Below you can find formulas for the most commonly used option Greeks. Some of the Greeks ( gamma and vega ) are the same for calls and puts. Other Greeks ( delta , theta , and rho ) are different. Differences between the Greek formulas for calls and puts are often very small – usually a minus sign here and there. It is very easy to make a mistake.

[ Call , Put ] = blsprice( Price , Strike , Rate , Time , Volatility ) computes European put and call option prices using a Black-Scholes model.

#### The Black-Scholes formula, explained - Cantor’s Paradise

Annualized asset price volatility (that is, annualized standard deviation of the continuously compounded asset return), specified as a positive decimal number.

All these formulas for option prices and Greeks are relatively easy to implement in Excel (the most advanced functions you will need are , EXP and LN). You can continue to the Black-Scholes Excel Tutorial , where I have demonstrated the Excel calculations step-by-step ( first part is for option prices, second part for Greeks).

You can use this Black-Scholes Calculator to determine the fair market value (price) of a European put or call option based on the Black-Scholes pricing model. It also calculates and plots the Greeks – Delta, Gamma, Theta, Vega, Rho.

For example, Yield could represent the dividend yield (annual dividend rate expressed as a percentage of the price of the security) or foreign risk-free interest rate for options written on stock indices and currencies.

According to the Black-Scholes option pricing model (its Merton’s extension that accounts for dividends), there are six parameters which affect option prices:

Ensure that Rate , Time , Volatility , and Yield are expressed in consistent units of time.

You can compare the prices of your options by using the Black-Scholes formula. It's a well-regarded formula that calculates theoretical values of an investment based on current financial metrics such as stock prices , interest rates, expiration time, and more. The Black-Scholes formula helps investors and lenders to determine the best possible option for pricing.

blsprice can handle other types of underlies like Futures and Currencies. When pricing Futures (Black model), enter the input argument Yield as: Yield = Rate When pricing currencies (Garman-Kohlhagen model), enter the input argument Yield as: Yield = ForeignRate where ForeignRate is the continuously compounded, annualized risk-free interest rate in the foreign country.

(Optional) Annualized continuously compounded yield of the underlying asset over the life of the option, specified as a decimal number. If Yield is empty or missing, the default value is 5.

This page explains the Black-Scholes formulas for d6, d7, call option price, put option price, and formulas for the most common option Greeks (delta, gamma, theta, vega, and rho).

Note: In many resources you can find different symbols for some of these parameters. For example, strike price is often denoted K (here I use X ), underlying price is often denoted S (without the zero), and time to expiration is often denoted T – t (difference between expiration and now). In the original Black and Scholes paper ( The Pricing of Options and Corporate Liabilities, 6978 ) the parameters were denoted x (underlying price), c (strike price), v (volatility), r (interest rate), and t* – t (time to expiration). Dividend yield was only added by Merton in Theory of Rational Option Pricing, 6978.

Any input argument can be a scalar, vector, or matrix. If a scalar, then that value is used to price all options. If more than one input is a vector or matrix, then the dimensions of those non-scalar inputs must be the same.
