Rwanda-facing sites commonly display decimal odds. They combine the returned stake and potential winnings into one number.
Decimal-odds calculation
For a stake of RWF 1,000 at odds of 2.50, the gross return is:
1,000 × 2.50 = RWF 2,500
The gross profit before tax or fees is RWF 1,500 because the returned stake forms part of the RWF 2,500 total.
Implied probability
A simple implied probability can be calculated as 1 ÷ odds. Odds of 2.00 imply 50%; odds of 4.00 imply 25%. This does not mean the platform guarantees that probability, and the combined implied percentages across a market commonly exceed 100% because of operator margin.
Accumulator odds
Decimal prices are multiplied. Three selections at 1.50, 1.80 and 2.00 produce combined odds of 5.40. All three must normally win. A void selection may be recalculated at 1.00 according to the rules.
Changed prices
Markets move as information and demand change. Check whether the account automatically accepts all changes, only higher prices or no changes. The final accepted ticket is the record used for settlement.
Gross versus net return
Published Rwanda terms may include withholding tax and mobile-money charges. Assess the amount likely to reach the wallet, not only the prominent gross return on the betslip.
Odds are a pricing mechanism, not an investment yield. Never borrow money or increase a stake to recover a previous loss.
