Expected Value Calculator

Use this general EV tool when the decision comes down to cost, hit probability, and payout rather than a machine-specific meter or counter.

What You Enter

Cost to Play

Your total spend or investment for the attempt.

Win Probability

Your estimated chance of the favorable outcome.

Payout

Expected return if the play lands.

Scenario Notes

Use this for comps, promos, free-play decisions, or one-off edge spots.

Quick Example

A $100 opportunity with a 60% chance to return $200 produces a positive expected value of +$20, which is a 120% return on cost.

This is the cleanest tool for judging whether a promotion, free-play offer, or edge case is worth the time before you move into a machine-specific flow.
