What is the formula to calculate percentage?

There are various formulas you can use to calculate a percentage. Here are two of the most common methods.

Step 1: In this specific example, I’ll be calculating the difference between the profit and revenue. Select the cell you want the percentage to appear within. Now type in =(B2-C2)/B2. The / represents the division function.

Step 2: Press the Enter key on your keyboard in order to confirm the formula.

Step 3: In the toolbar, select the Percentage icon. In my example, there’s a 65% difference between the profit and revenue. If I change the profit amount to a higher figure, that percentage will decline.

Step 4: Another formula you can use to calculate percentage is simply applying the / key in between two cells. For example, to pass a driving theory test, I need to get 80% of the questions correct. To find out the percentage for this specific question, I’ve entered =B2/C2.

What is the easiest way to find percentages?

Now that we’ve explained how to calculate percentages, let’s take a look at the easiest way to find percentages via the drag feature.

Step 1: Select the cell where you’ve entered the formula to calculate a percentage.

Step 2: On the bottom-right corner of that cell, drag it down to where your column ends, or wherever you want percentages to be shown.

In my example, I’ve dragged it down to reveal the difference between the percentage of profit being generated compared to the revenue for each month that’s listed within my spreadsheet.

One of my favorite things about macOS is that it comes with default apps to handle your everyday tasks. You get Safari to browse the web, the Mail app to handle your emails, and the Preview app to open and view photos and PDFs.

But what if you want to use a third-party app you prefer over the default app? Thankfully, Apple makes it easy to change the default apps on your Mac. So, whether you want to use Google Chrome or Outlook, here’s how you can set them as the default on your Mac.

Microsoft is giving Copilot a quiet but meaningful redesign, and this time the focus is not just on making it more powerful. It is about making it feel like something that naturally belongs in your workflow.

Across Microsoft 365, Copilot is being reshaped to reduce visual noise and increase usefulness. Instead of constantly demanding attention, it is being designed to sit in the background when needed and step forward only when it actually helps.
