the odds format you’re using at the top. You won’t get accurate results if you input American odds and the calculator thinks you’re using decimals.

When In Doubt, Put the Implied Probability in the Your Probability of Winning Box

If you don’t have your own probability algorithm (most won’t), that’s okay. Instead, just put the implied probability of the bet (we recommend using our odds calculator) in the slot instead.

Be Wary of Betting on Negative Return Options

Negative return predictions based on the information you provide essentially mean that you can expect to lose money on the bet more often than not. You can still win with those bets, but they are riskier.

What Other Calculators Do We Offer?

We offer over 15 different calculators to help you with whatever your betting strategy may be. As our ROI calculator works with any type of bet or sport, it can also be used alongside any of our other betting calculators.

ROI Betting Calculator FAQs

🧐 Why do I need to add in the probability of my bet if it generates implied probability?

There are a few reasons you’ll need to add this in: 1) if you have the true probability (you can use our fair odds calculator to find this) 2) if you want to use a more trusted sportsbook’s probability result (for example, you’re betting on Stake.com for the bonus but want to use Bet365’s implied probability) 3) if your odds are boosted, you’ll want to use the original implied probability, not the boosted odds probability.

🤩 What’s a good ROI return for a bet?

Anything positive is a good ROI for a bet since it means you will be going home with more than you bet with.

👀 Is ROI the same as yield?

If you’re looking into ROI betting, you’ve likely heard of yield. Yield is simply the overall average return of each bet you’ve made overall. If it’s in the positive, it means you’ve won more than you’ve lost. If it’s negative, it means you are losing consistently and should re-evaluate your wagers or betting habits.

🏁 Can I still lose on a bet with a positive return?

Yes, you can lose absolutely any bet that you place. Positive returns simply refer to what you stand to gain if your bet does win.

💸 Can I calculate ROI with this calculator on an accumulator bet?

Yes, you’ll need to use another of our online betting calculators (either the parlay or accumulator calculators specifically) to generate the overall odds and implied probability. Once you have that, you can then take those values and plug them into this betting ROI calculator to see just what kind of return you can expect if your bet does win.
