Start by entering the odds for each selection and the total amount you want to risk. The calculator converts those prices into stake shares automatically.
The most important outputs are the stake per selection, the target gross return and the final net result after your full stake is deducted. If the net result is negative, you are forcing coverage across too much of the book at the current prices.
The dynamic row system is useful for markets with many live selections. Add or remove lines as needed and switch between decimal, implied percentage, American or fractional odds depending on the source market you are reading.
