The quickest calculator shortcut key on Windows is Win + R: type calc in the Run box and press Enter. Calculator opens in under a second. Pressing Win alone and typing calc works the same way through the Start menu.
Windows has no built in single key for Calculator, but many keyboards include a Calculator key above the number pad, and you can create your own key combination in two minutes, as shown below.

Make a one key calculator shortcut
- Press Win, type calculator, and right click it. Choose Pin to Start or Pin to taskbar.
- For a key combination, make a desktop shortcut whose location is calc.exe and call it Calculator.
- In that shortcut's Properties, put the cursor in the Shortcut key field and hit Ctrl + Alt + C, or any free combination.
- Click OK. That combination now opens Calculator from anywhere.
Pinned taskbar apps also open with Win and their position number: if Calculator is third on the taskbar, Win + 3 opens it. Pressing the same combination again switches back to it if it is already open.

Calculator shortcut key in laptop keyboards
Laptops rarely have a Calculator key, and many have no number pad either. The Win + R method or a pinned taskbar icon is the fastest choice. Accountants often use the calculator panel built into their accounting software instead, opened with Ctrl + N; see our accounting calculator page.
