How the converter works
Every odds format is the same number wearing a different outfit. Decimal is your total return per R1, so 2.50 returns R2.50 including your stake. Implied chance is just 1 ÷ decimal — the probability the price is built on. Fractional is the profit-to-stake ratio (decimal minus one), and American shows how much you stake to win R100 (negative) or win for every R100 staked (positive). The full breakdown of each is in odds formats, and what the percentage really means is in implied probability.
One honest note the converter can't show: add up the implied chances across a whole market and they top 100%. That surplus is the bookmaker's margin, and it's why shopping for the best price matters — a few cents compounds over a season.
Frequently asked
How do I convert decimal odds to a percentage?
Divide 1 by the decimal price and multiply by 100. A price of 2.50 implies 1 ÷ 2.50 = 0.40, or a 40% chance. The converter does it instantly for any price you enter.
What is the formula for decimal to American odds?
For a decimal of 2.00 or higher, American odds are (decimal − 1) × 100, shown as a positive number. Below 2.00 it is −100 ÷ (decimal − 1), a negative number. The converter shows both.
Which odds format do South African bookmakers use?
South African books, including Scorebet, quote decimal odds — the number is your total return per R1 staked. The converter is handy when an international tip is quoted in fractional or American format.
