# How to Create Fibonacci Sequence in Excel ( 2 Easy Methods)

Today we will discuss how to create a Fibonacci sequence in Excel. Numerous mathematical applications exist for the Fibonacci sequence. The Fibonacci sequence is also employed in computer algorithms and the determination of the golden ratio. And Fibonacci retracement is a popular analysis tool in trade. In this article, we will learn two quick and suitable ways to make the Fibonacci sequence in Excel effective with appropriate illustrations. Here is the overview of our today’s task.

## Introduction to Fibonacci Sequence

Fibonacci sequence is a set of integers starting with 0 and 1. The next number in the sequence is found by adding the 2 numbers before it. So, our 1st and 2nd Fibonacci numbers are 0 and 1. So, our next number is 0+1=1. Similarly, the next number will be 1+1=2. In this way, we can easily calculate the following numbers in the sequence by summing the 2 previous numbers. So, the Fibonacci sequence is like 0, 1, 1, 2, 3, 5, 8….

## How to Create Fibonacci Sequence in Excel: 2 Suitable Ways

We will easily create the Fibonacci sequence using the Mathematical formula, and VBA macros as well. So, letâ€™s go through the steps one by one.

### Method 1: Use Mathematical Formula to Create Fibonacci Sequence in Excel

This section will apply the Mathematical formula to create a Fibonacci sequence in Excel. Letâ€™s follow the instructions below to create a Fibonacci sequence!

Steps:

• First of all, insert 0 and 1 in cells B5 and B6Â respectively.

• After that, select cell B7 and write down the below formula in that cell. The formula is,
`=B5+B6`
• Hence, simply press Enter on your keyboard. As a result, you will get 1 which is the third number of this sequence.

• Further, AutoFill the Mathematical formula up to B14.
• Finally, we will get our desired Fibonacci sequence.

• Now, we will see our Fibonacci sequence with the formula.

### Method 2: Run an Excel VBA Code to Create a Fibonacci Sequence in Excel

Now, we will create a User-Defined Function using the VBA Code to make a Fibonacci sequence in Excel. Letâ€™s follow the instructions below to create a Fibonacci sequence!

Step 1:

• Open a Module first; to do so, select the Developer tab and then click on,

Developer â†’ Visual Basic

• After clicking on the Visual Basic ribbon, a window named Microsoft Visual Basic for Applications will instantly appear in front of you. From that window, we will insert a module for applying our VBA code. To do that, go to,

Insert â†’ ModuleÂ

Step 2:

• Hence, the fibonacci_number module pops up. In the fibonacci_number module, write down the below VBAÂ code.
``````Option Explicit
Private Function FibNum(nthFib As Double) As Double
Dim x As Double
Dim y As Double
x = 1.618034 ^ nthFib - (1 - 1.618034) ^ nthFib
y = x / Sqr(5)
FibNum = Round(y)
End Function
Function FibonacciSeries(StartSr As Double, EndSr As Double) As Double()
Dim a As Double, b As Double, xy As Double
Dim xy() As Double
ReDim Preserve xy(EndSr - StartSr, 0)
xy = 0
For a = StartSr To EndSr
b = FibNum(a)
arr(xy, 0) = b
xy = 1 + xy
Next a
FibonacciSeries = arr
End Function
Sub Fibonacci_Number()
End Sub
```
```

• Hence, run the VBA To do that, go to,

Run â†’ Run Sub/UserForm

• After running the VBA Code, you will be able to create a user-defined function.
• Now, go to the Excel sheet, select cell B5, and write down the below function.
`=FibonacciSeries(0,9)`
• Then hit Now you will able to see the series of the first 10 numbers.

## Things to Remember

👉 You can pop up the Microsoft Visual Basic for Applications window by pressing Alt + F11 simultaneously. You can open the Microsoft Visual Basic Applications window by using the ALT + L + V shortcut as well.

👉 If a Developer tab is not visible in your ribbon, you can make it visible. To do that, go to,

File â†’ Option â†’ Customize Ribbon

## Conclusion

I’m hoping that all of the useful techniques for making a Fibonacci sequence after the last using VBA code will inspire you to use them to make your Excel spreadsheets more productive. If you have any questions or concerns, please feel free to remark in the comments section.
