How to add a countdown timer to PowerPoint

PowerPoint has no countdown timer built in. The easiest fix: paste our free timer slides into your deck. They count down by themselves.

1. Download free timer slides

Each slide shows the time left and moves on after one second, so the countdown runs on its own and ends on a "Time's up!" slide.

Each file has one slide per second in large white numbers on a dark background, turning amber for the last ten seconds. They're free to use in any presentation, including at work or school.

Open the timer file in PowerPoint.
Click a slide in the thumbnail list on the left and press Ctrl+A (⌘+A on a Mac) to select them all, then copy.
In your own presentation, click where the timer should go in the thumbnail list and paste. If asked, choose Keep Source Formatting.
Present as usual. When you reach the timer, it counts down on its own and stops on "Time's up!". Click to continue to your next slide.

In PowerPoint for Microsoft 365 you can also use Home › New Slide › Reuse Slides to pull them in.

2. Build a short countdown with animations

For a 5 or 10 second countdown on a single slide:

Add a text box with 10 in large type. Copy it and change the copies to 9, 8, 7 … 1, stacked exactly on top of each other (use Arrange › Align to line them up). In Arrange › Selection Pane, order them so 10 is at the top of the list and 1 at the bottom.
Select the top number (10), go to Animations, and pick the Disappear exit effect. Set Start to After Previous and Delay to 01.00.
Repeat for each number down to 1, in order. Open the Animation Pane to check the order.

A shrinking bar works too: draw a long rectangle and give it a Wipe exit animation with the duration set to your countdown length, starting With Previous.

3. Show a live timer next to your slides

For longer or flexible timers, run a timer in your browser. Open the online timer (or the stage timer for speakers), press F for full screen, and switch to it with Alt+Tab. You can also add a link on a slide (Insert › Link) to a page like the 5 minute timer, so one click opens it during the show. For a class break, the visual timer is easy to read from the back of a room.

4. Use an add-in

In PowerPoint for Microsoft 365, go to Insert › Get Add-ins and search for "timer". Several free add-ins put a countdown on a slide. They need an internet connection, and some can't be used if your organization blocks add-ins, which is why the slide files above are the most reliable option.

Questions people ask

How do I add a timer to my PowerPoint?

The quickest way: download one of the free countdown files on this page, open it, select all its slides (Ctrl+A in the slide list), copy them, and paste them into your presentation where you want the timer. Each slide moves on by itself after one second, so it counts down on its own when you present.

Does PowerPoint have a built-in countdown timer?

No. Presenter View has a timer that counts up how long you've been presenting, but there is no countdown you can show the audience. You need timer slides, animations, an add-in or a separate timer window.

Will the timer slides work on a Mac?

Yes. The files use ordinary slide transitions set to advance after one second, which PowerPoint for Mac, Windows and the web all support.

Why doesn't my timer count down by itself?

The slides only advance automatically in Slide Show mode. Also check Slide Show › Set Up Slide Show: Using timings, if present must be ticked, or PowerPoint ignores the one-second timings.

Can I change the colors or font?

Yes. Select all the timer slides and change the background or the text like any other slide. The one-second timing stays as long as you don't change the transition settings.

How do I add a timer in Google Slides?

Google Slides has no per-slide timings, but you can import these slides (File › Import slides) into their own presentation and present it with Auto-play set to every 1 second. Or open the online timer in another window.
