What are sports betting odds?
Sports betting odds are numbers that determine the chances or probability of winning a prediction and the amount of money you will get.
Betting odds are determined by the volume of bettors, the popularity of the team, player, or tournament, and the bookmaker’s profit margin.
Types of sports betting odds
Fractional odds
These are numbers displayed in fraction format, showing the probability and the amount of money a stake can win.
Fractional odds are quick to understand the amount and probability you are about to win. For example, 3/1 means the bet earns 3 shillings for every 1 shilling stake. If you stake UGX 100, you will win UGX 300. This represents an unlikely scenario: you will win, or, as commonly referred to, “odds-against” bets.
3/5 means you win UGX 3 for every UGX 5 staked, and 1/1 means you win UGX 1 for every UGX 1 staked.
In the case of ⅗, or an “odds-on” bet, it is a scenario showing a high probability of winning the bet, while in the 1/1, or 50/50, even bet, requires a bettor to double stake for wins.
Decimal odds
These are common betting odds presented in decimal format to display a quick view of the probability and winnings.
In decimal odds, the higher the number, the higher the potential winnings. For example, odds of 2.0 mean you win UGX 200 if you stake UGX 100, and odds of 3.5 mean you win UGX 350 with the same stake amount.
At SportPesa Global, we use decimal odds, making it easier for bettors to understand and predict match probabilities and calculate stake winnings.

How sports betting odds work (maths and probability)
Understanding betting odds and probability is essential for all bettors to make huge returns on their stakes. Betting odds are provided on every match event and market, and it is up to the bettors’ choice to determine the winning odds predictions.
The odds show the percentage of winning and the probability of winning return on stake.
For decimal odds, the percentage of winning is calculated by multiplying the decimal by 100%. For example, 1.2 × 100% gives you a winning percentage of 120%. That is, if you stake UGX100, you will win UGX100x120%, or UGX120.
The probability of this odd winning is calculated by dividing 100 by the odd. For instance, 100/1.2, which is 83%. This shows the event is much more likely to occur.
A decimal odd of 2.0 shows a 50% probability of the event happening.

How Sports betting taxes work
Sports betting taxes target both the punter or bettor and the sports betting app. At SportPesa Global, taxes applied are excise duty charged on stakes and withholding tax on winnings.
Withholding tax
When you win any bet, a 20% withholding tax is charged, and the amount is withheld from your winnings. Afterwards, you will not need to pay any other tax on the remaining amount won.
Excise duty
This is charged on the stake amount. When you place a bet, 15% tax is on the money placed on the bet. We pay the tax as part of our total gross gambling revenue (GGR) structure.
This tax is factored into the betting odds and returns provided to bettors.
