Black Scholes Model & Option Pricing Method

The Black-Scholes model calculator is a tool for pricing options used to calculate the theoretical value of an option, as well as to find the optimal price for an option..

  • The Black-Scholes model is used to price both call options and put options.  A call option gives the holder the right to buy the underlying asset at the strike price, while a put option gives the holder the right to sell the underlying asset at the strike price. The model can be used to find the theoretical value of either type of option.
  • The model can also be used to find the optimal price for an option. The optimal price is the price that maximizes the option’s value.

How Can I Use Black-Scholes Option Calculator?

The Black-Scholes options calculator is a tool that can be used to calculate various option pricing, including the fair value of an option. The calculator can be accessed above for free.

The importance of the Black Scholes calculator is it turns stock options from a pure speculative gamble, into more of a science by using a mathematical equation and formula.

To use the Black-Scholes calculator to get the valuation of stock options, such as call and put options, the user must input the following key pieces of information information: 

  • Step 1 – The current fair market stock price, or current share price – the price of the underlying stock shares or asset
  • Step 2 – Enter the options strike or exercise price of the stock option contract for the option holder
  • Step 3 – The “expiry time to maturity” in the drop down menu, option expiration date, or time until expiration
  • Step 4 – The dividend yield of the underlying stock
  • Step 5 – The expected annualized volatility for options or stock (volatility skew)
  • Step 6 – The current risk-free interest rate

With this information, the Black Scholes calculator will then do the calculation for the call price for stock options, as well as the put option price.  

An Example of How To Calculate using the Options Pricing Model

To figure out the value of options with the Black Scholes calculator, you just need a few pieces of information. Let’s say you’re looking at an option with these details:

  • The current stock price is $200.
  • The option’s strike price is $210.
  • The option lasts for 6 months.
  • The stock’s expected to give dividends at a rate of 0.5%.
  • The stock’s ups and downs (volatility) are about 15%.
  • And the safe bet (risk-free interest rate) is 2%.

Here’s how you’d use the calculator:

  1. Type in the stock’s current price, like $200.
  2. Put in the price you can buy or sell the stock for with the option (strike price), here it’s $210.
  3. Tell the calculator how long until the option expires, so for us, that’s 6 months.
  4. Add the safe bet rate, which is 2% here.
  5. Let the calculator know how jumpy (volatile) the stock is, which we’ve got as 15%.
  6. Lastly, share the dividend rate, which is 0.5% for this stock.

Once you feed in these details, the calculator does its magic and tells you the option’s worth. For this example, it might say the call option (the right to buy) is worth around $12 and the put option (the right to sell) is around $5. This helps you decide if the option is a good deal or not!

The Black-Scholes Formula

The Black-Scholes option pricing method and formula is as follows:

Black Scholes Formula Equation
Black-Scholes Formula Equation

Where:

  • N = CDF of the normal distribution
  • St= current share price
  • K = exercise or option strike price
  • r = risk-free interest rate
  • t = option expiration date
  • σ = annualized volatility of the asset

The Black Scholes call option formula is a tool that financial market traders use to determine the fair market price of a call option. 

The formula takes into account the current price of the underlying asset, the strike price of the option, the time to expiration, the volatility of the underlying asset, and the risk-free interest rate. By inputting these values, the trader can see how the market price of the call option will change in response to different market movements.

The Black-Scholes call option formula is calculated by multiplying the stock price by the cumulative standard normal probability distribution function.

Brief Overview of The Black-Schole Model

The Black Scholes calculator uses a mathematical model and tool for options traders for pricing stock options. The model was first published by Fischer Black and Myron Scholes in 1973 in the paper “The Pricing of Options and Corporate Liabilities“. The Black-Scholes pricing model is used to calculate the theoretical price of an option. The model takes into account the following factors:

  • The price of the underlying asset
  • The strike price of the option
  • The time to expiration of the option
  • The volatility of the underlying asset
  • The risk-free interest rate

The Black-Scholes calculator and pricing model is a powerful tool for pricing options. The model is used to calculate the theoretical price of a call option, calculating the theoretical price of a put option by using put-call parity.

