You can calculate the option Greek delta in Excel because it is a powerful calculation software. Don’t know how? We have come to save you. In this article, we’re going to show you the steps to calculate the option Greek delta in Excel. Let’s get started.

## What Are Option Greeks?

Option Greeks are monetary indicators of how sensitive the price of an option is to the factors that determine it, such as volatility or the value of the underlying asset. The Greeks are used in the subtlety analysis of a value or notebook of options and in the analysis of an options portfolio. Many investors view the metrics as necessary for making wise selections while trading options. There are 5 most commonly used options in Greek. There are also many other options available for Greeks.

Name | Dependent Variable | Independent Variable |
---|---|---|

Delta |
Strike Value | Value of Underlying Asset |

Gamma |
Delta | Value of Underlying Asset |

Vega |
Strike Value | Volatility |

Theta |
Strike Value | Time of Maturity |

Rho |
Strike Value | Rate of Interest |

## What Is Option Greek Delta?

Delta is a measurement of an option’s value changes in the value of the elemental asset. In other words, the option’s value will change by the itemized amount if the price of the underlying asset rises by a dollar. The formula for the **DELTA function** is:

**⍙=N (d1)**

Here, **N** is the normal distribution of the price of the share, and the formula for **d1** is

**d1=log S/K+(r+σ^2/2)T/σ√T**

Here,

**S**= Price of Underlying Asset.

**K**= Strike Price.

**σ**= Volatility.

**r**= Risk-Free Factor Rate.

The function is typically calculated as a decimal between **-1** and** 1**. **Puts** have a value of **-1** to **0**, while **Call options** can have a value of **0** to **1**. The money value is as deep as, the closer its delta is near **1 **or **-1**.

The complete average of the deltas of all the option values in a portfolio is the portfolio delta function.

Another name for Option Greek Delta is the hedge ratio. A trader can give a barrier to his position by purchasing or selling the number of itemized assets multiplied by the option’s Greek Delta if he knows it.

## Calculate Option Greek Delta in Excel: 4 Steps

To calculate the options Greek delta, you must follow simple and straightforward steps. After following the instructions, you will be able to easily calculate the delta, which will help you form a clear concept about the investment of money in the stock market.

Not to mention, we have used the ** Microsoft Office 365** version. You may use any other version at your convenience.

### Step 1: Input the Entity

- First of all, we have to enter all the entity that is related to the calculation.
- We have entered the Strike Price (k), the Time to Maturity (T), and Volatility. Risk-free factor, and Underlying Price of the Asset.

### Step 2: Calculate the Distribution

- Secondly, go to the
**C10**cell and insert the below formula.

`=(LN(B10/$C$4)+(($F$6+($F$5^2)/2))*$C$5)/($F$5*SQRT($C$5))`

Here,

**B10**= Underlying Price of the Asset.

**$C$4= **Strike Price (k)

**$C$5= **Time to Maturity (T)

**$F$5= **Volatility ()

**$F$6= **Risk-free Rate ®

The **LN function** calculates the logarithmic value, and the **SQRT function** returns the square root value of cell **C5.**

- Eventually, press
**ENTER**and drag down the**Fill Handle**tool for the other cells.

Finally, you get the distribution value like the image below.

- At this moment, move to cell
**D10**and insert the formula.

`=NORM.DIST(C10,0,1,TRUE)`

In the above formula, we have used the **NORM.DIST function**, which returns normal distribution for **Mean** and **Standard deviation**. In statistics, this function can be used for a variety of things, including hypothesis testing. The **NORM.DIST(C10,0,1, TRUE)** syntax returns the normal distribution of the cell **C10** where **0** is the mean and **1** is the standard deviation. Here, **TRUE** stands for **cumulative**.

Finally, you get the **N (d1)** value after dragging it down.

### Step 3: Evaluate the Call Option

The **Call **options are evaluated as **Call Delta**= **N(d1). ** As we calculated the **N(d1**) in the **D10:D22**, we can easily put the value in **E10:E22**. As a result, we put the value in the **E10** cell as

`=D10`

Consequently, you get the result after pressing **ENTER** and dragging it down.

### Step 4: Estimate the Put Option

The formula for the **Put **option stands for **=N(d1)-1**.

So, we move to cell **F10** and insert the formula

`=E10-1`

Here, **1** is subtracted from cell **E10**.

Eventually, hit **ENTER **and drag the same formula into other cells.

Finally, you get the outcome depicted in the image below.
