How to Calculate Ratio in Excel

Share this

Excel is one of the most widely used spreadsheet programs in the world, and for good reason. It offers many powerful features that make data analysis a breeze, and one of those features is the ability to calculate ratios. Ratios are an important tool for analyzing data, and in this article, we will take a deep dive into how to calculate ratios in Excel.

Understanding the Importance of Ratios in Excel

Before we calculate ratios in Excel, let's understand why they are so important. Ratios compare different aspects of a business or operation, providing insights into its financial health and overall performance. For example, a company might use ratios to measure profitability, liquidity, or efficiency.

Furthermore, ratios can also be used to compare a business to its competitors or industry benchmarks. This allows companies to identify areas where they may be falling behind or excelling compared to others in their field. By understanding these ratios, businesses can make informed decisions about where to allocate resources and how to improve their operations.

The Basics of Ratio Calculation in Excel

The basic formula for calculating a ratio is to divide one number by another. For example, if you want to calculate the ratio of profit to revenue, you would divide the profit by the revenue. To do this in Excel, you can type in the formula: =profit/revenue. Excel will then calculate the ratio and display the result in the cell.

It is important to note that ratios can also be expressed as percentages. To convert a ratio to a percentage, you simply multiply the ratio by 100. For instance, if the profit-to-revenue ratio is 0.25, you can convert it to a percentage by multiplying it by 100, resulting in a percentage of 25%.

Furthermore, ratios can be used to compare different sets of data. For example, you can use ratios to compare the revenue of two different companies or the sales of two different products. By calculating and comparing ratios, you can gain valuable insights into the performance of different aspects of your business.

Step-by-Step Guide to Calculating Ratios in Excel

Here is a step-by-step guide to calculating ratios in Excel:

  1. Identify the data points you want to use to calculate the ratio.
  2. Select the cell where you want to display the ratio.
  3. Type in the formula for the ratio using the appropriate cell references. For example, to calculate the debt-to-equity ratio, you would type in =debt/equity.
  4. Press enter, and Excel will calculate the ratio and display the result in the cell.

It is important to note that while Excel does not have specific functions named after common financial ratios like the current ratio or the quick ratio, you can still calculate these ratios by manually creating the formulas using the appropriate cell references.

In Zebra BI Tables for Office, you can add a custom formula with just a few clicks. Let’s add this one:

Gross Profit = Sales – COGS

Additionally, Excel allows you to create charts and graphs to represent your ratio calculations visually. This can be helpful in identifying trends and patterns in your data. To create a chart or graph, select the data points you want to include and click on the "Insert" tab. From there, you can choose the type of chart or graph you want to create and customize it to fit your needs.

Zebra BI Charts are the perfect tool for visualizing ratio trends. They follow the best practices outlined in IBCS standards to ensure clear and meaningful insights from your data.

Using Formulas to Calculate Ratios in Excel

Unfortunately, Excel does not have built-in formulas for calculating ratios, but it allows you to create custom formulas for ratios that may not be included in the built-in formulas. This can be done by using a combination of mathematical operators and cell references. Custom formulas can be saved and reused for future calculations, saving time and effort.

It is important to note that when using formulas to calculate ratios in Excel, you must ensure that the data you are using is accurate and up-to-date. If the data is incorrect, the ratios calculated will also be incorrect, which can lead to poor decision-making.

How to Calculate Simple Ratios in Excel

Calculating simple ratios in Excel is straightforward. A simple ratio involves comparing two numbers, such as profit and revenue. To calculate a simple ratio in Excel, divide one number by the other using the formula =number1/number2. For example, to calculate the profit margin, you would divide the profit by the revenue.

It is important to note that when calculating ratios in Excel, you should format the cell as a percentage to make it easier to read. To do this, select the cell with the ratio, right-click, and choose "Format Cells." Then, select "Percentage" under the "Number" tab.

How to Calculate Complex Ratios in Excel

Some ratios involve comparing multiple data points, such as the Altman Z-Score, which measures a company's financial health. Calculating complex ratios in Excel may require more complicated formulas or functions. However, Excel offers a wide range of tools and functions that make complex calculations much easier.

One of the most useful tools for calculating complex ratios in Excel is the Pivot Table. This tool allows you to quickly summarize and analyze large amounts of data, making it easier to identify trends and patterns. Additionally, Excel's built-in charting tools can help you visualize your data and communicate your findings to others.

For next-level data analysis and exploration, you should use Zebra BI visuals that can use a pivot table as a data source. However, the added value is in cross-visual filtering, which users usually use from Power BI.

Another important consideration when calculating complex ratios in Excel is data accuracy. It's important to ensure that your data is accurate and up-to-date, as even small errors can have a significant impact on your calculations. To help ensure data accuracy, consider using Excel's data validation tools, which can help you identify and correct errors in your data.
