Why expected value, not just profit chance
Most calculators stop at the payoff chart and a probability. But a trade that wins 85% of the time can still lose money overall if its losses are big enough. Expected value puts the size of wins and losses together with how likely each is. It turns on one question: is the stock moving more or less than the options are pricing in? Enter the stock's realized volatility and the calculator answers it.
Questions
How does an options profit calculator work?
It adds up what each option is worth at expiration for every possible stock price, then subtracts what you paid or adds what you collected. That gives the payoff line on the chart, the max profit and loss, and the breakevens where the line crosses zero.
How is profit chance calculated?
From implied volatility: the calculator assumes the stock's price at expiration follows a lognormal distribution as wide as option prices imply, and adds up the probability of every price where the trade makes money.
What is expected value for an options trade?
The average profit or loss per contract across all the outcomes, weighted by how likely each one is. This calculator uses the realized volatility you enter, so it shows what the trade makes on average if the stock keeps moving the way it has been.
Is this financial advice?
No. It's a calculator. It shows the math for the numbers you enter and doesn't recommend any trade.
