Price Probability Calculator

This calculator calculates the probability that an asset’s price will be above a given level at a given point in the future, based on the asset’s current price and volatility.

For example, if current stock price is 50 and volatility 20%, it answers this kind of questions:

What is the probability that the stock will be above 60 / below 45 / between 55 and 60, two months from now?

Chart shows how the probabilities change with different inputs, such as start price, volatility, interest rate, or period length.
