The formula, plainly

EV = (win% × profit) − (loss% × stake). If your 55% is real, +100 pays +$10 per $100 forever; if it's really 50%, you're lighting money. The number that matters is where your win% comes from — devig the sharpest market or bring a model, then size the survivor with Kelly. The live +EV finder runs this same math across every posted price automatically.