What is The Black Scholes Model?

The Black-Scholes-Merton model, called the Black-Scholes equation, is a powerful tool for pricing options.  The formula can estimate the price projections of put and call options.  The reason this model is so famous is because it was the initial equation that was widely accepted as a mathematical formula to price options.

Calculator

Following the introduction of the black-scholes model, there was a huge increase in the awareness and trading of stock options. 

Stock option trading was not common until after the introduction of this model, which helped legitimize stock option trading.

Today, options traders and hedgers alike still use the Black-Scholes models and similar variations to reduce the risks associated with the volatility of options trading.

The Black Scholes calculator uses a log-normal distribution probability to account for the volatility of the underlying asset.  This is based on the Brownian motion theory that asset prices follow the behavior of organic movement in Brownian motion.

  • The Black-Scholes model is a mathematical model of a financial market in which prices fluctuate. 
  • It is used to calculate the theoretical value of options, which are contracts that give the holder the right to buy or sell an asset at a specified price within a specified time period. 
  • The model was developed by Fischer Black, Myron Scholes, and Robert Merton in 1973 and is still used today.

What is the Black-Scholes equation used for?

The Black-Scholes equation is used to calculate the price of a European call or put option. The equation takes into account the underlying asset price, the strike price, the volatility, the time to expiration, and the risk-free interest rate.

How do you calculate Black-Scholes value?

The Black-Scholes model is a pricing model for financial derivatives that is used to calculate the theoretical value of an option. The model takes into account the time to expiration, the volatility of the underlying asset, the interest rate, and the dividend yield. The model is used to determine the fair value of an option, which is the price that would be paid if the option were to be traded on an exchange.

The Black-Scholes Equation Model Assumptions

The model can also be used to calculate the theoretical value of other financial instruments, such as futures contracts and swaps.

The model can be used to price both call and put options. A call option gives the holder the right to buy the stock at a certain price, while a put option gives the holder the right to sell the stock at a certain price.

  • The models assume that the market consists of two types of securities: stock and options
  • The model assumes that the market consists of two types of investors: speculators and hedgers.
  • The model assumes that all investors have the same information about the market and the same expectations about future prices.
  • That stock price follows a geometric Brownian motion with constant drift and volatility.
  • The stock pays dividends at a continuous rate of return, and the options are European-style options. 
  • The model further assumes that the market is efficient, meaning that prices reflect all available information.  There are no arbitrage opportunities.
  • The model assumes that prices are continuous and that there is no limit to how high or low they can go.
  • The Black Scholes calculation assumes that investors can borrow and lend at the risk-free interest rate, and that the risk-free interest rate is constant.
  • The model assumes that there are no transaction fees, trading costs, or taxes.

Assumptions and limitations of the Black Scholes Model

Hands presenting a calculator

The Black-Scholes model is a powerful tool for pricing options, but it has its limitations. 

  • First, the model assumes that the market is efficient, which is not always the case in real life. 
  • Second, the model assumes that stock prices follow a geometric Brownian motion, which is not always the case either. 
  • Third, the model does not take into account the effects of dividends. Finally, the model is only valid for European options, and not for American or other types of options.  The reason is, American options can be called prior to expiration.

Some even claim that the Black-Scholes equation was the mathematical justification for the market downturn and trading that plunged the world’s banks into a catastrophic market crash.

Extensions of The Black-Scholes-Merton Model

The models were first formulated by Fischer Black and Myron Scholes, the economists who created the model and formula.  This followed by Robert Merton publishing his take on their model to include stochastic calculus,  This model became known as the Black_scholes-Merton Formula.

The economists would later win a Nobel Prize for their work, in 1997.
