What Is Normal CPU Usage?

The CPU usage is different based on different cases and we will show you CPU usage at various times: when idle, when running other apps, when gaming, etc.

What Is a Normal Amount of CPU Usage in Windows 10

For almost CPU or OS, an average CPU percentage is below 10% at idle. This mainly depends on what apps are running on your PC.

In Windows 10, if you are using a decent GPU, CPU, and SSD, the normal CPU usage is around 2% to 4% at idle. This means no CPU intensive tasks are running, you are not doing anything and after-update checks or Windows 10 updates aren’t running. Then, the CPU usage is that.

If you read regular blogs online, the normal CPU usage is from 5% to 15%; it is 20-40% if you use a large Google Sheet and the CPU usage can reach up to 50% if you open multiple tabs at once. If you open 30 tabs a time, it will reach 100% but quickly go back to below 10%.

CPU usage in Task Manager

If you are running a common PC, the normal CPU usage in Windows 10 is:

  1. At idle: 2-4%
  2. Windows 10 boot: high in a short period time, then below 5%
  3. When browsing: 5-15% (sometimes 30%)
