Ask someone how long they spent on their last deck and they'll tell you about the content — the argument, the data, the story. Ask them how much of that time went to nudging a bullet point half a centimeter to the left, and the answer gets quieter. Nobody budgets for that part. It just happens.

There's a number that keeps surfacing whenever anyone actually measures this instead of guessing at it. A survey conducted by GfK on behalf of Made in Office, covering more than a thousand office workers, found that employees spend an average of about 20 hours a month working in PowerPoint — and roughly 8 of those hours go specifically to formatting rather than content. Not writing, not structuring an argument, not deciding what the audience needs to hear. Formatting.

Where the Eight Hours Actually Go

I've watched people push back on that number the first time they hear it — "eight hours sounds high" — right up until they list out what they did in a deck the week before. Aligning a chart that shipped from an old file in a different font. Re-checking three versions of the same slide because nobody was sure which one was current. Rebuilding a table because the source presentation used a color palette from two rebrands ago.

The GfK research breaks the formatting time into fairly mundane categories: designing and formatting visually appealing slides, getting tables and charts to line up correctly, converting old slides into a new template, and hunting for the right image or icon. None of these individually sounds like eight hours. Stacked across a month of decks, they add up in a way that's easy to underestimate because each instance feels small.

One thing people overlook is that most presentations aren't built from a blank slide. The same research found that roughly 78% of decks are created from existing slides rather than from scratch. That sounds efficient in theory — why rebuild what already exists? — but in practice it's often where the formatting tax gets paid. An inherited slide carries an old font, an old color, a layout built for a different aspect ratio. Reusing it doesn't save the formatting work; it just relocates it to a different point in the process.

The Number Nobody Likes to Say Out Loud

Here's the part that tends to get skipped in the write-ups of this study: it's not just that formatting eats time, it's that the time doesn't buy design compliance. The same survey found that around 70% of presentations still don't follow their company's corporate design standards, even after all those formatting hours. That's the uncomfortable bit. If eight hours a month actually produced eight hours' worth of brand-consistent output, the number would be easier to accept. Instead, a lot of that time goes toward fixing things that then drift out of alignment again on the next deck, because the underlying template or slide library wasn't the problem being solved.

This is worth sitting with for a second, because it changes what the fix should look like. If formatting time were simply a matter of people working carefully, more time would eventually produce compliant decks. It doesn't. Which suggests the bottleneck isn't effort — it's that people are formatting from inconsistent source material in the first place.

Why This Hasn't Gone Away With Better Tools

I'd expect a stat like this to have shrunk by now — AI drafting tools, smarter templates, design assistants built into PowerPoint itself. And to some extent, prep time for a simple deck has dropped; some more recent industry write-ups put a basic 10-slide presentation at under two hours of prep, down from two to three hours a couple of years earlier. But that's prep time for a fresh, simple deck. It doesn't touch the specific problem the GfK numbers describe, which is the drag created by reused content, mismatched templates, and searching for the right version of a slide that already exists somewhere in the company.

Automation tools help with the mechanical part — realigning shapes, applying a color scheme in bulk. What they don't fix is the upstream mess: a marketing deck built on a 2019 template, a sales deck with three different chart styles because it was stitched together from two other presentations. No amount of speed on the editing side solves a structural problem in the source material.

What Actually Moves the Number

In my experience, the decks that don't bleed formatting hours share one trait: someone decided the layout in advance, instead of discovering it slide by slide. A pre-built structure — where the chart style, spacing, and color logic are already locked in — removes the decision-making that eats the bulk of formatting time. You're not asking "does this look right," you're filling in numbers.

That's a different claim from "use a template," which is the kind of advice that shows up in every article on this topic and means almost nothing on its own. The distinction that matters is whether the template was actually built for the kind of chart or diagram you're producing, or whether it's a generic shell you're bending to fit. A quarterly review built from a properly structured chart template designed for that specific comparison doesn't need the axis, legend, and color rework that a repurposed generic slide does — because those decisions were already made correctly the first time.

The Part That's Easy to Miss

None of this means formatting doesn't matter. A sloppy deck undermines the message it's carrying, and the GfK numbers make clear that people know this — that's exactly why they're spending eight hours a month on it. The issue isn't that formatting is unimportant. It's that most of that time isn't going toward making the content clearer; it's going toward correcting inconsistency that shouldn't have existed in the first place.

If a deck already draws on a consistent, purpose-built slide template — masters, color variables, layout logic already decided — formatting stops being a design decision made under deadline pressure and becomes something closer to filling in a form. That's a smaller, less interesting task, and honestly, that's the point.

Next time you catch yourself nudging a shape by two pixels at 9pm the night before a client meeting, it's worth asking whether that's a formatting problem or a starting-point problem. Usually it's the second one.
