The article will show you how to calculate the CAGR (Compound Annual Growth Rate) in Excel with negative numbers. Basically, it’s very easy to calculate the CAGR when the data are positive. Which means no loss involved in the business. However, the mathematical formula for the CAGR prohibits generating an output when the loss is in consideration. Fortunately, this article will pave the way to get rid of this problem.

## What Is CAGR?

A mutual fund or bond’s rate of return is measured by a Compound Annual Growth Rate (**CAGR**) over an investment period of five or ten years. The **CAGR** assesses the growth of an investment as if it had increased at a constant rate on an annually compounded basis, hence the name “smoothed” rate of return.

## How to Calculate CAGR with Negative Number in Excel: 2 Perfect Ways

In the dataset, you will see the profit data of a company for 4 years. The last one is the target profit (profit data in 2021). To achieve this, we will calculate what the **CAGR** value should be.

The mathematical formula to calculate the **CAGR **is given below.

**1. Using Excel ABS Function to Calculate CAGR with Negative Number**

As the fractional root of a negative number returns complex values, we will use **the ABS functions **to calculate the absolute values of negative profit (loss in business) to calculate the **CAGR**. Let’s go through the process below.

**Steps:**

- First, insert the data of profit in the observing years.
- Next, type the following formula in the cell.

`=((C5-F5+ABS(F5))/ABS(F5))^(1/(C4-F4))-1`

The formula is derived from the CAGR formula we showed in the previous section. The **ABS** function makes the loss value positive and thus removes the complex number dilemma.

- After that, press the
**ENTER**button and you will see the**CAGR**value for the data we use in this sheet.

Thus you can calculate the **CAGR **by using the Excel **ABS **function with negative numbers.

**2. Applying Goal Seek Analysis to Calculate CAGR with a Negative Number**

Another effective way to calculate the **CAGR **is to use the **Goal Seek **analysis feature from the **Data** Tab. Let’s follow the instructions below.

**Steps:**

- First, set the initial profit and target profit. Also, choose a
**CAGR**of your choice. As our topic focuses on negative numbers, we are considering that the company made a loss in the first year. - After that, type the following formula in cell
**C5**.

`=C10+ABS(C10)*$C$12`

The formula will return the principal after a year with a **CAGR **of 15% referenced by cell **C12**. Note that we are using the** ABS** function to get rid of negative values.

- Later, type another similar formula in cell
**C6**.

`=C5+ABS(C5)*$C$12`

This formula also returns the principal in the second year.

- Thereafter, use the
**Fill Handle**to**AutoFill**the lower cells.

- Next, go to
**Data**>>**Forecast**>>**What if Analysis**>>**Goal Seek**.

- Thereafter, select
**C8**as the**Set Cell**. Because we want to find out the**CAGR**by making the value of this cell to our target value (**12000**). - As a result, the ‘
**To Value**’ will be**12000**. - The
**CAGR**will be determined in cell**C12**. So we selected it for the ‘**By Changing Cell**’ section. - After that, click
**OK**.

- Finally, this operation will provide you with the
**CAGR**based on this dataset.

Thus you can calculate **CAGR **in Excel with a negative number.
