# 4 Best Free Fibonacci Calculator Software For Windows

Here is a list of **best free Fibonacci Calculator Software for Windows**. Through these software, you can find the *Fibonacci number of an nth digit*. The **nth** digit can be any number greater than **0**. Though most software have an **upper limit** for the **nth term** because the resultant Fibonacci number can become very large. As you know, Fibonacci numbers are generated by adding up previous two numbers, so after every addition, number gets bigger and bigger. Plus, time to find the Fibonacci number is also increased due to large calculations.

In all software, you just need to enter an **nth** value to get the respective Fibonacci number. In some software, you also get some additional information like *the whole Fibonacci sequence* and *the number of digits contained in a Fibonacci number*. Most software can also perform a lot more calculations than just Fibonacci numbers like **Factorials**, **Fractions**, **Linear equations**, etc.

### My Favorite Fibonacci Calculator Software For Windows:

**NH Mathematical Tools** is my favorite Fibonacci calculator because it can find Fibonacci numbers even for large **nth** values. Its speed to calculate the Fibonacci number is also quite fast. Plus, it can also perform calculations like **arithmetic**, **algebraic**, etc.

You can also check out lists of best free Boolean Expression Calculator, Factoring Cubics Calculator, and Punnett Square Calculator software for Windows.

## NH Mathematical Tools

**NH Mathematical Tools** is a **free Fibonacci Calculator Software** for Windows. Using it, you can find out the correct Fibonacci number for an entered **nth** digit. It also lets you know the *exact number of digits* in the obtained Fibonacci number as it can be a very large number. To create a better understanding of Fibonacci numbers, this software provides a *Fibonacci number definition* along with an *example*. The option to find out the Fibonacci number is available in **Sequence** > **Fibonacci number menu**.

Finding out the Fibonacci number is a straightforward process in which you need to press the **lookup button** after submitting the **nth** value to get the result in the **result section**. This software is capable of finding out the Fibonacci number for an **nth** value of up to **30000** with ease. Anything above **30000** may result in the software crash. Still, it is the only software that can find out the Fibonacci number for such a big **nth** value. The obtained result can be saved as **TXT**, **RTF**, and **DOC** file formats. Plus, some personalization tools like *changing the digits color*, *changing result box background color*, etc. are also available.

Besides Fibonacci, this software can also perform other calculations like **Algebra**, **Arithmetic**, **Probability**, **Sequence**, and more.

## FibClass

**FibClass** is a **free command prompt based Fibonacci calculator** software for Windows. It is also a portable software, that allows you to carry it in a portable storage device and use it on the go. When you launch this software, it will ask you to enter the command to give you the respective Fibonacci number. In response, you need to enter the **nth** value after the command **fib**, e.g.** fib 20**. Do not forget to put a space between the **command** and **nth** value. After that, just press enter to get the correct Fibonacci number. Apart from the Fibonacci number, it also provides the *exact number of digits* *contained in the obtained Fibonacci number*.

The biggest advantage of this software is that it can calculate the Fibonacci number for an nth value that can go up to a **million**. Though, the calculation for a big **nth** value can take a considerable amount of time. Still, it is one of the simplest software to find out the Fibonacci number.

## Calculatormatik

**Calculatormatik** is another free Fibonacci Calculator Software For Windows. Through this software, you can easily find out the *right Fibonacci number of an nth digit*. You can enter any digit between **0** and **100** as input to find the respective Fibonacci number of that **nth** digit. As you know, Fibonacci number or sequence is calculated by adding the previous two numbers, so after each addition, number of digits in the sum gets bigger and bigger. To restrict the Fibonacci number to get too big, it only allows you to enter the **nth** value up to **99**. Still, at **99th** value, the obtained Fibonacci number consists of **21** digits which is quite big.

Apart from calculating the Fibonacci number, it can also perform a lot more **calculations** and **unit conversions,** like **acceleration converter**, **area calculator**, **prime factor calculator**, etc. A list of all converters and calculators are present on its interface, just select any one of the tools and enter input values to get the desired result.

## Simponacci

**Simponacci** is a *java based Fibonacci calculator software* for Windows. It is a dedicated software to find out the Fibonacci number. But instead of showing the Fibonacci number of an **nth** value, it shows the Fibonacci number for **(N-1)th** number. *(N-1)th* means, if you enter **20** as **nth** value, then it shows Fibonacci number for **19**. The unique property of this freeware is that it shows the Fibonacci number of each value between **1** and **(N-1)th**.

To get the Fibonacci number using this software, you just need to press the **Fib it! button** after entering the **nth** value. On the left side, you will get the whole Fibonacci sequence along with the final Fibonacci number for **(n-1)th** value.

**Note**: This software displays inaccurate results when the entered **nth** number crosses the 48th number.
