CALCULATION METHODOLOGY
The formulas are part of the product.
Every EVBet result is designed to be reproducible with a basic calculator.
01
Expected value
EV equals win probability multiplied by potential profit, minus loss probability multiplied by the stake. EV ROI divides that result by the stake.
02
Parlay assumptions
Parlay decimal odds are multiplied. Estimated leg probabilities are multiplied only under an independence assumption. Correlated selections require a model beyond the MVP calculator.
03
Rounding
Calculations retain full numeric precision internally. Monetary results display two decimal places, percentages display two decimal places, and converted American odds display as whole numbers.
