ROI Calculator: Calculate the Return on Investment of Your Sports Bets

Whenever we make an investment in a world outside of betting on sports, we are doing it to try and make a profit and essentially gain a return on that investment.

Well, it is the same when it comes to sports betting. You are placing money down on something and expecting and hoping to get some back in return. This guide will explain how you can use a sports betting calculator to work out your potential returns when betting on sports.

What Is An ROI Calculator And Its Purpose Of Use?

You will have seen ROI quite a lot already in this guide, but do you actually know what it means?

ROI stands for Return on Investment, and although you might not think that sports betting is an actual investment, it is. When you make a financial investment in the real world, there is no guarantee that a profit will be made. It is exactly the same in sports betting.

ROI is a way of working out what your expected loss or profit would be when placing a bet. In basic terms the ROI is the amount you can expect to return from your initial investment. It is based on the price and whether or not your bet is a success, do not always assume your bet will win because there is a good chance that bet will go to zero.

Our ROI calculator has been designed to calculate the expected profit or loss of each bet and it is simple to use. For the ROI sports betting calculator to work, you will need to input the amount you wish to bet, the odds of the bet and estimated probability of that bet winning.

Once that has all been inputted correctly, the ROI betting calculator will calculate the implied probability of that bet being successful, the expected monetary return and the ROI as a percentage of the amount you have staked.

How To Calculate Your ROI

Using the ROI calculator is very straightforward and so is working it out manually. Most online betting calculators are there to cut out any stress and complications, but this one is quite easy to follow.

Here are the main steps for calculating your ROI if you do not want to use an ROI sports betting calculator:

Implied Probability

Implied Probability CalculationFormula
Implied Probability For Fractional OddsDenominator / (denominator + numerator) x 100
Implied Probability For American OddsOdds / (odds + 100) x 100
Implied Probability For Decimal Odds(1 / odds) x 100

Winnings

After working out your implied probability, you will then need to calculate what your winnings would be. For this equation, you will need to convert your odds to decimal if you are not already using them.

For example, if you are using -110 American odds you the decimal odds would be 1.9091. The formula would then be:

Winnings = Decimal odds x Chances of winning / 100 x bet amount 

ROI

The formula used to work out the ROI on your sports bet will include your previous calculations. The formula would be:

ROI = Winnings / Bet -1

If you find this section too confusing, then that is what our ROI sports betting calculator has been designed for. If you do not want to work out the calculations manually, then type in the relevant information into the calculator and let it do all the hard work.

Main Purpose Of An ROI Calculator

An ROI sports betting calculator is designed to give you an idea of what you can expect to win in terms of profit.

You will have most of the information needed already, so once the calculations are done you will receive the implied probability and the expected return.

The final part of the calculation is probably the most important. Once the potential winnings have been calculated you will also see that turned into a percentage of how much of your stake you will see as a return on your investment.

Using an ROI sports betting calculator is a good way of monitoring your bankroll. In sports betting, the bankroll is an amount of money that the bettor has placed away solely just for using to bet with. It is their betting capital and helps them choose the size of bets and manage the risk. By using an ROI calculator, you can keep a close eye on your bankroll and ensure you don’t over spend.

What Does Yield Mean In ROI Sports Betting?

Yield is just as important in sports betting as ROI. Yield allows you to see how you are doing on average with your bets.

In sports betting yield has its own definition. It is defined as the profit or loss for the total amount invested.

Calculating your yield is quite simple:

[(Amount of winnings - amount of bets) / amount of bets] x 100%

By following this formula you will see your average win per bet.

Here is an example of working out your yield:

MatchOddsBet (£)OutcomeWin (£)Gain (£)
Arsenal vs Liverpool1.2510Win12.502.50
Everton vs Luton Town2.5010Lose0-10
Tottenham Hotspur vs Chelsea2.2010Win22.0012.00
Manchester City vs Aston Villa1.6010Win16.006.00
Bayern Munich vs Borussia Dortmund1.4010Win14.004.00
Total5064.5014.50

Your yield after those five bets would be:

[(£64.5 - (£50) / £50] x 100% = 29%

This then works out at you winning an average of 29% per bet for those five selections.

How To Use Our ROI Sports Betting Calculator

The ROI betting calculator is quite simple to use once you know how much you are willing to stake and you have collected your odds from the UK’s best bookmakers.

Once you have inputted the relevant information - betting amount, estimated probability and your odds - you will then press calculate.

Once the calculations are complete you will receive the implied probability of it being a winning bet. You will then see how much you would actually win before seeing the final section labelled ‘Return’.

The return section is your ROI. This will be the expected profit or loss displayed in a percentage of your bet amount.

Here is a brief step-by-step guide on how to correctly use our ROI betting calculator. Have a few test runs with it before trying it out for real.

  1. Open up our ROI calculator
  2. Choose which format you wish to use - Fractional, Decimal or American odds
  3. Enter the amount you wish to stake on your bet
  4. Type in your estimated probability of winning
  5. Input your selected odds
  6. Press Calculate
  7. You will then receive a breakdown that includes the implied probability, your winnings and your return as a percentage
