How to calculate delta depends on the field, but the core formula is always new minus old or final minus initial. In general math and science, delta is calculated as Δ = final value - initial value. For example, if temperature goes from 20 degrees to 30 degrees, ΔT = 30 - 20 = 10 degrees. If a stock price goes from $50 to $45, delta is $45 - $50 = -$5. In options trading, delta is more complex and is calculated using the Black-Scholes model or other pricing models. It is the first derivative of the option's price with respect to the underlying stock's price. You do not usually calculate it by hand. Instead, trading platforms show it. Conceptually, call delta is between 0 and 1, and put delta is between -1 and 0. For a quick estimate, you can calculate delta as change in option price divided by change in stock price. For example, if a stock moves $1 and the option moves $0.60, delta is approximately 0.60. In chemistry, delta for enthalpy is calculated as ΔH = H products - H reactants. In physics, velocity change is Δv = v final - v initial. So the universal method is to identify your starting and ending values and subtract. For advanced applications like options, use an options calculator where you input stock price, strike, time, volatility, and interest rate.
